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.

Since it is difficult for a single service provider to build an infrastructure that offers global access to its subscribers, roaming between service providers is encouraged by the Wi-Fi Alliance with the WISPr protocol. WISPr is a set of recommendations approved by the alliance which facilitate inter-network and inter-operator roaming of Wi-Fi users.
