The DoT wrote a letter to the service providers on July 17 asking them to submit report on call drop issue by July 31.
It is learnt from sources that two-three operators have submitted their reports to the DoT on Friday and the rest will be submitting it by Monday.
The DoT’s July 17 letter said: “The issue of call drops in mobile networks has been reviewed in the department. It was felt that there is an urgent need to address the menace of call drops.
“Therefore, it is necessary that service providers undertake a special drive for Radio Frequency Optimization, analyse the reasons of the call drops and take appropriate steps viz. installation of more sites, adopting in-building solutions, augmenting existing RF resources etc. as the case may be.”
In their reply, the operators said: “In this regard, we request DoT to kindly issue a standardised audit procedure highlighting common streamlined process and requirements which are relevant for this purpose.”
