There is provided mechanisms for OTA calibration of an AAS. The AAS comprises N antenna branches, each of which comprises a respective subarray. The subarray of each antenna branch gives rise to a subarray antenna pattern extending over an angular interval. A method is performed by a test equipment. The method comprises obtaining measurement values for each of the antenna branches. At least one measurement value is obtained per each antenna branch. The method comprises determining one calibration factor value per antenna branch using the measurement values and taking the subarray antenna patterns into account. The method comprises applying the determined calibration factor values to the N antenna branches, thereby calibrating the AAS.

A system and method for real-time in-situ calibration of an Active Electronically Scanned Array (AESA) utilizes an S-parameter matrix-based EM transfer function between an end fire, unobtrusive, near field probe radiating element to minimize AESA look angle blockage. A sniffer probe is integrated in the AESA aperture of mechanical mounting frame or embedded with the AESA aperture structure. Hadamard orthogonal coding is utilized to simultaneously energize AESA elements.

A high frequency data network access system leverages commodity WiFi chipsets and specifically multi spatial stream (e.g., 802.11 ac) chipsets in combination with electrically steered patch array antenna systems at the subscriber nodes. In addition, for thermal control, the high frequency components are mounted to a main body that includes a heat sink and a chimney. These components are also separated from components operating at baseband to avoid interference.

A computer-implemented method for setting RF transmit power of a wireless device includes obtaining power response data for a power detector of the wireless device, the power response data providing a relationship between power detector readings from the power detector and measured transmit power of a transmitter of the wireless device; identifying a target power detector reading value corresponding to a target transmit power based at least in part on the power response data; initializing a transmitter gain of the transmitter to an initial transmitter gain value; obtaining a power detector reading value from the power detector; determining that a difference between the power detector reading value and the target power detector reading value is greater than a tolerance margin; and adjusting a transmitter gain value of the transmitter in a direction of the difference between the power detector reading value and the target power detector reading value.
