Wireless Internet Service Provider ( WISP , German about: "wireless Internet service provider") or frequently correctly Wireless Internet Access Providers ( WIAP ) is a provider of wireless Internet access via radio , often realized with WLAN ( Wireless Local Area Network ) or WLAN Network in the WMAN ( Wireless Metropolitan Area Network ). The largest WISP and WIAP, measured by the number of participating access nodes ("wireless access points"), are in the USA and Canadawhere entire cities were wirelessly connected to the Internet.

Just like a conventional ISP, wireless Internet service and access providers provide their customers with access to the Internet (often for a fee) . The use of the access is usually subject to certain conditions that are contractually stipulated in the terms of use. WISPs are subject to certain requirements of the Telecommunications Act (TKG) if more than 1,000 customers are connected to the network .

In Germany and Austria, this technology is mainly used in areas where there is no possibility of a broadband connection due to length restrictions. The so-called MIMO technology ( 802.11n ) is very often used here . Directional radio links of 15 km and more with bandwidths of up to 400 Mbit are not uncommon. Centralized systems are usually set up, which are secured by firewalls at the transition points to the actual Internet service provider . Decentralized systems that are interconnected by the OLSR or BATMAN protocol are also very common .
