Technology has gone wireless in a big way, making it possible for schools to connect new computers and other devices to an existing wired network without installing costly hard-wire drops. Which wireless technologies (if any) should you implement at your school? How do you ensure data security and prevent unauthorized network logons? For answers to these questions and information about wireless networking, visit the following Internet Web sites:
CoSN Guide to Wireless LANs in K-12 Schools
This Executive Summary report by CoSN's (Consortium for School Networking) Emerging Technologies Committee focuses on the challenges and options of wireless LANs (local area networks) in 8 different school districts. The summary outlines the reasons why these districts chose to implement wireless technology. It also addresses the various wireless (802.11) standards and steps to take when designing a wireless LAN. Help others in your school or district to learn more about wireless LANs by downloading and presenting CoSN's free PowerPoint "wireless" slideshow.
The Wireless Networking Starter Kit
If you're just getting started with Wi-Fi (Wireless Fidelity), this is the site to visit for advice about implementing a wireless network. Adam Engst and Glenn Fleishman, authors of Peachpit's popular Wireless Networking Starter Kit, give visitors the option of downloading (at no charge) Chapter 17: Setting up a Gateway, plus the book's Glossary of Wireless Networking terms. You can also view an electronic version of the book's Table of Contents.

Member Question of the Week: How to Set Up a Wireless Network
C|Net Networks sends out a weekly "Community Help & How-To" electronic newsletter featuring both a "Member Question of the Week" and links to the best responses. While gathering resources for this month's Web Sightings, a reader in Panang, Malaysia posed a question about wireless networking: "I'd like to set up a wireless network connection for my home PCs (two desktops and two notebooks), all using Windows XP to share a single Internet ADSL broadband account. How should I start?" The winning response submitted by Joe M. of Chicago discussed hardware requirements (wireless routers, cards, and range expanders), installation, and various settings for the router including WEP (Wired Equivalent Privacy) encryption, firewall issues, remote access settings, Internet access settings and restricting access to the network. Dana H. of Wayland Computers in Wayland, MA submitted a second winning response to Community Newsletter: Q&A Forum, focusing on wireless standards, common problems, creating a wireless layout, network layout, preparing computers for access, setup and security settings. Both answers are very informative and reader friendly.
