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:
#" Set all stations to connect in Ad-hoc mode (or Peer-to-Peer workgroup mode).
#" Set all stations to use the same network name (or SS ID).
#" Set all stations to use no WEP encryption key or an identical WEP encryption key.
#" 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.
To set up an infrastructure network operating with standard protocols, do the following:
#" Set all wireless stations to connect in infrastructure mode
#" Set all stations to use the same network name (or SS ID).
#" Set all wireless access point to use the same network name ( or ESS ID).
#" Set all stations to use no WEP encryption key or an identical WEP encryption key.
#" 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.)

Service Set Identification (SS ID)
The Service Set Identification (SS ID) is a thirty-two alphanumeric character (maximum) string
identifying the wireless local area network. Some vendors refer to the SS ID as network name. For
stations to communicate with each other, all stations must be configured with the same SS ID.
A wireless LAN consisting of nodes operating in ad hoc configuration without an access point is called a
Basic Service Set (BSS). All nodes in a BSS must use the same Basic Service Set ID (BSS ID).
In an infrastructure configuration with access points, multiple BSS can be configured to form an Extended
Service Set (ESS). In this configuration, the access points are configured with the same Extended Service
Set ID (ESS ID). Wireless clients configured with the same ESS ID can freely roam from one Access
Point domain to another and still maintain seamless connection to the network
Authentication and WEP Encryption
The absence of a physical connection between nodes makes the wireless links vulnerable to information
theft. To provide certain level of security, IEEE 802.11 standard has defined two types of authentication
methods, Open System and Shared Key. Open System authentication is a null algorithm. Shared Key
authentication is an algorithm where both the transmitting node and the receiving node share an
authentication key to perform a checksum on the original message. By default, IEEE 802.11 wireless
devices operate in an open system network.
Wired Equivalent Privacy (WEP) data encryption is utilized when the wireless nodes or access points are
configured to operate in Shared Key authentication mode. There are two shared key methods implemented
in most commercially available products, forty-bit WEP data encryption and 128-bit WEP data
encryption.
The forty-bit WEP data encryption method, allows for a five-character (forty-bit) input. Additionally, 24
factory-set bits are added to the forty-bit input to generate a 64-bit encryption key. (The 24 factory-set
bits are not user configurable.) This encryption key will be used to encrypt/decrypt all data transmitted via
the wireless interface. Some vendors may refer to the forty-bit WEP data encryption as 64-bit WEP data
encryption since the actual encryption key used in the encryption process is 64 bits wide.
The 128-bit WEP data encryption method consists of 104 configurable bits. Similar to the forty-bit WEP
data encryption method, the remaining 24 bits are factory set and not user configurable. Some vendors
allow passphrases to be entered instead of the cryptic hexadecimal characters to ease encryption key entry.

Wireless Channel Selection
IEEE 802.11 wireless nodes communicate with each other using radio frequency signals in the ISM
(Industrial, Scientific, and Medical) band between 2.4Ghz and 2.5Ghz. Neighboring channels are 5Mhz
apart. However, due to spread spectrum effect of the signals, a node sending signals using a particular
channel will utilize frequency spectrum12.5Mhz above and below the center channel frequency. As a
result, two separate wireless networks using neighboring channels (for example, channel 1 and channel 2)
in the same general vicinity will interfere with each other. Applying two channels that allow the maximum
channel separation will decrease the amount of channel cross-talk, and provide a noticeable performance
increase over networks with minimal channel separationꢀꢁ

Note: The available channels supported by the wireless products in various countries are
different.
The preferred channel separation between the channels in neighboring wireless networks is 25 MHz (5
channels). This means that you can apply up to three different channels within your wireless network.
There are only 11 usable wireless channels in the United States. It is recommended that you start using
channel 1 and grow to use channel 6, and 11 when necessary.
