Fixed Satellite Service (FSS) uses Very Small Aperture Satellite (VSAT) terminals to provide high data rate wide area two way communications nearly anywhere that has a clear sky view. This technology is used to deliver satellite television (e.g., DirecTV, DISH, etc.) although it can also be used to provide other types of data communication. When used in a two way system the terminals generally include a 1 meter (i.e. larger than a TV dish antenna) dish antenna. These systems may be useful in remote areas where RSUs are too far away to be serviced by conventional wide area radio links. Strengths: Very flexible in terms of geographic locations, generally high data rates. Limitations: VSAT antennas are somewhat large for most physical installations (e.g., at a controller cabinet), may be subject to weather related performance issues, may require periodic maintenance (snow/ice removal, etc.).
