Intel made their expected announcement of Rosedale II (not 2) today: The only unexpected news was the Roman numerals, it appears. Rosedale II will appear later this year, and sports mobile WiMax support, which is part of the 802.16-2005 specification, which differs from existing fixed WiMax (802.16-2004) in providing fixed, nomadic/portable, and mobile support. Rosedale II will appear in laptop cards first, and then later be integrated into the Centrino platform as a built-in function.
Intel apparently wants to position mobile WiMax firmly against Qualcomm technologies, such as HSUPA and HSDPA (high-speed uplink/downlink packet access), which is part of the GSM evolution. Intel maintains that the patent portfolio is more widely spread for WiMax, making royalties cheaper overall, and that mobile WiMax is more spectrally efficient. Spectrum issues worldwide need to be resolved to make mobile WiMax work outside of limited markets, however.
Important to note is that there are no substantial mobile WiMax network deployments to speak of, although trials are happening all over. The existence of these Rosedale II chips will provide the impetus for more testing and firm product deadlines, as well as an ultimate certification roadmap. I’ll be talking to Monica Paolini, an expert on WiMax, during a podcast tomorrow.
