Multistandard intelligent modular supports antenna for cellular communications in multioperator environments.

摘要

System multistandard intelligent antenna compatible modular for cellular communications in multioperator environments, the antenna system adapted to have a diagram variable radiation, characterized in that it includes an array (7) of antennas (17) and a diplexer (8) adapted to separate being signals array (7) in different bands corresponding to different communication standards the system further comprising a communication module (10), (11), (12) for each of said standards, each of the modules communications (10), (11), (12) being adapted to have a RF subsystem (13), a subsystem software radio (14) and a subsystem beamforming (15) in which each of the modules communications (10), (11), (12) is connected to a base (16) of operators using said standards, and wherein each of the antennas (17) is connected via a duplexer / combiner station / divisor (20) adapted paraseparar channels, and each channel having a converter RF to intermediate frequency (21), a first analog to digital converter (22) and a digital demodulator (23), the system further comprising a forming beam (24) common for digital respective demodulators (23) adapted to combine the signals from the antennas (17) in accordance with a shaping criterion for every channel, wherein second digital converters to analog (22) and the converters intermediate / radio frequency (21 '') for each frequency channel are combined in a second combiner (20) from which the service is given to the different nodes (25) of said different operators.
