By focusing the radio signal using a directional antenna (where allowed by regulations), 802.11 can operate reliably over a distance of many km(miles), although the know-how’s line-of-sight necessities hamper connectivity in areas with hilly or heavily foliated terrain. Asynchronous Transfer Mode (ATM) and Frame Relay are wide-space networking standards that can be utilized to offer Internet entry instantly or as constructing blocks of other access applied sciences.

An alternative is to mix a set access network, typically XDSL, with a wireless community, usually LTE. The Broadband Forum has standardised an architecture for such Hybrid Access Networks. Local Multipoint Distribution Service (LMDS) is a broadband wireless access know-how that makes use of microwave signals working between 26 GHz and 29 GHz. Originally designed for digital television transmission (DTV), it is conceived as a hard and fast wireless, level-to-multipoint know-how for utilization within the final mile. Distance is typically limited to about 1.5 miles (2.4 km), however links of up to 5 miles (eight km) from the base station are attainable in some circumstances.
