EDGE increase the capacity for GPRS traffic by changing the radio
modulation. This does not change the number of voice connections that you
can provide. There are still eight time slots and each voice connection uses
one time slot (apart from half-rate codecs that only use every second
frame). Are there techniques in EDGE that use the higer capacity to increase
the quiality of half-rate vocie connections or even introduce quarter-rate
voice connections?
If EDGE only increase the capacity of GPRS traffic then the problem of
congested networks remains since most of the traffic is voice.
