1. General Warranty GSTeletech warrants to the original purchaser all standard products sold by GSTeletech to be free of defects in material and workmanship for the duration of the warranty period of one (1) year from date of shipment from GSTeletech. During the warranty period, GSTeletech obligation, at our option, is limited to repair or replacement of any product that GSTeletech proves to be defective.
b. Prior to repair, GSTeletech Customer Support will advise the customer of GSTeletech test results and will advise the customer of any charges for repair (usually for customer caused problems or out-of-warranty conditions). If returned devices meet full specifications and do not require repair, or if non-warranty repairs are not authorized by the customer, the device may be subject to a standard evaluation charge.
GSTeletech test reports or data indicating mean-time-to-failure, mean-timebetween-failure, or other reliability data are design guides and are not intended to imply that individual products or samples of products will achieve the same results. These numbers are to be used as management and engineering tools, and are not necessarily indicative of expected field operation. These numbers assume a mature design, good parts, and no degradation of reliability due to manufacturing procedures and processes.

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.
2. SYSTEM CONFIGURATION 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.

2.2.2 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.
2.2.3 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.
