2. Applications:
|
BTS |
|
Repeater |
|
Indoor Signal Distribution System |
|
Donor Antenna |
The Repeater (BDA - Bi-Directional Amplifier) is connected via coaxial cable to a Donor Antenna and Service Antenna or DAS. Usually the Donor Antenna is placed outside the building where it has the best direction to get the qualified BTS signal for the input to the repeater, after the weak signal is amplified by the repeater, the signal will be distributed by the Service Antenna or DAS are where they can extend radio coverage to the areas with weak signal.
