Is normal found a GSM network working in to bands, normaly 850 with 1900 and 900 and 1800, but it is posible to use a 850 and 900 in the same network. also the frequencies from 850 and 900 do not overlap so i think in the point of view of network is no problem, but what about the terminals? how to make a balance between both network? we have a Huawei BSC6900 version R13 with DBS3900, any ideas? is a good option.
Thanks
hi friend
there's a overlap between 850 DL:869.2–894.2 and 900 UL:890.0–915.0. maybe at leas 5MHz Separation between DL and UL
we have all 850, and the start frec we havein 900 is 897 to 906. can work?
Most probably, there would be an interference even there is a guard band of 5 MHz. Interferences are due to out-of-band emissions of handsets; you cannot re-design all handsets not to emit anything in that overlapped frequency band while standards allow :(Quote:
