Wireless means transmitting signals over invisible radio waves instead of wires. Garage door openers and television remote controls were the first wireless devices to become a part of everyday life. Now the cordless keyboard and mouse, PDAs, and digital and cellular phones are commonplace.Wireless technologies are used for things as simple as making a phone call or as complex as letting the sales force get information from an ERP application.
Once reserved for only the most mission-critical and esoteric applications, wireless communication has entered the mainstream as vendors refine the throughput, stability, security and affordability of an ever-growing range of supported wireless applications. In the wireless world, your colleagues' whereabouts become totally transparent as you remain persistently connected with one another in real-time – even if some of your colleagues are flying cross-country.
