Wireless: How would you describe the current state of the TETRA market and Hytera’s position in it?Bernhard Klinger: TETRA is now and will be in the future the most important standard for PMR. The Americas market is growing especially fast and is in a state of constant movement. That is exactly where Hytera Mobilfunk comes in. Over the last few years we have had huge successes in South America. Recently we won contracts in Chile, Peru and Venezuela. These projects demonstrate not only Hytera’s leading position, but the fact that TETRA is still a robust and growing market.

How do you see the TETRA market developing?Hytera Mobilfunk has developed high end TETRA products ever since the standard was introduced. As we are very familiar with TETRA technology right from the start, we are convinced that it will remain the leading

technology for real mission and business critical users for at least the next decade.

We have noticed that customers are increasingly searching for a complete communication solution. Where reliable voice communication was the main focus in the early days of TETRA, today more and more data based applications support users in their daily work and help to optimise their processes.

TETRA Enhanced Data Service (TEDS) is the answer to a growing demand on data capability of TETRA networks and is part of the TETRA Release 2 extension to the TETRA standard. TEDS uses state-of-the-art modulation and coding schemes, fits in the existing frequency landscape and can be implemented today.

We want to focus on the growing North American market as it is the world’s largest PMR market. For almost two years now the Hytera team in America has included TETRA in its product portfolio. With this strong, highly professional and well established team we are very confident we can build on our recent success and make North America a significant TETRA market for Hytera.

What do you think Hytera has brought to the TETRA market? To sum it up, I would say Hytera has brought optimised solutions, cost effectiveness, powerful systems and radios tailored for the user. We believe one size doesn’t fit all when it comes to TETRA systems. With our tailored systems we offer the perfect solution for the user, as we always have his local conditions in mind.

We are happy to find suitable solutions that fit the actual site requirements. It is exactly this kind of ‘localisation’ that is one of our main strengths. A big advantage is also the broad variety of infrastructure, terminals, applications and accessories we offer. Instead of bringing several components from different distributors together, the user can get everything from a single source and won´t have any compatibility problems.

Working collectively with suppliers, partners and applications companies with the ability to squeeze greater value out of the investment and have a low overall cost of ownership makes Hytera quite unique in the TETRA market. Beyond this, Hytera continuously strives for the highest quality and innovative solutions. We have already implemented TETRA systems in more than 40 countries and different industries.

Can you outline the key benefits of the ACCESSNET-T IP system?ACCESSNET-T IP is very flexible in terms of system design. It scales well and can be

station. Besides offering best-in-class radio performance and high-end redundancy options our DIB-R5 is compliant with the TETRA Release 2 Standard. Using TEDS, the DIB-R5 offers an enormous bandwidth of up to 150 kHz RF. Its future-proof for demanding voice and especially data-applications; basically everything a user could possibly imagine.

But the TEDS functionality is not the only key feature of our DIB-R5. We really pushed our modular approach in developing this base station. Users have full front access to the individual components. Furthermore, the hot swop functionality allows an exchange of components in the operating system.

Besides the infrastructure components, applications are always of huge importance to users. This is the challenging part where the radio system is specifically tailored to customers’ needs and requirements.

Hytera’s approach is to offer our own high-end applications, but also to provide third party applications, that are highly specialised. Our multifunctional A-CAPI (ACCESSNET-T Common Application Programming Interface) enables partners to develop specific applications using this simple programming interface.

What are the advantages of the Hytera Network Management System?In a nutshell our network management system offers everything the user would need for network configuration, administration and maintentance. That of course includes the specific overview and management of each network element and all the subscribers within the mobile radio system.

Users only need to connect their computer to the radio system via IP and they can access the network management from anywhere. This is a huge advantage since users don’t need to travel around to set up or change configurations. The IP connection furthermore secures a robust and effective data transmission.

Our goal is to generate the highest benefit for our customers. I’m sure everyone who uses our network management system will agree that the features are very flexible and powerful and the interface is very user-friendly. For example, we offer different languages

deployed for small, rapidly deployable systems, as well as large, country wide installations. This gives our customers the ability to upgrade without restrictions. Our users especially appreciate the high network availability, communications security and application capacity of our ACCESSNET-T IP. It is really a TETRA mobile radio system that grows with the demands of its user.

The network structure is highly flexible and can be customised to local requirements. When it comes to both capital expenditure and operational expenditure the user can reduce costs, as the switching functionality can be completely distributed over the base stations.

Our base stations are already equipped with the processing power to provide interfaces and gateways for applications or external telephone systems. As one of the few TETRA manufacturers worldwide we offer the next generation DIB-R5 base station with leading edge TETRA Release 2 and TEDS capability.

Can you explain the benefits of the move to an IP-based system? Besides the broadband aspect IP offers many advantages compared with other technologies. Using IP as a backbone is very cost effective: users can access already existing IP infrastructure and the network is easy to expand because a leased line is not necessary.

Furthermore external services can be connected to the IP backbone at a glance. In the first place the flexibility of the system makes it obvious: it is the right system for customer-specific systems from small-scale plug’n’ play solutions right up to nationwide networks.

We have a very smart solution for extending existing E1-based ACCESSNET-T networks with new, IP based network segments. For example, our existing network for Macedonia delivered in 2008 was recently extended with additional, IP based base stations (see case study on page 4). By doing so we ensure the customer’s initial investment doesn´t get lost.

What are the main elements of ACCESSNET-T IP and what does that offer the customer?ACCESSNET-T IP solutions are highly customised to the users’ needs. Therefore, each component must guarantee best performance and flexibility. Our portfolio comprises of base stations, switching node, dispatcher, voice recorder and so on.

I am sure that Hytera’s infrastructure is proclaimed one of the best worldwide within the TETRA market for good reasons. One of the highlights definitely is our latest DIB-R5 base

for the user interface. The whole network management system is completely developed by Hytera Mobilfunk in Germany.

What do you think differentiates Hytera’s TETRA products from those of its competitors?Hytera has strong expertise and experience in implementing tailored solutions. Our TETRA systems provide secure communication, system availability, as well as multiple features like localisation, automatic call-group creation and comprehensive network management.

Having a very high transmitting power with up to 3W in combination with the very robust design, IP67 certification and patented antenna design makes the Hytera radios unique in the market. Other features such as GPS functionality and DMO mode are standard parts of our portfolio.

We manufacture and install TETRA systems and support our customers throughout the lifetime of our systems. All our products are developed under very high, German quality standards. This also means that our hardware and software is thoroughly tested before we ship and install our systems. “German Engineering” stands for our high level of reliability.

Can you give some idea of the Hytera TETRA infrastructure roadmap and potential migration towards 4G LTE?Public safety organisations in particular are investigating LTE as a basis for future broadband data standard for their applications. From today’s perspective it will still take several years until dedicated broadband spectrum will be available for public safety organisations in Europe and in other regions of the world.

Nevertheless, the combination of broadband technologies and TETRA is the next big technological step and will provide even higher data rates than we get from TETRA and TEDS today. Hytera is very close to the current PMR broadband standardisation work and is preparing to have the right products in time.

Private sectors like utilities, transport or oil and gas will probably have no access to dedicated broadband spectrum. A dual TETRA/commercial 4G terminal could be a potential short term solution to provide reliable mission critical voice services and non-mission critical mobile high speed data applications to the PMR users.

Hytera has already showcased interoperability between LTE and TETRA end user devices and is further investigating several approaches to bring broadband services to the PMR community.

The Republic of Macedonia is located in south-east Europe and includes an area of more than 25,000 km2. As a landlocked country with borders to five neighbouring countries, providing security is a high priority, particularly at the border regions.

For this reason, a uniform mobile radio system for the secure and effective transmission of voice and data was deemed essential for the country’s public safety organisations. An effective communication system is the basic prerequisite to securely coordinate task forces, particularly in emergency and disaster situations.

In 2009, Hytera Mobilfunk was appointed as main contractor for a project to deploy a TETRA mobile radio system throughout the country to enable up to 20,000 subscribers to communicate with each other. The solution also ensured that the Macedonian police, border patrol and employees of the Department of State reaped the benefit of its independent and interception-proof system.

Hytera’s initial installation in 2009 consisted of 42 DIB-500 TETRA base stations and two DMX-500 switching nodes based on its circuit-switched ACCESSNET-T system. In December 2013, Hytera Mobilfunk was awarded a second contract to expand the TETRA mobile radio system.

However, by this time Hytera had developed its IP-based TETRA system. Together with the local partner Saga Macedonia, Hytera Mobilfunk deployed 24 additional DIB-500 base stations and two IPN switching nodes of its new IP-based ACCESSNET-T IP technology into the existing TETRA mobile radio system.

Hytera’s technology is flexible enough to combine the existing E1-based, circuit-switched ACCESSNET-T system with its new IP-based TETRA technology. Both partial systems are managed using only one network management system.

A CS/IP bridge function ensures the coordination of the existing network management system with the new infrastructure for this combination. Each of Hytera’s network management systems is downward compatible via a software update.

The flexibility of Hytera’s equipment ensured that the customer saved money by not only

continuing to use the existing infrastructure, but also because of the minimal efforts involved in changing the network management database.

The transmission of data from the police and State Department imposed high demands on the flexibility and security of the mobile radio system. Hytera met the demands without any limitations. The highly redundant design also provided a maximum degree of reliability and availability of the network.

Authentication and dynamic encryption algorithms guarantee protection from interception. The mobile radio system is protected by the use of TEA2 encryption, which is the standard encryption level for public authorities in EU countries.

Hytera Mobilfunk’s mobile radio system has been installed on the 76km Marmaray rail project linking Asia and Europe under the Bosphorus straits in Istanbul

Istanbul in Turkey straddles the continents of Asia and Europe across the Bosphorus straits, which link the Mediterranean and the Black Sea. But while the million-strong metropolis has road links to bridge the straits, the two parts of the city are now being linked by a rail tunnel under the Bosphorus for the first time.

The ambitious Marmaray civil engineering project involves the construction of the railroad tunnel under the Bosphorus, along with the renewal of the rail line which runs along the Marmara Sea from Halkalı in Europe up to Gebze in Asia. The project gets its name of Marmaray by combining the name of the Marmara Sea with ‘Ray’, the Turkish word for rail.

Besides providing a long distance rail link between the Asian and European segments of Turkey, the aim of the project was to help reduce the extremely high traffic volume in the city of Istanbul and most particularly across the Bosphorus straits.

Up to 1.5 million people can pass under the Bosphorus in just a few minutes every day thanks to the new fast train connection, which has 40 stops along the line including three underground stations. The railroad operator required reliable and independent voice and data communication. Hytera Mobilfunk convinced system integrator SISTEM that its TETRA mobile radio system was the right solution for the job. In 2012, Hytera was contracted to implement its ACCESSNET-T IP radio system along the entire Marmaray project rail line.

Hytera’s TETRA system provides the radio communications for Turkish National Railroad (TCDD) subscribers both within the 1,387m long rail tunnel under the Bosphorus and along the existing railroad network, which is being generally upgraded as part of the Marmaray project.

The radio system supports not only staff personal mobile radios, but also in-cab mobile radios used to communicate between trains and control centres. Additional features of the Hytera system are the automatic login and

logout of the individual trains to and from the system, the passenger emergency call from the train and the automatic transmission of diagnostic messages from the trains to the central control.

The TETRA radio system is able to provide coverage along the whole length of the project whatever the terrain. Roughly one-third of the entire railroad line is underground, but the TETRA system is able to cope without any limitations. The solution ensures a high level of reliability and flexibility is provided, along with the ability to meet minimum bandwidth requirements.

Hytera Mobilfunk implemented an individually tailored ACCESSNET-T IP network. To ensure continuous mobile radio coverage, the company installed two base stations inside

the railroad tunnels, 27 base stations above ground and 11 indoor base stations to provide coverage at the railroad stations.

In addition, it provided two centralised IP nodes for switching and connection to applications and a comprehensive network management system (NMS).

The individual trains are directly connected with the mobile radio system using on-board units (OBRUs). A total of 110 of these OBRUs from ErvoCom are used for voice communication and transmit all types of information generated by the Marmaray project via the TETRA mobile radio system. Hytera has also supplied 60 PT580H hand portable TETRA radios.

An extensive suite of applications offer varied and user-friendly functions. The integrated network management enables a central and convenient network monitoring facility, as well as fast fault diagnostics and remedies from the workplace.

The ‘radio ground server’ application enables diagnostic messages to be uploaded to the maintenance management system using SDS messages. An external train dispatcher system with integrated voice recorder from Thales Deutschland (‘Norumat’) is used by the TETRA mobile radio system for effective data transmission. Both Hytera and external third party applications are efficiently integrated via Hytera’s multifunctional A-CAPI interface.

The TETRA mobile radio system is secured against breakdowns thanks to the installation of redundancy functions and equipment. Even under extreme conditions, such as the breakdown of entire locations, the whole mobile radio system continues to remain available and the performance is maintained.

Industry in South Africa uses TETRA ACCESSNET-T for voice and SCADA applications to ensure the safety of personnel and to monitor equipment

Due to the scarcity of petroleum resources, large coal-to-liquid and gas-to-liquid plants (CTL and GTL) were created in South Africa from the 1950s onwards.

The plants are used to produce fuels, as well as to provide basic materials for the chemical industry. The Sasol company is a market leader in this area with two large facilities situated in Sasolburg and Secunda in the Free State of South Africa in the North East of the country. Coal is exploited over a large area and partially highly explosion-prone substances are also processed. Given the nature of Sasol’s activities, it is essential for the maintenance of effective operations that a safe working environment and good monitoring of machines and personnel is provided. This requires a safe and reliable business critical communications system.

To ensure this, Sasol chose to install a Hytera TETRA mobile radio system at both locations. Hytera has been working with Sasol from 2006 to the present day.

Coal mining and processing in Secunda, as well as gas processing in Sasolburg, each consist of a complex sequence of different automated process steps. An error in one of these steps leads to an interruption of the processing chain and, as a result, to potentially enormous losses. Hytera’s ACCESSNET-T system is designed to offer employees a communication system with high voice quality for safe and efficient work.

For the employees in the harsh operational environments, Sasol made high demands on the

communication system, which Hytera was able to meet with a customer-specific solution.

Continuous availability of the network was a must-have, so extensive redundancy was built into the system elements to guarantee trouble-free, continuous radio coverage and capacity. The flexibility and technical performance of the system Hytera provided, even at peak loads, are a major highlight of the system’s capabilities.

Thanks to the multifunctional A-CAPI interface, external applications can be easily connected to the TETRA mobile radio system. In this instance, Hytera collaborated with its local partner Expert System Solutions (ESS) to provide a powerful SCADA (supervisory control and data acquisition) system at both locations. The SCADA system transmits the information via SDS using the TETRA infrastructure.

The four DIB-500 base stations at Sasolburg and 13 DIB-500s at Secunda are connected to the two DMX-500 switching nodes at both sites via ring structures. One challenge during the integration was the arrangement of the base stations. The possible locations outside of the hazardous areas were precisely calculated to enable optimal mobile radio coverage.

As a result, continuous mobile radio coverage is ensured over the entire 4,000km2 company site in Secunda. Both locations feature several base stations that are located outside of the company’s sites. This allows the network to reach employees, or the company’s own fire crew, who live outside the sites in emergency situations.

The mobile radio system at the larger of the two locations, Secunda, shows an enormous operational performance during peak loads: up to 52,000 calls are made every day. In this case, 8,900 subscribers, 800 call groups and 110 fleets are registered in Secunda.

In the process, different call priorities guarantee an effective communication that is tailored to the situation. As the communication demand increased, particularly during the annual maintenance period, Hytera has been continuously expanding and optimising the mobile radio system. A wide variety of different applications supplement the scope of the radio functions provided by the ACCESSNET-T system. Radio calls are recorded and played back using the TETRA voice recorder. For every recorded call, including the group calls, extensive information such as time stamp and subscriber information is stored on the network log.

The user-friendly interface and implemented search function enables users to call up previous connections. The AVL/GIS functions ensure an increased safety at the company site through the localisation of handheld and vehicle radios.

Following the deployment of a TETRA network for use by security forces and the organisers of the 2006 Asian Games, mobile network operator Ooredoo expanded the system for commercial use by local businesses

In 2006, the Emirate of Qatar on the Persian Gulf was the host for the Asian Games, an Olympic-level competition for the countries in the Asian region. For this major sporting event in which more than 10,500 athletes took part, Hytera integrated a secure TETRA communication system for the organisers and the security forces.

After the Asian Games, the mobile network operator Ooredoo engaged Hytera to expand the existing TETRA mobile radio system for commercial purposes.

Formerly known as Qtel Group, Ooredoo has a customer base of 96 million and reported revenues of US$9.3bn in 2013. Ooredoo delivers mobile, fixed-line, broadband internet and corporate managed services to consumers and businesses across markets in the Middle East, North Africa and southeast Asia.

Ooredoo wanted to expand the use of the TETRA mobile radio system by offering voice and data services to businesses and organisations in Qatar, looking for a secure two-way radio service.

Hytera’s robust solution is the world’s first nationwide TETRA mobile radio system to be used commercially, rather than specifically for public safety. The network now has over 27,000 registered subscribers and 250 customers.

The TETRA system in Qatar provides autonomous communication to numerous independent businesses via Ooredoo. User groups include businesses in the oil and gas industry, taxi businesses and airports.

The network is configured to ensure that the high service level requirements for transmission quality, reliability and capacity are met. It needs to be robust as it handles more than 250,000 calls daily, making it the world’s largest commercially used TETRA system.

Along with the high number of users, the high performance levels are also matched by the system’s adaptability. Around 2,600

independent call groups are configured on the network, each of which can demand different authorisations and network functions.

The flexible nature of the Hytera TETRA infrastructure offers Ooredoo security of investment and a future-proof technology, as it is easy to expand and upgrade.

Since 2005, Hytera has made several additions to the system and relocated network components. It has also implemented software upgrades under full load. The users did not

suffer any restrictions during ongoing usage as a result of these feature and capacity additions.

The Hytera TETRA ACCESSNET-T infrastructure comprises four switching nodes with 70 base stations connected to these nodes in a ring configuration. The comprehensive network management system provides efficient network monitoring even with high network utilisation. In addition, Ooredoo profits from the ability to provide straightforward and quick administration of users.

Extensive redundancy functions guarantee a high degree of reliability with back-up provided for network connections and control channels, along with additional geographic redundancy for the switching elements to ensure continuous radio operation.

One of the strengths of the Hytera solution is the way it enables the convenient integration of different applications. Customers are completely free as to how they use the mobile radio system, as well as what applications they choose to deploy on it.

The system allows for a high degree of adaptability with user groups assigned dedicated applications via the multifunctional A-CAPI interface. The largest user group, Doha International Airport (pictured above), deploys its own dedicated dispatchers and voice recorders, for example.

The TETRA mobile radio system offers Ooredoo a very high degree of flexibility with high network capacity and minimal maintenance costs. End users are guaranteed reliable, high quality, individual voice and data communications.
