Tactical Communication Mobile Application

• Traditional radio systems lacked modern data exchange and mobile interfaces

• Complex integration with professional radio hardware via Bluetooth and USB

• Strict security requirements including encryption and license validation

• Need for uninterrupted 24/7 background operation, including after device reboots

• Reliable real-time communication under unstable or limited network conditions
  
  

Failure or downtime was not acceptable in mission-critical scenarios.
