Hi,
I want to know why the GSM-900 bandwidth has a gap of 20 MHz between the uplink and downlink bands???
In other words, what will happen if the band extends from 890-960 for uplink and downlink without any unused frequencies???

we use dedicated frequency band for uplink and downlink and to seperate them we use a guard band
