A Wireless Internet Service Provider or WISP is a special kind of broadband service provider that uses a base station antenna to transmit data through the airwaves to a receiving antenna at a customer's premises. The data transmission works in a similar manner to a satellite dish. The main difference is that a wireless Internet data antenna sends and receives information from a local tower or tall structure versus a satellite.
WISPs use designated channels of spectrum to transmit large amounts of data, both upstream and downstream, over the airwaves. The fact that the service is transported over a wireless connection is transparent to customers who receive up to 10 Mbps of bandwidth via a regular Ethernet connection.
