At present, the TETRA system is widely used due to its complete command and dispatch functions and flexible networking methods. After successfully serving the Beijing Olympic Games and Guangzhou Asian Games, TETRA once again guaranteed the Universiade, providing digital trunking communication services for the opening ceremony, Universiade security, traffic command, power supply guarantee, radio monitoring, vehicle scheduling, medical ambulance, urban operation management, etc. It provides a powerful communication guarantee for the success of the contest. At the Universiade, the TETRA system became one of the heroes behind the success of the Universiade.
In recent years, the TETRA system has been widely used in urban management functions such as transportation, government, and public security dedicated systems. This professional mobile communication system has begun to receive attention and its application potential has been gradually tapped. It is not difficult to imagine that in this development process, and even in the future, companies with professional technical advantages and rich experience will become leaders in this field.
Regarding TETRA's role in major events, European aerospace defense group Cassidian (hereinafter referred to as "European Aerospace Cassidian"), a provider of Shenzhen's 350MHz digital trunking network, believes that "for major events like the Universiade, professional digital trunking communication networks have It is important for the core role of security communications and competition command. "Said Zhang Shaohong, CEO of Cassidian China.
In addition to the emergency communication system, Cassidian also provided the TETRA network for Shenzhen Metro. The network covers all 5 lines of the Shenzhen Metro. Not only is it the first in the domestic metro area in terms of interconnection, but also has many world-leading functions in the application of TETRA system, such as support for VPN virtual private network function, each line Communication can be scheduled independently; it supports the recording function of the whole network, and can realize the dynamic recording of individual calls and group calls in the whole network. These ensure the safe operation of Shenzhen Metro.
Create the nation's largest 350 trillion digital trunking network
Shenzhen 350 trillion emergency command digital trunking network is not only the largest 350 trillion TETRA network in China, but also the first system in China that has fully integrated the digital trunking network and the command center system. Such as 110/122/119 police system integration, automatic vehicle / person location system, network-wide recording system, automatic auxiliary dispatch system, short message center system, WAP data query system, integrated network management system, etc. This is also the first urban emergency command digital trunking system built by the public security system in China and shared by multiple departments. It is understood that during the Universiade, there were about 30,000 professional users from the municipal party committee and municipal government, the Universiade Executive Bureau, the public security, emergency response office, foreign affairs office, traffic control, firefighting, armed police, border defense, non-commissioned, power and other departments.
During the Universiade, Shenzhen ’s 350MHz emergency command digital trunking network achieved outdoor coverage of Shenzhen, suburban plains, major highways, and important tourist attractions, as well as coverage of 41 competition venues, 22 training venues, and Universiade official hotels , And meet the coverage requirements along the road connecting with the airport, Luohu Railway Station and other hot spots.
According to reports, the TETRA network provided by European aerospace Cassidian includes the EADS next-generation switch DXT3, the 350-megabyte base station TB3 and the dispatch system. It adopts a highly disaster-tolerant backup design at all levels, including the system layer, network element layer, and transmission layer. "This is currently the 350 megabyte digital trunking network with the highest security and reliability in China, and it is also the largest 350 megabyte digital trunking network in China." Zhang Shaohong said.
Behind the "zero failure"
Whether it is abroad or domestic, it is very important to ensure the safety and smoothness of communication in some important government activities or international events. However, due to the large number of participants and the complex network environment, it is very difficult to achieve "zero failure", especially the requirements for system equipment are nearly harsh. However, this does not seem to be difficult for the European aerospace Cassidian.
It is understood that during the Universiade, there were about 30,000 professional users from the municipal party committee and municipal government, the Universiade Executive Bureau, the public security, emergency response office, foreign affairs office, traffic control, firefighting, armed police, border defense, non-commissioned, power and other departments. The whole day traffic load at the opening ceremony was the highest since network operation. The number of wireless network calls reached 1.84 million, and the number of calls during busy hours reached 140,000. The European Aerospace TETRA system achieved "zero failure" operation.
Obviously, this is not the first time that the European Aerospace Cassidian TETRA system has achieved "zero failure" operation in major events. At the previous Beijing Olympic Games and Guangzhou Asian Games, the European aerospace Cassidian TETRA system was operating with "zero failure", giving the event a strong communication guarantee.
It is not accidental that Cassidian of European Aerospace can participate in the communication guarantee of the Universiade cluster again. In fact, from the Beijing Olympic Games, Guangzhou Asian Games, European Aerospace Cassidian has accumulated rich experience in TETRA system construction, application and communication support services for large-scale events, and formed a set of rigorous and efficient large-scale event service solutions. This accumulation of experience will help Cassidian of European Aerospace to participate in more international large-scale events.
According to reports, since the launch of the Universiade guarantee project in March, the experts of Cassidian of European Aerospace have prepared 16 major 120-item system rehearsal test items for the Universiade guarantee, and conducted repeated exercises and continuous improvement to ensure the quality of on-site services.
"Since the start of the safeguard project, our experts have really implemented every detail, surveyed every site on site, and traveled 20,000 kilometers." For the key factors for success, Zhang Shaohong believes that there are four main aspects: First, safety, stability, and function Strong network; 2. Expert team with rich experience in supporting large-scale events; 3. Detailed and comprehensive support programs and exercises; 4. Sincere cooperation of partners.
If we simply summarize, we can find that the accumulation of technology, experience and partners is becoming an inevitable trend for a company to succeed.
It is understood that after the successful acquisition of Nokia Digital Trunking Communication Division and PlantCML, the largest command center provider in North America, European Aerospace has become the largest digital trunking provider in Europe due to the improvement and improvement of product and business capabilities. As of now, Cassidian has provided more than 200 large digital trunking networks worldwide, including 30 national public safety and government networks.
