One other hope I have is that the RF chip designers will start making
more flexible radios. Does a GSM/wifi/bluetooth/GPS phone really need
4 different RF chips and associated antennas and cabling? Using
software-radio techniques it might be possible to combine some of the
hardware.
GPS 1.5 Ghz
WIFI 2.4 Ghz
Bluetooth 2.4 Ghz
GSM-L 850 Mhz (to 900 Mhz)
GSM-H 1.8 Ghz (to 1.9Ghz)
Except for the GSM low band, all the frequencies are relatively close
to one another, certainly within a power of two of each other. Even
with the GSM low band, it is still within a factor of 3.
