The presence of a multi-band radio does not guarantee support for a specific band or a specific regulatory profile. It has to be supported by design.
First determine the protocol -- 802.16-2004 or 802.16e-2005. A product could be designed using either protocol for 3.65 GHz support. Redline is using 802.16-2004 and Airspan is using 802.16e-2005 on their respective 3.65 GHz designs. Your reply suggested laptop support, so this implies 802.16e-2005 for some portability/mobility. Please note there are also some assumptions made about the base station capabilities based on the matching protocol.
Backing up to the top -- do I expect there will be US 3.65 GHz support in laptops (add-in cards or embedded) this year? No. It might occur in 2009, but I doubt the market demand is there to make portable products in this band. An equal effort on the base station side to support portability/mobility would also be required.
Approach the question from the needs of the market and if 3.65 GHz has mass-market appeal. The biggest opportunity in the US for 3.65 GHz is fixed wireless access for regional services and to address competitive business-to-business broadband. Similarly, I expect most of the portability/mobility interest will remain in the 2.5 GHz and under spectrum for good environmental penetration.
