LPD433 (low power device 433 MHz) is a part of ITU region 1 ISM band which allows for licence free communication devices, using frequencies in the UHF band from 433.075 MHz to 434.775 MHz, within a band traditionally reserved for amateur radio operations at higher RF power levels in most nations woldwide.
LPD hand-held radios are authorized for license-free voice communications use in most of Europe using analog frequency modulation (FM) as part of short range device regulations,with 25 kHz channel spacing, for a total of 69 channels. In some countries, LPD devices may only be used with the integral and non-removable antenna with a maximum legal power output of 10 mW.
Voice communication in LPD band was introduced to reduce the burden on the eight PMR446 channels over shorter ranges (less than 1 km) . In some EU countries voice is not allowed over LPD.
LPD is also used by wireless instruments and digital devices such as car keylocks.
