do you think the wavelengths used by phones are going to work through space and the atmosphere, are they focused on short length transmissions (higher freqs). The answer appears to be yes ;-)
wavelength is just a requirement for an antenna which doesn't need to be shielded. i wasn't specifically saying use COTS phone chipsets, but the fact that the miniaturization is now possible. however, the little helicopter on Mars running Snapdragon chip (irc?) shows that COTS is possible
