  • DMR / Digital Message Receiver

    The Digital Message Receiver is a mobile POCSAG receiver for alerting emergency services, e.g. the volunteer fire brigade or the rescue service. It is a terminal device which is usually worn on the body and which receives alarm texts via radio from the digital alarm converter.

  • Digital Alarm Converter

    An important component of digital alerting is the digital alarm converter. The digital alarm converter is a radio base station for the operation of POCSAG alarm networks. It receives the alarm text either directly from the digital alarm transmitter in the control centre or via radio from other digital alarm converters in the radio network. The digital alarm converter forwards the alarm text to POCSAG terminals (e.g. Digital Alarm Receiver) and/or to other digital alarm converters.

  • DA / Digital Alerting

    Digital alerting generally refers to a procedure for notifying and alerting the emergency forces of authorities and organisations with security tasks. In contrast to analogue alerting, the alarm texts are available in digital form so that digital signal processing methods can be used (e.g. text instead of tone-only or tone and voice alerting). Usually, the alarm texts are distributed via a radio network, consisting of a digital alarm transmitter in the control centre, various base stations distributed in the radio network (digital alarm converter), as well as the end devices of the emergency forces.

  • Circuit-Switched

    Circuit switching is a methodology of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the channel and remains connected for the duration of the communication session.

  • 3GPP

    The 3rd Generation Partnership Project (3GPP) is a collaboration between groups of telecommunications associations, known as the Organisational Partners. The initial scope of 3GPP was to make a globally applicable, third-generation (3G) mobile phone system specification. This was to be based on evolved Global System for Mobile Communications (GSM) specifications within the scope of the International Mobile Telecommunications-2000 project of the International Telecommunication Union (ITU). The scope was later enlarged to include the development and maintenance of:
    - GSM and related “2G” and “2.5G” standards including GPRS and EDGE;
    - UMTS and related “3G” standards including HSPA;
    - LTE and related “4G” standards; and
    - An evolved IP Multimedia Subsystem (IMS) developed in an access independent manner.

  • 3G

    3G is the third-generation of mobile telecommunications technology. This is based on a set of standards used for mobile devices, mobile telecommunications and specifications. 3G finds application in wireless voice telephony, mobile internet access, fixed wireless internet access, video calls and mobile television.

  • 2G

    2G is short for second-generation wireless telephone technology. Second generation 2G cellular telecoms networks were commercially launched on the GSM standard.
