Small-site Repeater Provides An Affordable Solution To Solve The Indoor Signal Coverage Problems
Posted at: TradersCity --> Offers to Sell and Export
Posted on: Thu 14 Aug, 2008 3:53 am
The Small-Site Repeater works as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
