In one of my earlier blogs, I pointed out that about 40 years ago 2 meters and 70 cm were basically uncharted areas. Now they are populated. Undoubtedly the future of ham radio is in our huge - virtually unused microwave allocations. They have the necessary bandspace to support wideband modes.
Jim, KC4BQK was first to repost this good video about 60 Ghz and the future of LANs. Blogger Craig Mathias from the Fairpoint Group dose a good job explaining 60 Ghz and the difference between WiGig and WiMedia. This could be something in the future that could include Ham Radio.
