2.1 COVERCELL 25K REPEATER NETWORK SERVICE CONFIGURAT
ION
CoverCell 25K RF Repeater receives cellular 800MHz and PCS 1900MHz BTS signals
through a donor antenna installed outside of a building. The signals are amplified, filtered, and
transmitted through a coverage antenna inside of a building. In the reverse, it receives terminal
signals through a coverage antenna and transmits the signals to cellular and PCS BTSs through
a donor antenna.
CoverCell 25K RF Repeater has following functions;
- Type of Modulation : CDMA (Cellular, PCS)
- Frequency/ Band Select using cavity filters
- Bandwidth Setting using PLL, Digital Filter
- Output Control using AGC/ALC
- Gain Control using attenuators
Figure 1 illustrates CoverCell 25K network configuration in a site. As seen in the Figure 1, the
donor antenna is installed towards PCS and cellular BTSs and the coverage antenna is located
in a place to cover approximately 25,000 square feet.
