802.11b wireless link signal travels over 1km

Get a load of this. Its a great writeup to making your 802.11b signal travel a greater distance.

Watch the guy gets arrested and executed for being a spy (for using it to transmit to his handlers) :D

Actually, wouldn't this require some type of licensesing by the FCC in the US?

Actually it does not require licensing in the US. I have an antenna on my roof that does 802.11b to a tower 3 miles away. I get the full 11mbit/sec connection. The company that provides this has 6 towers around town to point to, and they do a 30 mile radius.

I just have a directional antenna on top of my house.

Here you can read all about it: http://www.rwnx.com/

Note they quote pretty high prices, but in fact local ISPs resell their service/equipment for a lot less. It is still expensive, I pay $90/month for 2mbit/sec service. But, at the time I got the service it was that or 28kbs was the best available at the house (no cable/dsl and ISDN was more expensive)

How do you secure your connection? Seems pretty open.

[Mike123abc]

I would not call the connection secure. Yes it uses the 11b security which has been shown to be very weak. Of course secure web pages should encrypt even more. My antenna is very directional and it would probably be hard to pick up the signal unless you get up on the roof very near the antenna.

The tower transmissions back to all the users of course would be pretty much in the open, using only the 11b encryption only if they used a high gain directional antenna to point at it. My house is far from the street given my multi acre lot, dont think the tranmissions will be picked up casually.

So, I guess the security is that you would have to have a 3' high gain antenna pointed at the tower, or get in the transmission line of sight.

These guys did a 72 mile link

But then got in trouble with the FCC for using a 1 Watt amplfier and had to reduce it down to 250 Milliwats which reduced the bandwidth down to 300k

See, I knew you had to be careful or you might get the FCC involved :D

Buzz...Dosen't count as it uses a mind blowing 6 wats of pure power :D The FCC will have to do something about that, woops forgot Sweden, I guess the the department of homeland security or the CIA can take them out...:evilgrin:

If you vote for me as president when I'm 35 and can legally run, I promise to make a relatively uncontrolled free airwave space. The only regulation is - non-commercial use ONLY. Any citizen can use it for private communications up to 10 watts.

Wait, I thought you were going to England, or if you were lucky enough Denmark. Can't run for President with your posted plans.
