Introduction to Wireless
Wireless technology is one of the fastest growing segments of the communications industry. Wireless technology makes our lives faster and more mobile and it’s only a matter of time before wireless is used in some way by most businesses, fundamentally changing the way that employees, customers, and suppliers interact. The common wireless networks of today originated from many evolutionary stages of wireless communications and telegraph and radio applications.
All wireless communication takes place over electromagnetic waves that carry signals. Wireless technology eliminates wiring among computer devices, such as PDAs and laptops, and existing networks as well as solutions for a variety of applications in homes, offices, hospitals, and public areas, where users can benefit from having mobile access to network services. This permits computer devices and users to be highly mobile while still interfacing with the Internet and corporate applications. Whether someone is within an airport, home, or office, the person can stay connected.
