Technology Issues

The concept of the WLAN has changed significantly in just the past few
years alone. At first, wireless networks were used only to transfer small
amounts of information from one department to another. There was no
unified standard, so hardware was very slow and proprietary—there
was no compatibility between different vendors.
Wi-Fi, now a standard most commonly represented in 802.11 networks,
has increased in speed and in versatility. Information is now
ported throughout large areas and can bring computing resources to the production areas of a company where no wireless infrastructure exists
or can be implemented.

The technology for the WLAN is most commonly represented between
a client and an access point, and there are a number of network setups
possible.
