Note: The 54-Mbit/s maximum speed of 802.11g is obtained only when the network contains other 802.11g-based devices. Users who mix 802.11b devices in that network will see a maximum throughput value of only 22 Mbit/s.

•The 802.1x standard defines the method of encapsulating EAPs over wired or wireless Ethernet networks. This standard does not define any specific security protocol, but is based on EAP types documented and ratified by the Internet Engineering Task Force (IETF).

Additional Security Solutions

Personal firewalls are the best way to protect your computer-related devices and wireless network. A firewall keeps computer hackers out and your sensitive data in; it acts as a barrier through which all information passes between the computer and the network. Personal firewalls monitor all incoming and outgoing traffic on your computer, including external systems.

Firewalls look at this data and make an access decision based on predetermined access rules. A firewall can give you the needed tools to protect your sensitive information while you’re communicating across public networks. You have an option of selecting what information you want to protect, such as credit card numbers or passwords.

Personal firewalls can also prevent Web servers from getting access to sensitive data, and they can block Java applets and ActiveX controls. These Internet tools can endanger computer security. Firewalls can provide you with various helpful security needs for your computer hardware and software.

Personal firewalls are also available for mobile devices, such as Zone Alarm Personal Edition from Zone Labs, Inc. To download a free copy of this software on to your personal computer or notebook, go to www.zonelabs.com for more information.
