pospheric scatter - a form of microwave radio transmission in which
the troposphere is used to scatter and reflect a fraction of the
incident radio waves back to earth; powerful, highly directional
antennas are used to transmit and receive the microwave signals;
reliable over-the-horizon communications are realized for distances up
to 600 miles in a single hop; additional hops can extend the range of
this system for very long distances.
trunk network - a network of switching centers, connected by
multichannel trunk lines.
UHF - ultra high frequency; any radio frequency in the 300- to 3,000-
MHz range.
VHF - very high frequency; any radio frequency in the 30- to 300-MHz
range.

Terminology
Due to the highly structured nature of the Factbook database, some
collective generic terms have to be used. For example, the word Country
in the Country name entry refers to a wide variety of dependencies,

in addition to the traditional countries or independent states.
Military is also used as an umbrella term for various civil defense,
security, and defense activities in many entries. The Independence
entry includes the usual colonial independence dates and former ruling
states as well as other significant nationhood dates such as the
traditional founding date or the date of unification, federation,
confederation, establishment, or state succession that are not strictly
independence dates. Dependent areas have the nature of their dependency
status noted in this same entry.

Terrain

Total fertility rate
This entry gives a figure for the average number of children that would
be born per woman if all women lived to the end of their childbearing
years and bore children according to a given fertility rate at each
age. The total fertility rate (TFR) is a more direct measure of the
level of fertility than the crude birth rate, since it refers to births
per woman. This indicator shows the potential for population change in
the country. A rate of two children per woman is considered th
