In this module you looked into a number of fundamental concepts and issues surrounding wireless LAN technologies.
We began by discussing the wireless LAN technologies that fall under the IEEE 802.11 series, including 802.11 a, b, g and, the latest member, n. After that, we covered Bluetooth and Infrared (IR), which are in common use for connecting peripherals to the main computer unit.
Next was a topic concerned with wireless LAN design. We concluded this part with a lab aimed at setting up an ad hoc wireless network. The Internet has become a mainstream use of the wireless network technologies. In addition to Wi-Fi, we also discussed WiMAX, an upcoming wireless broadband access technology, and made a brief note of the local development of the wireless broadband access service provisioning.
You then learned how network security is a very important topic that can’t be separated from wireless communications, simply because of the plain fact that a signal transmitted over the air can be intercepted by anyone, including those with malicious intentions.
