In this article, the author presents the latest wireless equipments available in market. For starters, wireless networks offer mobility and flexibility: users of laptops, PDAs, tablet PCs, and wireless Voice over IP telephones can move freely about campus while staying connected to the Internet. There are two kinds of wireless networks: ad-hoc, or peer-to-peer networks, and wireless local area networks (WLAN). With ad-hoc networks, each computer on the network has its own wireless networking interface card and can communicate directly with other wireless-enabled computers. The WLAN approach sets up a network connection that revolves around an access point. Most access points can support as many as 30 computers concurrently, and each device services a finite range. Since the newest Microsoft and Apple operating systems automatically search for active access points, one shouldn't have to do much more than plug in an access point for it to work (older operating systems can be retrofitted to work with wireless, too, but newer operating systems work best). Wireless networking poses potential security issues because intruders don't need physical access to the traditional wired network to gain access to data.
