Intel(R) PRO/Wireless LAN Mini PCI Adapter User's Guide This document provides information for the following wireless devices: ● ● Intel(R) PRO/Wireless LAN 7100 3B Mini PCI Adapter, operating at 5 GHz Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter, operating at 2.4 GHz These wireless adapters operate with high-capacity networks using multiple access points within large or small environments.
Back to Contents Page About Wireless LAN Technology ● ● ● ● ● ● Choosing a WLAN Configuring a WLAN Identifying a WLAN Surveying the Site of Your WLAN Factors Affecting Range Stronger Security A wireless network connects computers without using network cables. Computers use radio communications to send data between each other. You can communicate directly with other wireless computers, or connect to an existing network through a wireless access point.
Configuring a Wireless LAN There are three basic components that must be configured for a wireless LAN to operate properly: ● ● ● Network Name—Each wireless network uses a unique Network Name to identify the network. This name is called the Service Set Identifier (SSID). When you set up your wireless adapter, you specify the SSID. If you want to connect to an existing network, you must use the name for that network.
Conducting a site survey for your wireless LAN is the most crucial step in the process of setting up a wireless network. It greatly reduces the amount of troubleshooting you will have to do once you have the wireless LAN set up and ready for connection testing. To conduct a site survey, you will need the following tools: ● ● ● An access point (or laptop computer) that is set up to be the transmitter. It should be mounted near and at the same height as the designated location of your wireless LAN.
Stronger Security Although wireless networks are easy to use, the main issue lies with security. Even if you enable the security settings defined in the 802.11b standard, as well as the security settings of your hardware, your network is still vulnerable. There are a few things you can do to make it more difficult for outsiders to access your network: ● ● ● ● ● ● Change the default network name of your WLAN. Every manufacturer's default settings are public knowledge.
Back to Contents Page What is a Site Survey? A site survey is an in-depth examination and analysis of a proposed wireless LAN site. The purpose of a site survey is to determine the number of access points needed, the types of antennas needed, and the best placement for those access points and antennas. Although the goal of a site survey is simple, the means of arriving at that goal are not.
3. 4. through and inventory. Conduct a physical walk-through and inventory. The primary purpose of the physical walk-through is to document any items or materials near a proposed device location that may interfere with reception or transmission and affect network performance. Document stock and inventory levels, current environmental conditions and any materials that may interfere with the wireless LAN. Measure the radio frequency transmissions.

Range is highly dependent on the physical environment. In a line-of-sight location, with elevated and calibrated antennas, range predictions are quite accurate. This is not true in a “typical” office building, where the walls may be simple drywall (which is almost transparent to microwaves), or could be plaster with metal underneath. Most sites are somewhere between these two extremes, and consist of a mixture of surfaces.

Back to Contents Page Setting Up WEP Encryption and Authentication Wired Equivalent Privacy (WEP) encryption and shared authentication provides protect for your data on the network. WEP uses an encryption key to encrypt data before transmitting it. Only computers using the same encryption key can access the network or decrypt the encrypted data transmitted by other computers. Authentication provides an additional validation process from the adapter to the access point.
Back to Contents Page Virtual Private Networks and Encryption A Virtual Private Network (VPN) allows remote users who belong to a private network (Intel network) to communicate freely and securely through a public network, such as the Internet. Many companies, including Intel, now use hardware and software VPN solutions that employees with high-speed Internet connections use to establish a secure tunnel between home and the corporate network.
To tighten security measures a system administrator can configure remote access dial-in settings to define a group profile such that all users who are assigned to that profile are required to authenticate by using the Extensible Authentication Protocol (EAP) and encrypt their data by using strong (128-bit) data encryption. By assigning a user to the group profile, these security measures are automatically required when anyone in that group profile connects to the remote access server.

Direct-Sequence Spread Spectrum (DSSS) and Frequency-Hop Spread Spectrum (FHSS): Two incompatible technologies used in radio transmission. E Extensible Authentication Protocol (EAP): An authentication protocol that supports multiple authentication methods, such as Kerberos, passwords, or smart cards. Cisco's authentication protocol, LEAP, is based on EAP, an extension to PPP (Point-to-Point Protocol). Encryption: Scrambling data so that only the authorized recipient can read it.
K Kerberos: An authentication system enabling protected communication over an open network using a unique key called a ticket. M Media Access Control (MAC) Address: A hardwired address applied at the factory. It uniquely identifies network hardware, such as a wireless PC Card, on a LAN or WAN. Microcell: A bounded physical space in which a number of wireless devices can communicate.
RC4: An encryption algorithm designed at RSA Laboratories; specifically, a stream cipher of pseudo-random bytes that is used in WEP encryption. Remote Authentication Dial-In User Service (RAID): An authentication and accounting system that verifies users' credentials and grants access to requested resources. Roaming: Movement of a wireless node between two microcells. Roaming usually occurs in infrastructure networks built around multiple access points.
eavesdropping. Use of the 128 bit option at all possible times is recommended. Remember that 802.11 devices transmit (broadcast) in all directions, and that it is possible, with very complex software, to copy and decode WEP transmissions. The task is not trivial, but it is possible. If your data is extremely sensitive, you should consider some form of secondary protection, such as strong passwords and an additional level of encryption. Suitable software packages are available from reputable suppliers.
