Tero's wet dream - (It's getting awfully sticky in here...)
"The launch of 2.5G general packet radio services systems is inevitably going to be an ugly spectacle, involving nasty spats over the lack of interoperability among different network/phone vendors. By next summer, fine-tuned models will start demonstrating the true potential of 2.5G. Then, we have about a year before 3G starts arriving in markets outside of Japan. At that point, the data transmission speed of color-display GPRS phones will be near 100 kbps. That's when we see how well the expensive, geographically limited 3G handsets will stack up against their ugly sisters.

"GPRS claims to offer data rates up to 115 kbps. But this requires bonding together eight adjacent power hungry (as much as 20x the power consumption of CDMA) channels, and pumping as much as 5W through the handset, not likely to have positive effects on battery life, the phone, or the facial complexion of the user. In practice GPRS data rates will probably top out at about 56k, and typically function at half or a quarter that rate."

"...We have known for ages about these
limitations," says Rainer Lischetzki of phone
maker Motorola. According to Lischetzki, "The realistic
maximum rates we can get from GPRS are 64 kbps
into the handset and 30 kbps out." Privately, a BT
Cellnet engineer was even more conservative,
promising a best case scenario of 10 kbps
transmission and 40 kbps reception..."
