Long Range WiFi
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 transmission power, antenna type, the location they’re used in, and its environment. A typical wireless router in an indoor point-to-multipoint arrangement using 802.11n and a stock antenna might have a range of 30 metres but will not be able to reach much further at any resonable speed.
Outdoor point-to-point arrangements, through use of directional antennas, can be extended with many kilometers between stations. As long as line-of-sight is achievable from high up a mast, building or even a mountain, you will be able to achieve 10km hops and more.
