There was general cheer in the WiMAX camp when the OFDMA-TDD was accepted as one of the approved air interfaces under the IMT-Advanced. Mobile WiMAX thus became one of the technologies using which 3G mobile services could be provided. It was considered an important development also because of the impact in Europe which had sharply divided bands for IMT-Advanced and WiMAX making it difficult for WiMAX operators access to the 2.5-2.69 GHz and 2.3-2.4 GHz bands.

However varied effects are now being seen across the world, leading one to wonder if a new virus has not been born. For example in UK, Ofcom the regulator is being sued for planning to auction the 2.5 GHz spectrum for WiMAX by T-Mobile, which would rather see it part of the IMT or LTE services.
In India the decisions by the WRC and the ITU seem to be have upset a hornet’s nest. With the ever powerful mobile operators lobby, which has already wrested a range of decisions in its favor, including barring any foreign companies from bidding for 3G spectrum, it has now embarked on a new ruse.
This is to wrest the allocation of the Mobile WiMAX spectrum in the 2.3-2.4 and 2.5-2.69 GHz bands in its favour citing the WRC decisions of commanality of air interfaces for LTE. The mobile operators are contending that as the WRC has accepted WiMAX-TDD as a part of IMT advanced, it is an enabling factor for the DoT to allocate to them the mobile WiMAX spectrum in these bands, which they would be able to use for their 3 G services. If WiMAX goes into the background owing to it, so be it.
