Turks and Caicos Islands
general assessment: fair cable and
radiotelephone services
domestic: NA
international: 2 submarine cables; satellite earth station - 1
Intelsat (Atlantic Ocean)
Tuvalu
general assessment: serves particular needs for internal
communications
domestic: radiotelephone communications between islands
international: NA
Uganda
general assessment: seriously inadequate; two cellular
systems have been introduced, but a sharp increase in the number of
main lines is essential; e-mail and Internet services are available
domestic: intercity traffic by wire, microwave radio relay, and
radiotelephone communication stations, fixed and mobile cellular
systems for short-range traffic
international: satellite earth stations - 1 Intelsat (Atlantic
Ocean) and 1 Inmarsat; analog links to Kenya and Tanzania
Ukraine
general assessment: Ukraine's telecommunication development
plan, running through 2005, emphasizes improving domestic trunk
lines, international connections, and the mobile cellular system
domestic: at independence in December 1991, Ukraine inherited a
telephone system that was antiquated, inefficient, and in disrepair;
more than 3.5 million applications for telephones could not be
satisfied; telephone density is now rising slowly and the domestic
trunk system is being improved; the mobile cellular telephone system
is expanding at a high rate
international: two new domestic trunk lines are a part of the
fiber-optic Trans-Asia-Europe (TAE) system and three Ukrainian links
have been installed in the fiber-optic Trans-European Lines (TEL)
project which connects 18 countries; additional international
service is provided by the Italy-Turkey-Ukraine-Russia (ITUR)
fiber-optic submarine cable and by earth stations in the Intelsat,
Inmarsat, and Intersputnik satellite systems
United Arab Emirates
general assessment: modern system of microwave
radio relay and coaxial cable; key centers are Abu Dhabi and Dubai
domestic: microwave radio relay and coaxial cable
international: satellite earth stations - 3 Intelsat (1 Atlantic
Ocean and 2 Indian Ocean) and 1 Arabsat; submarine cables to Qatar,
Bahrain, India, and Pakistan; tropospheric scatter to Bahrain;
microwave radio relay to Saudi Arabia
United Kingdom
general assessment: technologically advanced domestic
and international system
domestic: equal mix of buried cables, microwave radio relay, and
fiber-optic systems
international: 40 coaxial submarine cables; satellite earth stations
- 10 Intelsat (7 Atlantic Ocean and 3 Indian Ocean), 1 Inmarsat
(Atlantic Ocean region), and 1 Eutelsat; at least 8 large
international switching centers
United States
general assessment: a very large, technologically
advanced, multipurpose communications system
domestic: a large system of fiber-optic cable, microwave radio
relay, coaxial cable, and domestic satellites carries every form of
telephone traffic; a rapidly growing cellular system carries mobile
telephone traffic throughout the country
international: 24 ocean cable systems in use; satellite earth
stations - 61 Intelsat (45 Atlantic Ocean and 16 Pacific Ocean), 5
Intersputnik (Atlantic Ocean region), and 4 Inmarsat (Pacific and
Atlantic Ocean regions) (2000)
Uruguay
general assessment: fully digitalized
domestic: most modern facilities concentrated in Montevideo; new
nationwide microwave radio relay network
international: satellite earth stations - 2 Intelsat (Atlantic
Ocean) (2002)
Uzbekistan
general assessment: antiquated and inadequate; in serious
need of modernization
domestic: the domestic telephone system is being expanded and
technologically improved, particularly in Tashkent (Toshkent) and
Samarqand, under contracts with prominent companies in
industrialized countries; moreover, by 1998, six cellular networks
had been placed in operation - four of the GSM type (Global System
for Mobile Communication), one D-AMPS type (Digital Advanced Mobile
Phone System), and one AMPS type (Advanced Mobile Phone System)
international: linked by landline or microwave radio relay with CIS
member states and to other countries by leased connection via the
Moscow international gateway switch; after the completion of the
Uzbek link to the Trans-Asia-Europe (TAE) fiber-optic cable,
Uzbekistan will be independent of Russian facilities for
international communications; Inmarsat also provides an
international connection, albeit an expensive one; satellite earth
stations - NA (1998)
Vanuatu
general assessment: NA
domestic: NA
international: satellite earth station - 1 Intelsat (Pacific Ocean)
