Chapter 2: Planning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped with one wireless adapter.  Computers in a wireless 
network must be configured to share the same radio channel. Several PCs equipped with wireless cards or 
adapters can communicate with one another to form an ad-hoc network.
Linksys wireless adapters also provide users access to a wired network when using an access point or wireless 
router.  An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an 
infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless 
router.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and can double the 
effective wireless transmission range for two wireless adapter PCs.  Since an access point is able to forward data 
within a network, the effective transmission range in an infrastructure network can be doubled.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your 
wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they 
both share the same channel and SSID.
Before you consider enabling roaming, choose a feasible radio channel and optimum access point position. 
Proper access point positioning combined with a clear radio signal will greatly enhance performance.
infrastructure: a wireless network that is 
bridged to a wired network via an access point.
ad-hoc: a group of wireless devices 
communicating directly with each other (peer-
to-peer) without the use of an access point.
roaming: the ability to take a wireless device 
from one access point's range to another without 
losing the connection.
ssid: your wireless network's name.
