Illegal WLANs

Anyone that sticks an external antenna of say > 5dBi on an access
point/client device in the UK/Europe is probably breaking the law?
You are allowed 20dBi effective radiated power? (wow, they are soooo...
generous)

So that means that most modified WLANs in the UK are probably illegal.

When will the government pass legislation to bring in line with the States
where they can use 200mW with a 15.6 dBi antenna?

By the way forget your dlinks, linksys and netgear, they are just toys, the
demarctech/senao stuff cooks pigeons at 40 paces!

They have some "Crazy Eddie" prices... Insane...

Why do you think it's likely?

Actually, has anyone ever been prosecuted, or even told to stop it,
in the UK, for having an overpowerd link?

I think they will see the advantage of bringing broadband internet to remote
places and grant it.

I have not heard of anyone being prosecuted, so as long as you don't upset
anyone then I think its a rule that can be broken.

I think as long as you use antennas (not homemade) and transmitters that are
not going to "bleed" across amature bands or upset TV reception then you are
OK.

Just my thoughts

Do you know a cheaper place to get something similar (same receiver
sensitivity/output power)?
I would like to know as I have not got the hardware yet for link number 2,
and I need some weatherproof access points for a solid 3 mile link.

1 problem here is that population densities tend to be higher so
interference could be more of an issue - higher power levels would make that
worse. And its difficult to have laws that change between "rural" and
conurbation.

There have been a lot of safety scares in Europe about radiated power levels
with mobiles - these seem to be taken into account for other radio based
services.

Flip side is that if the equipment isnt made by someone wearing US only
blinkers, some bits of Europe allow more channels...

higher gain aerials do get used here - not sure how legal they are -
certainly some kit is only supposed to be used with manufacturer supplied
aerials.

Last time i checked it wasnt even legal to use 5G equipment out of doors in
the UK.

AFAIK cordless phones here dont use the 2.4G band, so 1 common interference
source in the US doesnt affect the UK (and maybe other bits of Europe)

if you use a good aerial it improves receive sensitivity as well as output
gain, so why do you think higher power is whats needed? Surely the important
part is a working link - overcoming link loss.

Actually this is exactly what recently FCC (i.e. US) rule changes did. They
recognised that interference is much more likely in densely populated areas
than in rural areas, and allow even higher power in rural areas. The RA
in the UK considered this, but rejected it.

It's very hard to make an antenna that will bleed frequencies not present
in the transmitter.
It can be done with enough effort using corroded connectors of some
sorts (forming diodes) but not otherwise.
The primary problem with homemade antennas will be a poorly known
radiation pattern.

eBay... Establish a business relationship, with the frequent sellers of
what you require...

I use the plastic tool boxes from Wal*Mart... 6.5 miles for my longest
one...

Does anyone know the U.S. regulatory stand on 802.11 b/g client cards that
work in U.S. and Europe? Is there any U.S. regulaton requiring b/g cards
sold in the U.S. to be restricted to channels 1 - 11? My client doesn't let
me specify the higher channels for scanning, but I believe that is a driver
and not a chipset restriction. I've had no luck getting the manufacturer to
tell me anything about trying to use this card in Europe or Japan.
