Sepura has unveiled the SC21 next-generation, high-performance small smart TETRA hand-held radio at Critical Communications World (CCW) 2017, Hong Kong. Class 3 RF Transmission Featuring a wide range of functionality inherited from the ground-breaking SC20 hand-portable, the SC21 is small and lightweight, yet delivers class-leading performance. With a powerful TETRA engine offering Class 3 RF transmission and exceptional receive sensitivity, it allows users to continue communicating in areas where other small radios lose reception. “Users told us that they had been looking for a compact radio that could be worn on a lapel or in a pocket, but they had found that a smaller size often meant compromising on performance, usability or audio quality – something that’s unacceptable in mission critical scenarios,” said Mark Barnby, Sepura’s Head of Product Management for Devices. Unique Water-Porting Technology “The SC21 is 25% smaller than the SC20, yet its best-in-class audio capability, enhanced by unique water-porting technology, allows for uncompromised audio clarity, even in continuous heavy rain. The well-spaced keys and large, sunlight-visible screen—the largest on any TETRA hand-held—make it a highly functional radio and the small, streamlined case means it’s also easily concealed for discreet or fully covert use.” “Importantly, the powerful TETRA engine inherited from the SC20 extends coverage, giving up to one extra wall of penetration—a factor that can make the difference between life and death in critical situations.” Impressive Functionality And Real-World Usability Juan Ferro, Sepura’s Chief Commercial Officer, added: “Today’s launch is a significant landmark: the SC21 is ideal for users looking for a smaller, lighter hand-held – with no compromise on performance.” “Its powerful combination of impressive functionality and real-world usability is testament to our responsiveness, and our desire to provide our global customer base with the very best products to tackle their daily operational requirements.”

The mission critical LTE network solution was designed to comply with the rigorous availability and security parameters Teltronic, part of the Sepura Group, has - in partnership with Técnicas Competitivas - successfully deployed the first mission critical LTE network in Europe. Already fully operational, the deployment provides complementary broadband services to RESCAN, the private TETRA network of the Canary Islands’ Public Safety agencies, whose end users include ambulance, police and environmental services. Integrating Different Wireless Technologies Building on the existing Teltronic NEBULA system, the solution utilizes an eNEBULA system deployed as a hybrid TETRA-LTE network, the MVC-6000 – a vehicular system capable of integrating different wireless technologies such as TETRA and professional LTE – and rugged commercial LTE handhelds to provide services such as real-time field-to-control video transmission, internet and intranet access, and customized applications that tackle the agencies’ operational challenges. Security Parameters In Critical Mission Environments The solution was designed to comply with the rigorous availability and security parameters required in critical mission environments and, in addition to high data transmission rates, offers low latencies in call establishment and data transmission; integrated network management system for both TETRA and LTE radio access; and specific functionalities for professional communications, such as group calls, emergency calls or priority management. In accordance with spectrum regulations for Public Safety users and broadband services laid out in Spain’s National Table of Frequency Allocations, the system was implemented in frequency bands below 1GHz, bringing additional benefits in terms of radio propagation and indoor coverage. Evolution Of Existing TETRA Systems “A hybrid TETRA-LTE network expands the range of services available to PMR users, protecting their investment while maintaining the same levels of security, reliability and resilience,” said Juan Ferro, Sepura’s Vice President Systems. “This revolutionary deployment represents a significant milestone in mission critical communications and provides a clear path for the evolution of existing TETRA systems.” Save
