No wires, cords or plugs required. Wi-fi is all the buzz these days. From airports to the corner coffee shop, it's getting easier to access the internet, and all you need is your laptop. Now a few New Hampshire communities are designing "hot spots" or areas of free internet access right in the middle of downtown. We'll talk about how wi-fi works, why everyone wants a piece of it, and can it live up to it's repuation. Mike's guest is Glenn Fleishman, co-author of "The Wireless Networking Starter Kit: The Practical Guide to Wi-Fi Networks for Windows and MacIntosh" and editor of the daily Web log Wi-Fi Networking News. We'll also hear from Chris Williams, vice president of economic development at Manchester's Chamber of Commerce and a spokesperson from Portsmouth's eCoast Technology Roundtable.
