Anyone know of a forum/site where I can ask some questions about 802.11b wireless implementations - I am going to get a 512k connection and share it with a mate who lives about 500m away and just want to know the best way to do it - and before anyone says anything we live in a private estate so telkom can't complain.

Not sure of any sites specifically but you should be ok at 500m however your performance will be around 1-2 Mbps given that performance degrades with distance (you only get 11 Mpbs at less than 200m). Worst case you will need to run an external antenna from the unit.
I doubt that you would have any connection at 500m, the 802.11 protocol signal strength only supports connections up to 300m max, and that is outdoors with absolutely no interference or obstacles. A typical single brick wall reduces the distance by about 35-40 meters if I remember correctly, and the signal hitting the wall at an angle decreases the range even further.
I have a friend who lives only three houses from me, around 60 meters or so, and we get no signal at his house. What you would have to do in your case is find a point on both premises that has clear line of sight to the other, and install a directional antennae. IOW, go over everything. The company Poynting (www.poynting.co.za) sells most of the equipment you would need which is:
- One antennae, 13 DBi Yagis should be sufficient, around R300 each.
- A wall mounting bracket, R50 (TV antennae brackets work well, just need a short piece of galvanised pipe)
- Sufficient amount of cable, preferably low loss cable such as Suhner Alucop, at around R30-R40 per meter (The shorter you can make this the better, don't bend cable 90 degrees)
- One female and one male N-type connectors at between R40-R100 per connector, depending on quality, and someone to crimp and connect them to the cable, or have it done at vendor if possible (Note if you crimp them incorrectly you're going to have to re-do it and waste a connector and cabling)
- One pigtail, with proprietary connector of wireless card on one side and N-Type connector on other, ranges from R100 odd to R500+ for Lucent pigtails.
- Wireless network card with connector for connecting wireless card to cabling via pigtail.
VERY IMPORTANT: If you do not seal the connections to your antennae properly, you WILL lose signal after the first bout of rain. Insulation tape is NOT sufficient, you will need proper sealants such as beautal tape (not sure of spelling).
Note this is per installation, so time this by two for both sides and you're looking at about two and a half grand minimum to get connected excluding wireless cards, then you should get full 11/54Mb/s connectivity to your friend, depending on protocol used.
There are cheaper options like going the cantenae route and using cheaper materials which I don't have alot of experience in, shouldn't be to hard though, we're busy playing around with a few designs.
This is however the most reliable and least hassle method of connecting to your friend. You could also get a wireless router at around R1500+ and an Omni-directional antennae, allowing more people to connect to you, or set up a Linux box to do it.
This is a very brief explanation so feel free to mail me if you require assistance or more information. We've done this type of thing plenty of times.
Hope this helps.

I worked on the installation of a wireless lan last year for about a two weeks. U could drom me a mail if you like and maybe i could give the answers u looking for, or i can get them from some of the guys which i know at Cisco UK. which does that work everyday.

I've got 2 directional antennas that were used to link two buildings at one stage. They look like like boxes the size of 2 packs of fags. One has an existing connector, the other is missing it's connector, so you'll need to get one crimped on.
If you think they'll be useful, drop me a mail and you can have 'em.
Oh, and anyone interesteed in trying to get two old Aironet 2Mbps wireless bridges to work (note, they are NOT 802.11 based AFAIK) is welcome to them before they go in the bin.

802.1 can do up to 40km, if you use a proper antenna, and have line of sight.

if you in cape town contact scoop. They have lots of antenae's for this purpose, you use long range wireless bridges (access points).
I know a guy who installed camerra's in his business and sends the feed home via 802.11 methods. its pretty kewl!
