1.3 Specifications
Description
This specification defines the uplink and downlink performance of the FiberDAS Fiberoptic Antenna
System. The terminal equipment consists of the Remote Transceiver and the Hub Transceiver Plug-In. The
latter is installed in the Hub Shelf. This system meets the requirements for GSM900, DCS1800 and
GSM1900 Class M3 micro-BTS as well as IS-136 TDMA, IS-95 CDMA, CDMA2000 and UMTS for
wireless PBX, in-building and campus coverage applications.
There are five frequency options for the FiberDAS: 850 MHz (AMPS), GSM900, DCS1800, PCS1900 and
UMTS. There are two downlink output power options: the P1 power option meets GSM 900 micro-BTS
M3 requirements and is available for the 850MHz and 900MHz versions only when they are part of a dual
band system. The P2 power option meets micro-BTS M3 requirements for 1800MHz and 1900MHz. For
850MHz and 900MHz, the High Power meets GSM micro-BTS power class M1 requirements and IS-136
in-building requirements for +20 dBm composite power. All of these system standards specifications are
met for optical loss of up to 4 dB.
