You have the adjacent channels 121 to 124 for GSM 900 ? As far as I am
aware, adjacent channels will disturb each other. From what I know,
real networks usually have one free guard channel in between. So at
least the configuration of using adjacent channels should be checked
in advance (but you don't know how well different phones behave).
Best regards,
Dieter
