UCU 6.0-T – OBU with enhanced communication capabilities

The UCU 6.0-T is an on-board unit (OBU) with extended communication capabilities, designed for mounting on the roof or elsewhere on the upper part of the vehicle. In addition to V2X communication with junctions, it can also establish a connection with the control centre, transmit data within the depot and provide GNSS positioning to other vehicle components. All antennas are integrated beneath a plastic cover, eliminating the need for coaxial cables to external antennas. The unit complies with current standards for installation on public transport vehicles and rail vehicles.

Unit configurations

The unit is manufactured in various versions depending on the required configuration of communication modules. The specific set of interfaces is indicated by the unit’s designation, allowing a version to be selected precisely according to the project’s requirements.

Communication modules by version

• V2X module for communication with traffic light junctions – CAM, DENM and IVI messages, range up to 1.3 km
• LTE/5G module for communication with the control centre via a private APN without access to the public internet
• Wi-Fi (IEEE 802.11ax) for uploading and downloading data at the depot, with optional internet access for passengers
• GNSS module, which acts as a GPS server for the vehicle’s other components

Further features

• 1 × Ethernet port with PoE power supply
• CAN bus interface
• Sensors – gyroscope and accelerometer
• HSM module and provision for PKI registration, internal firewall, VPN access
• Type approval for railway vehicles

Sensors and security

The unit contains sensor circuits (gyroscope and accelerometer) suitable for future use, for example for detecting vehicle vibrations or acceleration. It is equipped with a hardware security module (HSM) for storing keys when communicating with the PKI and is ready for PKI registration.
