India's Reliance Communications has acquired a 90% stake in eWave World, a UK-based WiMax broadband wireless operator. RC hopes to use eWave to help it launch 4G 'Mobile Broadband' services around the world.

The stake itself is worth roughly £55m, although RC has not revealed its plans for the UK firm. Presently the group hopes to launch some form of WiMAX based 4G service in 50 countries by 2012.
