DMR Essentials Licensing Program

Digital Mobile Radio in Europe


Digital Mobile Radio (DMR) is an emerging European telecommunications standard developed by the European Telecommunications Standards Institute (ETSI) and its members. DMR is intended as a replacement for analog Professional Mobile Radio (PMR) products. Standards documents (TS 102 361 series) are available via the ETSI website.

DMR operates within three tiers:

Tier I

  • Unlicensed operation in the 446 MHz band.
  • Less than 0.5 W transmit power.


Tier II

  • Licensed operation [subject to national frequency planning].
  • Includes DMR repeater operation.


Tier III

  • Licensed operation [subject to national frequency planning].
  • Includes DMR trunking operation.

Motorola Solutions’ DMR Standards-Based Licensing program grants rights to Motorola Solutions’ DMR essential patent families. Since our patent portfolio is large and expanding, additional patents determined to be essential to the DMR standard are occasionally identified. Once identified, Motorola Solutions declares the patent to ETSI and DMR licensees automatically gain access to these patents without additional cost or administrative burden.

The term of a Motorola Solutions DMR Standards-Based License is for the life of the last-to-expire essential patents, or until the licensee decides to cease DMR equipment manufacturing, whichever comes first. Generally, the license may not be transferred to another party, but Motorola Solutions will consider requests to do so on a case-by-case basis. Grants may include the right to make, distribute and sell DMR-compliant TERMINALS and INFRASTRUCTURE EQUIPMENT. The DMR Standards-Based License is subject to reciprocity. That is, licensees are required to cross-license any patents they may own or control that may be essential to the DMR standard or that are found to be essential in the future.

Financial terms are dependent upon the prospective licensee’s DMR essentials patent holdings, if any, and are linked to an industry normalized equipment index. Royalty rates are expressed in a fixed amount and are reviewed periodically to ensure they remain in line with market trends, technology maturity and portfolio coverage.

Equipment manufacturers entering the DMR marketplace are encouraged to review ETSI’s IPR Policy and contact Motorola Solutions’ Licensing Department to obtain the necessary essential patent rights prior to fielding equipment.

Customers or agencies seeking to purchase or use DMR equipment should discuss essential patent license rights with their prospective vendor/manufacturer. Unwelcome delays, program risks and costs can be encountered if DMR equipment is purchased from an unlicensed manufacturer. We suggest you visit this site periodically to determine if your preferred supplier is licensed.
