• The WDS screen lets you set up a Wireless Distribution System, in which the 
CellPipe 7130 RG acts as a bridge with other access points (
Section 7.8 on page 
156
).
• The Advanced Setup screen lets you change the wireless mode, and make 
other advanced wireless configuration changes (
Section 7.9 on page 158
).
You don’t necessarily need to use all these screens to set up your wireless 
connection. For example, you may just want to set up a network name, a wireless 
radio channel and some security in the General screen.
7.2  What You Need to Know
Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie 
radios send and receive information over the airwaves, wireless networking 
devices exchange information with one another. A wireless networking device is 
just like a radio that lets your computer exchange information with radios 
attached to other computers. Like walkie-talkies, most wireless networking 
devices operate at radio frequency bands that are open to the public and do not 
require a license to use. However, wireless networking is different from that of 
most traditional radio communications in that there a number of wireless 
networking standards available with different methods of data encryption.
Wireless Network Construction
Wireless networks consist of wireless clients, access points and bridges. 
• A wireless client is a radio connected to a user’s computer. 
• An access point is a radio with a wired connection to a network, which can 
connect with numerous wireless clients and let them access the network. 
• A bridge is a radio that relays communications between access points and 
wireless clients, extending a network’s range. 
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or 
more wireless clients.  The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless 
clients connect to one another in order to exchange information.
Network Names
Each network must have a name, referred to as the SSID - “Service Set 
IDentifier”. The “service set” is the network, so the “service set identifier” is the
