To modify a John Adams quote; A capability once lost, is lost forever.Now that cell is encrypted it is not possible to listen, so it is not necessary to block out that portion of the spectrum.
(there is nothing to listen to in the blocked out segment )
I don't know how difficult it is for manufacturers to do so, but I assume it is easy with algorithms.
Members often say in the forums: "it is illegal to listen to enc communications"
I find this somewhat amusing as it is not possible to break AES 258 encryption.
So, there is a law making something illegal that is impossible to do anyway. Silly?
At the time of the ECPA cell signals were analog FM and really in the 800 MHz band only (in the US), and such a restriction made some sense, whether one agreed with it or not.
Today no cell signals in the US are analog FM, all are digital and encrypted, and the 800 MHz band is only one small band among many. Yet the regulation has never been changed to remove the frequency limitations and the regulation has not been widened to include all the cell phone bands. On one hand there is an obvious recognition that including the newer cell phone freqs as taboo in no way enhances cell privacy, but no concern on releasing the current, severely outdated and no longer applicable, restrictions.
So yeah, there is no need to restrict scanners to not receive the 800 MHz cell freqs anymore, but we are not getting that back anytime soon. And so scanner and wideband receiver makers continue to have to produce "US" versions and "outside US" versions.
