Mobile WiMax is Being Buried Alive?
WiMax news has been dominated by a London research firm’s recent announcement that mobile WiMax might be dead on arrival.
“Recent events have been unfavourable toward Mobile WiMAX,” says Frost & Sullivan’s Programme Manager Luke Thomas, referring to Sprint’s delayed deployment of its commercial WiMax network. The firm then focuses on the two aspects of mobile WiMax:
“In terms of indoor wireless broadband, Wi-Fi fits well in this space and with the emergence of 802.11n, which includes MIMO, throughputs would be far better than what MobileWiMAX can deliver…With respect to outdoor mobile broadband environments, users would expect Mobile WiMAX to seamlessly hand off to cellular networks in the absence of WiMAX reception. In reality this is not possible as mobile WiMAX is not backward compatible with existing cellular technologies.” (Centre Daily)
By their diagnosis, the future of mobile WiMax seems bleak indeed. However, the image they portray may be oversimplified to WiMax’s disfavor. For instance, most next-generation broadband technologies will radically change modes of operation, making them incompatible with prior hardware. And before you ask, yes, in this club is the much-championed LTE. So in any discussion of new mobile technology, upgrading existing equipment is almost a given. It’s certainly much more of an industry-wide hurdle than, as Frost & Sullivan make it seem, an obstacle of WiMax exclusively. And already the industry is moving towards a solution, with talks of multimode.
As for the talk of the 802.11n standard of WiFi: last I heard, parts of the standard were still under patent in Australia, and requests for Letters of Assurance were ignored. That’s not a good portent for the standard’s likelihood of approval, as fast as it may be. I’d much rather look to WiMax, which is set to launch in its first large U.S. metropolitan area, Baltimore, in September.
