To address the issue BSNL sent letter to DoT offering to surrender the BWA spectrum in 17 circles, and to refund them Rs 8313.80 crore. BSNL will retain the spectrum in Maharastra, Gujarat, Haryana and Andra Pradesh. BSNL will continue to offer rural wireless broadband via WiMAX.

DoT also plans to auction this returned spectrum.

BSNL has problems with its WiMAX venture from the very first, as they are:

Spectrum Issue: BSNL & MTNL, PSU duo got BWA spectrum almost one year before the BWA auction in 2010. But the spectrum is given in non-standardized 2.4GHz band which is not popular. This band is not suitable for WiMAX or LTE and few equipments support this. At the same time private operators got the spectrum in 2.3 GHz band and will go for LTE-TDD way.

Problem with WiMAX:

Though BSNL rolled out WiMAX in certain circles, and it was committed to WiMAX, India is going to be LTE hub. All private BWA operators are said to be committed to LTE. Like LTE, there is no scope to 2G & 3G backward compatibility with WiMAX. Industry experts opine that WiMAX lobbies push BSNL to opt WiMAX, but it also makes BSNL isolated in interoperability and roaming arrangements.

BSNL WiMAX did not Take off Properly: BSNL wanted to offer WiMAX in a franchise route but the decision invites lot of controvercy. Ultimately BSNL had to scrape the tender processes.
