It would be kind of grey. He was aiming for 5.8 which is an open band in the US, although his bandwidth was way above the width of that channel. Generally though unless you are actively impeding someone else or, god forbid, you're on government or medical channels, you're pretty okay and you are unlikely to get hunted down. People get nabbed for jamming cell phones and such but if you are using it rarely and not using a massive amount of power, nobody will notice.
Good practice is to stick to the open bands: http://en.wikipedia.org/wiki/Amateur_radio_frequency_allocations#ITU_Region_2 http://en.wikipedia.org/wiki/Amateur_radio_frequency_allocat...
Also, he says he's aiming for a radar band: "The reason I chose to use 5 – 6 GHz band was because there is a band reserved for radars around 5.8 GHz and this range overlaps with 5 GHz WLAN."
- wtallis 12y agoSince 5.8GHz wifi devices are required to detect and avoid frequencies actively used by radar systems, it would be pretty straightforward to just use your laptop to check if it's safe to do a hobby radar project in your location. It's really easy to make this a very low-risk project.
- Johnythree 12y agoThe issue is not Licensing, but Type Approval. Even on the ISM bands (http://en.wikipedia.org/wiki/ISM_band http://en.wikipedia.org/wiki/ISM_band) any transmitter must still be submitted for Type Approval Testing. The only exception to Type Approval is on the Amateur bands where "homebrew" is permitted (and encouraged). However the Amateur Regs specifically rule out any commercial use. The only way this could legally be operated is in a professional quality screened room, or if the University has an "Experimental" class radio license.
- hwillis 12y agoIt's in a legal band for any use, but you are correct, the output power is 300-600 times too high to be unlicensed.
