ABSTRACT
This article presents information regarding the development of wireless broadband. For much of its history, wireless has been concerned with long range and limited throughput-examples include shortwave radio, broadcasting, wireless Morse code and analog voice. However, as it is known from what's happened in wired networks over the past 15 years, today's theme is broadband-higher data rates, capable of carrying many simultaneous interactions, increasingly in support of voice and video applications. Indeed, wireless technologies have made major progress in this quest for broadband. While broadband is the goal, one would be remiss if one didn't mention short-range, low-bandwidth technologies like RFID, Zigbee, Bluetooth and near-field communications. The local area network (LAN) has become the dominant metaphor in networks of all forms. Indeed, the "local" in LAN has become increasingly inappropriate as macro-scale networks adopt many LAN characteristics, minus the distance limitations. Wireless LANs (WLANs), however, do indeed have distance limitations, but now provide wire-like connectivity for the last few meters off the LAN backbone. INSET: Software-Defined Radio.
