A method for providing adaptive radio transmit power based on antenna pattern and elevation tilt measured through an accelerometer is provided. The method includes estimating an orientation of a wireless device using an orientation sensor integrated in or on the wireless device, and determining an adjustment factor for a transmitter of the wireless device based on the orientation. The method further includes adjusting output power of the transmitter of the wireless device based on the adjustment factor.

Improving transmitter Effective Isotropic Radiated Power (EIRP) may be provided. Improving EIRP may include sending a trigger frame to a client and receiving an uplink transmission from the client in response. A client Transmission (TX) power and a Received Signal Strength Indication (RSSI) associated with the client may be determined using the uplink transmission. Next, a client location may be determined. A pathloss associated with the client may be determined using the client location and the uplink transmission. A directional gain may then be determined using the client TX power, the pathloss, and the RSSI. An array gain is determined based on the directional gain. An Access Point (AP) TX power is adjusted based on the array gain.

In one example, a method may include providing an initial configuration for access points APs of a WLAN for an event at an LPV based on a profile for the event, a location of each AP for the venue, and anticipated demand at the APs; determining, for a particular time for the event, a distribution of wireless devices and channel support capabilities of the wireless devices different locations for the LPV; and providing an updated configuration for one or more APs at the one or more locations for the venue based on the distribution of the wireless devices and the channel support capabilities of the wireless devices determined for the particular time for the event at the LPV.

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.

A method comprises: at a radio access network configured to communicate with a user equipment (UE) wirelessly, an access and mobility management function (AMF), and a positioning service, and through which the UE attached to a network using an attach procedure with the AMF: upon receiving a request for a location of the UE from the positioning service, scheduling resource blocks, configured for acquiring location measurements, across multiple radio units (RUs) of the radio access network, such that the resource blocks are synchronized in time and frequency across the multiple RUs; by the multiple RUs, exchanging, with the UE, the resource blocks as synchronized, and acquiring the location measurements from the multiple RUs based on exchanging; and forwarding the location measurements to the positioning service to enable the positioning service to determine the location of the UE based on the location measurements.

On-demand positioning of 5G devices

A method, computer system, and computer program product are provided for prioritizing network traffic. An indication is received at a network controller that an alarm is activated at a physical site. A request is received from a user device to join a network at the physical site that is under control of the network controller, wherein the request includes a flag indicating an identity of a user of the user device and a priority status of the user. In response to authenticating the identity of the user via an identity provider server, the user device is authorized to join the network. Based on verifying the priority status of the user using the flag and authentication via the identity provider server, network traffic for the user device is prioritized.

Prioritizing network traffic for emergency services

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.

Systems and methods for reducing false radar detection

A multi-mode radio unit, and more specifically providing a multi-mode radio unit having a 7.2 split mode and a full gNodeB (gNB) mode may be provided.

The metric may be compared to a first threshold, and when the metric is above the first threshold, the MMRU may be caused to switch from the 7.2 split mode to a full gNodeB (gNB) mode.

Real-time radio self-calibration may be provided. The self-calibration may begin by sampling a Transmission (TX) signal. An achievable Error Vector Magnitude (EVM) for one or more frames may be determined based on the TX signal. Link budgets for clients may be determined using a TX power and a supported Modulation and Coding Scheme (MCS). A per packet TX power is adjusted based on the achievable EVM and a TX retry rate. The PA linearity of the radio may also be adjusted based on the achievable EVM and the link budget. The client may be regrouped into a new MCS based on the link budget.

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.
