WISP is an acronym which stands for Wireless Internet Service Provider, an ISP that allows subscribers to connect to a server at designated hot spots (access points) using a wireless connection (such as WiFi). These can be Wi-Fi hotspots or an operator with a Wi-Fi based network infrastructure. Often they offer additional services, like location based content, Virtual Private Networking and Voice over IP.

WiSpring is an example of a WISP. WiSpring's fixed wireless network provides Internet access to the un-served and under-served communities beyond the reach of existing cable and telecommunications infrastructure. They don't use satellites, and you won't need a second phone line in your home. Their network uses a small antenna placed at your home or office. The antenna is aimed toward one of WiSpring's towers, which sends and recieves data: Internet, email, video, music, etc. The nature of their technology eliminates the weather-related service outages and poor latencies that are characteristic of satellite internet systems. People ask if this is WiFi. The simple answer is no. WiFi has a typical range of 150-300 feet, whereas WiSpring is community-wide, and covers many miles.
