WHAT IS GSM?GSM is a TDMA based wireless network technology developed in Europe that is used throughout most of the world. GSM phones make use of a SIM card to identify the user's account. The use of the SIM card allows GSM network users to quickly move their phone number from one GSM phone to another by simply moving the SIM card. Currently GSM networks operate on the 850MHz, 900MHz, 1800MHz, and 1900MHz frequency bands.

WHAT IS USE OF GSM BTS IN FUTURE?Two highlights in the rich development of the 3G networks are advanced technologies and high efficiency. the GSM network is the most widely applied network in the world. the GSM network is still favored and constantly evolves due to the maturity of technical applications and business models.



Features of Flexi EDGE BTS & its fun

Interface between MS and BSCTransmission function, which manage transfer of traffic and control data between BTS and BSC.O&M Functions, which supervise the operation of the BTS.External Alarm collection.Measure Uplink and downlink signal..

EDGE DUAL TRX MODULE (EXxA)The Dual TRX Module is a two-carrier TRX.Support Double Power TRX (DPTRX).RF part with 2 independent transmit (TX) chains and 4 receive (RX) chains

When using 2 TRX we have to use EWxA to combine 2 transceivers in one.DTRX connected to system module via single Gigabit Ethernet interface

Power feed from system module via single cable
