The introduction of IP standards has revolutionized LMR, shifting it from proprietary single vendor networks to open interface, multi-vendor environments.

With the rapid pace of development of wireless networks and the massive proliferation of smart mobile devices, broader opportunities for PTT over cellular (PoC) solutions are emerging.

7 proven reasons why smooth evolution is the better way

Ways to reduce the risk of costly outages, and allow more efficient use of increasingly-constrained resources.

With the development of technologies, the broadband becomes the overall trend of wireless communication system. The private network system has also been developing in the direction of IP, diversified business, broadband data and multi-mode terminal. LTE meets the needs of customers for image, video and high speed data transmission, however it used to fall short in trunking voice features, which mission and business critical users heavily rely on for their routine job and emergency response. In order to solve these problems, 3GPP proposed the Mission Critical Service (MCS) broadband trunking technology.
