4, two-port standard design, installation is very easy;
5, the device uses the Integration of methods to improve stability of the equipment;
6, using ALC control, continuously adjustable output level;
7, intelligent monitoring, fault alarm and remote maintenance (remote feature is optional);
8, high linearity power amplifier, stable performance;
9, the design of lightning protection, lightning protection systems.

Scenario:
 
       Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages and so on.
       Indoor: Hotels, exhibition centers, basements, shopping malls, office buildings, and other packaging area.
 
Mainly applicable to this case:
       Repeaters can find the installation place can receive pure BTS signal at strong enough level relay station as the reception level should exceed -70dBm; and to meet the requirements of the antenna isolation, in order to avoid self-oscillation.
