Techdirt raises an interesting question about this new Xmax broadband wireless technology, which "whispers" on occupied frequencies, allowing supposed dual-use of spectrum. The Reuters article that introduced the technology relies on three sources to vouch for the product's viability: the technology's inventor, the executive chairman of the company, and an "electrical engineering professor at Princeton University" who Reuters forgets to tell you actually sits on the company's board of advisors.

Techworld has a little more detail, claiming it can offer 40Mbps over 15 miles, using less than a Watt of power - all while inhabiting occupied frequencies previously thought unusable for high-speed connectivity. You can also read the above-mentioned Princeton professor's article in Microwave Engineering. Of course it will be interesting to read non-financially motivated engineer opinion on the technology, which is already being dubbed a Wimax competitor.
