A Wireless Internet Service Provider (WISP) is a type of internet service provider that specializes in delivering internet access through wireless means. Typically, WISPs are known for setting up internet access points in public areas known as hotspots or hotzones, where Wi-Fi technology is predominantly used to provide wireless connectivity.

Beyond public spaces, WISPs also cater to the internet needs of residential users and small to medium-sized businesses. For these purposes, WISPs often employ Fixed Wireless Access (FWA) technologies, such as WiMAX, to establish a more stable and dedicated wireless internet connection. This approach enables WISPs to offer a reliable internet service that can serve as an alternative to traditional wired broadband, especially in areas where laying cables is challenging or cost-prohibitive. Thus, WISPs play a significant role in expanding internet accessibility, leveraging various wireless technologies to meet diverse connectivity needs.
