Radio Technology Explained



Internet radio

WIFIInternet radios use the same wireless technology as portable computers to access radio stations from across the world and enjoy a great selection of podcasts – all on a device which looks, feels and sounds like a radio. And internet radios are much more energy efficient than listening on a computer, or through your TV.

With an internet radio you can enjoy the following great content away from your PC.

The vast majority of internet radios also include FM, meaning that you get the best of both worlds.

Some internet radios, like Sensia, also offer features like a color touchscreen, and apps such as Twitter, Facebook and Picasa. Pure internet radios also update themselves automatically, downloading and adding new product features as soon as they become available.

FM radio

RDSPioneered in the United States in the 1930s, FM radio has been used for many decades alongside the more widely used but poorer quality AM. Bolstered by an upsurge in high fidelity equipment in the late 1950s, and by its adoption by AOR fans in the 1960s and 1970s, FM finally became the major listening band in the 1990s following its adoption by top 40 and country music stations. FM is broadcast at frequencies of 87.8-108 MHz in the USA.

All of our radios include FM reception for go-anywhere access to local and national stations and come with RBDS. The Radio Broadcast Data System provides extra text information, like station name, artist name and track title for most music stations, and station and program name for most talk stations.
