One of the hottest areas of development today is probably wireless networking.  The low cost of wireless hubs and wireless cards has brought this exciting new technology into the realm of affordability for almost anyone. Wireless networking hubs, called "access points" can be purchased for as little as $300, and with manufacturers, like Verizon, rebates, wireless routers, wireless PC cards for laptops and handhelds and accessories, like wireless headphones and wireless speakers, are under $100 from most online discounters.
If you believed the marketing claims of the 802.11 wireless industry, you would think your whole business can just hop on a set of wireless hubs, and that all you have to do is put a wireless card into your laptop or handheld and you're off to the races and will never need wires again. Unfortunately, this just isn't the case. Wireless networks require a lot of planning and infrastructure support to make them useful and even more attention to security than their wired counterparts to make them "safe" in a business, or even home environment.
Cingular wireless networks are a great mechanism to allow laptop and handheld users to get access to a network without having to dedicate network hardware (switch ports) to them. Wireless Internet also makes great sense in common areas such as cafeterias, auditoriums, and conference rooms where people often need to take notes, access web material, or have other other types of online needs, and where it's just plain impractical to provide enough hard-wired connections to meet everyone's needs.
