摘要： The present technology allows coordination of channels of private wireless networks utilizing shared licensed and unlicensed spectrum. Wireless network operators in an enterprise location register to participate in a consortium and register licensed, shared, and unlicensed spectrum resources to be shared with other members of the consortium. The wireless network operators request an allocation of spectrum resources from the consortium. The consortium generates a radio resource management (“RRM”) plan for shared use of the licensed, shared, and unlicensed spectrum resources. The consortium combines the allocated licensed, shared, and unlicensed spectrum from each of the wireless network operators to meet the target RRM plan. The consortium monitors spectrum utilization to dynamically update the RRM. The consortium monitors spectrum utilization in real time to determine how closely the RRM plan matches the resources allocated to each wireless network operator.

摘要： Improved granularity of Coordination Groups (CGs) using sectorization may be provided. A plurality of sectors around a plurality of Access Points (APs) may be determined. Then, for each of the plurality of APs, it may be determined which sector client devices associated with each of the plurality of APs are in. Next, each of the plurality of APs may be caused to transmit to client devices in a first one of the plurality of sectors.

摘要： Differential time synchronization and scheduling may be provided. A first Access Point (AP) may wirelessly receive time-base translation parameters of a second AP. The first AP and the second AP may be neighboring. Next, a first transmission schedule for the first AP and a second transmission schedule for the second AP may be maintained. Then the second transmission schedule for the second AP may be translated into a time-base of the first AP based on the time-base translation parameters of the second AP. Then the first AP may transmit based upon the first transmission schedule for the first AP and the translated second transmission schedule for the second AP.

摘要： Devices, systems, methods, and processes for pre-association sounding executed between a user device and a network device are described herein. The user device may announce its pre-association sounding capability to the network device. The network device, also supporting pre-association sounding, may transmit a plurality of sounding frames to the user device. The user device may process the plurality of sounding frames, determine channel state information (CSI), and transmit the CSI to the network device. The plurality of sounding frames and the CSI may be exchanged between the user device and the network device prior to the user device associating with the network device. By the time the user device associates with the network device, the network device may already have the CSI required for beamforming one or more transmissions towards the user device. Thus, latency overheads associated with sounding are reduced by performing pre-emptive sounding while in a pre-association state.

摘要： In one embodiment, a method comprises: detecting, by a wireless mirror device in a wireless data network, link layer transmission of a wireless data unit between a wireless access point (AP) device and a wireless client device on a first allocated frequency channel at a first transmission interval; and transmitting, by the wireless mirror device based on detecting the link layer transmission, the wireless data unit at a second transmission interval on a second allocated frequency channel that is allocated to the wireless mirror device for a mirror transmission between the wireless AP device and the wireless client device at the second transmission interval.

摘要： This disclosure describes techniques for selecting network protocols using heatmaps. For instance, a system may receive radio frequency information from one or more sources located within an environment. The system may then generate heatmaps using the radio frequency information, where the heatmaps represent characteristics associated with different network protocols. The characteristics may include signal strengths, throughputs, data packet drop rates, data packet retry rates, and/or the like for various locations within the environment. A user device may then receive the heatmaps from the system. Using a location of the user device and the heatmaps, the user device may determine to communicate using a network protocol from the different network protocols. The user device may then establish a connection using the network protocol.
