Answer for SRINA on GSM Antenna company. The company I use to work for had very good luck out of Swedcom Antennas on their Erisson GSM edge NW. Hope this helps.

They worked much better than the Andrew and kathernia.

A contact would be Johan Forsman
Swedcom Antennas : http://www.sewdcom.com

or 650.348.1190

Hi,
I am looking for GSM and 3G network simulators to test SIM cards and handsets for their behaviour under different network settings (i.e bands, proactive command support of handsets, behaviour of 3G handset with 2G phones in 3G network, etc.)

Anyone can give me a list of such equipment in the market (manufacturer+model name)
Cheers and thanks in advance
Rohit

HI Vijay and hardev
for every TRX or CU u have to have 2 timeslots of E1 i.e. 128 kbps.and in one TRX 8 subscr. can talk simulta. with full rate encoding but with half rate it will get double. but in each sector u will have to define BCCH and SDCCH it’ll take ur 16 kbps in that 128.
and 1 E! has 2048 kbps bandwidth. so u can easily calculate. for each configuration depending upon how many TRX are defined in that E1

Hi davinder
In Nokia BTS

TSGA-normal trx G for GSM 900
TSGB- TRX with EDGE 900 mhz
TSDA-normal trx for DCS 1800
TSDB-TRX with edge tech 1800 mhz
BB2A-base band card for normal TRX
BB2F/E-FOR EDGE TRX
M2LA-MULICOUPLER WORKS AS SPILITTER IN Rx PATH
DVGA-DUPLEXOR WE REQUIRE THIS IF WE USE COMMON PATH FOR BOTH Tx AND Rx AS GEN. WE DO
WCGA-WIDE BAND COMBINER- TO COMBINE THE Tx FOR TRANS. FROM SINGLE DUPLEXOR.
RRI AND E1/T1-ARE TRANSMISSION CARDS FOR Abis CONNECTIVITY WITH BSC.
BOI- HEART OF BTS, SOFTWARE RESIDES IN TO THIS ONLY ALL SAVED CONFIGURATION RESIDES IN TO THIS EXCEPT TRANSMISSION RELATED BECAUSE ALL THE TRANSMISSION RELATED PARAMETER ARE SAVED IN ITS TRANSMISSION UNIT i.e. RRI OR E1/T1
