Epidemics, wildfires, earthquakes, storms, locust plagues, floods, air crashes... The year 2020, which has just passed, was like a magical blockbuster, and the successive disasters caught us off guard... Emergency relief and disaster relief, communication comes first. How to establish effective communication guarantees in the first place after a disaster occurs has become an important issue for emergency management departments to consider.

In the process of handling emergencies, due to the different roles played by various personnel, the required communication support methods are also different. Commanders need to understand the on-site situation in real time through images and videos, so as to control the overall development of the on-site situation. First-line personnel need simpler voice communication support. In order to meet the different emergency on-site communication support needs, multiple communication systems with different systems are often deployed to achieve this. Multiple systems are independent of each other and are difficult to interconnect, which is not conducive to rapid and convenient deployment on site.

As an important equipment and solution provider in the domestic emergency communication field, Far East Communications, based on the pain points of emergency users' on-site application needs, combined with years of independent research and development experience in LTE, PDT, and TETRA technologies, has launched an emergency on-site broadband and narrowband integrated wireless communication solution. Relying only on a highly integrated, integrated, and lightweight "broadband and narrowband integrated portable station", it can provide "LTE video coverage of key areas" and "PDT voice coverage of long-distance and vast areas" combined high-efficiency emergency on-site communication guarantee capabilities, realizing unified command and overall control of on-site communication, and at the same time meeting the requirements of emergency on-site for lightweight, integrated, and easy-to-use emergency equipment. Currently, this solution has been successfully applied to many emergency users in Jilin Province, Hebei Province and other places.

Emergency on-site broadband and narrowband integration solution

When a disaster occurs, the public network communication on site is paralyzed. Through the rapid deployment of the broadband and narrowband integrated portable station, an emergency communication network is established on site. First-line personnel carry various terminals such as LTE terminals, PDT terminals, and multi-mode terminals to carry out rescue and disposal work on site. Various terminals are uniformly grouped, and can seamlessly exchange information with each other; establish an information transmission channel between the forward command post and the site, and realize remote unified command and dispatch of first-line personnel; at the same time, the forward command post can report to the rear command center through various transmission links. Thus, a three-in-one three-dimensional command system of "rear command center-forward command post-disaster site" is established.

Broadband and narrowband integrated portable station

As the core equipment of the emergency on-site broadband and narrowband integrated solution, the broadband and narrowband integrated portable station independently developed by Far East Communications adopts an integrated design, with a total weight of less than 20 kg. It can be set up by a single person or vehicle, and supports LTE/PDT/MESH and other wireless communication systems. From the system level, LTE, PDT, and self-organizing networks are deeply integrated to realize on-site broadband and narrowband private network coverage and self-organizing network backhaul functions, with low intercommunication delay and high service quality.
