Making connections with TETRA
t the time when IMPA decided to commission a new public safety communications network, only one manufacturer, Motorola, had ever delivered TETRA networks for public safety customers in South Korea. A competitive tender led to several alternatives being proposed. And in a break from convention, IMPA chose the Spanish manufacturer Teltronic to supply its TETRA infrastructure. This introduction of a competing manufacturer within the Korean police market created a particular challenge for the winning bidder because the new Teltronic network was required to interconnect with existing Motorola TETRA systems in neighbouring jurisdictions. However, an in-depth study carried out by the supplier and the system integrator enabled an interface solution to be developed. This has been very successful in allowing TETRA to demonstrate its multi- vendor support and to become the sole secure communications standard in Korea.

including a number of special installations for police motorcycles supplied by Teltronic. Taking advantage of TETRA’s robust interoperability process, IMPA has obtained terminals from both Teltronic and the UK supplier Sepura. While most police networks in Europe operate in the ex-
NATO 380–400 MHz frequency band, the Incheon police network runs at 800 MHz. A TETRA network at 380–400 MHz does exist in South Korea; it is operated by a utility company. Following the award of the Incheon Police contract to
Teltronic, IMPA awarded the maintenance contract for the system to Teltronic’s Korean partner, Withus.

Securing the summit Te G-20 summit was a national event of exceptional importance to South Korea’s reputation as a rapidly developing, advanced economy. VIPs from 33 countries attended the meeting. Heads of state, ministers, business leaders and others passed through Incheon International Airport on their way to and from it. All these dignitaries needed to be escorted through the district of Incheon to the main venue for the summit, the COEX Convention
& Exhibition Center in Seoul. Meetings and related events conducted by high-level politicians and civil groups were also held in the Songdo New City area of Incheon itself. Some 800 police officers were required just for the
protection of VIPs. Teir orders were issued by the police commander through the TETRA network. If the wireless system had failed, the commander would have been held responsible, and would have been required to answer to the President himself. During the event, technical staff from Teltronic, Withus and IMPA were therefore on standby 24 hours a day. To handle the increased radio traffic, the number of TETRA radio carriers was increased across the network. Tough the main event occupied just two days –
November 11–12, 2010 – tight security procedures were in force for days and even weeks beforehand. Using the expanded network, officers successfully policed a series of demonstrations which took place close to the main event location on November 7. Te network worked perfectly and has continued to provide faultless performance ever since. Further challenges now lie ahead for Incheon Police and
their TETRA network. Next year, representatives of 50 countries will meet in South Korea for discussions about nuclear proliferation and disarmament. And in 2014 the Asian Games are due to be held in South Korea. To cope with the increased radio traffic arising from these special events, it is likely that further TETRA sites will be built and more carriers added.
Rich applications Capitalizing on TETRA’s strengths as a technology to enhance police operations, IMPA collaborated with
Summit talks in Seoul T
he G-20 group of nations has emerged from the original G-7 and G-8 concept of the post
Cold War era to include a number of rapidly emerging nations such as China, India, Brazil, Indonesia and Mexico. Last year, Korea became the first Asian country and the first non-G8 nation to host a G-20 Leaders’ Summit.
The Summit took place on November 11–12 at the COEX Convention & Exhibition Center in Seoul. Taking as its main theme the G-20’s role in the post-crisis world, it focused on the global financial system and the world economy. Represented at the meeting were the European Union and 19 other countries.
