Radiofrequency wireless communication (rf) makes communication possible in remote, challenging or harsh conditions. You may not be able to get a cell signal in your basement, but through rf technology, drones are able to send photos and data from the vent hole of an active volcano.
Rf communication works through electromagnetic radio waves. Radio and television have used rf technology for a long time, but applications like WiFi, Bluetooth and GPS all use a similar system that relies on components such as an rf directional coupler, combiners, meters and filters.
Radiofrequency technology can be used to communicate from remote areas where sending data has been a challenge. Transmitting stations and repeaters are set up that allow researchers to work in places that have been inaccessible before. Whether at the top of a mountain, inside a volcano or on a glacier in Antarctica, wireless communication has enabled many new discoveries.
Working in less than optimal conditions makes communication especially difficult. High winds, extreme heat and water are challenges that must be overcome for communication to be successful. RF components are made to withstand extreme conditions and keep the lines of communication open. One challenge for radio frequency applications has been communication under water because radio waves do not move very well through water. Sonar has been used for communications at sea, but researchers are making progress using WiFi technology.
One of the most useful applications of radiofrequency communication technology is in space. From the International Space Station to the Mars rovers, rf technology keeps the crew on Earth in contact with people and devices working in space.
Thanks to electromagnetic waves, people can keep in touch from wherever they may be. From the top of a mountain to a remote desert or in orbit around the Earth. Radiofrequency technology keeps us connected.
