From: JT on 15 Jul 2005 22:26 If you are looking for a simple RF link with a roll your own protocol look at RF Monolythics. These are simple transceivers with no embedded anything. They call it Virtual Wire. Their TR1100 can handle 1Mbd. I use a slower version in my current designs. They are easy to use. Good appnotes including PCB antenna design. Good people to work with. Design assistance software. PCB gerber files. Lots of Pros. However, the one con for some is it is only a single channel only @ 916.5Mhz. I managed to work around it.

I haven't used the chipcon parts (though I have played a little with the demo board for the Frescale part). For 1 Mbd, you might check out Vishay RF Waves: http://www.rfwaves.com/item.asp?categoryid=99. They have chips or module, are supposed to be cheap and low power. They use a proprietary protocal, but claim to operate well in a mixed environment with other protocals sharing the spectrum. I haven't used them; I just found out about them a couple of days ago.
