The IZAR RADIO EXTEND is a transceiver for improving of performance within a radio fixed network as well as mobile reading, especially made for hard-to-read locations. Up to 4 radio devices can be received and transmitted. The simple and effective reading topology stays.


  • Simple and short installation
  • Strengthening of radio signals (OMS-S)
  • For mobile reading and fixed network
  • On-Site-Programming using IrDa interface
  • Battery powered with a lifetime of up to 12 years
  • Principle of operation

    The IZAR RADIO EXTEND is an electronic unit which receives radio telegrams and saves them temporarily. The data which is sent by the IZAR RADIO EXTEND can be stored by using a mobile or fixed receiver.

    Mobile: The IZAR@MOBILE 2 TABLET collects the data in walk-by or drive-by mode in conjunction with the IZAR RECEIVER BT. The data for the reading route is sent directly to the central PC.

    Fixed: An IZAR RECEIVER (IZAR RDC) collects and saves the data to transmit these to a central FTP server cyclically.
