Duxbury Networking has expanded its range of modems to include Global Systems for Mobile communications (GSM) and new generation General Packet Radio Service (GPRS) offerings.
"Duxbury modems have been designed and distributed in SA since 1984," says Duxbury Networking MD, Graham Duxbury. "Our move into the wireless sector, first with GSM and now with GPRS modems is in line with the changing face of telecommunications in SA and the increasing reliance by both private and business users on this technology," he says.
GPRS-enabled networks offer `always-on`, higher capacity, Internet-based content and packet-based data services. For the users of mobile devices - such as GPRS-enabled cellphones, PDAs and notebooks - this allows them to gain access to services such as colour Internet browsing, e-mail on the move, powerful visual communications, multimedia messages and location-based services.
"Other applications for the technology - and the Duxbury modems - exist in areas such as mobile point-of-sale terminals, fleet management systems, security solutions and traffic control and navigation systems," he says.
Duxbury expects a fast uptake of GPRS technology in SA.
"With theoretical maximum speeds of around two to three times faster than dialup modem connections, GPRS offers users a communications facility which is 10 times as fast as current circuit switched data services on existing GSM networks," he says.
"More significantly, GPRS facilitates instant communications. High immediacy is a key feature for time-critical applications such as remote credit card authorisation where it would be unacceptable to keep a customer waiting for even 30 seconds."
