PHY defines parameters such as data rates, modulation method, signaling parameters, transmitter/receiver

synchronization, etc. Within an actual radio implementation, the PHY corresponds to the radio front end and

baseband signal processing sections.

Plug and Play

A computer system feature that provides for automatic configuration of add-ons and peripheral devices such

as wireless PC Cards, printers, scanners and multimedia devices.

Proxy server

Used in larger companies and organizations to improve network operations and security, a proxy server is

able to prevent direct communication between two or more networks. The proxy server forwards allowable

data requests to remote servers and/or responds to data requests directly from stored remote server data

Range

The distance away from your access point that your wireless network can reach. Most Wi-Fi systems will

provide a range of a hundred feet or more. Depending on the environment and the type of antenna used,

Wi-Fi signals can have a range of up to mile

Residential gateway

A wireless device that connects multiple PCs, peripherals and the Internet on a home network. Most Wi-Fi

residential gateways provide DHCP and NAT as well.

RJ-45

Standard connectors used in Ethernet networks. Even though they look very similar to standard RJ-11

telephone connectors, RJ-45 connectors can have up to eight wires, whereas telephone connectors have only

four.

Roaming

Moving seamlessly from one AP coverage area to another with your laptop or desktop with no loss in

connectivity.

Rogue Access Point

"Rogue AP" is a term used to describe an unauthorized access point that is connected on the main home or

corporate network or operating in a stand-alone mode (in a parking lot or in a neighbor's building). Rogue

APs, by definition, are not under the management of network administrators and do not conform to network

security policies and may present a severe security risk. Ideally, it is best to have some type of WLAN

system that does not allow rogue access points to easily be added to an existing WLAN.

Router

A device that forwards data packets from one local area network (LAN) or wide area network (WAN) to

another. Based on routing tables and routing protocols, routers can read the network address in each

transmitted frame and make a decision on how to send it via the most efficient route based on traffic load,

line costs, speed, bad connections, etc.
