CompassCom provides a interface to Motorola Unified Services (UNS) to the Astro p25 radio network. We are currently working on interface to MotoTurbo via the MNIS API. Out interface provides all of the heavy lifting inquired about in this blog as well as Emergency button functionality.
Via our interface to these and other devices we can write to the GeoEvent Extension.
CompassCom in the only Motorola business partner to put Astro radio locations on a map.
Feel free to contact me for more information.
In summary, technologically it is quite possible but care must be taken to involve those who understand the radio network and its capacity and the added volume of your location requests to ensure the total capacity of the RF-transmitted digital bandwidth is not exceeded.
