Description
Technical field
The present invention relates to a kind of mobile communication antenna, relate in particular to a kind of base station automatic recognition RET equipment and method that communicates with and base station.
Background technology
Antenna is the parts of base station transceiver wireless signal in the cordless communication network, plays a part very important in whole wireless network.Along with the technology fast development of mobile communication antenna, at present, RET system, i.e. electrical tilt antenna in cordless communication network, have been brought into use.
So-called electrical tilt antenna promptly refers to use electronics to adjust the portable antenna of tilt angled down.The principle of electrical tilt is by the amplitude size of the phase place of conllinear array antenna oscillator, vertical component and horizontal component and the change of synthetic component field intensity intensity, thereby the vertical directivity pattern of antenna is had a down dip.
Because the field intensity intensity of antenna all directions increases simultaneously and reduces, guarantee to change not quite changing inclination angle aft antenna directional diagram, the main lobe direction coverage distance is shortened, make whole directional diagram in the Serving cell sector, reduce area coverage again simultaneously but do not produce interference.Therefore adopt electrical tilt antenna can reduce call loss, reduce to disturb.
In addition, electrical tilt antenna allows system under non-stop-machine situation the vertical directivity pattern angle of declination to be adjusted, the effect that monitoring is in real time adjusted, and therefore the stepping accuracy also higher (being 0.1 °) at adjustment inclination angle can realize meticulous adjustment to network; The third order intermodulation index of electrical tilt antenna is-150dBc that more mechanical antenna differs 30dBc, helps eliminating adjacent the interference frequently and clutter interference.
AISG communication protocol physical layer specifies RET equipment is had two kinds of communication patterns: RS485 communication pattern and OOK communication pattern.The communication media that the RS485 pattern adopts is a split conductor; The communication media that the OOK modulating mode adopts is a coaxial line.
