Overview:

Work Frequency: CDMA450, LTE700 (A/B/C/D), IDEN800, CDMA800, GSM900 & EGSM, DCS1800, PCS1900, CDMA2000, WCDMA2100, AWS2100, LTE2600 and so on.

The elevator car is just like a big shielding box and it usually cuts off mobile signal. People are always very upset that: they are calling normally outside of the elevator and the call will drop at once when they enter into the elevator car. 

The elevator repeater is specially designed to optimize the phone signal in a elevator. The donor antenna on the top of elevator car receives the signal from BTS and transmits the signal to the elevator repeater by cable; the elevator repeater amplifies the BTS’s signal and transmits the signal to the inside of elevator car. The same way, it transmits the signal in opposite direction. So people wouldn’t worry about dropping call when they enter into elevator car.  

 Advantages:

1. Elegant and compact design.

2. Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

3. Adaption function, which can automatically control the gain of the repeater depending upon the strength of input signals, so that the link balance.
