Kazakhstan Railway Deploys Hytera TETRA System
Friday, May 20, 2022 | Comments

JSC "NC Kazakhstan Temir Zholy" (KTZ), the national operator of the main railway network of the Republic of Kazakhstan, plans to fully adopt TETRA digital radio communications as a standard.

To optimize the deployment of TETRA, Rtel adopted Hytera’s low-power consumption DIB-R5 Outdoor TETRA BS and Sinclair omnidirectional antennas, and developed a series of ways to deploy the system, such as a mobile “crown” with communication equipment, a removable drive to ensure the raising and lowering of the crown (equipment), and a cone-type mast with connection structures requiring no additional fasteners. This design removed the unnecessary passive AV units that reduce the output power of the base station. It also increased the safety of maintenance by minimizing the working at heights, as well as made the deployment seven times quicker than before.

Hytera offered a comprehensive solution based on the TETRA radio channels to prepare a data transmission environment and the centralized information processed from mobile (locomotives, SSPS, wagons) to stationary (depot stations) railway facilities. Besides, AMC Smartower with the mobile crown was developed specifically for Hytera DIB-R5 outdoor base station to improve workers’ safety and ensure the fast deployment of signal coverage.

Meanwhile, Hytera’s dual-mode PTC680 rugged radio, running on Android, has replaced various tech solutions by developing applications such as instrument and inventory control, personnel tracking and train approach notification while the Cybe-RR ecosystem expanded the technical capabilities of the digital infrastructure by solving security problems and worked as a single return center for information from all different subsystems.

Hytera’s TETRA coverage deployment along the railway tracks started in 2013. To date, about 20% of Kazakhstan's railways are covered by Hytera TETRA infrastructure, including 72 TETRA base stations, more than 2,500 TETRA devices, and more than 80 TETRA and LTE multimode devices, more than 450 train-borne terminals, and more than 1,100 stationary and mobile terminals.
