Hello, Quick question....what about Waverider? (http://www.waverider.com) my understanding is that it uses a different frequency which does not require licensing. I know they have non LOS, but I'm not sure what the range is.
Would be interested to hear what the view is of their technology. (uhm, ya...I'm a shareholder from a while back).
