8 1. OVERVIEW COVERCELL 25K is a dual band repeater which can receive and transmit cellular and PCS signals in the shadow area, which BTS signals cannot reach. This system has 79dB and 85dB gain in the cellular band and PCS band respectively with 17dBm and 19dBm maximum power each. On the following condition, the band select function can be performed on each path in each band. - Cellular: A1+A2 or B1+B2 - PCS: 5MHz, 10MHz, 15MHz consecutive block select - Specific setting is possible using GUI The basic structure of CoverCell 25K illustrates that each module is built-in on each path in a body. The functions of each module are as follow. - 4-Plex Cavity Filter: Duplexing input and output signals in the Cellular and PCS frequency ranges and band combining. - Cellular Drive Module: including LNA, Local and PAM in the cellular band - PCS Drive Module: including LNA, Local, and PAM in the PCS band - Digital Filter: implementing the bandwidth setting and filtering using a digital technology each band - PSU (Power Supply Unit): Converting AC 120V to respective voltages for each module - Control Board: Checking and controlling each module - IO Board: playing a role as a terminal between PSU and each module
9 2. SYSTEM CONFIGURATION 2.1 COVERCELL 25K REPEATER NETWORK SERVICE CONFIGURATION 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.

132.2.2 Downlink Block Diagram CoverCell 25K is a dual band repeater that can handle cellular and PCS signals. Basically RF modules are separated from each path and band. One module can handle all the functions except 4 plexer and digital filter. Also one integrated chip which includes local and mixer consists a block and input detect process is performed to prevent external signals from affecting other signals after signals are through a digital filter.

142.2.3 Uplink Block Diagram The uplink path of CoverCell 25K does not use the input detect function. The gain of a donor antenna is high enough. Then, the last output power level is not necessarily high. Consequently, PAM is not necessary. The ALC function is monitoring the last output power and maintaining the output power to increase stability of the system.
