Conclusion
In summary, improvements in LTE data rates and reduction in latency can address the important aspects of information domain; quality and speed of information sharing. Leading defense products companies have already added LTE products like ruggedized user equipment or terminals, ruggedized network components like LTE eNodeB, micro cell, pico cell and LTE core. Although 3GPP defined the mission critical features and capabilities with public safety applications in mind, this doesn’t forbid the use of LTE for defense applications. Mission critical aspects of LTE has further increased its applicability to the defense sector as it demands high reachability, availability and reliability of the service, low latency, real-time operating capabilities, highly secured operations, inter-operability with other services and systems, private and group communications, handling of emergencies and ability to provide prioritization, pre-emption, queuing and assured quality of service.
