Abstract: A method includes instructing, by a WiFi access node, a first device to communicate using an uplink frequency band with a first uplink power. The method also includes instructing, by the WiFi access node, a second device to communicate using the uplink frequency band with a second uplink power different from the first uplink power.

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: Techniques for distributed computation are provided. A plurality of edge computing devices available to execute a computing task for a client device is identified, and a first latency of transmitting data among the plurality of edge computing devices is determined. A second latency of transmitting data from the client device to the plurality of edge computing devices is determined, and a set of edge computing devices, from the plurality of edge computing devices, is determined to execute the computing task based at least in part on the first and second latencies. Execution of the computing task is facilitated using the set of edge computing devices, where the client device transmits a portion of the computing task directly to each edge computing device of the set of edge computing devices.

Abstract: Embodiments for preliminary antenna configuration for a radio in an access point are described. A preliminary antenna configuration with a first number of antennas transmitting at a first power level based on a maximum transmission power for the radio is used to determine a second antenna configuration based on network level factors, where the second antenna configuration includes a second number of antennas. The second antenna configuration is used to determine a third antenna configuration from the second antenna configuration, where the third antenna configuration includes a third number of antennas transmitting at a third power level based on a client transmission factors for a plurality of client devices connected to the access point. The third antenna configuration is used to transmit network traffic from the access point to the plurality of client devices using the third antenna configuration.
