Nanjing Metro in China is one of the fastest growing metro network in the country and serving a population of more than seven million people. The city invested in a new tramline and in the expansion of its metro system.
In seeking a solution to improve its safety and security, the Nanjing Metro Corporation selected operational telecom networks from OTN Systems, a leading developer of high-end multi-service networks for metros, light rail systems, people movers and railways worldwide.
The Metro Public Security Network backbone is a private network and is key in assuring security of all passengers and metro personnel and serves a number of benefits:
- CCTV plays a main role in this. Checking for / recognising of suspicious persons, packages and behaviour plus pickpockets and other criminal or anti-social activity. The huge number of safety cameras demand high and efficient use of the bandwidth and easy control
- The network will allow the Nanjing Public Security Bureau to distribute contact information of police officers, information on lost & found property, emergency alarm information, etc. to all metro stations
- The network is also used as backbone for the wireless police trunked radio system, which allows metro police officers to communicate to the police headquarters
- Also the network itself is fully safe, so it is impossible to hack this network and the different applications simply cannot impact each other. The network itself is a standalone network
Therefore the backbone network needs to be highly reliable and fully secure with large bandwidth. The OTN Systems flagship product OTN-X3M (Open Transport Network), with a transport capacity of 10G and its unique SLAN function perfectly complies with these requirements.
This year, Nanjing has expanded its metro network with three new lines (L10, S1 and S8) and has also added a new tram line in the Qilin Technological Innovation Park. OTN network products are currently installed along all existing metro lines and the tram line in Nanjing. All new and planned metro lines will additionally rely on OTN Systems to get their information across.
Over the last 20 years, OTN Systems has built a solid reputation deploying cost-effective and reliable communication networks worldwide. Nanjing L1 has already been operational for more than nine years and L2 for more than four years, while giving full satisfaction to the customer. As a result, Nanjing continues to select OTN Systems to build its communication networks.
