Telecommunications in Antarctica take place between research stations and either other stations or external contacts. Communication infrastructure is provided by the country which administers each base.
Telephone communication
United States bases
- Telephones – main lines in use: 0 (note: information for US bases only, 2001)
- Telephones – mobile cellular: Argentine bases have GSM networks provided by Argentinean carriers Claro and Movistar; Iridium system in use
- Telephone system
- general assessment: local systems at some research stations
- domestic: N/A
- international: via satellite from some research stations
Australian and New Zealand stations
Five locations (Casey Station (AU), Davis Station (AU), Macquarie Island Station (AU), Mawson Station (AU) and Scott Base (NZ)) all have telephone connections that enable direct dialling to and from the outside world. Connections to the Australian stations is via the country calling code +672.
Argentinian and Chilean bases within their claims, which have families living at them, are also connected by direct dial connections.
Connection to Scott Base and the nearby United States base McMurdo Station is via the New Zealand country calling code +64 (see Telecommunications in New Zealand).
Television

Internet
Internet Service Providers (ISPs): Argentine bases have WiFi provided by Argentinean internet provider Speedy (now called Movistar), a fiber cable[clarification needed] on polar plateau which was installed in 2009.[citation needed]

Data access to the Amundsen–Scott South Pole Station is provided by access via NASA's TDRS-F1, GOES & Iridium satellite constellation. Marisat F-2 provided data communications until it was retired in 2008. For the 2007-2008 season, the TDRS relay (named South Pole TDRSS Relay or SPTR) was upgraded to support a data return rate of 50 Mbit/s, which comprises over 90% of the South Pole's data capability, which is used primarily for scientific data return.[1][2]
The Australian Stations each have a satellite data connection, currently contracted to Speedcast. This provides each station with a 9Mbps symmetric connection.
Data & Telephony access to Scott Base - New Zealand is provided via C-Band by Spark NZ & Horizons 3E.
Regarding Argentine bases in general, Marambio Base has wireless internet and 2 mobile phone servers.
Orbcomm satellites which pass over Antarctica can relay short messages to and from transceiver units to email or XML over HTTP.
Radio
Official broadcasts
- Argentina Bases: Radio Nacional Arcangel San Gabriel, Esperanza Base, on 15476 kHz with 2 kW and 97.6 MHz. QSL cards verified.
- Chile Bases: Radio Soberania, Villa las Estrellas on 90.5 MHz with 100 W.
- United States Bases: American Forces Antarctic Network AFAN McMurdo, on 93.9 MHz with 30 W and 104.5 MHz with 50 W.[3]
- Scott Base - New Zealand: Scott97FM, On 97.0 MHz with 25 W
Amateur radio
Several bases used their transceivers also to provide amateur radio worldwide communications on HF or amateur radio satellites with specific club callsigns, also useful on utility and emergency communications.
