Telecom Regulatory Authority of India said on Tuesday that the quality of services by private mobile operators like Airtel and Hutch was poor in Mumbai mainly due to less number of cell sites being put up by the service providers.
"The quality of service of the networks of Airtel, Hutch and BPL are not as per the prescribed standards in respect of coverage, interface and call drops at several locations," TRAI said in a statement.
All the service providers, in common, have coverage problems in several locations as these are currently being covered remotely by sites from neighbouring locations.
Due to coverage from remote base stations, the signal strength in these areas is barely sufficient to mature a call, TRAI said.
TRAI is also of the view that GSM service providers have already crossed the benchmark for allocation of additional spectrum.
