Hello everybody,

I need to build the cost less point to point wireless device, this device is going to be design to transmit information from one pc to another about 50 meters one to another, I'm thinking to use bluetooth, but i have not expirience, seems to me the easy way and chiper, I would like to bluid my self to get some expirience.

Please if any knows where I can found this circuit or information let me know.

I recommend you use some sort of prepackaged device. That way you don't have to think about any of the communications that will go into it. There is a website called RF linx, that make some very good prepackaged devices that operate in the ISM (Industrial, Scientific, and Medical band, its non-liscense band) band.

They sell devices that will do FSK type modulation for digital data, or some of the more common analog schemes such as FM and AM.

I recommend you start there.

 

Check out the last 2 issues of siliconchip as they are doing an article on setting up wireless on computers. The article goes right through all the basics thru to more advanced ways and they also give a link to a wireless book available which is supposed to be the bible on the subject

Hope this helps

Cheers Bryan

Bluetooth is not all that quick the data rate may be unsuitable for large file transfers
