wireless broadband High-speed wireless transmission of data. However, the "high" in high-speed is always a changing number. In the past, wireless broadband started at 250 Kbps for cellular carriers, whereas land-based broadband started at 1.5 Mbps (T1 rates). Subsequent 3G wireless systems have exceeded T1 rates, and wireless LANs (Wi-Fi) have long passed that benchmark. In any event, wireless systems are a little to a lot slower than land-based, wireline networks. For example, high-speed, wired LANs have reached 10 Gbps.Wireless Local and Wireless Wide Area Wireless broadband falls into local and wide area categories. Wireless local area networks (WLANs), namely 802.11 Wi-Fi networks, transmit at very high-speed, but Wi-Fi coverage areas (hotspots) are sporadic and span only a couple hundred feet. In contrast, wireless wide area networks (WWANs), provided by the cellular industry's EDGE and 3G (EV-DO and HSPA) technologies, are much slower. However, cell towers span several miles and provide contiguous data service just like they do voice. See 802.11, 802.16, cellular generations and broadband. Want to thank TFD for its existence?
