High speed wireless?

[jon h]

Anyone got any advice....? I need to extend our network to another building 20 metres away across a road, Ideally with a gigabit link. I an looking at a point to point laser system currently costing about £5k. anyone with experience of this type of thing out there, or alternative suggestions. We will be moving big graphic files about, so plenty of bandwidth is a must.

Cheers

Hi Jon

Does it absolutely have to be full Gigabit? If not, the new breed of 802.11n routers could be a *much* cheaper solution and 20m should be no problem in terms of range. Real-world throughput is claimed at 160Mb/s. You could maybe get around 100Mb/s at 20m in open air which is pretty fast for file transfer, etc.

Take a look here for more information.

Hope this helps,

Lee.

We used 100Mb p-to-p lasers over a couple of hundred metres with no real issues. Voice and data for between 30 and 40 users but no mega large files. Also ran IP video conferencing over the link with no problems too. Only time we came a cropper was in dense fog

Only other thing to watch out for is the regualr servicing of the units - this can cost a bit but in the 3 years I was there they were reliable.

You could install multiple 802.11n networks (each a seperate physical network) & multiplex them together to create a huge pipe. This would have an in-built back up as if any of the networks failed, you would still have the remaining networks connected.

This device was created by hackers for 801.11b/g networks but you could build it yourself or get them to build one to your specifications using 802.11n and remove the hacking functionality by using WPA instead of WEP to secure all the connections.
