When your Merlin XU870 has found a cellular network and has registered to it, the  LED will flash (see page 47). In this state you can send and receive SMS. However, to pass data (i.e., surf the web or check your email), you must be connected.

 

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


Highcapacity highspeed, transmission channel with a wider bandwidth than conventional copper telephone lines. Broadband channels can carry video, voice, and data simultaneously.

Connected


To connect to the cellular network you require an APN. You might also require a user name and password, depending on your service provider. Once you are connected, you can pass data (i.e., surf the web or check your email).

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 237 kbps and is considered an evolutionary step to 3G/UMTS.

Firewall


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

GPRS


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

HSDPA


High Speed Downlink Packet Access. HSDPA is an enhanced version of WCDMA that supports broadband connections with download speeds up to 7.2 Mbps. This enhanced 3G technology enables the download of highbandwidth multimedia files, high resolution graphics, and other complex files, and viewing email attachments at broadbandlike 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.

MB


Megabyte. A unit of data equal to approximately 1 million bytes.

NDIS


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

PPP


Point to Point Protocol. A method of connecting a computer to the Internet.

PIN Code


Personal Identity Number. A code that is linked to your SIM card for security. This fourdigit code gives you access to the SIM card and allows you to access your operator's network.

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 510 times, the SIM card will permanently block (disable) itself.

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.

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.

VPN


Virtual Private Network. A way to communicate through a dedicated server securely to a corporate network over the Internet.

WAN


Wide Area Network. A network which uses common carrierprovided lines. Contrasts with LAN.

WCDMA


Wideband Code Division Multiple Access. Based on the GSM technology evolution roadmap, WCDMA supports upload and download speeds up to 384kbps. WCDMA is also referred to as UMTS.

WWAN

 

Wireless Wide Area Network. A communications technology that utilizes digital mobile phone systems to access data from any location in the range of a cell tower that is connected to a dataenabled network.
