[Freedombox-discuss] "Innovation Under Austerity"

[bnewbold at robocracy.org]

As another example, Microsoft Research demonstrated frequency shifting of 
commodity 802.11.bg radios to TV channels ("WhiteFi") as part of their 
whitespace dynamic spectrum use research:

High-throughput 802.11* is notoriously hard to implement via direct 
synthesis using software defined radios. Mixing the frequency of a 
commodity miniPCI wifi adapter around to a different band with a "simple" 
analog radio frequency circuit as a DIY solution is very appealing to me, 
but the 3.6GHz Ubiquity equipment is almost certainly worth their cost on 
reliability and performance grounds.

>>> Shortly after 1hr 18min into this video by Eben Moglen entitled "Innovation Under Austerity," a man is asked to step up to the mic and discuss the ability to take a device an move data from one area of the spectrum to another.  He talked specifically about WiFi and cable modems, and a transverter (linear translator), and move it from WiFi to another area of the free spectrum (by using an amateur radio license).
