Reply To: Call drops in GSM

Wallis Dudhnath

For your case a RCA is required.

Factors that influence call drops include but is not limited to
the following; Transmission issues (high Bit Error Rates), Handover between
sites that have not been optimised and Co-Channel interference.

Check if your BTS has any obvious harware faults that require a correction (e.g.
latest fix / correction Package).
