APN

Access Point Name. Provides routing information for GPRS. The APN consists of two parts; the Network ID, which identifies the external service requested by a user of the GPRS service, and the Operator ID, which specifies routing information.

bps

Bits per second. Rate of data flow.

Broadband

High-capacity high-speed, transmission channel with a wider bandwidth than conventional copper telephone lines. Broadband channels can carry video, voice, and data simultaneously.

CDMA

Code Division Multiple Access. A digital cellular technology using spread-spectrum techniques that is the common platform for 3G technologies.

CHAP

Challenge Handshake Authentication Protocol. A method of user authentication that uses random values.

EDGE

Enhanced Data GSM Environment OR Enhanced Data for Global Evolution. EDGE is an enhanced version of GPRS that enables the delivery of multimedia and other broadband applications to mobile devices. It is designed to deliver data downloads at rates up to 237kbps and is considered an evolutionary step to 3G/UMTS.

Firewall

A hardware or software boundary that protects a network or single notebook from unwanted outside traffic.

GPRS

General Packet Radio Service. GPRS is a packet-based broadband service with download speeds up to 86kbps. GPRS is considered an evolutionary step to more advanced technologies such as EDGE and WCDMA.

GPS

Global Positioning System. A satellite-based navigation system that indicates your current position, including latitude, longitude, and altitude.

HSDPA

High Speed Downlink Packet Access. HSDPA is an enhanced version of WCDMA that supports broadband connections with download speeds up to 3.6 Mbps. This enhanced 3G technology enables the download of high-bandwidth multimedia files, high resolution graphics, and other complex files, and viewing email attachments at broadband-like speeds.

ISP

Internet Service Provider. Also referred to as the service carrier, an ISP provides Internet connection service.

IP

Internet Protocol. The mechanism by which packets are routed between computers on a network.

Kbps

Kilobits (1024 bits) per second � rate of data flow.

LAN

Local Area Network. A data network confined to limited area with moderate to high data rates.

Mbps

Megabits (1,048,576 bits) per second - rate of data flow

NDIS

Network Driver Interface Specification. A Windows device driver interface that enables support for multiple network protocols.

NMEA

National Marine Electronics Association. A data specification for communication between marine electronics using GPS receivers.

PAP

Password Authentication Protocol. A method of user authentication using user names and passwords.

PIN Code

Personal Identity Number. A code that is linked to your SIM card for security. This four-digit code gives you access to the SIM card and allows you to access your service provider�s network.

Proxy

A firewall mechanism that replaces the IP address of a host on the internal (protected) network with its own IP address for all traffic passing through it.

PUK Code

Pin Unlock Code. PUK is the code required to unlock a GSM SIM card that has disabled itself after an incorrect PIN code was entered three times in a row. If an incorrect PUK code is entered 5 to 10 times, the SIM card will permanently block (disable) itself.

SMS

Short Messaging Service. Short text messages of no more than 160 characters sent and received by broadband devices.

TCP/IP

Transmission Control Protocol/Internet Protocol. A protocol for communicating over the Internet.

UMTS

Universal Mobile Telecommunications System. A third generation (3G) mobile communications technology that offers peak data transmission speeds of up to 2 megabits per second (Mbps). UMTS uses WCDMA technology, and the two terms are often used interchangeably with each other.
