Fixed-Access Wireless ISP FREEDOM4 has achieved the world’s first seamless mobile WiMAX session handover between base stations operating at two different frequencies (2.5GHz & 3.6GHz). The technology was developed in conjunction with its partners, Airspan Networks, Bridgewater Systems and Starent Networks:


However at present mobile WiMAX technology is not being used for the most commonly recognised form of Mobile Broadband service in the UK, which is instead based on HSPA (up to 14.4Mbps maximum). LTE (Long Term Evolution) is also seen as a more likely candidate to replace HSPA in the future.

Today's development may give WiMAX a bit more muscle but the hill it has to climb is looking increasingly steep. LTE is further behind, yet some suggest that it could be cheaper and easier for mobile operators to deploy. The success of HSPA suggests that mobile providers probably don't mind waiting for LTE and they don’t appear to be in a hurry to adopt WiMAX.
