Hi,

I am working on a project at the moment and am also planning to start a Wireless Broadband Internet Service, but for now I need the connectivity in 2 KM Radius only. The Equipment I am using is USR5450 Turbo Access Point. I have connected an external 8 DBi Omni Antenna with the WAP. I have order some Kensington Wifi Detector but they dont seem to work anyway so i will pass on the wifi detectors, but I cannot use it for more than 200 Meters which i still get with out the Antenna, am i doing anything wrong, I have checked the Low Loss and MSI Cables they are all fine. But for some reason the thing doesnt seem to work for me. Please advice on this any help or resources to help me start on this one. Awaiting to hear from the experts.

Thanks for all your time, help and support.

Kind Regards

If you are using 802.11b, chances are you will need a larger antenna than an 8db.  16 will get you you the kind of range you are talking about.  Also, remember that power lines and other interferrence type items will significantly shorten your range.

Most of all, you need to understand that wireless works like a game of catch.  You can have an incredible hulk on one end, but the smurf needs to be able to throw the ball back.  That is why you will have to mount an antenna (yagi's are the best as you know which direction they must point) on your customers' roofs in order to get their sending packets back to the shop.

I recommend getting a card you can hook an external antenna to on a laptop, connect a descent antenna to it, and go drive around.  Small investment for the type of money you will get in return.
