Wi-LAN sues RIM over tranceiver patents

Comments

GavelOttawa-based company Wi-LAN just opened up a can of legal whoop-ass, dishing out healthy servings to not only RIM but Motorola and UTStarcom. Wi-LAN has patents relating to both CDMA and Wi-Fi, and the ones they’re claiming infringement on are “MultiCode Direct Sequence Spread Spectrum” and “Method and apparatus for multiple access between transceivers in wireless communications using OFDM spread spectrum“. Bit of a mouthful, eh? The two both deal with transcievers and how they decode information, which goes to show how RIM, Motorola and any other manufacturers make for juicy targets for Wi-LAN. As if these guys actually have a “Litigation Update” widget on their site…

WiMAX steps up to UMTS

Comments

WiMAXMobile WiMAX is making some headway in Europe, gaining ground on UMTS. The International Telecommunication Union has decided that OFDM-based technologies, such as WiMAX should be included in the ITU’s international IMT2000 standard. European countries such as Norway, Sweden, and the UK are touting the decision as a step towards fair play in the future of wireless technology.

“This is a good sign for technology neutrality becoming the accepted approach for spectrum auctions in the future,” says ABI Research analyst Ian Cox. “Mobile WiMAX products will start to appear in 2007 and can be used in unpaired spectrum, giving them an opportunity not available to UMTS.”

It’s good to see regulators realizing how huge WiMAX is going to be and paving the way for it to happen.
