Fixed wireless data (FWD) links are often a cost-effective alternative to leasing fiber or installing cables between the buildings.
The point-to-point signal transmissions occur through the air over a terrestrial microwave platform rather than through copper or optical fiber; therefore, fixed wireless does not require satellite feeds or local telephone service.
Fixed wireless services typically use a directional radio antenna on each end of the signal (e.g., on each building).
They are usually selected to make the beam as narrow as possible and thus focus transmit power to their destination, increasing reliability and reducing the chance of eavesdropping or data injection.
In rural areas where wired infrastructure is not yet available, fixed-wireless broadband can be a viable option for Internet access.
