The Antenna Interface Standards Group (commonly referred to as AISG) is a non-profit international consortium formed by collaboration between communication infrastructure manufacturers and network operators with the purpose of maintaining and developing a standard for digital remote control and monitoring of antenna line devices in the wireless industry.

The first English-language release of "Antenna House XSL Formatter" was announced on the XSL-List mailing list on 22 November 2000. [2]Antenna House XSL Formatter V1.2 Alpha was one of six XSL Formatters that provided the test results [13] for the test suite for the XSL 1.0 Candidate Recommendation that was required for XSL 1.0 to proceed to the Proposed Recommendation stage.
There are two basic modes of operation for a CEA-909 antenna, mode A and mode B. Mode A allows for communication only from the tuner to the antenna and Mode B allows for bidirectional communication. A 14-bit pulse-width modulation data stream is sent to the antenna and if the antenna is mode B a 10-bit data stream is sent back. The timeout ...
Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
This is a category of articles relating to free software for making or viewing Portable Document Format (PDF) documents. That is, software which can be freely used, copied, studied, modified, and redistributed by everyone that obtains a copy. Typically, this means software which is distributed with a free software license, and whose source code ...
A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
An antenna control unit utilizes the resulting difference signal to select the optimum signal strength for the particular step of the search pattern. This system is particularly applicable to extremely high frequency communication channels (86 GHz and above) which are subject to atmospheric distortion and noise .
