Wireless - connect 2 networks in 2 separate buildings

Hi there,

I have two networks located on two different buildings about 20 metres apart.  I would like to connect both the networks together using wireless technology.  it doesn't have to be high speed, just good enough for normal office work (small file sharing, a bit of printing, etc.)  both the office are within line-of-sight of each other.

how much would that cost roughly in USD?  can somebody recommend some devices? what i normally see are wireless hub + wireless NICs which is not what i need, right?

btw, what is the exact term for what i'm trying to do?

thanks.

Actually you would be looking at wireless bridges and accessories to accomplish your goals. 80211.b is well populated with companies and available equipment.  The newer standard of 802.11a is firming up in the market place and should be stronger by 3rd to 4th quarter of this year.

As to names well there are almost as many of those as there are Jones's.  But, a few names that come to mind are Proxim (premium but worth it), RadioLan (have seen some good reviews), Symbol Technologies, Cisco, Agere, Linksys and others. And prices as you can expect are all over the board from say 400 to 2500.

Also those prices don't always include any need antenna which can add another 300 or more depending on design etc.  However since your just talking the short distance you are I wouldn't expect much of an up charge for this component.

Try searching wireless bridge at say either www.networkcomputing.com or www.nwfusion.com to get a feel for some of the articles written and testing done.

Also there will be much literature put out in the next few weeks about this subject as results from the last week's  NetWorld+InterOp 2002 hit the streets.

ITsy is correct. To add just a bit more info, 802.11b is a 2.4ghz frequency and that has been the standard for wireless up until the intruduction of the 5ghz frequency (the 802.11a). This new frequency will be less crowded so you'll have less interference (higher-end cordless phones and microwaves, to name a few, run 2.4ghz also) which you will need going indoors/outdoors/indoors. The thing is that you'll have to wait because not everyone is on the 5ghz bandwagon yet. There is more info and products coming towards the end of the year like ITsy comments.
You can set up your connection now if you need it asap by using the following setup:
access point linked by ethernet to a router(in turn connected to that building's network), that is in turn connected in a "wireless bridge" to a second access point also connected by ethernet to a second router(connected to the second building's network). You will probably need to invest some money in after-market antennas to boost any connectivity issues you may experience.
