SDAs (Short Data Applications)


Specially designed to save time, money and effort, our range of apps streamlines essential processes, helping to keep your staff safe and increasing productivity. Data transmission reduces the need for voice calls, conserving valuable bandwidth, and gives fast access to critical information when you need it most.

  • Get an instant response to field enquiries through access to multiple databases 
  • Issue visual alerts: swiftly deliver images to TETRA radios and Java-enabled devices
  • Communicate seamlessly between technologies: email, SMS (GSM/3G/LTE) and SDS (TETRA) 
  • Use building and street maps to track the location of your vehicles and personnel – no extra hardware or user input required 

SDAs can be used to broadcast pre-recorded announcements, update information panels on platforms, streamline train preparation and despatch, and make train shunting much safer.

The SDAs can even be used at stations with no TETRA coverage, by switching the Sepura digital hand-held radios to direct mode (DMO) and using a Sepura SRG gateway radio to extend network coverage.
