Certifying terminal equipment
Various brands of terminal equipment may be used for public safety digital radio (BOS digital radio). To ensure interoperability, the Act on the Federal Agency for Public Safety Digital Radio (BDBOS-Gesetz) specifies that only terminal equipment certified by this agency may be used for public safety digital radio.
It is indispensable for the operation of public safety digital radio to function properly that all terminal equipment used is interoperable with all other components.
Furthermore, terminal equipment must fulfil certain requirements defined by the Federal Agency for Public Safety Digital Radio in coordination with all stakeholders involved. For this reason, only devices which have been tested and certified by the Federal Agency for Public Safety Digital Radio in a specific procedure may be used.
The certification procedure starts with an application submitted by a manufacturer or supplier of terminal equipment to the Federal Agency for Public Safety Digital Radio and ends with the issuance (or refusal) of a certificate by this agency. The certificate confirms that a specific type of equipment supports the specific requirements of public safety digital radio both in network and direct operation and does not cause any interference. The certification always refers to a specific hardware and software version of a device.
The Federal Agency for Public Safety Digital Radio does not conduct the technical tests itself, but relies on the judgement of competent, certified testing bodies, which conduct interoperability tests of such equipment directly on the request of manufacturers or suppliers.
