Changsha Huanghua International Airport in South Central China´s Hunan Province has seen smoother communication between different departments and more accurate dispatching after deploying Hytera´s 400 MHz digital trunking system and multi-mode advanced radios, the company said.
As of September 2018, the flight on-time rate of the airport has remained above 80% for 14 consecutive months, ranking first in the South Central region for 11 consecutive months.
Due to the increase of trade, tourism, exhibition, and cultural exchanges, the traffic volume of Changsha Huanghua International Airport has maintained a strong growth momentum in recent years. As the passenger throughput grows at a rate of 8% every year, security facilities in the airport have been overloaded.
The traditional 150 MHz analog system of the airport missed many places in coverage. The radios in the system can carry out only the voice communication, and the anti-interference ability is not satisfying. Airport business departments, airlines, production units, and airport-stationed units have built their own communication systems. As a result, there is no unified command and control system or unified emergency command channel, so apron command often loses charge of the whole situation.
The rapid response of communication systems cannot be realized in this case, which greatly affects the security and efficiency of airport operation. It is urgent for the Huanghua International Airport to establish a private network communication system of multimedia integration and unified dispatch to ensure operation safety.
In order to solve this problem, Changsha Huanghua International Airport has adopted the broadband-narrowband convergence solution based on 400 MHz digital trunking, including 400 MHz digital trunking system and 4G broadband network applications.
Now, the system monitors the landing time of aircrafts in real time and automatically informs the staff of tasks via the APP running on the multi-mode advanced radios. The staff can be ready 15 minutes before landing. The built-in 400 MHz trunking module of the multi-mode advanced radio ensures mission-critical voice communication in real time.
