Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [ 1 ]
WokFi gains are typically 10+ dB, [2] with range boosts, thus can be 16-32 times over the antenna of a bare USB adapter. Ranges (LoS) are typically 3–5 km (2 to 3 miles), [ 3 ] although an aligned pair of similar point-to-point transceiver setups may approach 10 km (6 miles) over a clear path.
Super Wi-Fi refers to IEEE 802.11g/n/ac/ax Wi-Fi implementations over unlicensed 2.4 and 5 GHz Wi-Fi bands but with performance enhancements for antenna control, multiple path beam selection, advance control for best path, and applied intelligence for load balancing giving it bi-directional connectivity range for standard wifi enabled devices over distances of up to 1,700 meters.
Typical distances are between 50 and 250 kilometres (31 and 155 mi), though greater distances can be achieved depending on the climate, terrain, and data rate required. Typical antenna sizes range from 1.2 to 12 metres (3 ft 11 in to 39 ft 4 in) while typical amplifier sizes range from 10 W to 2 kW.
A distributed antenna system (DAS) is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level, and node installations are compact. A distributed antenna system may be ...
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
