Making a wireless transceiver

Hello,
I am interested in making my own wireless transceiver, I wish to communicate via radio waves, rather than light, and would desire a range of 100m. Has anyone managed to create a similar type device? I will use it to serial communicate between two Arduinos.

I do not wish to use an X-bee, and would like to create the transceiver myself.

Many thanks.

NRF24L01 would work with it. It works on 2.4Ghz. Here is the link for How to : http://maniacbug.wordpress.com/2011/11/02/getting-started-rf24/

This is the link for library.

You can use Antenna to extend the range.
Hope this helps.

Its not generally viable to build your own radio tranceivers.
You need specialised test gear that most people dont have, and its far easier to simply buy
the assembled radios.
