"Stage is for me to ask ourselves are we going to continue plugging this line that all spectrum must be auctioned. There should be no delicensing because there will be enquiry by CAG or CVC or CBI. Are we in business of building India or we sort of cowards cowering our wounds," he said while speaking at Assocham's Mobile India Summit.
The CAG had alleged that government in 2008 allocated spectrum at less price which caused the national exchequer a notional loss of about Rs 1.76 lakh crore. The government had invited all-round criticism on 2G spectrum scam that was probed by CBI.
The Telecom Regulatory Authority of India (TRAI) chief said that it will be of no use to lay optical fibre in the country for broadband services without having enough spectrum.
"There is need for more spectrum. There is no point to lay fibre when no spectrum is available. I am talking of access spectrum," Khullar said.

He said that there is a need to delicence (free spectrum) telecom spectrum to spread use of broadband.
In 2012, TRAI had recommended to delicence (make free) 20 Mhz of spectrum between 1880-1900 Mhz frequencies for private and indoor use of telecom services.
TRAI Chairman said that there is also no progress on auction of 700 Mhz band-- the most efficient spectrum for telecom services at present-- for which the regulator has already given its recommendations.
Touching upon availability of spectrum with defence, Khullar urged that government department should end stand-off and release spectrum that can be used for telecom services.
