NEBULA infrastructure for TETRA mobile radio networks delivers excellent coverage, security and reliability in a platform designed for efficient implementation and cost-effective scalability. NEBULA is the only TETRA system that is fully 100% Ethernet /IP based. A secure and reliable network can be built with distributed switching, distributed intelligence, and complete fault-tolerant redundancy, offering lower network costs due to the use of commercially available off-the-shelf equipment.

The Switching Control Node (SCN) is responsible for providing intelligence to the network, integrating user settings, and providing access to standard PMR services.

Our wide range of base stations, fixed and portable, are built to operate in diverse and challenging conditions delivering the best performance in every operational scenario, indoor or outdoor. 

Sepura's Network Management System (NMS) manages and operates the network infrastructure, across TETRA and/or LTE radio technologies.
