State-owned BSNL has offered to surrender its Broadband Wireless airwaves that it had bought from the Government. BSNL’s loss has tripled over the year and also there have not been many takers for its WiMAX service. BSNL had paid Rs 8313.8 crore for broadband access frequencies last year but now wants to return it to the government and wants a refund on the return of the frequencies. One of the reasons behind this is not a good business in the WiMAX area. Other companies working on the 4G technology prefer to opt for Long Term Evolution (LTE) for development and BSNL is the only firm dealing in WiMAX.
