Why ACU-Pro 5G Automotive?
Seamless 5G upgrade path:
Identical form factor and electrical interfaces as ACU6. OEMs can upgrade existing vehicle models to 5G without chassis or harness redesigns. Direct porting support for services implemented on previous generation TCUs.
Optimized certification path:
Leverage ACTIA's existing STU approvals to significantly reduce certification costs and timelines. Pre-verified peripheral components — including eCall speakers and external antennas — guarantee passing radio and functional tests on the first attempt.
Regulatory compliance, built in:
Full support for Next Generation eCall (5G) with backward compatibility for Pan-European eCall. Pre-compliant with UN-R155 (Cybersecurity) and the RED directive.The cellular modem is compliant with US and China connectivity regulations (BIS), simplifying global vehicle homologation.
Minimized NRE & rapid time-to-market: ACTIA carries the cost for global radio certifications using standard antennas — saving customers significant development costs and months of testing. COTS hardware strategy delivers off-the-shelf cost benefits with full flexibility for custom OEM application software.
Advanced connectivity & split billing: Support for split billing enables OEMs to separate mission-critical vehicle data from passenger infotainment data. Global single SIM solution simplifies logistics across all markets with one managed MNO/MVNO provider.
Full E2E ecosystem:
Complete support for OTA software updates, remote diagnostics, anti-theft systems and remote convenience features such as climate control and remote lock/unlock.
Engineering partnership:
More than hardware — ACU-Pro 5G is backed by ACTIA's R&D integration services. Expert software integration into the customer's specific vehicle architecture and electrical network.
Wireless:
Full 5G Sub-6GHz. WiFi 6 (802.11ax) on 2.4, 5.0 and 6.0 GHz. Bluetooth 5.3*. GNSS. RF ports for external antennas (except Bluetooth) with GNSS phantom feed. Internal antennas for LTE1 (LTE2, WiFi and GNSS internal antennas prepared).
Network:
Ethernet 1000BASE-T1 port (TC10). Two CAN FD interfaces.
Applications:
New Generation European eCall. Vehicle tracking. Internet access (through Ethernet and WiFi hotspot). Additional services implemented on request.
*This product is currently under development and is intended to support Bluetooth wireless technology, yet not placed in market. Final Bluetooth qualification will be completed prior to commercial release.
Upgrade:
Software download is supported via the electrical network/s and 'over the air' via the cellular or WiFi radio link.
Supply:
Compatible with 12V systems. The optional battery ensures that critical functions continue if the main supply is lost and ensures clean shutdown and network de-registration.
Subscription:
eUICC – Connectivity subscription setup is pre-loaded with 'multi-IMSI profile'. Customer SIM can be used.
Processing:
System operation managed by a dual core 'system on chip'. Each 64-bit ARMv8-A Cortex-A35 core offers 2800 DMIPS. LP-DDR4 RAM 1 GByte and 8 GByte eMMC as standard (both can be scaled upwards).
Security:
Secure boot supported. Data security is ensured by use of a 'trusted execution environment' and 'signed software'.
Electrical interfaces:
Generic setup: Main supply. Speaker output. Microphone input. eCall buttons with illumination. Crash signal. Dual CAN.
Internal sensors and indicators:
XYZ-axis accelerometer and gyro. Three LEDs (1 x Red, 1 x Blue, 1 x Green). Temperature sensor.
