dPMR is a digital radio protocol specifically targeting highly functional solutions by using low cost and low complexity technology.
dPMR is a narrowband (6,25 kHz) FDMA technology that is 100% digital
that offers many forms of voice and/or data applications. More >>
The dPMR protocol was developed from the outset to specifically avoid technology
that was covered by IPR.
For the simple reason that incurring such licence fees would be against
the whole principle of "low
cost".
dPMR is an open standard published by ETSI and ETSI has the policy of requesting that any known IPR related to any ETSI standard is notified publically via the ETSI website and that the owners of such IPR guarantee to make licences available on Fair Reasonable And Non Descriminatory terms (FRAND).
However, ETSI at no time will undertake any examination of such declared IPRs to check if they are truely valid in relation to the notified standard. It is left to the users of the standard to ascertain for themselves whether they consider the IPR to be valid or not.
'Essential IPR' is a commonly heard phrase these days and it means just that. Any IPR that is really essential will be infringed by any equipment that complies with the standard. In order to avoid such situations, the dPMR standards have been written with more than one possible technique for compliance. So at the same time as inviting possible users of the standard to check whether an IPR is truely valid, users also need to read the standard and see whether the IPR is essential or not required at all.
Members of the dPMR Association have had considerable experience in this area and will be able to advise other members accordingly.
