High Speed Circuit Switched Data (HSCSD)
HSCSD is an enchanced GSM network capability offered by some network operators. It enables
circuit switched data connections to run at a higher data speed, using more than one wireless
‘timeslot’ for the data transmission. This is ideal for providing a faster connection to existing
corporate or ISP dial-up facilities. The preferred connection speed is selected when you define
the connection using the Connection Wizard.
General Packet Radio Service (GPRS)
GPRS is a new network connection which provides “always on” mobility. The connection set up
is fast and, once connected, applications may send and receive data whenever required. In today’s
GPRS networks, the GC79 receives data at speeds up to 53.6 kbps and transmits at speeds up
to 26.8 kbps.
Short Message Service (SMS)
The PC can send and receive SMS text messages using the SMS Messages screen in the GC79
Manager, see GC79 Manager SMS Messages Screen on page 48, for more details.
