Apologies for pedantry and any mistakes - corrections/clarifications
are welcome.<br>
<br>
As suggested above, 4g cellular services may have required the push to
different 'frequencies'. This is the same thing that pushed analog TV
out from the lower VHF frequencies, 210 MHz for CKCO, to the UHF
frequencies so as to provide the capability for digital TV. The higher
frequencies have more capacity to carry more information, e.g. Hi-Def
TV. (ref: Shannon & Nyquist). <br>
<br>
For cellular, the transport of voice and SMS data morphed over the
tears to include data plans and now 'mobile broadband' and full motion
TV. These changes pushed cellular carriers from 700/800/900 MHz (1G?)
to 2.5 MHz (4G).<br>
<br>
From Wikipedia under 4G: "New generations have appeared about every ten
years since the first move from 1981 analog (1G) to digital (2G)
transmission in 1992. This was followed, in 2001, by 3G multi-media
support, <a title="Spread spectrum" href="x-msg://418/wiki/Spread_spectrum">spread
