"I will be joining from tomorrow," Khullar told PTI.
Khullar, 59, will head TRAI at a time when the regulator is in the line of fire of telecom operators for its recommendations on spectrum auction in which it has proposed steep high base price for radio waves. The auction is to be undertaken before August 31 this year.
The new TRAI chief will have to deal with the telecom industry which is widely divided.
While GSM operators, through their association COAI, have alleged the latest TRAI recommendations are favourable to those operators which provide dual technology services, the latter have alleged that TRAI has ignored various issues resulting in big benefit for the old GSM players.
