As per industry sources, the Department of Telecommunications (DoT) has held Bharat Sanchar Nigam Limited (BSNL) responsible for delaying 4G network rollout.

According to DoT, BSNL’s act of sending back the proposal to submit the tender document has made it apparent that the telco wants to delay the 4G rollout process.

The DoT committee set up to review the bidding terms for 4G equipment procurement, had recommended the use of core network from domestic companies besides blocking investment in 2G altogether which though contributes around 60 per cent revenue to BSNL.

Earlier the panel had written to the DoT, seeking a clarification on the network expansion of as many as 49,300 2G and 3G sites to 4G at a cost of nearly Rs 23 billion. The panel, in its letter, had stated that having two different cores for a 4G network would impact the quality of service.

As per DoT, however, BSNL’s act of sending back the letter has created disruptions in the whole process of trying an indigenous product in the telecom network.
