    Abstract: Devices, systems, methods, and processes are described herein that can reduce network communication overhead by reducing data that is sent. This reduction in data can be achieved by reducing the requests for data related to the buffers of one or more network devices. This buffer status data reduction can be achieved by predicting the current status of the buffers in other network devices. When the buffer predictions are sufficient, the need to request or poll for buffer status reports can be reduced. The buffer predictions can be evaluated through one or more confidence levels. These buffer predictions and confidence levels can be generated by one or more machine learning processes that are configured to operate on one or more network devices. Based on the confidence levels of the predictions, the number of buffer status report polls and of any unsolicited buffer service reports can be reduced.

    Abstract: In one embodiment, a control device associated with a wireless network of a given location determines a reference quality of location readings between access points and client devices based on using substantially all of an available wireless communication bandwidth. The control device may then determine channel state information (CSI) between the client devices and access points for each orthogonal frequency-division multiple access (OFDMA) resource unit (RU), and selects a subset of RUs for allocation to each respective client device, based on the subset of RUs allocated to each respective client device i) surpassing a determined threshold of certain parameters of the CSI, while also ii) providing a minimum quality of a location reading based on using only the subset of RUs as compared to the reference quality of location readings. The control device may then allocate the selected subset of RUs to each respective client device for location-preserving OFDMA-signaling-based communication.

    Abstract: Increased channel availability may be provided. A computing device may receive radio channel information comprising a radio channel to operate within and an incumbent indication indicating whether an incumbent is using the radio channel. Next, power to operate a radio at may be determined based on the incumbent indication. When the incumbent indication indicates an incumbent is present on the radio channel, determining the power to operate the radio based on the incumbent indication comprises: i) determining a first power level for subcarriers in the radio channel that are non-overlapping with a portion of the radio channel used by the incumbent; and ii) determining a second power level for subcarriers in the radio channel that are overlapping with the portion of the radio channel used by the incumbent wherein the first power level is greater than the second power level. The radio may then be operated at the determined power.
