of MCS-2, MCS-5 and MCS-7; and family C consists of MCS-1 and MCS-4. The advantage of
grouping the families together in this way is that if a block transmitted in one of the coding
schemes is not acknowledged, then it can be sent as two blocks with a coding scheme in the same
family. For example, if a block transmitted using MCS-7 is corrupted, then it can be re-sent as
two blocks using MCS-5 or four using MCS-2.
Operation
The overall operation of an EDGE network is virtually identical to that of GPRS. The same core
network components are used, as it is a migration from one to the next allowing higher data rates.
In fact, the differences occur at the air interface. Here, the new scheme sends data faster and is
more adaptive in terms of the modulation ...
