摘要： To ascertain in a pseudo-incoming call sequence whether or not a fixed subscriber unit of a user is set to an operation condition to wait for an incoming call, when a pseudo-incoming call is transmitted from a pseudo-incoming call outputting unit of a base station managing apparatus to the fixed subscriber unit through a wireless base station and a radio communication path, the fixed subscriber unit outputs an incoming call response signal to the base station managing apparatus through the wireless base station. Therefore, the base station managing apparatus can recognize that the fixed subscriber unit is set to an operation condition. Thereafter, to prevent a telephone connected with the fixed subscriber unit outputting a ringer sound, in place of a ringer sound urging signal in an incoming call sequence, a sequence interrupting signal is output from an incoming call sequence interrupting unit of the base station managing apparatus to the fixed subscriber unit through the wireless base station. Therefore, the operation condition of the fixed subscriber unit can be recognized in the base station managing apparatus without bothering the user.

摘要： Certain features relate to systems and methods for optimizing the radio frequency characteristics of signals transmitted between a radio base station (RBS) and a distributed antenna system (DAS). A self-optimizing network (SON) entity can determine adjustments to radio frequency operations and management parameters at the RBS based on radio frequency parameters measured by a measurement and configuration module at the DAS. Adjustments to radio frequency operations and management parameters can include adjustments configured to compensate for signal latency caused by the DAS. Adjustments to radio frequency operations and management parameters can also include adjustments to signal gain due to noise rise caused by the DAS. The SON entity can also measure nominal receive power levels for the RBS for purposes of open loop power control.

摘要： 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.

摘要： An electronic device has multiple transmitters to transmit multiple signals. The electronic device also has a receiver to receive a signal. Moreover, the electronic device has a memory to store instructions and a processor to execute the instructions. The instructions cause the processor to send a test transmission signal from a transmitter of the multiple of transmitters, receive the test transmission signal at the receiver, and determine a gain of the test transmission signal. In response to determining that the gain is within a threshold range of an initial gain, the instructions cause the processor to send an indication that the receiver is operating as expected.
