S-T
SMS
Short Message Service is a text message communication service prescribed by
the European Telecommunications Standards Institute. A single ‘short message
can contain text up to a maximum of 160 characters, and can be promptly
transmitted provided the receiving terminal is “on” and within the mobile
network transmission range. If this is not the case, the short message is stored
for later transmission when the receiving party terminal is turned on or
reenters the network range. This service is particularly popular among young
people in Europe and Japan.

access for self business or work at home. With UMTS, a SOHO transfer speed

STREAMING
One-way transmission of video and audio contents over the Internet is called

Streaming is also possible over advanced wideband wireless networks. In this
manner, it becomes possible to view a certain news program or the video clip
of a favourite singer without placing a burden on the terminal memory.
