Send five times more GPS with MOTOTRBO Single CSBK

CSBK data was introduced in R2.3. This feature allows a radio to send a single unconfirmed CSBK (Control Signalling BlocK) burst containing ARS, GPS or XCMP data. This results in improved data communication performance and communication reliability. In the past, (i.e. without CSBK Data) it was only possible to send a maximum of around 180 GPS updates per minute per radio per slot. Based on the same parameters, and using CSBK data, it is possible to achieve around 909 GPS updates per minute per radio per slot - a five fold increase!

  1. Good morning, Mr. Holmes,

    When GPS is enabled on radios, can talk-group calls prevent GPS transmissions ?

    Another question, is it possible to track the movements of radios in real time (seconds by seconds for exemple) ?

    Thank you

    1. By default, when a voice call is in progress, no GPS updates will be sent. There is a mechanism for a 3rd party application to interrupt a voice call to pass data (like transmit interrupt) but this is not a radio feature as such.

      You can have a 1s Update rate if there are only a few radios, no other data, and nobody speaks on the radio.

  2. Thank you for that clarification.

    So if a call stops the GPS, when the call is finished, how long does it take for the GPS to activate again ?

    Also, a question I ask myself, how much GPS data can a relay deal with simultaneously if multiple vehicles send their GPS positions at the same time ?

    1. GPS updates will resume as soon as the call ends.
      If Enhanced GPS is used, updates are coordinated with minimal risk of collisions.
      The MOTOTRBO System Planner has some information on estimating data loading.

  4. Hello Mr Holmes,
    I'm Korean engineer.
    Is ARS must-do?

    1. ARS is optional but it makes sense to use it when using GPS.

  5. Hi, Mr Wayne.
    I'll ask you one more thing.
    Can I use CSBK data without a repeater?
