Description:

The Remote Electrical Tilt Unit (R.E.T.) allows for accurate control of antenna tilt eliminating site-access requirement, allowing the tilt to be adjusted remotely from the Base station/network control center and only in a matter of minutes. This allows for timely and accurate response to changing capacity requirements of the network. It can save your time, money and safety for the physical work access the sites. The solution comprises of a Motor driven Antenna, with communication to the BTS and a microprocessor that controls the communication and performs supervisory functions. Most of the R.E.T. systems use the AISG protocol (Antenna Interface Standard Group) which is an open specifications for the control interface for these systems and SRT R.E.T. is compliant to AISA 2.0 / 3GPP.


Remote Electrical Tilting device(RET) converts the angle of the antenna beam electrically through the control of antenna pivot when the phase shifter is connected mechanically. RET converts and adjusts the antenna angle by controlling the motor through RS485 electric signal in the main system. RET product can change the number of channels according to the customer’s required condition such as the channel 1, 2, 4, 8, 13, and 16.
