EDGE, a new radio interface technology with enhanced modulation, increases HSCSD
and GPRS data rates by up to threefold.
requires users to dial-up, unlike the permanent GPRS connection to the Internet.
The Nokia launch was a PC card-format HSCSD
terminal, that aggregates to 28.8Kbps each way, or asymmetrically to give 43.2Kbps downstream and 14.4Kbps upstream.
FoneStar EX, for use with Microsoft Exchange, runs over fixed line, PSTN, GSM, HSCSD
, GPRS, CDMA and UMTS networks.
The third new product is the Nokia 30 GSM Connectivity Terminal, which can be installed within a remote device, such as a vending machine or an elevator, and offers GPRS, SMS, USSD, HSCSD
data connection and audio over EGSM900/1800 networks.
Based on ImageCom's Remote Video Expertise solution, the new product enables both moving and still images to be sent across standard mobile networks, including GSM, GPRS and HSCSD
New figures released by the GSM Association show that 28 GSM networks have so far implemented High Speed Circuit Switched Data (HSCSD
), a technology that enables network subscribers to transmit and receive data at rates of up to four times the standard GSM rate of transmission.
The ISP has installed Nortel's CVX 1800 and CVX 600 multiservice access switches, which support services based on the WAP, HSCSD
(High Speed Circuit Switched Data) and GSM standards as well as terrestrial access technologies.
Targeted primarily for mobile professionals, the phone enables an always-on WAP connection, supports HSCSD
(High Speed Circuit Switched Data) for flexible data connections and incorporates WTAI (Wireless Telephony Application Interface) Public Library, a feature that enables users to make phone calls from WAP sites.
Belonging to Nokia's Classic category models, the phone supports both high speed circuit switched data (HSCSD
) with data speed of up to 43.2Kb/s and wireless application protocol (WAP).
