Problem Resolution
 
In most communication systems, it is desirable for data not only to reach the destination, but also for the data to arrive in a reliable and consistent manner. In general, wireless communications tend to be subject to more interference and lost data than a wired system. Because radio frequency transmissions take more errors, usually some sort of protocol and packetization of data is done to help ensure data integrity and make sure the data safely arrives at the destination. This application note discusses various modes of data transmission and built-in features available in some Digi radios that aid with reliable data transmission.

The following scenarios will be discussed:

  • Basic transmission
  • Point-to-point with Retries
  • Digi Method of Retries
  • Digi Point-to-Multipoint solution (remote initiated)
  • Point-to-Multipoint (base or remote initiated)
