As more electronic devices utilize communication networks (e.g., wireless communication networks), the communication networks may become more congested with communication traffic. Further, multiple electronic devices may send electronic communications via the same communication channel, which may result in increased interference. For example, Wi-Fi typically operates in one or more bands (e.g., 2.4 GHz, 5 GHz, etc.), and electronic devices that utilize Wireless Personal Area Networks (WPANs), such as ZigBee, may also utilize the 2.4 GHz band. However, when two electronic devices communicate on the same band, interference may occur with the communications such that one device's communication may be over powered by the other device's communication. For example, electronic devices that utilize WPANs may be low powered devices, such as Internet of Things (IoT) devices, which have low powered communications. Thus, the communications from IoT devices may be overpowered by the communications from Wi-Fi devices when both the IoT devices and the Wi-Fi devices utilize the same wireless band.
It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and are not restrictive. Methods and systems for wireless communication are described. A wireless device (e.g., an IoT device) may communicate with a network device (e.g., a gateway, a router, etc.) to pair the wireless device with the network device directly or via a wireless network. The wireless device may provide the network device with one or more characteristics of the wireless device to facilitate communication with the network device. The wireless device may communicate with the network device via a first wireless network. The network device may utilize the characteristics of the wireless device to determine a time period that the wireless device may communicate with the network device via the first wireless network. The network device may receive connection characteristics from the wireless device. The network device may receive the connection characteristics after the wireless device's location has changed. The network device may modify a power level of a second wireless network based on the connection characteristics after the wireless device's location has changed. The network device may reduce the power level of the second wireless network during the time period to improve the ability of the network device to receive communications from the wireless device. Further, the network device may concatenate one or more communication bands to improve the ability of the network device to receive communications from the wireless device. This summary is not intended to identify critical or essential features of the disclosure, but merely to summarize certain features and variations thereof. Other details and features will be described in the sections that follow.

This detailed description may refer to a given entity performing some action. It should be understood that this language may in some cases mean that a system (e.g., a computer) owned and/or controlled by the given entity is actually performing the action.
When a network device (e.g., a gateway, a router, an access point, etc.) utilizes more than one communication protocol, problems may arise when attempting to utilize one or more radios concurrently. For example, under normal usage of a Wi-Fi network, some communication protocols may be adversely affected because the communication protocols are low powered compared to Wi-Fi. One method for improving the communication capabilities of the low powered protocols is to have a designated time period (e.g., a quiet time) that the Wi-Fi devices are not communicating on the Wi-Fi network so that the low powered protocol has a clean (e.g., noise free) time window to communicate with the network device. However, this may negatively impact a user's experience when utilizing the Wi-Fi network. Further, this approach may be extremely resource intensive and waste resources because the Wi-Fi quiet time occurs irrespective of the time of day and does not take into account the utilization of the Wi-Fi network.
A wireless network device may pair with a wireless device (e.g., an Internet of Things (IoT) device). During the pairing process, the wireless network device and the wireless device may determine a polling time for the wireless device to communicate with the wireless network device. The communications between the wireless device and the wireless network device may have one or more connection attributes, such as a Link Quality Indicator (LQI), a Relative Received Signal Strength (RSSI), a Packet Error Rate (PER), and the like. If the one or more connection attributes change (e.g., if a location of a wireless device changes), the changed connection attributes may be factored into a polling frequency, as well as an adjustment to the power level of a wireless network (e.g., Wi-Fi) associated with the wireless network device to accommodate receiver sensitivity for the wireless device. Thus, the communications from the wireless device may have better noise isolation, and the ability for the wireless network device to receive communications from the wireless device may be increased.
The wireless network device may concatenate one or more bands of a wireless network to improve the signal to noise ratio of communications from the wireless device. A wireless network may have one or more communication bands. For example, a Wireless Personal Area Network (WPAN), such as ZigBee, may have one or more communications bands. The bands may each have an associated width (e.g., 2 MHz wide). Further, each of these bands may be spaced a certain value apart. For example, the bands may be 5 MHz apart. In comparison, a Wi-Fi network may have bands that are 20 MHz or 40 MHz wide that operate on the same channel as the WPAN. Thus, if the WPAN and Wi-Fi network are communicating concurrently, the communications of the WPAN may be very noisy due to the low signal bandwidth as compared to the Wi-Fi network. Accordingly, the communications of the WPAN network may not be received by the wireless network device when a Wi-Fi communication is actively transmitting on the Wi-Fi network since the Wi-Fi network and the WPAN network may utilize the same channel. While a Wi-Fi network and a WPAN network have been described for ease of explanation, a person skilled in the art would appreciate that interference may occur between any wireless communication operating on the same wireless band. Thus, the present disclosure should not be limited to the aforementioned examples.
To improve the ability for the wireless network device to receive communications via a first wireless network, the wireless network device may concatenate two or more bands of the first wireless network when the wireless network device is not actively transmitting via the first wireless network. By concatenating two or more bands of the first wireless network, the concatenated bands have a larger bandwidth which may be approximately as wide as a second wireless network band to improve the Signal to Noise Ratio (SNR) of the first wireless band. Further, concatenating bands of the first wireless network will not disrupt other networks (e.g., the second wireless network) because it is a passive mechanism (e.g., a mechanism that does not require an active reduction of the second wireless network) that is employed when the wireless network device is in a receive mode to counter coexistence of the first wireless network and the second wireless network. When the wireless network device sends (e.g., transmits) a communication via the first wireless network, the wireless network device may only send the communication on one channel of the first wireless network, instead of the concatenated band.
For example, the wireless network device may concatenate two or more bands of a WPAN when the wireless network device is not actively transmitting via the WPAN. That is, the wireless network device may concatenate two or more bands of the WPAN when the wireless network device is listening and/or receiving communications via the WPAN. By concatenating two or more bands of the WPAN, the concatenated bands have a larger bandwidth which may be approximately as wide as a Wi-Fi band to improve the Signal to Noise Ratio (SNR) of the WPAN. Further, concatenating bands of the WPAN will not disrupt other networks (e.g., the Wi-Fi network) because it is a passive mechanism (e.g., a mechanism that does not require an active reduction of the Wi-Fi network) that is employed when the wireless network device is in a receive mode to counter coexistence of the WPAN and the Wi-Fi network. When the wireless network device sends (e.g., transmits) a communication via the WPAN, the wireless network device may only send the communication on one channel of the WPAN, instead of the concatenated band.
The system 100 may have a network device 102, computing devices 104, and/or wireless devices 106. Specifically, the system 100 has computing devices 104a,b,c and wireless devices 106a,b. As will be appreciated by one skilled in the art, the system 100 may have any quantity of network devices 102, computing devices 104, and wireless devices 106. The network device 102 may be a wireless communication device (e.g., a wireless router, a gateway, an access point, etc.). The network device 102 may utilize two or more communication protocols to communicate on two or more wireless networks. The network device 102 may have two more radio transceivers for utilizing the two or more communication protocols. A first wireless network and a second wireless network may communicate via the same channel. For example, the network device 102 may utilize a Wi-Fi communication protocol and may utilize a Wireless Personal Area Network (WPAN) protocol to provide two separate communication networks. The WPAN may be a ZigBee network. The Wi-Fi network and the WPAN may communicate via the same channel (e.g., a 2.4 GHz channel). The network device 102 may be configured with a first Service Set Identifier (SSID) (e.g., associated with a user network or private network) to function as a local network for a particular user or users. The network device 102 may be configured with a second SSID (e.g., associated with a public/community network or a hidden network) to function as a secondary network or redundant network for connected communication devices.
The computing devices 104a,b,c may be an electronic device such as a computer, a smartphone, a laptop, a tablet, a set top box, a display device, or other device capable of communicating with the network device 102. The computing devices 104 may communicate with the network device 102 via a wireless communication network (e.g., Wi-Fi, Bluetooth, etc.). The computing devices 104 may utilize the wireless network to communicate with the network device 102. The computing devices 104 may communicate via the network device 102 to access a service, such as the Internet.
The wireless devices 106a,b may be any electronic device such as a computer, a smartphone, a laptop, a tablet, a set top box, a display device, and/or a low powered electronic device (e.g., an IoT device) such as a sensor, a smart device, a security system (e.g., electronic camera, smart doorbell, etc.), and so forth. The wireless devices 106 may utilize a first wireless network (e.g., a WPAN and/or Wi-Fi network) to communicate with the network device 102. The wireless devices 106 may pair with the network device 102. The wireless devices 106 may pair with the network device 102 prior to communicating via the first wireless network (e.g., the WPAN and/or Wi-Fi network). The wireless devices 106 may provide one or more communication characteristics and/or attributes of the wireless devices 106 to the network device 102, such as Link Quality Indicator (LQI), Relative Received Signal Strength (RSSI), Packet Error Rate (PER), and so forth. The wireless devices 106 may provide the one or more communication characteristics and/or attributes of the wireless devices 106 to the network device 102 during the pairing process.
The wireless devices 106 may provide the network device 102 with a time period that the wireless devices 106 may send a communication to the network device 102. The wireless devices 106 may communicate with the network device 102 to determine the time period that the wireless devices 106 may send a communication to the network device 102. The communication may be one or more data packets sent from the wireless device 106 to the network device 102, such as a heartbeat signal. The network device 102 may keep track of (e.g., store in a data structure) a time period associated with each wireless device 106 that has paired with (e.g., registered with) the network device 102. The network device 102 may determine a time for each wireless device 106 to communicate with the network device 102. The network device 102 may determine, based on the time period, a time for each wireless device 106 to communicate with the network device 102. The network device 102 may ensure that no two wireless devices 106 are communicating during the same time period in order to avoid any interference between the communications of the wireless devices 106. That is, the network device 102 may determine non-overlapping time periods for each wireless device 106 to communicate with the network device 102. One or more of the wireless devices 106 may not be capable of modifying the time period that the wireless device 106 sends the communication to the network device 102. Accordingly, the network device 102 may only modify the time period of wireless devices 106 that are capable of modifying the time period that the wireless device 106 communicates with the network device 102.
After pairing with the network device 102, the wireless devices 106 may communicate with the network device 102 via the first wireless network. After pairing with the network device 102, a location of the wireless devices 106 may change. That is, during pairing, the wireless devices 106 may be placed close (e.g., a few inches, a foot, etc.) to the network device 102 to improve the pairing process. However, the final location of the wireless devices 106 may be further away from the network device 102, such as placed throughout a user's home. Thus, the communication characteristics may change based on the final location of the wireless devices 106. Accordingly, the network device 102 may modify and/or update one or more settings of one or more of the communication networks associated with the network device 102 based on the final location of the wireless devices 106.
The network device 102 may adjust one or more settings (e.g., a power level) of a wireless network associated with the network device 102. The network device 102 may adjust one or more settings of a first wireless network and/or a second wireless network. For example, the network device 102 may adjust one or more settings of the Wi-Fi network and/or the WPAN network. The network device 102 may adjust one or more settings of the wireless communication based on the final location of one or more of the wireless devices 106. The network device 102 may reduce a power level of one of the one or more wireless networks. For example, the network device 102 may reduce a power level of a signal and/or a communication associated with the wireless network. The network device 102 may reduce the power level of the wireless network during a time period that one or more of the wireless devices 106 may communicate with the network device 102. The network device 102 may determine the time period for when each wireless device 106 may communicate with the network device 102. The network device 102 may determine a window of time to adjust the one or more settings of the wireless network. The network device 102 may determine the window of time to adjust the one or more settings of the wireless network based on the time period when the wireless devices 106 communicate with the network device 102. The window of time may be any period of time (e.g., 1 ms, 5 ms, etc.). The window of time may be centered around the time period when the wireless devices 106 communicate with the network device 102. For example, if the wireless device 106a communicates with the network device 102 every 20 ms, the network device 102 may adjust the one or more settings of the wireless network from every 18 ms to 22 ms. Stated differently, the network device 102 may adjust the one or more settings of the wireless network at 18 ms, and then may adjust the one or more settings of the wireless network back to normal (e.g., the one or more settings standard operational value) 4 ms later at 22 ms. Thus, the window of time may be 4 ms (e.g., from 18 ms to 22 ms).
The network device 102 may adjust the time period that the wireless devices 106 communicate with the network device 102. The network device 102 may adjust the time period that the wireless devices 106 communicate with the network device 102 based on a signal strength of communications received from one or more of the wireless devices 106. The network device may increase (e.g., lengthen) the time period that a wireless device 106 communicates with the network device 102. The network device 102 may increase the time period that the wireless device 106 communicates with the network device 102 to reduce the number of communications sent by the wireless device 106 to the network device 102. By reducing the number of communications sent by the wireless device 106 to the network device 102, power of the wireless device 106 may be conserved. By conserving the power of the wireless device 106, the wireless device 106 may increase the power per communication sent. By increasing the power per communication sent by the wireless device 106, the communications may have an increased chance of being received by the network device 102. The network device 102 may decrease (e.g., shorten) the time period that the wireless device 106 communicates with the network device 102 to increase the number of communications sent by the wireless device 106 to the network device 102. The network device 102 may also increase or decrease the time period based on a utilization of a wireless network (e.g., the Wi-Fi network and/or the WPAN network). While the network device 102 has been described as adjusting the time period for ease of explanation, the wireless device 106 may have the same capabilities described above.
The network device 102 may reduce the power level of the first network during the time period that one or more of the wireless devices 106 may communicate with the network device 102 utilizing the second wireless network. For example, the network device 102 may reduce a power level associated with a signal associated with the first wireless network and/or a power level of a communication associated with the first wireless network. The network device 102 may reduce the power level of the first wireless network based on the communication characteristics associated with one or more of the wireless devices 106. The network device 102 may reduce the power level of the first wireless network based on a signal strength of communications received from one or more of the wireless devices 106. The network device 102 may reduce the power level of the first wireless network based on a distance of one or more of the wireless devices 106 from the network device 102. That is, the further the final location of a wireless device 106 is from the network device 102, the network device 102 may further reduce the power level of the first wireless network to ensure the wireless device 106 is capable of communicating with the network device 102 via the second wireless network. The network device 102 may modify one or more channels of the first wireless network to avoid conflict with the second wireless network. The network device 102 may reduce the channel bandwidth of the first wireless network. The reduction in the channel bandwidth may increase frequency separation to improve the wireless devices 106 ability to communicate on the second wireless network.
For example, the network device 102 may reduce the power level of the Wi-Fi network during the time period that one or more of the wireless devices 106 may communicate with the network device 102. The network device 102 may reduce the power level of the Wi-Fi network based on the communication characteristics associated with one or more of the wireless devices 106. The network device 102 may reduce the power level of the Wi-Fi network based on a signal strength of communications received from one or more of the wireless devices 106. The network device 102 may reduce the power level of the Wi-Fi network based on a distance of one or more of the wireless devices 106 from the network device 102. That is, the further the final location of a wireless device 106 is from the network device 102, the network device 102 may further reduce the power level of the Wi-Fi network to ensure the wireless device 106 is capable of communicating with the network device 102 over the WPAN network. The network device 102 may modify one or more channels of the Wi-Fi network to avoid conflict with the WPAN. The network device 102 may reduce the channel bandwidth of the Wi-Fi network. The reduction in the channel bandwidth may increase frequency separation to improve the wireless devices 106 ability to communicate on the WPAN. For example, the network device 102 may reduce the channel bandwidth from 40 MHz to 20 MHz.
The network device 102 may modify the reduction of the power level of the first wireless network based on when a wireless device 106 is communicating with the network device 102. For example, the network device 102 may modify the reduction of the power level of the Wi-Fi network based on when a wireless device 106 is communicating with the network device 102 (e.g., via the WPAN). Each wireless device 106 may communicate with the network device 102 at different times. The network device 102 may determine a power level reduction for each wireless device 106. The power level reduction may be based on the time period that the wireless device 106 may communicate with the network device 102. The network device 102 may modify the power level of the first wireless network based on which wireless device 106 may be communicating with the network device 102 during the time period. For example, the network device 102 may modify the power level of the Wi-Fi network based on which wireless device 106 may be communicating with the network device 102 during the time period. The power level reduction for each wireless device 106 may be unique. While the power level reduction for each wireless device 106 may be unique, the power level reduction may be the same for two or more wireless devices 106. The power level reduction may be based on one or more communication characteristics of the communication between the network device 102 and each wireless device 106.
The network device 102 may determine a window of time to reduce the power level of the first wireless network. The network device 102 may determine the window of time to adjust reduce the power level of the first wireless network based on the time period when the wireless devices 106 communicate with the network device 102 via the second wireless network. For example, the network device 102 may determine the window of time to adjust (e.g., reduce) the power level of the Wi-Fi network based on the time period when the wireless devices 106 communicate with the network device 102 via the WPAN. The window of time may be any period of time (e.g., 1 ms, 5 ms, etc.). The window of time may be centered around the time period when the wireless devices 106 communicate with the network device 102. For example, if the wireless device 106a communicates with the network device 102 every 20 ms, the network device 102 may reduce the power level of the first wireless network from every 18 ms to 22 ms. Stated differently, the network device 102 may reduce the power level of the first wireless network at 18 ms, and then may adjust the power level of the first wireless network back to normal (e.g., the one or more settings standard operational value) 4 ms later at 22 ms. Thus, the window of time may be 4 ms (e.g., from 18 ms to 22 ms).
The wireless device 106a may communicate with the network device 102 every 10 ms. The network device 102 may determine a power level of the first wireless network for when the wireless device 106a may communicate with the network device 102 (e.g., every 10 ms). The network device 102 may determine a power level reduction of the first wireless network for the time period that the wireless device 106a may communicate with the network device 102. The network device 102 may determine a window of time to reduce the power level of the first wireless network. The window of time may be based on the time period that the wireless device 106a may communicate with the network device 102.
The wireless device 106a may send data to the network device 102. The data may indicate a signal strength associated with the communication between the network device 102 and the wireless device 106a. The network device 102 may determine, based on the signal strength, a power level reduction of the first wireless network. For example, the network device 102 may determine that the power level of the Wi-Fi network may need to be reduced 20% based on the signal strength. The network device 102 may reduce the power level of the Wi-Fi network by 20% when the wireless device 106a communicates with the network device 102. The network device 102 may determine that the power level of the first wireless network may need to be reduced by 45% based on a signal strength associated with the communication from the wireless device 106b via the second wireless network. For example, the network device 102 may reduce the power level of the Wi-Fi network by 45% when the wireless device 106b communicates with the network device 102 via the WPAN.
The network device 102 may determine a power level reduction and a time period for the power level reduction for each wireless device 106 paired with the network device 102. The network device 102 may determine a respective power level reduction, a respective time period for the power level reduction, and a respective window of time to reduce the power level of the first wireless network for each wireless device 106 paired with the network device 102. For example, the network device 102 may determine a respective power level reduction, a respective time period for the power level reduction, and a respective window of time to reduce the power level of the Wi-Fi network for each wireless device 106 paired with the network device 102.
The network device 102 may reduce the power level of the first wireless network a first power level reduction (e.g., 20%) during a time period that the wireless device 106a may communicate with the network device 102 via the second wireless network. For example, the wireless device 106a may communicate every 10 ms with the network device 102. The network device 102 may determine to modify the power level of the Wi-Fi network 20% every 10 ms to improve communication with the wireless device 106a via the second wireless network (e.g., the WPAN).
The network device 102 may determine a window of time to reduce the power level of the first wireless network. The network device 102 may determine to reduce the power level of the first wireless network for a 4 ms window of time. For example, the network device may determine to reduce the power level of the Wi-Fi network from 8 ms to 12 ms (e.g., a 4 ms window of time every 10 ms). The network device may determine to reduce the power level of the Wi-Fi network 20% from 8 ms to 12 ms to improve communications with the wireless device 106a via the second wireless network (e.g., the WPAN). The network device 102 may reduce the power level of the first wireless network a second power level reduction (e.g., 45%) during a time period that the wireless device 106b may communicate with the network device 102. For example, the wireless device 106b may communicate every 15 ms with the network device 102. The network device 102 may determine to modify the power level of the Wi-Fi network 45% every 15 ms to improve communication with the wireless device 106b via the second wireless network (e.g., the WPAN). The network device 102 may determine a window of time to reduce the power level of the first wireless network. The network device 102 may determine to reduce the power level of the first wireless network for a 2 ms window of time. The network device may determine to reduce the power level of the first wireless network from 14 ms to 16 ms (e.g., a 1 ms window of time every 15 ms). The network device may determine to reduce the power level of the first wireless network 45% from 14 ms to 16 ms to improve communications with the network device 106b via the second wireless network.
The network device 102 may dynamically modify the power level of the first wireless network (e.g., a Wi-Fi network) during the time period that one or more of the wireless devices 106 may communicate with the network device 102 via the second wireless network (e.g., a WPAN). The network device 102 may dynamically modify the power level of the first wireless network based on usage of the first wireless network. The network device 102 may increase or decrease the power level of the first wireless network based on usage of the first wireless network. The network device 102 may determine a network utilization of the first wireless network. The network device 102 may determine the network utilization of the first wireless network based on a usage of the first wireless network by the computing devices 104. The network device 102 may determine the network utilization of the first wireless network based on the available bandwidth of the first wireless network. If the computing devices 104 are heavily using the first wireless network (e.g., performing bandwidth intensive tasks such as streaming high definition content), the network device 102 may not reduce the power level of the first wireless network in order to ensure that a user utilizing the computing devices 104 does not have a negative experience while heavily using the first wireless network. The network device 102 may modify the reduction of the power level of the first wireless network based on the usage of the first wireless network by the computing devices 104. The network device 102 may reduce the power level of the first wireless network if the computing devices 104 are not utilizing a large portion of the first wireless network bandwidth in order to improve communications with the wireless devices 106.
The network device 102 may determine to not reduce the power level of the first wireless network during a first time period that one or more of the wireless devices 106 may communicate with the network device 102 via the second wireless network. For example, the network device 102 may determine to not reduce the power level of the Wi-Fi network during a first time period that one or more of the wireless devices 106 may communicate with the network device 102 via the WPAN. The wireless devices 106 may send a quantity (e.g., 2, 3, 5, 20, etc.) of communications (e.g., during a first time period, a second time period after the first time period, and so forth) without receiving a confirmation from the network device 102. The wireless devices 106 may not send a communication if the quantity of communications satisfies a threshold. The quantity of communications satisfying the threshold may indicate an error associated with the communication network. The wireless devices 106 may determine after the quantity of communications are sent that an error has occurred with the second wireless network such that the wireless devices 106 should not continue attempting to send communications via the second wireless network.
The network device 102 may determine the quantity of attempts that the wireless devices 106 may attempt to communicate with the network device 102 before the wireless devices 106 cease attempting to communicate with the network device 102. The network device 102 may determine the quantity of attempts to communicate based on pairing with the wireless devices 106. The network device 102 may determine to not modify the power level of the first wireless network (e.g., a Wi-Fi network) based on a quantity of communications received from a wireless device 106 via a second wireless network (e.g., a WPAN). That is, the network device 102 may determine to ignore one or more communications from the wireless device 106 by not reducing a power level of the first wireless network when the wireless device 106 may attempt to communicate with the network device 102. The network device 102 may dynamically determine to not modify the power level of the first wireless network based on a quantity of communications received from a wireless device 106 (e.g., via the second wireless network) and a usage of the first wireless network.
The network device 102 may utilize a data structure to determine the quantity of communications from a wireless device 106 that the network device 102 may ignore (e.g., not respond to). The network device 102 may determine a quantity of time periods that the network device 102 may not reduce the power level of the first wireless (e.g., a Wi-Fi network) based on the quantity of communications that the wireless device 106 may send before the wireless device 106 will halt communications. For example, the network device 102 may determine that a wireless device 106 will make three separate attempts to communicate with the network device 102 via the second wireless network (e.g., the WPAN) before halting communications. The network device 102 may determine that the network device 102 may ignore (e.g., not respond to) two communications from the wireless device 106 before the wireless device 106 stops communicating with the network device 102. The network device 102 may determine the time periods associated with the two communications from the wireless device 106. The network device 102 may determine, based on the time periods, a period of time the network device 102 may ignore (e.g., not respond to) communications from the wireless device 106. Accordingly, the network device 102 may not reduce power level of the first wireless network (e.g., the Wi-Fi network) during the time period that the network device 102 may ignore the wireless device 106 in order to ensure the best possible bandwidth for the first wireless network, while also preventing the wireless device 106 from determining that the wireless device 106 should stop communicating with the network device 102.
The network device 102 may concatenate one or more bands of the second wireless network. For example, the network device 102 may concatenate one or more bands of a WPAN. The bands of the second wireless network may be smaller bands as compared to bands of the first wireless network. For example, the bands of the WPAN may be smaller (e.g., 5 MHz bands) as compared to a Wi-Fi band (e.g., 20 MHz bands). Thus, the bands of the second wireless network may be difficult for the network device 102 to discern when communications on the second wireless network (e.g., the WPAN) and the first wireless network (e.g., the Wi-Fi network) are occurring concurrently. For example, the larger Wi-Fi bands may increase the interference with the WPAN bands if the two networks communicate concurrently as the Wi-Fi bands and WPAN bands utilize the same channel. The network device 102 may concatenate one or more bands of the second wireless network to create a new band to improve the ability for the network device 102 to receive communications from the wireless devices 106. The network device 102 may concatenate a predetermined quantity of bands of the second wireless network such that the concatenated band has approximately the same bandwidth as a band of the first wireless network. For example, the network device 102 may concatenate a predetermined quantity of bands of the WPAN such that the concatenated band has approximately the same bandwidth as a Wi-Fi band. Thus, the concatenated band of the second wireless network would have a similar bandwidth of the first wireless network band which would improve the Signal to Noise Ratio (SNR) of the concatenated second wireless network band compared to the non-concatenated second wireless network bands. By improving the SNR of the second wireless network communications, the network device 102 may improve the ability of the network device 102 to receive communications from the wireless devices 106.
The network device 102 may concatenate the one or more bands only when the network device 102 is not actively transmitting a communication on the second wireless network (e.g., the WPAN). That is, the network device 102 may concatenate the one or more bands of the second wireless network when listening for a communication from the wireless devices 106, but the network device 102 may utilize a single unconcatenated band of the second wireless network to transmit a communication to the wireless devices 106. By utilizing a single band of the second wireless network for sending a communication, the network device 102 may reduce the impact on the first wireless network (e.g., the Wi-Fi network).

That is, the communication software 206 may reduce the power provided to and/or output by the communication element 204a. The communication software 206 may reduce the power level of the network 202a based on a range (e.g., a distance from) of the wireless device 106 from the network device 102. That is, the further the wireless device 106 is from the network device 102, the communication software may increase the amount of power reduction of the network 202a to ensure the wireless device 106 is capable of communicating with the network device 102. The communication software 206 may modify a channel associated with the network 202a, and/or reduce a bandwidth of a channel associated with the network 202a.

Examples of such input devices comprise, but are not limited to, a keyboard, pointing device (e.g., a computer mouse, remote control), a microphone, a joystick, a scanner, tactile input devices such as gloves, and other body coverings, motion sensor, and the like These and other input devices may be connected to the one or more processors 703 via a human machine interface 702 that is coupled to the bus 713, but may be connected by other interface and bus structures, such as a parallel port, game port, an IEEE 1394 Port (also known as a Firewire port), a serial port, network adapter 708, and/or a universal serial bus (USB).
The display device 711 may also be connected to the bus 713 via an interface, such as the display adapter 709. It is contemplated that the computer 701 may have more than one display adapter 709 and the computer 701 may have more than one display device 711. The display device 711 may be a monitor, an LCD (Liquid Crystal Display), light emitting diode (LED) display, television, smart lens, smart glass, and/or a projector. In addition to the display device 711, other output peripheral devices may be components such as speakers (not shown) and a printer (not shown) which may be connected to the computer 701 via the Input/Output Interface 710. Any step and/or result of the methods may be output (or caused to be output) in any form to an output device. Such output may be any form of visual representation, including, but not limited to, textual, graphical, animation, audio, tactile, and the like. The display device 711 and computer 701 may be part of one device, or separate devices.
The computer 701 may operate in a networked environment using logical connections to one or more remote computing devices 714a,b,c. A remote computing device may be a personal computer, computing station (e.g., workstation), portable computer (e.g., laptop, mobile phone, tablet device), smart device (e.g., smartphone, smart watch, activity tracker, smart apparel, smart accessory), security and/or monitoring device, a server, a router, a network computer, a peer device, edge device, and so on. Logical connections between the computer 701 and a remote computing device 714a,b,c may be made via a network 715, such as a local area network (LAN) and/or a general wide area network (WAN). Such network connections may be through the network adapter 708. The network adapter 708 may be implemented in both wired and wireless environments. Such networking environments are conventional and commonplace in dwellings, offices, enterprise-wide computer networks, intranets, and the Internet.
Application programs and other executable program components such as the operating system 705 are shown herein as discrete blocks, although it is recognized that such programs and components reside at various times in different storage components of the computing device 701, and are executed by the one or more processors 703 of the computer. An implementation of the communication software 706 may be stored on or sent across some form of computer readable media. Any of the described methods may be performed by processor-executable instructions embodied on computer readable media.
While specific configurations have been described, it is not intended that the scope be limited to the particular configurations set forth, as the configurations herein are intended in all respects to be possible configurations rather than restrictive.
Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not actually recite an order to be followed by its steps or it is not otherwise specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is in no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including: matters of logic with respect to arrangement of steps or operational flow; plain meaning derived from grammatical organization or punctuation; the number or type of configurations described in the specification.
It will be apparent to those skilled in the art that various modifications and variations may be made without departing from the scope or spirit. Other configurations will be apparent to those skilled in the art from consideration of the specification and practice described herein. It is intended that the specification and described configurations be considered as exemplary only, with a true scope and spirit being indicated by the following claims.
