Telecom tribunal TDSAT on Monday gave 10 days more to the Department of Telecommunications (DoT) to file its responses to US based chip maker Qualcomm’s petition against the reduction of the validity of wireless broadband spectrum allotted to it and the roll out obligations.

DoT had reduced the validity of Qualcomm's Broadband Wireless Access (BWA) spectrum to 18 years and six months, from 20 years.

A TDSAT bench, headed by its Chairman Justice S B Sinha, accepted the DoT request and granted it 10 days' time.

Qualcomm also got a week’s time from the tribunal to file rejoinder over DoT's reply. It directed to list the matter on August 3 for next hearing.

Qualcomm's roll-out obligation period was also reduced from five years to three and a half years, which has been challenged by the chipmaker before the Telecom Disputes Settlement and Appellate Tribunal.

DoT which was ordered by TDSAT on June 1 to file reply within four weeks, could not file the reply on Monday and sought more time.
