Levels of Wireless Networks
802.11b WLAN

Wireless is for everyone.
Whether your company is thinking of a wireless solution to network an entire campus or a select group of high-productivity workers within a wired organization, WLAN installations offers companies a way to improve their business operations and increase revenues. You can connect 802.11a and 802.11b products to the same wired network backbone. Since the two standards use different frequencies, you can put their access points near each other without interference.
