Telecommunications in Guinea include radio, television, fixed and mobile radio, and the Internet. The people of Guinea are among the poorest in West Africa and this reality is reflected in the development of the country's telecommunications environment. Radio is the most important source of information. .
Radio remains the most important source of information for the public, and the only one to reach the entire country. The government licensed the country's first private broadcasters in 2006.• .

Diversity techniques To improve the quality of the received signal, often two receiving antennas are used, placed at a distance equal to an odd multiple of a quarter of the corresponding wavelength. For 900 MHz, this wavelength is 33 cm. This technique, known as antenna diversity or space diversity, avoids interruption caused by path fading. The antennas can be spaced horizontally or vertically. Horizontal spacing requires more complex installation, but brings bette. [pdf]
While all mobile and cell phone towers give out different levels of radiation, a minimum safe distance to avoid the worst of it is under 150ft, and after around 500ft, radiation levels will be minimal. However, the best way to test for yourself is with an EMF radiation meter. [pdf]

From 1 January 2023 Latvia banned the import of natural gas from Russia. The replacement comes from connections to LNG terminals, the LNG terminal in Lithuania, and from 2024 the recently opened Inkoo LNG terminal in Finland. JSC Conexus Baltic Grid is the natural gas in Latvia. International transmission pipelines are 577 km long, consisting of the Riga–Pahneva, Pleskava–Riga, Izbors. [pdf]
