Most alarm and security systems need that kind of frequency in order to work properly, and I think the TI will provide just that. It will be interesting to see whether this new product will do well for the years to come.

Hi, I am Erling Simensen from TIís low-power RF group. Development kits for the CC112x family (as shown at Embedded World 2011, Nuremberg) will be available on ti.com by the end of June. Pricing for CC1120 will be $2.85 in 1k quantity. A similar device with reduced RF performance and cost is the CC1101 available here: http://focus.ti.com/docs/prod/folders/print/cc1101.html.
