Abstract: A wireless transmission system comprising a main circuit board having a first controller and a first connector assembly associated therewith; a removable and replaceable radio frequency module for transmitting and receiving wireless data, wherein the radio frequency module includes a second controller, a first module connector assembly, and a second connector assembly that is configured to couple to the first connector assembly; a removable and replaceable diplexer module for sending and receiving the wireless data at different frequencies, wherein the diplexer module includes a storage element, a first waveguide port connector, and a second module connector assembly that is configured to couple to the first module connector assembly; and a transition waveguide module having a second waveguide port connector that is configured to couple to the first waveguide port connector.

Abstract: A power supply system that includes a pluggable and replaceable modular power interface card and a separate main chassis component that can include AC to DC power conversion and regulation circuitry, a digital voltage display, and one or more card slots for receiving the power supply card. The modular power interface card can provide power to a network device that is connected thereto. The modular power interface card can include an isolation and protection unit that includes a voltage suppression subunit and a high voltage protection subunit, fusing, and a path to earth ground. The modular power interface card plugs into the main chassis and can be quickly replaced in the event of damage or failure, and can include light emitting diodes (LEDs) to indicate whether the remote device being powered is consuming current, which is useful during troubleshooting.

Abstract: A patch array antenna includes a base on which is defined a ground plane. A plurality of first patch elements are configured to resonate over a frequency range. Each patch element is isolated from the ground plane and disposed on the base over the ground plane so that an air dielectric is defined between the patch element and the ground plane. A plurality of parasitic second patch elements are disposed on the second base so that the second patch elements face the first patch elements across an air filled gap.

Abstract: A patch array antenna includes a planar base on which is defined a ground plane and feed positions that are electrically isolated from the ground plane. A plurality of patch elements are configured to resonate over a predetermined frequency range. Each patch element is isolated from the ground plane and disposed on the base over the ground plane so that an air dielectric is defined between the patch element and the ground plane. Each patch element defines a resonant portion that is electrically connected to a respective feed position. A feed network is defined on the base that electrically connects the feed positions to one or more output points on the base.

Abstract: A point to multipoint wireless communication system includes an access point having an antenna, a processor, and circuitry in communication with the access point antenna and controlled by the access point processor to transmit wireless electromagnetic signals to, and receive wireless electromagnetic signals from, an area. A plurality of subscriber units disposed within the area each has an antenna, a processor and circuitry controlled by the subscriber unit processor to transmit wireless electromagnetic signals to, and receive wireless electromagnetic signals from, the access point. The access point assigns instructions to the subscriber units based at least in part on the subscriber unit's past use of bandwidth.
