Hi Chen
DBS 3900 BTS’s are MCPA BTS’s,their TOC power depends on the no. of TRX’s i.e,no. of modules.It has a Maximum of 80 W O/P power with 8 TRX’s with 10W power each,if you use 4 TRX,u can have 20W O/P power for each TRX.
Im working with HUAWEI DUAL MODE BTS DBS3900 for GSM / UMTS. We have a problem with power signal. This is happend when INCREASE THE TRX. The power signal is lower than the HUAWEI specifications. For example, for GSM only with 5 TRX, 2.8 watts per TRX…
Have anyone of you information about this type of problem?
