Antarctica has many research stations and field stations used for scientific research. Each country has their own communications resources to maintain contact between their research stations, field stations, and home countries.
Stations and camps at higher latitudes cannot access communication satellites and will use HF radio communications to supplement polar orbiting satellites. VHF and UHF radios are used for communications closer to the stations.
