Glossary

Protocol

A set of rules governing the transmission of data. In order for a data transmission to work, both ends of the connection have to follow the rules of the protocol.

PSK Pre-Shared Key.

An easy-to-set-up home mode for network access allowing for manually entering of keys and pass phrases.

Public IP Address

A public IP address is a globally unique number that identifies a device on the Internet. Anyone on the Internet can connect to the device using the public address.

PUK

Personal Unblocking Key.

A secret code made up of 8 to 10 digits. The PUK is used to reativate a SIM card that has been blocked.

Roaming

The movement between microcells in a radio network. Roaming service is used to provide network access independent of where the user resides and what service provider that is running the network.

Routing

The forwarding of data between a local network and the Internet on the most efficient route, based on the data’s destination IP address and current network conditions. A device that performs routing is called a router.

RSSI

Received Signal Strength Indicator.

The RSSI is an indicator of the strength of the received radio signal.

SIM

Subscriber Identity Module.

The “smart card” required by all mobile customers to operate their phones. Carries authentication, billing and information about the individual subscriber, as well as address book and other personalized information.

SSID

Service Set Identifier.

A unique network name that differentiates one wireless device from another. Wireless PCs configured with the same SSID can access the same network.

Subnet

A portion of a network. The subnet is distinguished from the larger network by a subnet mask that selects some of the computers of the network and excludes all others. The subnet’s devices remain physically connected to the rest of the network, but they are treated as though they were on a separate network.

Subnet mask

A mask that defines a subnet. See also Network mask.

Switching

Routing data traffic by setting up temporary connections between two or more network points. This will take the data toward its intended destination.

TCP

Transmission Control Protocol.

See TCP/IP.
