Abstract: Various methods, systems, and/or processes are described herein to create more sustainable configurations of wireless Access Points (APs), switches, and other network devices based upon network speed, client demand, among other factors. Clients may wirelessly couple to an AP using a variety of different technologies. The clients may be distributed over these frequency bands in an optimal manner allowing minimum use of transceiver power. The network link speed between the AP and the Ethernet switch may also be dynamically adjusted. These configurations may dynamically change over time as client demand or network traffic increases or decreases. In certain other configurations, the APs may have a higher wireless throughput than the ethernet connections to the network. In these instances, sustainable configurations can be achieved by powering down transceivers, radio chains, and/or processor cores. Traffic and other events may trigger the need for new sustainable configurations to be generated and applied.

Abstract: Various methods, systems, and/or processes are described herein that rely on a demand-based optimization logic that aims to improve wireless network performance. It involves selecting a floorplan, identifying access points associated with the floorplan, and assessing network demands of client devices within the area. Based on the demands, a demand-based power configuration is generated to adjust the output power of one or more access points. This configuration is transmitted to the identified access points to optimize network performance. By adjusting the power of access points to match the needs of client devices, more efficient and effective wireless network usage is realized.

Abstract: Devices, systems, methods, and processes for orchestrating and managing various lower-power modes in a variety of network devices within a network are described herein. Various network devices, such as access points may be capable of entering one or more lower-power modes of operation that utilize less electricity to operate. When initiating a lower-power mode, the various clients that the network device has been handling need to be handed off to a sibling AP nearby. However, when exiting these lower-power modes, these devices may need different amounts of time to reboot and/or resume normal operations. Thus, when deciding which clients to re-associate with the waking up network device, various considerations need to be weighed based on client needs and network device capabilities. Thus, a smart environmental controller (SEC) is utilized to coordinate these processes. The SEC can be a specialized device, or a logic distributed remotely or among the network devices.

Abstract: 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.
