According to Hindu Business Line, the Ministry of Defence has objected to the allocation of spectrum to the PSU. In a communication to the Department of Telecom, the Defence Ministry has said that BSNL's broadband services will cause interference to the Mobile Satellite Services (MSS) being used by the armed forces. It could potentially shut down Bharat Sanchar Nigam Ltd's WiMax-based broadband services. 

As per report, “Studies carried out by the expert group constituted by the DoT have indicated that unacceptable interference will be experienced by Defence MMS system due to spill over of operation of broadband wireless access equipment. The Defence downlink would be severely affected as the space to earth signals is very low power. The DoT is requested to desist from opening up the band for commercial services as also review the allocation made to MTNL/BSNL for roll out of BWA services,” stated a letter from Ministry of Defence to the DoT. 

Earlier, the Department of Space (DoS) had also raised objections to the use of 2.5 Ghz band for broadband wireless access (BWA) services. This could also have some ramification for the upcoming auction for BWA spectrum for private players.
