Hmm, 10Mips per GSM time slot,10kbps, 200Mips 3G hardware... 20 timeslots??
and then a little EDGE..
What about 12,000Mips???

Next-generation phones will need to support multiple bands (e.g., 2000 MHz, 1800 MHz), multiple modes (WCDMA, GSM) and multiple modulation techniques (GMSK, QPSK), and handle multiple time slots with GPRS and EDGE in order to increase the data rate.
Each of these functions places an additional burden on the DSPs (yes, there is more than one), the microprocessor, plus about 1 million additional ASIC gates for WCDMA processing.3 Motorola and Nokia both estimate that the radio channel processing requirements alone for WCDMA could reach 200 MIPS and that total MIPS requirements could reach as high as 12,000 MIPS. Although we have not seen any published numbers for MIPS, we believe similar processing power will be required for CDMA2000 (EV/DV).

Footprint. Ask any corporation or individual looking to lease property and they will tell you that property rental rates are at a premium, when and if they can find a location that satisfies their needs. Wireless operators face the same predicament. As they roll out their 3G networks, operators will require new locations where they can install their equipment (sometimes sharing a location with another operator).
In many instances, the amount of available floor space will be limited, and in almost all cases it will cost them a king’s ransom. Thus, operators demand equipment that is compact and that can fit in a small place–in other words, the equipment needs a small footprint.

It is kind of not by accident 3G runs on those little 2-3GHz things, nor that
it takes a mature 2G network to continue. |
