All wireless users share the radio circuit, so it reacts like a single LAN segment. That means too many users will result in high collisions and slow network response. Another issue is the theoretical bandwidth as opposed to the usable bandwidth. The usable bandwidth is what the users actually see. There are several published documents that say you should expect only about 60 percent of the theoretical bandwidth in actual use.
Wireless networks can support a limited number of users.
Be sure to check the system being considered. Some are as limited as 30 users, but most will support several times that number. The great thing about wireless networking, whether linking segments or establishing a wireless segment, is that it looks like standard Ethernet to the computers. No special software or protocols need to be installed to support wireless networks. Wireless Applications Wireless applications that are supported by Web cell phones or hand-held devices using wireless connections do not have the screen real estate or the communications bandwidth to work conveniently with typical Web pages.
