NSN wil l implement EDGE Evolution in two steps
Step 1. Downlink Dual Carrier (DLDC) in RG10
Step 2. EGPRS-2 B(REDHOT, HUGE) in downlink and uplink inRG20

Two carriers from the same BTS
TBFs expanded over 2 carriers
Incremental redundancy betweencarriers is possible
MS may alternate between carriersin uplink
Doubled DL data rates over the whole cell area.Provided bit rates are sufficient for high quality video.

Average bit rates up to 400 kbps (2X5 slots)

Doubling of data rates in DL will be achieved
with the introduction of the 1.2 times higher
symbol rate with QPSK, 16QAM and 32QAMand turbo coding.
RED-HOT-B gains can be linked with MS
diversity or dual carrier.
Can provide over 50% improvement inspectral efficiency.
RED-HOT-B will introduce only 8 new
modulation and coding schemes.
RED-HOT-B outperforms EGPRS, thuslegacy symbol rate is needed only for
EGPRS signaling with CS-1 or sending USFs
to legacy EDGE MSs.
Trade-off between coverage and adjacentchannel power. EXxB DTRX HW required

Doubling of data rates in UL will be
achieved with the introduction of the 1.2
times higher symbol rate with QPSK,16QAM and 32QAM
Simulated spectral efficiency gains of
HUGE-B exceed 50%.
HUGE will use 8 new modulation andcoding schemes.
HUGE-B outperforms EGPRS, thus legacy
symbol rate is needed only for EGPRS
signaling with CS-1 Camera phones linked with new video
sharing services will likely increase bit rate
demand in uplink.
Substantial gain to end-user experience,thus revenue increase is expected.
