Mobile Internet technology jargon buster

Just
as we’d managed to get our heads around desktop Internet technology, there is a
whole set of mobile terms to get used to. WAP, or wireless application protocol,

phrases:

3G
The third generation of mobile communications technology, which promises
high-speed data transfer and multimedia capabilities on mobile phones and other
handheld devices such as palmtop computers.

GPRS
General Packet Radio Services. This provides an "always-on"
connection and allows transmission of up to 56kbps, equal to an average PC’s
modem. The technology is aimed mainly at GSM-based, 2G phones. GSM, which stands
for Global System for Mobile phones, is currently the most well-used digital
communication system.
