They operate in 446MHz frequency range, and were developed in accordance with the open DMR standard.

The open DMR standard
Digital Mobile Radio (DMR) is an open standard for professional mobile radio (PMR), developed by the European Telecommunications Standards Institute (ETSI).
DMR systems use a channel range of 12.5 kHz and are compatible with the frequency spectrum of analogue mobile radio. As a result, mobile radio solutions based on the DMR standard enable a simple and cost-ecient migration from analogue to digital technology.
The DMR standard currently dierentiates between three graduations in terms of functionality and performance. Licence-free DMR radios from Hytera correspond at DMR Tier I. Products in accordance with DMR Tier I are used for simple radio communications in the 446-MHz band, with a maximum transmitting power of 0.5 watts (licence-free). For users who require a higher scope of functionality, Hytera also oer both conventional and trunked digital mobile radio systems within our product portfolio.
PMR446 – Licence-free radio for everyone
PMR446 radios can be operated by any user, with no need for proof of identication or a radio licence. The UHF frequency range from 446.0 to 446.2 MHz is assigned to these licence-free radios, whereas the range from 446.0 to 446.2 MHz is reserved for analogue and digital applications respectively. 'PMR' refers to Private Mobile Radio. PMR446 radios feature a permanent antenna with maximum transmitting power of 0.5 Watts.
Our digital PMR446 radios combine the properties of citizens' band radio with the new digital mobile radio standard. With this unique combination, you receive licence-free radios that also oer the extensive functionality of professional digital mobile radio, straight out of the box.
