What Is Fixed Wireless Internet?

Licensed fixed wireless Internet links can reach distances of 30 miles or more.

Fixed wireless Internet technology has been used for many years in ISP core networks. Evolving technology makes this flexible broadband service a viable option to cable and DSL.

Function

Fixed wireless Internet connects a stationary location such as a home or business to another fixed location where the Internet is accessed. The second location could be a telecommunications tower or an ISP network hub, or another home or business. Equipment consisting of an antenna and radio is required at each location; in some cases the antenna and radio are integrated into a single unit. The equipment at the home or business is usually mounted on the exterior of the building, but in some cases may be installed indoors near a window. Speeds up to 155 Mbps can be delivered.

Types

Fixed wireless connections can use licensed or unlicensed radio frequencies. Licensed services have no interference issues and higher power transmission to deliver service at greater distances. Licensed fixed wireless systems can be deployed in "point-to-multipoint" configurations where one aggregation location communicates with multiple user locations. Unlicensed wireless equipment is less expensive but prone to interference and deployed in "point-to-point" configurations.

Benefits

Fixed wireless networks deliver high-speed Internet connections. The networks can be deployed more quickly than wired networks. For sparsely populated rural areas, fixed wireless is often the most cost-effective solution.

Considerations

Fixed wireless equipment often requires line of sight between locations. Foliage, weather and interference can impact performance.
