DiCal-RED is a radio module for communication between emergency vehicles and
control rooms. It provides Ethernet, Wi-Fi and cellular network connectivity
and runs a Linux- and BusyBox-based operating system.

"The DiCal-Red radio data module reliably guides you to your destination. This
is ensured by the linking of navigation (also for the transmission of position
data) and various radio modules."

Due to the use of unmaintained third-party software components, the device is
vulnerable to numerous known security issues.
