Hytera Gives Kazakhstan Railways A Digital Boost

Nur-Sultan, Kazakhstan – September 1, 2022 – Kazakhstan Temir Zholy (KTZ) has

awarded Hytera (SZSE: 002583) the contract to upgrade its communications system to a

Terrestrial Trunked Radio (TETRA) system capable of transmitting both voice and data along

3,600km of railway track, around 20% of the railway giant’s network.

KTZ is the national railway company of Kazakhstan. It is responsible for developing, operating and maintaining the country’s railway transportation network. The railway links China to Europe and has been handling a growing flow of goods since 2013.

To increase transport capacity and enhance train safety, KTZ needed to modernize its radio

network and implement a new centralized dispatch center.

After intensive research on available options, the KTZ decided to upgrade to a TETRA system.

Hytera, a leading global provider of professional communications technologies and solutions, was entrusted with the responsibility of fulfilling the project from system design and equipment manufacturing to network deployment.

The project comprises a total of 72 TETRA base stations, 2,500 TETRA devices, over 80

TETRA & LTE multi-mode devices, 450 train-borne TETRA terminals, and more than 1,100 stationary and mobile TETRA terminals.

For Hytera, the major challenge involved providing reliable coverage over very long

distances along the railway lines. This meant deploying robust radio infrastructure able to

cope with harsh desert conditions and high altitudes.

In addition, the TETRA standard has not been used to support train safety systems before, so Hytera had to develop a highly reliable solution capable of supporting the necessary data applications.

The use of TETRA enabled a single radio ecosystem to be deployed for almost all of the

required applications, including data transmission for the train safety system. This made the

system simpler to design, install and maintain, as well as being more cost effective.

Partnering with railway communications provider, RTEL Group, Hytera developed a range of

innovative ways to deploy the system.

The safety system controlling the distance between trains will allow KTZ to operate more

trains on a given section of track at the same time, which will increase the amount of freight

the railways can handle.

Hytera also deployed broadband technology to support video for monitoring and emergency

response purposes.

"We are proud to offer KTZ a comprehensive solution from data transmission, track to train communications and staff dispatch,"

said Ivan Wang, Sales Director of Hytera Kazakhstan.

"This is an exemplary project demonstrating how TETRA can deliver reliable and efficient

voice and data transmission services in a cost effective way. In addition, the incorporated

broadband features will further enhance situational awareness in emergency situations."
