1. Overview
1.1 Introduction
The GSM/GPRS wireless network combines the world’s leading wireless standard—the
Global System for Mobile Communications (GSM)—with fast, packet-switched access to
data networks such as the Internet. Providing this fast access is the General Packet
Radio Service (GPRS).
SG6001 is designed to operate in GSM/GPRS networks. Two data services are
available in the GSM/GPRS networks: GPRS, a packet switched connection, and SMS,
a short message service.
GPRS
GPRS is an IP-based service that offers fast, packet-switched access to data networks
such as the Internet. It is a mobile service that improves the peak-time capacity of a
GSM network. GPRS gives packet-switched access over GSM to external data
networks with high peak transfer capacity. The main objective of GPRS is to offer
access to standard data networks such as TCP/IP. GPRS is a non-voice service
designed specifically for transmitting data. It breaks data messages into separate
packets for transmission from the mobile device and sends them to destinations in an
external network.
Most Internet-based application or service will run on GPRS. GPRS offers peak
throughputs of 40 Kbps (53.6 Kbps raw) because GPRS capacity is shared among
active users in the same coverage area, actual throughputs may vary.
SG6001 GPRS Serial Server
SG6001 GPRS Serial Server is a stand-alone device, enabling various kinds of legacy
devices with simple I/O and proprietary serial protocols to communicate over
GSM/GPRS network and the Internet easily and freely.
In addition to the standard GSM/GPRS modem functionality; SG6001 is supplied with
easy-to-use APIs and GPRS Gateway Software that streamline application development
process, freeing system integrators from dealing with complex communication protocols
of GPRS and the Internet.
