Re: Voice spectrum swapped for LTE

Let us put Liam's post in context:

Issue every student, high school scholar a BlackBerry (those that
can't do 3G only EDGE, read: GSM frequency) that they use for BBM and
you don't have any more voice channels available. No, having a GR 9
girl and GR 8 boy, this is not far fetched, its close to fact  today.

Oh, and you do know that there are these half rate GSM features that
cellphones have to use half the frequency/bit rate for a call which
gives more channels for the cell, but halves the call quality?

I have seen these mobile Vodacom base stations all over the Bellville
area, and I have Vodacom friends that complains about Vodacom call
quality in this area... I guess that in this Bellville area nearly
everybody (except me) have a Vodacom cell phone close to the Vodacom
TEchnoCentre :(

GSM (and all radio based stuff which isn't licensed point-to-point)
have no guarantees when you start adding and/or moving stuff around,
so if you do care about real call quality, for all their faults,
Telkom still is the benchmark!!
