Abstract: Techniques are provided for a delay compensated analog beam forming network. A transceiver implementing the techniques according to an embodiment includes an array of circuit elements. Each of the circuit elements includes an analog frequency converter to up-convert an analog signal to radio frequency (RF) for transmission and to down-convert an RF signal to an analog signal for reception. The circuit element also includes an analog beam weighting circuit configured to apply a beam weight to both of the analog signals to form a beam for transmission and reception. The circuit element further includes an analog delay element configured to impart a time delay to the analog signals. The time delay is based on the position of the circuit element in the array and is selected to compensate for propagation delay of the analog signals along the electrical path that couples the circuit elements of the array, reducing beam squint.

Abstract: System, device, and method for enabling transit access using a multi-beam phased array antenna. One method may include repeatedly transmitting, by a location transmitter positioned within a transit location within a transit system, a location signal identifying the transit location. The method may include receiving, by a mobile communication device, the location signal, initiating a check-in process, and transmitting a device signal identifying the mobile communication device. The method may include receiving, by a gate receiver positioned within a gate within the transit location, the device signal and analyzing the received device signal to determine that a holder of the mobile communication device is entering through the gate.

Abstract: Systems and methods for adaptive cancellation of carrier content includes receiving a signal, adaptively detecting an amount of carrier content in the received signal, generating a feedback signal for canceling out the carrier content in the incoming signal, and introducing the feedback signal for canceling out a majority of carrier content in the signal being received
