Over 30 years’ experience in PMR and the decision to use TETRA technology since1995 have enabled ETELM to become a major player in the field of digital radio communication infrastructures.
The architectures on offer are flexible and upgradeable, with a comprehensive and modular range of solutions, from micro-networks (single-site, single-carrier) to national networks.
ETELM develops and manufactures the complete Tetra infrastructure technology (base stations, switches, dispatching, applications, repeater, optic link etc.) and supplies Tetra systems indirectly through Authorised Systems Integrator worldwide and directly to Key Account managing projects from start to finish (engineering, deployment, turnkey solutions, etc.).
ETElm's e-TBS technology is the fully integrated professional radio system to be fully integrated with 4G LTE networks. The system offers gateway free convergence of Heterogenous Networks (wideband and narrowband systems) allowing smooth migration of professional radio services over a private or public operator's wideband LTE network. This provides secure voice as a VPN of a public network and also allows seamless calls between different technolgies using standard subscriber equipement. In addition the system uses the same backbone core network and reduces deplyment costs significantly.
