Ericsson will launch satellite phones in 1999. They will operate both on either GSM/AMPs networks, and via satellite, in areas where there is no coverage.
A wireless phone that uses mobile satellite service to send voice and data.
Mobile satellite services refers to networks of communications satellites intended for use with mobile and portable wireless telephones. There are three major types: AMSS, LMSS, and MMSS. A phone connection using MSS is similar to a cellular telephone link, except the repeaters are in orbit around the earth, rather than on the surface. MSS repeaters can be placed on geostationary, medium earth orbit, or low earth orbit satellites. Provided there are enough satellites in the system, and provided they are properly spaced around the globe, an MSS can link any two wireless telephone sets at any time, no matter where in the world they are located. MSS systems are interconnected with land-based cellular networks.
Phones that connect callers via satellite. The idea behind a satellite phone is to give users a worldwide alternative to sometimes unreliable digital and analog connections. So far, such services have proven very costly and have appealed to few users aside from, for example, the crews at deep-sea oil rigs with phones configured to connect to a satellite service.
A satellite telephone, satellite phone, or satphone is a mobile phone that communicates directly with orbiting communications satellites. Depending on the architecture of a particular system, coverage may include the entire Earth, or only specific regions.
