Glossary

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. 

Satellite broadband 

A wireless high-speed Internet connection provided by satellites. Some satellite broadband connections are 
two-way—up and down. Others are one-way, with the satellite providing a high-speed downlink and then 
using a dial-up telephone connection or other land-based system for the uplink to the Internet. 

Server 

A computer that provides its resources to other computers and devices on a network. These include print 
servers, Internet servers and data servers. A server can also be combined with a hub or router.
