Bangladesh Telecommunication Regulatory Commission (BTRC) has deferred the auction of 1800 MHz and 2100 MHz spectrum until June 10. Its warning of bringing new entrants has already failed to tame the boycotting mobile operators. Now the regulator is blackmailing the mobile industry on QoS. Sunil Kanti Boss, chairman of Bangladesh Telecommunication Regulatory Commission, said the mobile phone operators need more spectrum, and if the leading operators do not take part in the upcoming spectrum auctions, they cannot offer quality services. “If operators fail to ensure quality services, they will be penalised for it,” the BTRC chairman said at a press conference at his office yesterday, on the eve of World Telecommunication and Information Society Day 2015.
