• A Protocol Gateway — the protocol gateway
translates requests from the WAP protocol
stack to the WWW protocol stack (HTTP and
TCP/IP).
• Content Encoders and Decoders — the con-

compact encoded formats to reduce the size
and number of packets travelling over the
wireless data network.
GSM
Global System for Mobile Communications. GSM
is the world’s most widely-used digital mobile
phone system, now operating in over 100 coun-
tries around the world, particularly in Europe and
