In Antarctica adequate communications can be a matter of life and death. Communication systems are therefore a key part of any research station. All stations (and ships) have permanent satellite links to the outside world providing broadband internet and a sophisticated telephone network.

Radios and portable satellite phones provide communication with field parties, ships and aircraft. Within the stations themselves, there are telephones and walkie-talkie systems.

However, all these systems can be disrupted by the weather or atmospheric phenomena.
