Reference excerpt

Telecommunications in Zambia includes radio, television, fixed and mobile telephones, and the Internet.

Radio and television The state-owned Zambia National Broadcasting Corporation (ZNBC) operates three radio networks. Roughly two dozen private radio stations are operating. Relays of at least two international broadcasters are accessible in Lusaka and Kitwe. ZNBC operates one television station, and is the principal local-content provider. There is also several private TV stations. Multi-channel subscription TV services are available.

Telephones

Calling code: +260 International call prefix: 00 Main lines: 82,500 lines in use, 150th in the world (2012); 85,700 lines in use (2011). Mobile cellular: 10.5 million lines, 76th in the world (2012); 8.2 million lines (2011). Satellite earth stations: 2 Intelsat (1 Indian Ocean and 1 Atlantic Ocean), 3 owned by Zamtel (2010). Facilities are among the best in sub-Saharan Africa. High-capacity microwave radio relay connects most larger towns and cities. Several cellular telephone services are in operation and network coverage is improving. A domestic satellite system is being installed to improve telephone service in rural areas. Very small aperture terminal (VSAT) networks are operated by private firms.

Internet Top-level domain: .zm Internet service is widely available. Internet users: 1.9 million users, 93rd in the world; 13.5% of the population, 160th in the world (2012); 816,200 users, 105th in the world (2009). Fixed broadband: 14,785 subscriptions, 138th in the world; 0.1% of the population, 166th in the world (2012). Wireless broadband: 90,643 subscriptions, 121st in the world; 0.7% of the population, 137th in the world (2012). Internet hosts: 16,571 hosts, 122nd in the world (2012). IPv4: 162,816 addresses allocated, less than 0.05% of the world total, 6.8 addresses per 1000 people (2012).

Internet censorship and surveillance Internet access is not restricted and individuals and groups freely express their views via the Internet, however the government frequently threatens to deregister critical online publications and blogs. In October 2012 the government attempted to deregister the blog Zambian Watchdog, but was unsuccessful because the blog was hosted abroad and therefore outside government control. The constitution and law provide for freedom of speech and press, however the government uses provisions contained in the law to restrict these freedoms. The government is sensitive to opposition and other criticism and has been quick to prosecute critics using the legal pretext that they had incited public disorder. Libel laws are used to suppress free speech and the press. The constitution and law prohibit arbitrary interference with privacy, family, home, or correspondence, but the government frequently does not respect these prohibitions. The law requires a search or arrest warrant before police may enter a home, except during a state of emergency or when police suspect a person has committed an offense such as treason, sedition, defamation of the president, or unlawful assembly. Police routinely enter homes without a warrant. The law grants the Drug Enforcement Commission (DEC), the Zambia Security Intelligence Service (ZSIS), and police authority to monitor communications using wiretaps with a warrant issued on the basis of probable cause, and authorities generally respect this requirement.

Worked examples

Example 1 — a first encounter with Telecommunications in Zambia

Start with the simplest possible case. Write down what Telecommunications in Zambia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telecommunications in Zambia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telecommunications in Zambia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telecommunications in Zambia

In research: Telecommunications in Zambia appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telecommunications in Zambia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telecommunications in Zambia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet in Zambia, Telecommunications in Zambia, so understanding it makes those chapters shorter.
In everyday life: Look for Telecommunications in Zambia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
