Course Overview
With the Advent of 4G Long Term Evolution (LTE) in last few years, broadband services like video streaming have added value to mobile communication networks. Even though, some organizations like law enforcement agencies, airports, fire departments, Public Metros etc. that need guaranteed communication public safety networks, have not been able to benefit from these potentially life-saving innovations. Many of these organizations still rely on the highly secure and mission-critical professional mobile radio (PMR) standard TETRA Rel. 1, which is optimised for effective voice communications but is not equipped to handle high-bandwidth services.
With the help of TETRA over LTE, we can extend the capacities and capabilities of a TETRA network to provide enough bandwidth comparable to modern LTE broadband networks and without requiring enormous investments. Therefore, it offers a smart solution for adopting commercial or dedicated mobile broadband networks within a TETRA environment, while still guaranteeing higher levels of security and reliability. This training course will help you with a complete understanding of the technology TETRA over LTE and its performance management, Integration and complete know-how of currently running deployments and specifications from 3GPP and other standard organizations. You are empowered with the necessary strategies and ways to improve your already existing LTE/TETRA network to seamlessly integrate with TETRA over LTE functionalities with the help of industry-specific standards and use cases.
Why This Course Is Required?
TETRA over LTE has become essential for public safety organizations that rely on mission-critical TETRA networks for voice communications but need to integrate high-bandwidth broadband services without compromising security and reliability standards. The complexity of hybrid TETRA-LTE systems requires specialized knowledge in network architecture, security protocols, and integration procedures to enable seamless transition from legacy TETRA systems to modern broadband capabilities while maintaining the mission-critical characteristics required for emergency communications.
The essential need for comprehensive training in TETRA over LTE technology is underscored by the challenge faced by law enforcement agencies, airports, fire departments, and other public safety organizations that need guaranteed communication but cannot benefit from broadband innovations due to their reliance on TETRA systems optimized for voice but not high-bandwidth services. Engineers and technicians must master the principles of hybrid network deployment, understand security considerations for interconnection, and apply proper integration strategies to extend TETRA network capabilities while preserving mission-critical reliability.
Research demonstrates that many public safety organizations still rely on the highly secure and mission-critical professional mobile radio (PMR) standard TETRA Release 1, which is optimized for effective voice communications but is not equipped to handle high-bandwidth services, while TETRA over LTE offers a smart solution for adopting commercial or dedicated mobile broadband networks within a TETRA environment while still guaranteeing higher levels of security and reliability.
