ATDI Poland - Updates

March 29, 2023

If ATDI were the air force, their Polish team would be likened to a stealth fighter. Often flying quietly under the radar, this multi-disciplined team covers sales and business development for Poland and Eastern Europe, as well as development services and expertise for consultancy projects across the group. This month we look at some of their recent projects. 

Latvia Regulator, VASES chooses HTZ Communications

Latvian frequency management authority VASES turned to ATDI to enhance their spectrum engineering capabilities, focussing on radio spectrum compatibility and coexistence coordination. 

HTZ Communications enables VASES to undertake complex technical analysis ensuring fair and efficient spectrum use by minimising the impact of in-band and out-of-band interference and automating frequency allocations to improve efficiency and spectrum reuse.

GSM-R planning for Polish National railways

To support the ongoing rollout of this project, the ATDI team provided a radio network plan for a proposed new line between Wrocław and Łódź, as part of the CPK Centralny Port Komunikacyjny (Central Transport Port). 

The team used the prospective planning function in HTZ to determine the best locations for stations, optimising them to ensure the network met the EIRENE requirements along with various considerations; obstructions including forests and existing buildings, radio coverage extending to the service roads on both sides of the railway line, the impact of the network on the local population to reduce electromagnetic exposure and the management of environmental factors such as the protection of floodplains, safeguarding protected areas (stork breeding grounds) and other historic areas.

Polish Naval Academy

The Polish Naval Academy uses HTZ Warfare to model the impact of wind turbines on radars. The academy enables students to identify interference from the turbine blades on radars, communications, and radiolocation systems for the frequencies 30 MHz to about 10 GHz.

The students learn how to model the effects of radio shadowing and the impact of false radar echoes. HTZ models the effective reflectivity surface of the radar (RCS) and the scattering coefficient, accounting for the attenuation of waves in free space (measuring the signal drop as a result of reflections on the rotor blades back to the receiver).
