29. Advanced Mobile Phone System (AMPS)

31. D-AMPS (Digital-Advanced Mobile Phone Service), is a digital version of AMPS (Advanced
Mobile Phone Service), the original analog standard for cellular telephone phone service
in the United States.
Both D-AMPSand AMPS are now used in many countries.

41. Medium Earth orbit (MEO), sometimes called intermediate circular orbit (ICO), is the
region of space around the Earth above low Earth orbit (altitude of 2,000 km (1,243 mi))
and below geostationary orbit (altitude of 35,786 km (22,236 mi)).
The most common use for satellites in this region is for navigation, communication,
and geodetic/space environment science. The most common altitude is approximately
20,200 kilometres (12,552 mi)), which yields an orbital period of 12 hours, as used, for
example, by the Global Positioning System (GPS).
