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.

If you would like to learn more on this subject, you are welcome to enrol in ELEC S212 Network Programming and Design offered by the School of Science and Technology of the OUHK.
