[dundee] re-peeking into other peoples backyard

I had a mail pointing out that terrestrial and airborne frequency and
power regulations are different. The legal sanctions for breaking these
are very stiff, check before you commit. The wifi frequencies are shared
across a lot of other unlicensed services some of which you may be able
to use but -- be aware you may ruin someone else's day or even harm them
using spectrum for unintended purposes. Radio modellers should use 27mhz
or 35mhz approved equipment to control the aircraft. 27mhz is
depreciated due to the use of high power CB and widespread model car
use( although they have another band at 40Mhz to save interference
destroying what can be expensive equipment). The 2.4 Ghz band is shared
with commercial control systems like cranes, mobile phones, wifi, low
power unlicensed users, and microwave ovens. There will be radio modules
that can be used, if the transmission criteria is not in general use
they will be expensive. Note unlicensed use of radio equipment is
tightly controlled by specification and restricted bandwidth, our
Government sells the rest or keeps it for Defence, it has a vested
interest in making you pay and catching you if you do not.

PS a small amount of bandwidth is used by public services and radio
amateurs. You also need a license to listen to radio in Britain,
unlicensed monitoring of transmissions could also give rise to legal
sanction(commercial radio listening is covered by the TV license, look
at its wording).

PPS The University may have a license for research use of some spectrum?
