A: Two years ago, WLAN (wireless local area network) technology had not caught on yet. At the time, a wireless information network that could conveniently transmit large amounts of information wasn't even on the horizon. Today, thanks to WLAN and WiMAX (Worldwide Interoperability for Microwave Access), a basic wireless network has already taken shape.
