UK, England - Wireless Link @ 5GHz

Hi Guys,

I am not sure if electromagnetic regulations are exactly the same in all EU
countries, that's why I will rather ask...

I am planning to build a wireless link between two buildings @5GHz, it would
be more less 15 miles.
My questions are:

- what band at 5GHz can I use in the UK?
- can I use up to 1W EIRP?
- is it possible to use more than 1W EIRP? (if I have a licence or sth). If
yes, where can I get the licence from?

Thank you,
Martin

Hello Martin,

I was about to suggest checking on the Radiocommunication
Agency site because they used to have nice little guides to
various radio services (perhaps including the one you're
interested in). Apparently the RA has been replaced by
something called Ofcom (http://www.ofcom.org.uk/). Hopefully
there's something relevant on their site. Failing that, you
could probably telephone them.

Hope this helps,
- Andy.

Brilliant. That is what I was looking for...
Thank you. So they require a licence, but it's not expensive and EIRP is 2W.
(In EU is 1W, some countries 100mW).

Thank you,
Martin

I wonder if you could make do with a Wi-Fi access point on each end and use
high gain yagi antennas to cover the distance. I have heard of people being
able to "talk" many miles using such a setup.

A high-gain Yagi increases your effective radiated power
(increases the the amount of your radiated power that goes
in a given direction), which might effect license
requirements.

aiui, in the US that's permissible for point-to-point connections, too, so
it's worth checking if the same is true in the UK.
