Due to the bandwidth limitations of their traditional voice-centric LMR (Land Mobile Radio) networks, public safety agencies are keen to leverage commercial cellular network technology to support their growing broadband application needs. Considering its thriving ecosystem, spectrum flexibility and performance metrics, LTE has emerged as the leading candidate for public safety mobile broadband networks.
Standardization efforts are still underway to enhance the LTE standard for public safety requirements, including MCPTT (Mission Critical PTT) functionality, group communications and proximity services. However, this has not deterred public safety agencies from early deployments of the technology, particularly in the Middle East and Asia Pacific regions. The Qatar MOI made headlines when it deployed a private 800 MHz LTE network to complement its existing TETRA network with broadband applications. Since then, several private LTE networks have sprung up across the globe. For example, the Lijiang Police in China is utilizing a 20 site private LTE network for video surveillance and related applications. While most initial public safety LTE investments were limited to small scale networks, South Korea
