Wireless Internet - Wireless Internet Service Provider (WISP)

WISP is an acronym which stands for Wireless Internet Service Provider. 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.

Typically, the way that a WISP operates is to pull a large and usually expensive point to point connection to the center of the area they wish to service. From here, they will need to find some sort of elevated point in the region, such as a radio or water tower, on which to mount their equipment. On the consumers side, they will mount a small dish to the roof of their home or business and point it back to the WISP's dish.

A WISP offers public wireless network services. WISPs typically install Wi-Fi wireless hotspots in airports, hotels and other public business places. These hotspots provide Internet access and local area network (LAN) printing for mobile network devices like laptops, handheld computers and cell phones.

To use a WISP, a person must subscribe to their wireless service. Some WISPs offer free Internet service, but many others charge fees and / or require service contracts. When choosing a WISP, a person should ensure the provider’s equipment and software is compatible with his or her own gear. WISPs also vary in the speed and security features they offer.
