You can make 2.4ghz radio on more or less the same process as the logic. With 5ghz, silicon cmos is still possible, but the power consumption will be very bad.

- baybal2 6y agoWhat I mean is that you will have to go for 2 pieces of silicon, (one for radio on a specialty process, and another for regular CMOS logic) instead of one. Even desktop wifi chips are still made in 2.4ghz only variants to save some cost in the lowest end, and for the chip priced in cents, it is completely not an option at the moment.
