DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.


The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.


It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.


By the term “substantially” it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.


In various embodiment of the present disclosure, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., elements, such as numeric values, functions, operations, or components) but do not exclude presence of additional features.


In various embodiment of the present disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like, used herein may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included.


The terms, such as “first”, “second”, and the like, used herein may refer to various elements of various embodiments of the present disclosure, but do not limit the elements. For example, such terms do not limit the order and/or priority of the elements. Furthermore, such terms may be used to distinguish one element from another element. For example, “a first user device” and “a second user device” indicate different user devices. For example, without departing the scope of the present disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.


It will be understood that when an element (e.g., a first element) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element), it can be directly coupled with/to or connected to the other element or an intervening element (e.g., a third element) may be present. In contrast, when an element (e.g., the first element) is referred to as being “directly coupled with/to” or “directly connected to” another element (e.g., the second element), it should be understood that there are no intervening element (e.g., the third element).


According to the situation, the expression “configured to” used herein may be used as, for example, the expression “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”. The term “configured to” must not mean only “specifically designed to” be performed by hardware.

FIG. 4 is a configuration diagram of a Wi-Fi communication system according to various embodiments of the present disclosure.


Referring to FIG. 4, a Wi-Fi communication system 400 may include an electronic device 410, a first AP 420, a second AP 430, a dual AP 440, a BT device 450 connected with the electronic device 410 through BT, and a network 460. The Wi-Fi communication system 400 may be at least one of various embodiments of the present disclosure, and the present disclosure may not be restrictively interpreted through FIG. 4.


According to various embodiments of the present disclosure, the electronic device 410 may perform communication using a Wi-Fi network. The electronic device 410 may be connected to an AP which outputs a Wi-Fi signal to perform communication using the Wi-Fi network. A plurality of frequencies may be assigned to the Wi-Fi network. For example, a 5 GHz band as well as a 2.4 GHz band may be currently assigned to the Wi-Fi network. In addition, even though not used currently, various frequency bands may be assigned to the Wi-Fi network in the future. Note that various embodiments of the present disclosure do not disclaim electronic devices and APs which use frequency bands-to-be as well as the currently used 2.4 GHz and 5 GHz frequency bands.


According to various embodiments of the present disclosure, the electronic device 410 may receive Wi-Fi signals of APs around the electronic device 410 and may search for at least one or more of the first AP 420, the second AP 430, and the dual AP 440. The first AP 420 may be an AP supporting a first frequency (e.g., 2.4 GHz), and the second AP 430 may be an AP supporting a second frequency (e.g., 5 GHz). Furthermore, the dual AP 440 may an AP supporting both the first frequency and the second frequency. According to various embodiments of the present disclosure, the dual AP 440 may further support other frequencies as well as the first frequency and the second frequency.


According to various embodiments of the present disclosure, target objects that the electronic device 410 is capable of searching for may not be limited to the first AP 420, the second AP 430, and the dual AP 440 and may include other external electronic devices capable of performing communication. For example, the external electronic devices may include a device which supports the Wi-Fi Direct.


According to various embodiments of the present disclosure, as illustrated in FIG. 4, the electronic device 410 may display at least one or more APs found on a screen thereof. According to various embodiments of the present disclosure, the electronic device 410 may arrange the found at least one or more APs for each level of indicators (e.g., custom character) indicating Wi-Fi performance, such as Wi-Fi sensitivity, Wi-Fi signal strength (e.g., received signal strength indication (RSSI)), and the like. In contrast, the electronic device 410 may arrange the found at least one or more APs in an alphabetical order of names respectively set to the at least one or more APs found. Below, the Wi-Fi performance will be described using the Wi-Fi signal strength.


According to various embodiments of the present disclosure, the electronic device 410 may display a user interface (UI) for arranging the at least one or more APs found, on the screen. For example, the electronic device 410 may display a UI for arranging the found at least one or more APs in an order of Wi-Fi signal strength levels or in an alphabetical order of names thereof.


According to various embodiments of the present disclosure, the electronic device 410 may perform communication using one of the first frequency and the second frequency, based on a user setting. The user setting may include a first case where the first frequency is always used if the electronic device 410 connects with the dual AP 440, a second case where the second frequency is always used if the electronic device 410 connects with the dual AP 440, and a third case where the first frequency or the second frequency is selectively used according to a state of the electronic device 410. The electronic device 410 may display a UI for selecting the first case, the second case, and the third case. The electronic device 410 may receive a user input for selection of a case from a user and may use the selected case as the user setting. According to various embodiments of the present disclosure, the electronic device 410 may select one of the cases without a user input.


According to various embodiments of the present disclosure, for the third case, the electronic device 410 may determine whether to use either the first frequency or the second frequency. The electronic device 410 may compare a Wi-Fi signal strength level corresponding to the first frequency and a Wi-Fi signal strength level corresponding to the second frequency and may determine whether to use either the first frequency or the second frequency, based on the comparison result. For example, in the case where an indicator corresponding to the first frequency is, for example, “custom character” and an indicator corresponding to the second frequency is, for example, “custom character”, the electronic device 410 may establish a Wi-Fi network which uses the first frequency. In the case where a Wi-Fi signal strength level when the first frequency is used is the same that when the second frequency is used, the electronic device 410 may establish the Wi-Fi network using one, having a relatively excellent throughput, from among the first and second frequencies.


According to various embodiments of the present disclosure, the first frequency may be, for example, 2.4 GHz, and the second frequency may be, for example, 5 GHz. Under the same condition, the throughput of the 5 GHz Wi-Fi network may be higher than that of the 2.4 GHz Wi-Fi network. In addition, if the 5 GHz Wi-Fi network uses a channel bonding technique, the throughput of the 5 GHz Wi-Fi network may be much higher than that of the 2.4 GHz Wi-Fi network. Accordingly, in the case where a Wi-Fi signal strength level when the first frequency is used is the same that when the second frequency is used, the electronic device 410 may determine to use a band of which the throughput is relatively excellent, for example, a frequency of 5 GHz.


According to various embodiments of the present disclosure, the electronic device 410 may determine to use one of the first frequency and the second frequency, based on at least one or more of a state of charge (SOC), current consumption, and quantity of heat. For example, in the case where the state of charge is lower than a specific level, a frequency need be used such that battery consumption is reduced. Furthermore, the case that current consumption or quantity of heat is greater than or equal to a specific level may be viewed as a state where a processor of the electronic device 410 is overloaded. In this case, a frequency need be used such that current consumption is reduced.


According to various embodiments of the present disclosure, current consumption when Wi-Fi communication is performed using 2.4 GHz may be smaller than that when Wi-Fi communication is performed using 5 GHz. Accordingly, if the state of charge is lower than a specific level or the current consumption or quantity of heat is greater than or equal to a specific level, the electronic device 410 may determine to perform Wi-Fi communication using a frequency of a relatively low band.


According to various embodiments of the present disclosure, the electronic device 410 may determine to perform Wi-Fi communication in which one of the first frequency and the second frequency is used thereon, based on whether the electronic device 410 performs communication through another network in which the first frequency or the second frequency is used. Since a currently used BT network uses a 2.4 GHz band, mutual interference may occur if the 2.4 GHz Wi-Fi communication and the BT communication are performed at the same time, thereby lowering performance about each of the 2.4 GHz Wi-Fi communication and the BT communication. For example, in the case where the electronic device 410 is paired with the BT device 450, for example, a 2.4 GHz BT speaker, the electronic device 410 may determine to perform the 5 GHz Wi-Fi communication.


According to various embodiments of the present disclosure, the electronic device 410 may hand the first frequency or the second frequency, which is determined as being used as a Wi-Fi communication frequency band, over to the second frequency or the first frequency. The frequency handover may be performed based on one or more of factors for determining the first frequency or the second frequency. For example, the electronic device 410 may compare a Wi-Fi signal strength level corresponding to the first frequency and a Wi-Fi signal strength level corresponding to the second frequency and may perform the frequency handover based on the comparison result. In the case where as a distance from the dual AP 440 increases a Wi-Fi signal strength level of the first frequency becomes relatively good compared to the second frequency, the electronic device 410 using the second frequency may change the second frequency into the first frequency. In general, a straight characteristic of a high frequency may be stronger than that of a low frequency, while a diffraction characteristic of the high frequency may be weaker than that of the low frequency. For this reason, in the case where a wall is placed between the electronic device 410 and the dual AP 440, a Wi-Fi signal strength level about the high frequency may become relatively weak. For example, in the case where the electronic device 410 using the high frequency moves into a room from a living room in which the dual AP 440 is located, the electronic device 410 may change the high frequency, which is being used, into the low frequency.


According to an embodiment of the present disclosure, a Wi-Fi signal strength level corresponding to the first frequency may become lower than that corresponding to the second frequency while the electronic device 410 establishes a Wi-Fi network using the first frequency. In this case, the electronic device 410 may change the first frequency (e.g., 2.4 GHz), which is being used, into the second frequency (e.g., 5 GHz) of a higher band of which the throughput is relatively excellent.


According to an embodiment of the present disclosure, the electronic device 410 may change a frequency based on at least one or more of a state of charge, current consumption, and quantity of heat thereof. For example, in the case where the state of charge of the electronic device 410 becomes lower than a specific level with the lapse of time, the electronic device 410 which uses a frequency causing great current consumption may change a frequency, which is being used, into a frequency causing small current consumption. In contrast, in the case where the electronic device 410 is connected to power or in the case where the state of charge of the electronic device 410 increases over a level, the electronic device 410 which uses a frequency causing small current consumption may change a frequency, which is being used, into a frequency causing great current consumption.


According to an embodiment of the present disclosure, in the case where the current consumption or the quantity of heat of the electronic device 410 is over a level due to execution of at least one or more applications or activation of a sensor, and the like, the electronic device 410 which uses a frequency causing great current consumption may change a frequency, which is being used, into a frequency causing small current consumption.


Furthermore, the electronic device 410 may perform frequency handover based on whether the electronic device 410 is performing communication through another network in which the first frequency or the second frequency is used. For example, in the case where the electronic device 410 which is using 2.4 GHz uses 2.4 GHz BT network, the electronic device 410 may change 2.4 GHz, which is being used, into 5 GHz. In addition, in the case where the 2.4 GHz BT network that the electronic device 410 is using is inactivated, the electronic device 410 may change 5 GHz, which is being used, into 2.4 GHz.


According to an embodiment of the present disclosure, in the case where the dual AP 440 is found, the electronic device 410 may determine whether to display the dual AP 440 as one AP or to whether to display an AP about the first frequency and an AP about the second frequency on the screen independently. Displaying of the dual AP 440 may be determined according to a user input which is provided through a UI displayed on the screen.


According to an embodiment of the present disclosure, the first AP 420, the second AP 430, and the dual AP 440 may provide Wi-Fi signals to allow the electronic device 410 to use the Wi-Fi network. The first AP 420, the second AP 430, and the dual AP 440 may be located at various spots, such as a home, a company, a restaurant, and the like. At least one of the first AP 420, the second AP 430, and the dual AP 440 may be an AP which operates through a hotspot function on another electronic device (not illustrated).


According to an embodiment of the present disclosure, an embodiment of the present disclosure is exemplified in FIG. 4 as each of the first AP 420, the second AP 430, and the dual AP 440 has a dual antenna. However, the scope and spirit of the present disclosure may not be limited thereto. For example, the first AP 420 may use one antenna, and the second AP 430 may use three antennas.


In FIG. 4, an embodiment of the present disclosure is exemplified as the BT device 450 is a BT speaker. However, the BT device 450 may be a variety of electronic devices which are able to be paired with the electronic device 410 using a BT network. For example, the BT device 450 may be a BT mouse, a BT keyboard, and the like. Furthermore, the BT device 450 may be an electronic device, such as a smartphone, and the like.


The network 460 (e.g., the network 162 illustrated in FIG. 1) may respectively connect the electronic device 410, the he first AP 420, the second AP 430, and the dual AP 440 included in the Wi-Fi communication system 400. In this case, the network 460 may indicate a connection structure in which information exchange between nodes, such as electronic devices and servers, is possible. The network 460 may include, but not limited to, Wi-Fi, BT, Bluetooth low energy (BLE), NFC, GPS, or cellular communication (e.g., third generation (3G), LTE, LTE-A, CDMA, WCDMA, UMTS, WiBro, and GSM), and the like.


A service which searches for at least one or more APs and performs communication using one of the found APs may be provided through an application installed on the electronic device 410. Here, the application may indicate an application program and may include, for example, an app executed on the electronic device 410.



FIG. 5 is a configuration diagram of an electronic device according to various embodiments of the present disclosure.


Referring to FIG. 5, the electronic device 410 may include an AP search circuit 510, a display circuit 520, a user input receiving circuit 530, a communication circuit 540, a processor 550, a memory 560, and the like. The electronic device 410 illustrated in FIG. 4 may correspond to one or more of various embodiments of the present disclosure. Various modifications or changes about the electronic device 410 may be made based on components illustrated in FIG. 5. For example, the electronic device 410 may further include a user interface which receives any instruction or information, for example, a user input from a user. In this case, the user interface may be an input device, such as a keyboard, a mouse, and the like, or may be a GUI expressed on an image display device.


The AP search circuit 510 may search for at least one or more APs which are connectable through the communication circuit 540. The APs may include the first AP 420 supporting a first frequency, the second AP 430 supporting a second frequency, and the dual AP 440 supporting both the first frequency and the second frequency. Below, it may be assumed that the first frequency is 2.4 GHz and the second frequency is 5 GHz. As described above, an object that the electronic device 410 performs communication with may not be limited to an AP. For example, the object may be comprehensively interpreted as being an external electronic device including an AP, and the like. Accordingly, the AP search circuit 510 may search for a smartphone and the like using the Wi-Fi direct, and the like, as well as an AP.


The display circuit 520 may display information associated with at least one external electronic device connectable through the communication circuit 540, on a screen. For example, the display circuit 520 may display at least one or more APs found by the AP search circuit 510, on a screen of the electronic device 410. The display circuit 520 may include, for example, a configuration which is at least the same as or similar to the display 160 illustrated in FIG. 1. Furthermore, an operation of the display circuit 520 may be performed based on an instruction or a signal received from the processor 550.


According to various embodiments of the present disclosure, the display circuit 520 may provide a UI which is used to determine whether to display the dual AP 440 as one AP or whether to display an AP about 2.4 GHz and an AP about 5 GHz independently. In addition, as selected through the UI, the display circuit 520 may display the dual AP 440 as one AP or may display an AP about 2.4 GHz and an AP about 5 GHz independently.


The displayed at least one or more APs may be arranged through various conditions. For example, the at least one or more APs may be arranged for a Wi-Fi sensitivity or for a Wi-Fi signal strength level, such as Wi-Fi signal strength, and the like. Alternatively, the at least one or more APs may be arranged based on an alphabetical order of names assigned to the at least one or more APs. Arrangement of at least one or more APs will be described with reference to FIG. 6.


The user input receiving circuit 530 may receive a user input selecting one of at least one or more APs displayed on the screen. The user input receiving circuit 530 may include, for example, a configuration which is at least the same as or similar to the touch panel 252 illustrated in FIG. 2. According to various embodiments of the present disclosure, it may be assumed that the user input receiving circuit 530 receives a user input selecting the dual AP 440 which supports both 2.4 GHz and 5 GHz.


The communication circuit 540 may perform communication, in which one of 2.4 GHz and 5 GHz is used, based on a user setting, as a response to the user input received through the user input receiving circuit 530.


The communication circuit 540 may include a first communication circuit and a second communication circuit. The first communication circuit may perform wireless communication with an external electronic device, based on a first communication protocol (e.g., an 802.11 protocol) in which wireless communication is possible using the first frequency (e.g., 2.4 GHz) and/or the second frequency (e.g., 5 GHz). The second communication circuit may perform wireless communication with an external electronic device, based on a second communication protocol (e.g., a Bluetooth protocol) in which wireless communication is possible in a frequency domain the same as or similar to the first frequency.


The processor 550 may include, for example, a configuration which is at least the same as or similar to the processor 120 illustrated in FIG. 1.


The processor 550 may acquire information associated with at least one of a state or an operation of the electronic device 410. The state or operation of the electronic device 410 may include at least one of a power state, a temperature, a state of charge (SOC), a battery charging operation, current consumption, and the quantity of heat. Furthermore, the state or operation of the electronic device 410 that the processor 550 collects may include information about whether the second communication circuit is operating.


The processor 550 may select a frequency, which the communication circuit 540, for example, the first communication circuit will use, from among the first frequency (e.g., 2.4 GHz) and the second frequency (e.g., 5 GHz). The processor 550 may allow the first communication circuit to perform wireless communication selectively using one of 2.4 GHz and 5 GHz, based on at least a part of information associated with at least one of the state or the operation of the electronic device 410. In this case, the processor 550 may allow the first communication circuit to perform wireless communication selectively using one of 2.4 GHz or 5 GHz.


Similarly, in the case where the first communication circuit uses a plurality of frequencies variously as well as the first and second frequencies, the processor 550 may allow the first communication circuit to dynamically perform wireless communication selectively using at least one of the plurality of frequencies, based on at least a part of information associated with at least one of the state or the operation of the electronic device 410 previously collected.


The processor 550 according to various embodiments of the present disclosure may compare a Wi-Fi signal strength level corresponding to the 2.4 GHz and a Wi-Fi signal strength level corresponding to 5 GHz and may determine to use one of 2.4 GHz or 5 GHz on the communication circuit 540. If a Wi-Fi signal strength level when 2.4 GHz is used is the same as that when 5 GHz is used, the processor 550 may determine to use 5 GHz of a high band, of which the throughput is excellent, on the communication circuit 540.


Furthermore, the processor 550 may determine to use one of 2.4 GHz or 5 GHz on the communication circuit 540, based on at least one or more of a state of charge, current consumption, and the quantity of heat. For example, a frequency of a 2.4 GHz Wi-Fi network may be lower than that of a 5 GHz Wi-Fi network. In this case, since signal attenuation of the 2.4 GHz Wi-Fi network is smaller than that of the 5 GHz Wi-Fi network, current consumption of the 2.4 GHz Wi-Fi network may be smaller than that of the 5 GHz Wi-Fi network. Accordingly, in the case where the state of charge is lower than a specific level, the processor 550 may determine to use 2.4 GHz on the communication circuit 540, and thus, the power of the electronic device 410 may be maintained relatively long. Furthermore, in the case where current consumption or the quantity of heat is greater than or equal to a specific level, the processor 550 may select 2.4 GHz to prevent sudden consumption of the battery and to reduce the quantity of heat or a specific absorption rate (SAR) value.


The processor 550 according to various embodiments of the present disclosure may determine to use one of 2.4 GHz or 5 GHz on the communication circuit 540, based on whether the communication circuit 540 is using 2.4 GHz or 5 GHz. For example, since the BT network uses 2.4 GHz, the processor 550 may determine to use 5 GHz on the communication circuit 540 such that interference with the BT network does not occur when the communication circuit 540 is using the BT network.


According to various embodiments of the present disclosure, the processor 550 may switch the 2.4 GHz Wi-Fi network or the 5 GHz Wi-Fi network, which is determined as being used on the communication circuit 540, into the 5 GHz Wi-Fi network or the 2.4 GHz Wi-Fi network and may change a usable frequency. A reference which is used for the processor 550 to change a usable frequency may correspond to a reference for determining a frequency that the communication circuit 540 previously intents to use.


For example, the processor 550 may compare a Wi-Fi signal strength level corresponding to 2.4 GHz and a Wi-Fi signal strength level corresponding to 5 GHz and may perform frequency handover so as to use Wi-Fi of which the signal strength is better. For example, in the case where a Wi-Fi signal strength level corresponding to 5 GHz is lower than that corresponding to 2.4 GHz due to location movement, and the like of the electronic device 410 using 5 GHz, the processor 550 may change a frequency such that the communication circuit 540 uses 2.4 GHz. In contrast, in the case where a Wi-Fi signal strength level corresponding to 2.4 GHz is lower than that corresponding to 5 GHz due to location movement, and the like, of the electronic device 410 using 2.4 GHz, the processor 550 may change a frequency such that the communication circuit 540 uses 5 GHz of a relatively high band of which the throughput is relatively excellent.
