Cellular communication devices use various network radio access technologies to communicate wirelessly with geographically distributed base stations and/or access points. Long-Term Evolution (LTE) is an example of a widely implemented radio access technology, which is used within 4th-Generation (4G) communication systems. New Radio (NR) is a newer radio access technology that is used in 5th-Generation (5G) communication systems. Standards for LTE and NR radio access technologies have been developed by the 3rd-Generation Partnership Project (3GPP) for use within cellular communication networks by wireless communication carriers.
Existing 4G networks use relatively low radio frequencies, such as frequencies in bands below 6 GHz. 5G networks are able to use an extended range of frequency bands compared to 4G networks, such as higher frequency bands in in the range of 6-100 GHz. Radio communications using the higher frequency 5G bands can support higher data speeds, but also have disadvantages compared to the lower frequency bands. Specifically, radio signals in the higher frequencies have shorter range and are more easily blocked by physical objects. Accordingly, the ability for a communication device to communicate using higher-frequency 5G bands may be sporadic as the device is physically moved.
The detailed description is described with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different figures indicates similar or identical components or features.
Techniques for determining radio frequency (RF) resources to utilize in a mesh network in order to optimize the functioning of the mesh network are discussed herein. RF resources may include, for example, licensed bands or unlicensed bands. In some examples, a centralized database may monitor radio links between access points and UEs that are connected to them as well as the links between access points that make up the mesh network and may receive conditions data from the access points in order to determine the RF resources that should be used in order to optimize the mesh network. Conditions data may include, for example, signal level, signal quality, or packet loss.
As the use and functionality of user equipment (UE) increases, so does the overall bandwidth demands in a communications network. Additionally, with mm-wave RF deployments, which may be used in some 5G communication systems, signal propagation is effective over shorter and shorter distances, which may lead to holes in wireless coverage. A plurality of access points may be located throughout an environment to address these increased bandwidth demands and/or “holes” in coverage by providing line-of-sight signals to an environment. Each access point within a mesh network may communicate with one another and/or a core network via backhaul links, which may comprise wired or wireless connections. These backhaul links may be monitored by a centralized database described herein and be used to determine a type of RF resource which each access point should utilize in order to optimize the mesh network, thereby providing better network coverage to the UE and reducing strain on the network.
In particular, a centralized database may be stored at a telecommunications device, such as a core network server or a base station. The centralized database may monitor the links between the access points and the UEs connected to them as well as the links used to communicate between the access points that make up a mesh network. In some cases, the access points may store an agent that reports conditions data to the centralized database. For example, the agent stored at an access point may monitor conditions data, such as weather data, signal level, a signal quality, a packet loss rate, interference, an uplink rate, or a downlink rate, and report the conditions data to the centralized database. In some cases, the conditions data may include a location of the access point or nearby access points such that the centralized database may determine a distance between access points. For example, two access points having a greater distance between one another may require a RF with a lower frequency and further range in order to communicate than two access points that are closer in distance that may communicate using a RF with a greater frequency and shorter range. Once the centralized database has received the conditions data, a machine learning algorithm may be utilized to determine a RF resource to be utilized for an individual access point or a group of access points that make up the mesh network. In some cases, the RF resources may be determined based on a determined potential throughput calculated based on the conditions data.
In some cases, the RF resources may include licensed or unlicensed spectrum or a combination of licensed and unlicensed. For example, unlicensed spectrum may include a number of unlicensed RF bands, such as Wi-Fi, Bluetooth, etc., each of which may have different characteristics that may affect the mesh network in a different way. Similarly, licensed spectrum may include a number of licensed RF bands, such as RF signals according to 3rd Generation Partnership Project (3GPP) protocols, Universal Mobile Telecommunications System (UMTS) protocols, Long Term Evolution (LTE) protocols, Fifth Generation (5G) protocols, etc., that each include different characteristics that affect the mesh network in a different way. Each access point in the mesh network may support both licensed RF bands and unlicensed RF bands and each access point may be configured to receive an instruction from the centralized database to utilize a specific RF band based on the conditions data that was provided to the centralized database. In some cases, different access points may receive instructions to operate on different bands such that the mesh network utilizes both licensed and unlicensed spectrum as well as different bands within each of the licensed and unlicensed spectrum.
The systems, devices, and techniques described herein can improve a functioning of a network by optimizing communications in a mesh network to improve bandwidth, reduce interference, and the like, to provide wireless resources to various UEs. For example, the systems, devices, and techniques can determine weather data, distances between access points, UE distributions, communication protocols beings used by access points, and the like, in order to determine if these factors are causing or are otherwise affected by interference between the access points that make up the mesh network. The systems, devices, and techniques discussed herein provide a distributed framework for network analysis, which provides the ability to modify individual access points and their associated communication links automatically and remotely. Moreover, by constantly monitoring the network and modifying the access points and their associated communication links, the network may automatically and remotely send commands to the access points to adjust (e.g., increase or decrease) transmission power or protocols, for example. These and other improvements to the functioning of a computer and network are discussed herein.
The systems, devices, and techniques described herein can be implemented in a number of ways. Example implementations are provided below with reference to the following figures.
In a configuration, the UE 104 may comprise any appropriate device, e.g., a stationary device or a portable electronic device, for communicating over a wireless communication network. Such devices include mobile telephones, cellular telephones, internet protocol (IP) telephones, mobile computers, Personal Digital Assistants (PDAs), radio frequency devices, handheld computers, laptop computers, tablet computers, palmtops, pagers, devices configured as IoT devices, IoT sensors that include cameras, integrated devices combining one or more of the preceding devices, and/or the like. As such, UE 104 may range widely in terms of capabilities and features. For example, in a configuration, the UE 104 may have a numeric keypad, a capability to display only a few lines of text and be configured to interoperate with only Global System for Mobile Communications (GSM) networks. However, in another configuration, the UE 104 (e.g., a smart phone) may have a touch-sensitive screen, a stylus, an embedded Global Positioning System (GPS) receiver, and a relatively high-resolution display, and be configured to interoperate with multiple types of networks. The UE 104 may also comprise a SIM-less device (i.e., a UE that does not contain a functional subscriber identity module (“SIM”)), a roaming UE (i.e., a UE operating outside of their home access network), and/or mobile software applications.
In a configuration, the access points 102 may communicate voice traffic and/or data traffic with one or more UEs 104 using RF signals. The access points 102 may communicate with the UE 104 using one or more appropriate wireless communication protocols or standards. For example, the access points 102 may communicate with the UE 104 using one or more standards, including but not limited to GSM, Time Division Multiple Access (TDMA), Universal Mobile Telecommunications System (UMTS), Evolution-Data Optimized (EVDO), Long Term Evolution (LTE), Fifth Generation (5G), Generic Access Network (GAN), Unlicensed Mobile Access (UMA), Code Division Multiple Access (CDMA) protocols (including IS-95, IS-2000, and IS-856 protocols), Advanced LTE or LTE+, Orthogonal Frequency Division Multiple Access (OFDM), General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Advanced Mobile Phone System (AMPS), Wi-Fi protocols (including IEEE 802.11 protocols), WiMAX protocols (including IEEE 802.16e-2005 and IEEE 802.16m protocols), High Speed Packet Access (HSPA) (including High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSDPA)), Ultra Mobile Broadband (UMB), and/or the like.
In configurations, the core network 108 may support packet-switched or circuit-switched connections and may include a number of network components. Such components may include a home location register (HLR) or HSS for storing user and components may also include an application server(s), such as a telephony application server (TAS) or rich communication service (RCS) server. Further, the core network 108 may include an account information server (AIS), which may provide network identities, contact addresses, credentials, and other information to the UEs 104.
In addition to or instead of the configuration above, in some examples the core network 108 may include 4G core network comprising a Mobility Management Entity (MME), a Serving Gateway (SGW), a Packet Data Network (PDN) Gateway (PGW), a Home Subscriber Server (HSS), an Access Network Discovery and Selection Function (ANDSF), an evolved Packet Data Gateway (ePDG), a Data Network (DN), and the like.
In addition to or instead of the configuration above, in some examples the core network 108 can include a 5G core network comprising any of an Access and Mobility Management Function (AMF), a Session Management Function (SMF), a Policy Control Function (PCF), an Application Function (AF), an Authentication Server Function (AUSF), a Network Slice Selection Function (NSSF), a Unified Data Management (UDM), a Network Exposure Function (NEF), a Network Repository Function (NRF), a User Plane Function (UPF), a data network (DN), and the like.
In addition, the core network 108 may be implemented on a single computing device. Such computing devices may each be or include a server or server farm, multiple, distributed server farms, a mainframe, a work station, a PC, a laptop computer, a tablet computer, an embedded system, or any other sort of device or devices. In one implementation, the computing device(s) represent a plurality of computing devices working in communication, such as a cloud-computing network of nodes.
In configurations, the core network 108 may include a centralized database that may monitor links 110(1), 110(2), 110(3), 110(Y) used to communicate between the access points 102 that make up a mesh network 112. In some examples, the links 110(1)-110(Y) include communication channels. In some cases, the access points 102 may store an agent that reports conditions data to the centralized database stored at the core network 108. For example, the agent stored at the access point 102 may monitor conditions data, such as weather data (e.g., temperature, humidity, indications of rain, etc.), signal level and/or a signal quality (e.g., SINR/SNR, RSRP, RSRQ, RSSI, etc.), a packet loss rate, interference, an uplink rate, or a downlink rate, load information, and the like, and may report the conditions data to the centralized database at the core network 108. In some cases, the conditions data may include a location of the access point 102 or nearby access points 102(1)-102(X) such that the centralized database at the core network 108 may determine a distance between access points 102. For example, access points 102(1) and 102(3) may have a greater distance between one another and may use a RF with a lower frequency and further range in order to communicate via the link 110(Y) than access points 102(1) and 102(2) that are closer in distance and may communicate using a RF with a greater frequency and shorter range via link 110(1).
In some cases, the centralized database may receive conditions data from a third-party other than the access points 102. For example, the centralized database may receive environmental conditions from a third-party, such as a weather service. In some cases, the conditions data may include self-organized network (SON) data collected by the access points 102. In some examples, the centralized database may receive connection information indicating frequency resources and/or protocols being used by access points 102 of the mesh network 112 at various instants of time. Once the centralized database has received the conditions data and/or connection information, a machine learning algorithm may be utilized to determine a potential throughput for the mesh network 112 and/or an individual access point 102 if a RF resource is utilized for an individual access point 102 or a group of access points 102(1)-102(X) that make up the mesh network 112. For example, the RF resource may be determined based on a determined potential throughput calculated based on the conditions data.
In some examples, the machine learning algorithm may include multiple models that may be updated based on historical data. The machine learning algorithm may include heuristics, IF-THEN statements, and the like. In some examples, a machine learning algorithm can include, but is not limited to, one or more of: neural network(s), convolutional neural network(s), recurrent neural network(s), linear regression algorithm(s), logistic regression algorithm(s), classification and regression tree algorithm(s), Naïve Bayes algorithm(s), K-nearest neighbors algorithm(s), learning vector quantization algorithm(s), support vector machine(s), bagging and random forest algorithm(s), boosting and Adaboost algorithm(s), and the like.
In some examples, the access node 102(1) of the mesh network 112 may operate using a first protocol to communicate. The centralized database may receive data, such as conditions data, connection information, weather condition data, and/or load information, from any or all of the access nodes 102(1)-102(X) that make up the mesh network 112 and/or a third party. The machine learning algorithm stored at the centralized database may determine if, based on the received data, whether the links 110(1)-110(Y) should be modified to increase robustness (e.g., if weather is causing interference, if two close access points are using the same resources and causing interference, and the like), increase bandwidth (e.g., based on load), etc. In some examples, the machine learning algorithm may be configured to consider other factors when determining if the links 110(1)-110(Y) should be modified, such as a distance between the access points 102(1)-102(X), a type of traffic being utilized via access points 102(1)-102(X), a determined bandwidth being utilized via the access points 102(1)-102(X), etc.
In some cases, the RF resource may include licensed spectrum or unlicensed spectrum. For example, unlicensed spectrum may include a number of unlicensed RF bands, such as Wi-Fi, Bluetooth, etc., each of which may have different characteristics that may affect the mesh network in a different way. Similarly, licensed spectrum may include a number of licensed RF bands, such as RF signals according to 3rd Generation Partnership Project (3GPP) protocols, Universal Mobile Telecommunications System (UMTS) protocols, Long Term Evolution (LTE) protocols, Fifth Generation (5G) protocols, etc., that each include different characteristics that affect the mesh network 112 in a different way. In some cases, the centralized database may determine that different access points 102 should receive instructions to operate on different bands such that the mesh network 112 utilizes both licensed and unlicensed spectrum as well as different bands within each of the licensed and unlicensed spectrum. Each access points 102(1)-102(X) in the mesh network 112 may support both licensed RF bands and unlicensed RF bands and each access point 102(1)-102(X) may be configured to receive an instruction from the centralized database of the core network 108 to utilize a specific RF resource (e.g., a specific RF band) based on the conditions data that was provided to the centralized database of the core network 108. The RF resource may be any of, or any combination of, single unlicensed carrier, multiple aggregated unlicensed carriers, single licensed carrier, or multiple aggregated licensed carriers.
In configurations, the base station 214 may be associated with any one of a macrocell, microcell, a picocell, or a femtocell for providing radio access to the UEs 204. One example macrocell is a node in an evolved UMTS Terrestrial Radio Access Network (E-UTRAN) of an LTE system. The E-UTRAN includes an evolved NodeB (eNodeB or eNB). In one example, an eNB functions similarly to a base transceiver station in a GSM network. The E-UTRAN facilitates communication between the UEs 204 and the core network 208. In an example, an eNB is connected to the core network 208 and communicates directly with UEs 204. In some examples, the macrocell may include a gNodeB of a Fifth Generation (5G) cellular network.
In configurations, the base station 214 may include a centralized database that may monitor links 210(1), 210(2), 210(3), 210(M) used to communicate between the access points 202 that make up the mesh network 212. In some cases, the access points 202 may store an agent that reports conditions data to the centralized database stored at the base station 214. For example, the agent stored at the access point 202 may monitor conditions data, such as weather data (e.g., temperature, humidity, indications of rain, etc.), signal level and/or a signal quality (e.g., SINR/SNR, RSRP, RSRQ, RSSI, etc.), a packet loss rate, interference, an uplink rate, or a downlink rate, load information, and the like, and may report the conditions data to the centralized database at the base station 214. In some cases, the conditions data may include a location of the access point 202 or nearby access points 202(1)-202(Z) such that the centralized database at the base station 214 may determine a distance between access points 102. For example, access points 202(1) and 202(3) may have a greater distance between one another and may use a RF with a lower frequency and further range in order to communicate via the link 210(M) than access points 202(1) and 202(2) that are closer in distance and may communicate using a RF with a greater frequency and shorter range via link 210(1).
In some cases, the centralized database may receive conditions data from a third-party other than the access points 202. For example, the centralized database may receive environmental conditions from a third-party, such as a weather service. In some cases, the conditions data may include self-organized network (SON) data collected by the access points 202. In some examples, the centralized database may receive connection information indicating frequency resources and/or protocols being used by access points 202 of the mesh network 212 at various instants of time. Once the centralized database of the base station 214 has received the conditions data and/or connection information, a machine learning algorithm may be utilized to determine a RF resource to be utilized for an individual access point 202 or a group of access points 202(1)-202(Z) that make up the mesh network 212. In some cases, the RF resource may be determined based on a determined potential throughput calculated based on the conditions data. In some cases, the RF resource may include licensed or unlicensed spectrum. For example, unlicensed spectrum may include a number of unlicensed RF bands, such as Wi-Fi, Bluetooth, etc., each of which may have different characteristics that may affect the mesh network in a different way.
Similarly, licensed spectrum may include a number of licensed RF bands, such as RF signals according to 3rd Generation Partnership Project (3GPP) protocols, Universal Mobile Telecommunications System (UMTS) protocols, Long Term Evolution (LTE) protocols, Fifth Generation (5G) protocols, etc., that each include different characteristics that affect the mesh network 212 in a different way. Each access point 202(1)-202(Z) in the mesh network 212 may support both licensed RF bands and unlicensed RF bands and each access point 202(1)-202(Z) may be configured to receive an instruction from the centralized database of the base station 214 to utilize a specific RF band, or a combination of RF bands, based on the conditions data that was provided to the centralized database of the base station 214.
In some cases, the centralized database may determine that different access points 202 should receive instructions to operate on different bands such that the mesh network 212 utilizes both licensed and unlicensed spectrum as well as different bands within each of the licensed and unlicensed spectrum. The network 200 may include any of the devices and communication protocols discussed above with regard to network 100.
In various implementations, system memory 302 is volatile (such as RAM), non-volatile (such as ROM, flash memory, etc.), or some combination of the two. The communication component 306 may communicate with any of the access points 102, access points 202, and/or the base station 214 in order to receive conditions data related to the mesh network 112 and/or mesh network 212. The conditions data may include any type of information related to the network 100 and/or network 200. For example, the conditions data may include weather data, signal level, a signal quality, a packet loss rate, interference, an uplink rate, or a downlink rate. In some cases, the conditions data may include a location of the access points 102 and/or the access points 202 such that the centralized database 304 may determine a distance between access points 102 or access points 202. In some cases, the conditions data may include a distance that an access point 102 (e.g., access point 102(1) is from another access point 102 (e.g., access point 102(2), 102(3), and/or 102(X)).
The agent component 308 may store the conditions data received via the communication component 306 as well as any identifying information related to the access points 102 and/or the access points 202. For example, the agent component may determine which conditions data was received from which agent stored on access point 102 and/or access point 202 and may associate the conditions data with the identified agent of the access point when the conditions data is stored. In some cases, when the conditions data is received in a transmission, the transmission may also include identifying information associated with the specific access point 102 and/or the access points 202 that sent the transmission.
In some cases, the agent component 308 may receive location information associated with the access points 102 and/or the access points 202 and may store the location information along with the conditions data associated with the individual access points 102 and/or the access points 202. In some cases, the location information may be included in the conditions data and the agent component 308 may determine a distance between the access points based on the location information. In some cases, the access points 102 and/or the access points 202 may provide a distance to a nearest neighboring access point instead of or in addition to the location information.
The machine learning component 310 may utilize the conditions data, the location information, and/or the distance information to determine a RF resource to be utilized for an individual access point 102 and/or 202 or a group of access points 102(1)-102(X) and/or 202(1)-202(Z) that make up the mesh network 112 and the mesh network 212, respectively. In some cases, the RF resource may be determined based on a determined potential throughput calculated based on the conditions data, the location information, and/or the distance information. The machine learning algorithm may include heuristics, IF-THEN statements, Neural Networks, and the like. In some cases, the RF resource may include licensed and/or unlicensed spectrum.
For example, unlicensed spectrum may include a number of unlicensed RF bands, such as Wi-Fi, Bluetooth, etc., each of which may have different characteristics that may affect the mesh network 112 and/or the mesh network 212 in a different way. Similarly, licensed spectrum may include a number of licensed RF bands, such as RF signals according to 3rd Generation Partnership Project (3GPP) protocols, Universal Mobile Telecommunications System (UMTS) protocols, Long Term Evolution (LTE) protocols, Fifth Generation (5G) protocols, etc., that each include different characteristics that affect the mesh network 112 and/or the mesh network 212 in a different way.
In some cases, the machine learning component 310 may determine that different access points 102(1)-102(X) and/or 202(1)-202(Z) should receive instructions to operate on different bands such that the mesh network 112 and 212 utilizes both licensed and unlicensed spectrum as well as different bands within each of the licensed and unlicensed spectrum. Once the machine learning component 310 has determined the RF resource for each access points 102(1)-102(X) and/or 202(1)-202(Z) in the mesh networks 112 and 212 to utilize, the communication component 306 may send a signal to the access points 102(1)-102(X) and/or 202(1)-202(Z) instructing them to communicate using the determined RF resource.

In some implementations, the transceivers 518 include any sort of transceivers known in the art. For example, transceivers 518 may include a radio transceiver that performs the function of transmitting and receiving radio frequency communications via an antenna. The transceivers 518 may facilitate wireless connectivity between the UE 500 and other devices. In addition, the transceivers 518 may also include a wireless communication transceiver and a near field antenna for communicating over unlicensed wireless IP networks, such as local wireless data networks and personal area networks (e.g., Bluetooth or near field communication (NFC) networks). Further, the transceivers 518 may include wired communication components, such as an Ethernet port, that connect the UE 500 in a wired fashion to other devices.

Output devices 520 also include ports for one or more peripheral devices, such as headphones, peripheral speakers, or a peripheral display.
In various implementations, input devices 522 include any sort of input devices known in the art. For example, input devices 522 may include a camera, a microphone, a keyboard/keypad, or a touch-sensitive display. A keyboard/keypad may be a push button numeric dialing pad (such as on a typical telecommunication device), a multi-key keyboard (such as a conventional QWERTY keyboard), or one or more other types of keys or buttons, and may also include a joystick-like controller and/or designated navigation buttons, or the like.
As shown in
For example, at operation 602, a computing device can receive conditions data from at least one access point. For example, the core network 108 or the base station 214 may include a centralized database that may monitor links 110(1), 110(2), 110(3), 110(Y) used to communicate between the access points 102 that make up a mesh network 112. In some cases, the access points 102 may store an agent that reports conditions data to the centralized database stored at the core network 108. For example, the agent stored at the access point 102 may monitor conditions data, such as weather data, signal level, a signal quality, a packet loss rate, interference, an uplink rate, or a downlink rate, and report the conditions data to the centralized database at the core network 108. In some cases, the conditions data may include a location of the access point 102 or nearby access points 102(1)-102(X) such that the centralized database at the core network 108 may determine a distance between access points 102.
For example, access points 102(1) and 102(3) may have a greater distance between one another and may require a RF with a lower frequency and further range in order to communicate via the link 110(Y) than access points 102(1) and 102(2) that are closer in distance and may communicate using a RF with a greater frequency and shorter range via link 110(1).
In some cases, the centralized database may receive conditions data from a third-party other than the access points 102. For example, the centralized database may receive environmental conditions from a third-party, such as a weather service. In some cases, the conditions data may include self-organized network (SON) data collected by the access points 102.
At operation 604, a computing device can determine, based at least in part on the conditions data, a potential throughput for at least one backhaul link associated with the at least one access point. For example, once the centralized database has received the conditions data, a machine learning algorithm may be utilized to determine a potential throughput for the mesh network 112 and/or an individual access point 102 if a RF resource is utilized for an individual access point 102 or a group of access points 102(1)-102(X) that make up the mesh network 112. For example, the RF resource may be determined based on a determined potential throughput calculated based on the conditions data. In some examples, the machine learning algorithm may include multiple models that may be updated based on historical data.
For example, historical data can include, but is not limited to, conditions data previously observed at various access points, communication resources used by various access points (e.g., wired or wireless resources, radio access technology (e.g., 4G, 5G, Wi-Fi, microwave, and the like), network conditions, measured throughput, and the like. Such historical data and network performance can be used to train one or more machine learning algorithms to optimize a mesh network, as discussed herein.
At operation 606, a computing device can determine a radio frequency (RF) resource to be utilized based on the potential throughput. For example, in some cases, the RF resource may include unlicensed spectrum. For example, unlicensed spectrum may include a number of unlicensed RF bands, such as Wi-Fi, Bluetooth, etc., each of which may have different characteristics that may affect the mesh network in a different way. Similarly, licensed spectrum may include a number of licensed RF bands, such as RF signals according to 3rd Generation Partnership Project (3GPP) protocols, Universal Mobile Telecommunications System (UMTS) protocols, Long Term Evolution (LTE) protocols, Fifth Generation (5G) protocols, etc., that each include different characteristics that affect the mesh network 112 in a different way. Each access points 102(1)-102(X) in the mesh network 112 may support both licensed RF bands and unlicensed RF bands and each access point 102(1)-102(X) may be configured to receive an instruction from the centralized database of the core network 108 to utilize a specific RF band or a combination of multiple RF Bands based on the conditions data that was provided to the centralized database of the core network 108.
At operation 608, a computing device can cause the at least one backhaul link to utilize the RF resource. For example, the backhaul link can include a link between one or more access points of the mesh network. For example, once the machine learning component 310 has determined the RF resource for each access points 102(1)-102(X) and/or 202(1)-202(Z) in the mesh networks 112 and 212 to utilize, the communication component 306 may send a signal to the access points 102(1)-102(X) and/or 202(1)-202(Z) instructing them to communicate using the determined RF resource.
As shown in
For example, at operation 702, a computing device can monitor at least one backhaul link included in a mesh network. For example, a mesh network 112 may include a number of access points 102 that communicate via links 110 that operate using a type of RF signal. The computing device may include one of the access points 102 and may monitor the links 110 and data associated with the links 110.
At operation 704 a computing device can determine at least one conditions data associated with the backhaul link. For example, the access points 102 may store an agent that reports conditions data to the centralized database stored at the core network 108. For example, the agent stored at the access point 102 may monitor conditions data, such as weather data, signal level, a signal quality, a packet loss rate, interference, an uplink rate, or a downlink rate, and report the conditions data to the centralized database at the core network 108. In some cases, the conditions data may include a location of the access point 102 or nearby access points 102(1)-102(X) such that the centralized database at the core network 108 may determine a distance between access points 102. For example, access points 102(1) and 102(3) may have a greater distance between one another and may require a RF with a lower frequency and further range in order to communicate via the link 110(Y) than access points 102(1) and 102(2) that are closer in distance and may communicate using a RF with a greater frequency and shorter range via link 110(1).
At operation 706, a computing device can send conditions data to a remote computing device. For example, once the conditions data are determined the access points 102 may send the conditions data to the centralized data base at core network 108 and/or the base station 214.
At operation 708, a computing device can receive an instruction to operate the backhaul link using at least one radio frequency (RF) resource. For example, the access point 400 may include unlicensed RF band radio(s) 408 configured to transmit and receive via unlicensed RF bands, e.g., Wi-Fi, Bluetooth, etc. In configurations, a licensed RF band radio(s) 408 is configured to transmit and receive via licensed RF bands, e.g., transmit and receive RF signals according to 3GPP protocols, UMTS protocols, LTE protocols, 5G protocols, etc., for communication with components of the network 100 and/or 200. The access point 400 may receive instructions to operate using the unlicensed RF band radios(s) 408, the licensed RF band radio(s) 410, or a combination thereof.
While several possible examples are disclosed above, examples of the present disclosure are not so limited. For instance, while various conditions data and RF resources are discussed for use with the system, other conditions data and RF resources can be utilized in a similar fashion. In addition, the location and configuration used for various features of examples of the present disclosure such as, for example, the layout of the networks 100 and 200, for example, can be varied according to a particular network, UE, access point, or location that requires a slight variation due to, for example, size or power constraints, the type of processing required, or regulations related to transmission interference, for example. Such changes are intended to be embraced within the scope of this disclosure.
The specific configurations, choice of materials, and the size and shape of various elements can be varied according to particular design specifications or constraints requiring a device, system, or method constructed according to the principles of this disclosure. Such changes are intended to be embraced within the scope of this disclosure. The presently disclosed examples, therefore, are considered in all respects to be illustrative and not restrictive. The scope of the disclosure is indicated by the appended claims, rather than the foregoing description, and all changes that come within the meaning and range of equivalents thereof are intended to be embraced therein.
