many thanks for your responce,
the problem is when I connect my MS to GPRS or EDGE (in diffrent MCSs) in download or Upload cases, the RX-Lev is -64 (for Exp.)then the degredation will start, after secound will be -80 then to -90, -97, -103 then will comeback to -70 and then to -85, -95, -100, …etc,
your feedback will be appreciate
