The 49MHz frequency region of the radio spectrum falls just below the 6 Meter Ham Radio Band. The 49MHz band is often used for FCC Part 15 devices such as remote control toys, baby monitors, cordless phones, and walkie talkies. The 49MHz bad is also shared with military operations, petroleum operations, and the occasional public safety allocation.
Cordless phone use has moved away from this low frequency VHF band. There is little activity today in the 49MHz region.
Although the 49MHz region falls just below the 6 Meter Ham Radio Band, it should NOT be presumed that 49MHz is in a 5 Meter Band, as it is not. There once was a 5 Meter Ham Radio Band that the FCC took away, and the frequency range was higher, not lower, than the current 6 Meter band. As this demonstrates, nomenclature is not always mathematically correct to actual wavelength.
