The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. The attenuation of signal strength with distance by absorption in the ground is lower than at higher frequencies . There is long wave availability on 198 LW, and a restricted medium wave availability. These correspond to frequencies as low as 3 Hz and as high as 1 gigahertz (109 Hz). Radio 4 was traditionally broadcast on long wave, using frequencies used by the BBC since the 1930s, but the station has long been aired on FM and digital radio and online.

The BBC reckoned that FM reception was good enough and the vast majority of the country ... Radiofrequency (RF) radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. Those higher-frequency signals do not follow the surface of the Earth beyond a few kilometers, but can travel as skywaves, ‘bouncing’ off different layers of the ionosphere at different times of day. Until relatively recently, medium-wave radio was used to broadcast from one European country to another in the Frequency is measured in the unit hertz .

The frequency band used for AM radio is about 550 to 1720 kHz. Low frequency waves can also occasionally travel long distances by reflecting from the ionosphere (the actual mechanism is one of refraction), although this method, called skywave or "skip" propagation, is not as common as at higher frequencies. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'. Many shortwave sets. Determine the frequency of the wave. Canadian Radio Frequency Allocations. This frequency belongs to the radio waves spectrum. Because long-wave signals can travel very long distances, some radio amateurs and shortwave listeners engage in an activity called DXing.
