Wireless Communications
Minerva Intercom System | Apollo 3-8 Multi-User System
 
dBD Communications are able to supply a variety of wireless communication systems which are featured on our website here.
 
 
One of these systems is the Minerva Wireless Intercom system. Our Minerva Communication System consists of one headset and a remote intercom for communication between two users. Originally developed for aircraft marshalling, we have broadened our capability and developed further variations for the system such as:
 

 

– Can be integrated with other communication devices  such as handheld radios.

 

– Designs specifically developed  for the Matisa and    Plasser machines on the railways.

 

– Throat Mic variations.

 

– Systems can be supplied in protective red foam if needed.

 

This system allows communication up to 100 metres untethered away from the platform.

 

 

 

Recently we have further developed our Apollo Communication System. Formerly 3-4 users, we can supply communications for up to 8 users in total.
 
Within the airfield environment the baggage handlers have been trialing our Apollo Systems and been using them to communicate with one another whilst in the high noise environment of the aircraft.
 
More information regarding our communication systems can be found here.
