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: A wireless communication device is built from a base module and a plurality of front-end modules. Each of the plurality of front-end modules is configured to operate a different one of a plurality of radio frequency services and having a front-end module connector configured to removeably mate with a base module connector of the base module. A particular front-end module is connected to the base module. Upon connection of the particular front-end module to the base module connector, the base module reads information from a memory of the particular front-end module to determine the radio service that the particular front-end module is configured to operate and to supply the control signals to configure and control front-end circuitry of the front-end module to operate the radio service.

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: 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.
