CHAPTER 2: WIRELESS NETWORK FUNDAMENTALS
Wireless Network Configuration
Ad-hoc Mode (Peer-to-Peer Workgroup)
The Institute of Electrical and Electronics Engineers (IEEE) standard for wireless LANs (WLANs),
802.11, offers two methods for configuring a wireless network — ad hoc and infrastructure. In an ad hoc
network, computers are brought together as needed; thus, there is no structure or fixed points to the
network — each node can generally communicate with any other node. There is no access point involved
in this configuration. It enables you to quickly set up a small wireless workgroup and allows workgroup
members to exchange data or share printers as supported by Microsoft Networking in the various
Windows operating systems. Some vendors also refer to ad hoc networking as Peer-to-Peer group
networking.
In this configuration, network packets are directly sent and received by the intended transmitting and
receiving stations. As long as the stations are within range of one another, this is the easiest and least
expansive way to set up a wireless network.
To set up an ad hoc workgroup operating with standard protocols, do the following:

To set up an ad hoc workgroup operating with standard protocols, do the following:
y
Set all stations to connect in Ad-hoc mode (or Peer-to-Peer workgroup mode).
y
Set all stations to use the same network name (or SS ID).
y
Set all stations to use no WEP encryption key or an identical WEP encryption key.
y
Set all stations to use the same wireless channel for communication.
Infrastructure Mode
With a wireless access point, you can put the wireless LAN into the infrastructure mode. It provides
wireless connectivity to multiple wireless network devices within a fixed range or area of coverage,
interacting with a wireless nodes via an antenna.
In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet data,
acting as a bridge between the wired LAN and wireless clients. Connecting multiple access points via a
wired Ethernet backbone can further extend the wireless network coverage. As a mobile computing device
moves out of the range of one access point, it moves into the range of another. As a result, wireless clients
can freely roam from one Access Point domain to another and still maintain seamless network connection.

y
Set up wireless channels used by individual access point. (It is not necessary to set channels on the
stations as the stations will automatically scan through all channels for the nearest access point.)
