This is basically Intel announcing that they are ready to compete in the mobile phone/tablet SoC market. The other vendors already had integrated wifi, 3G/LTE, but used ARM processors, locking out Intel.
I think that other vendors are using two chips by putting them inside one package. I don't think anybody else made the cpu and rf sections on the chip yet. also nice is that the rf is made using digital technology which benefits from moore's law.
