Neighborhood Internet service provider
A neighborhood Internet service provider (NISP) is a small scale broadband internet service provider targeted at a single subdivision or neighborhood. They are built in a neighborhood to provide Internet access to residents in the community, often using rooftop antennas in a hub-and-spoke arrangement to bridge the last few hundred feet to the residences (or possibly businesses).
