Abstract: Systems, methods, and computer-readable media for an integrated Wi-Fi Access Point and cellular network Radio Unit (RU) include a communication system interfacing with a wired network for communicating Wi-Fi traffic and cellular network traffic, the communication system integrating a Wi-Fi Access Point (AP) with a cellular network Radio Unit (RU). The Wi-Fi traffic and cellular network traffic can be processed in the communication system. The communication system can interface with at least one programmable Radio Frequency (RF) front end configured for wireless communication over one or more frequency bands for Wi-Fi traffic and one or more frequency bands for cellular network traffic (e.g., 5G, LTE, Wi-Fi).

Abstract: Techniques for efficient network probing are provided. Coherence data is received from a plurality of access points (APs), where the coherence data indicates, for each respective AP of the plurality of APs, coherence bandwidth for a plurality of subcarriers. A mapping is generated indicating, for each of the plurality of APs, sets of subcarriers that can be interchangeably sounded. Two or more APs of the plurality of APs that can jointly sound a first subcarrier of the plurality of subcarriers are then identified based on the mapping, and the first subcarrier is allocated to the identified two or more APs for future sounding.

Abstract: In one embodiment, a system for allocating clients between radios of an access point is disclosed. The system includes a first antenna coupled to a first radio, a second antenna coupled to a second radio, and a monitoring radio coupled to the first antenna and second antenna. The system includes computer-readable instructions that cause the system to receive at the monitoring radio, a first client attribute from each of a plurality of first client devices, and a second client attribute from each of a plurality of second client devices, and provide each aforementioned attribute to an optimization function. The system determines, with the optimization function, that one of the first radio and second radio will optimize performance for at least one device of the plurality of first client devices and second client devices and steer the at least one device accordingly.

Abstract: Methods and systems for distinguishing between radar signals and Wi-Fi signals are provided. When a set of electromagnetic signals are received, various tests are performed on the signals to determine if the signals are associated with radar pulses or if the signals are more likely to be associated with stray WI-Fi signals or other non-radar interference. One such test relies on the relatively small variance of frequencies used by radar pulses when compared to the high variation of Wi-Fi signals. Another test relies on the relatively low peak to average power ratio of signals associated with radar pulses when compared to Wi-Fi signals. The tests described herein are an improvement on existing methods for distinguishing radar signals from Wi-Fi signals and result in less switching of Wi-Fi channels due to erroneously detected radar signals.

Abstract: An electronically a steerable and switchable antenna array is provided that can produce a first beam with a first coverage range and a second beam with a second coverage range by selecting one of a first and a second beamwidth for both the first and second beams; in response to selecting the first beamwidth: switching signal inputs to narrow-beam antenna arrays; steering the first beam to one of a first positive, negative, or zero offset position; independently steering the second beam to one of a second positive, negative offset, or zero offset position; and transmitting signals received from the signal inputs via the first beam and the second beam; and in response to selecting the second beamwidth: switching signal inputs to wide-beam antenna arrays; and transmitting signals received from the signal inputs via the first beam and the second beam.

Abstract: In one embodiment, a method includes identifying a number of configured proactive repetitions in downlink transmissions from the base station, selecting k antenna states for receiving repetitive downlink transmissions among the number of antenna states, where k equals the number of configured proactive repetitions, and where each of the k antenna states corresponds to each of the repetitive downlink transmissions, transmitting a CSI report for each of the k antenna states to the base station, where a CSI report for an antenna state is used by the base station to adjust configurations for the corresponding downlink transmission, receiving signals for each of the k repetitive downlink transmissions from the base station using each of the k antenna states, and decoding the downlink transmission based on k sets of received signals, each of the k sets being received using each of the k selected antenna states.

Abstract: Embodiments herein describe mounting one or more lasers onto an AP to generate a laser pattern on a surface representing the coverage area of an antenna in the AP. In one embodiment, the antenna is a steerable antenna that can be electronically or mechanical steered to point to different directions (without moving the AP as a whole). The laser or lasers can be used to visualize the coverage area of the steerable antenna when pointing in different directions. Advantageously, a technician can use the laser or lasers to identify a location where, if steered, the antenna would provide the desired coverage area. The technician can then steer the antenna to point in that direction to provide the desired radio frequency (RF) coverage.

Abstract: System, methods, and computer-readable media for switching a dynamic radio of a single RU between Radio Access Technology (RAT) protocols based on a Software-Defined RAN intelligent controller (SD-RIC). The SD-RIC efficiently assigning RAN resources by converting a radio access point to either 5G or Wi-Fi based on the load conditions and the number of users seen on the network, so that it appropriately servers the customer and end devices. To determine the load conditions may be based on active users on a particular cell, and then the resource utilization cue is a connection latency. A single radio unit includes a primary radio and a secondary radio, each being independently tuned. The primary radio is static while a secondary one can be influenced based on the conditions, turning into N-RU or Wi-Fi.
