A wireless Internet service provider (WISP) is an Internet service provider (ISP) that allows subscribers to connect to a server at designated hot spots (access points) using a wireless connection such as Wi-Fi. This type of ISP offers broadband service and allows subscriber computers, called stations, to access the Internet and the Web from anywhere within the zone of coverage provided by the server antenna. This is usually a region with a radius of several kilometers.
VSAT internet and WAN connections have made it possible for companies to move beyond their physical restrictions. WANs, once limited to office blocks in business districts, can now reach previously hard-to-connect remote locations like oil rigs, construction sites, gold mines, and even ad-hoc military camps.
