Equipment Description and Intended Use:

ConBox 2020RD NA a connectivity box for vehicles with features like e-Call, WiFi, Bluetooth, and GNSS. It includes a backup battery, and integrates with vehicle systems via CAN, Ethernet, and A2B.

Intended Use

Emergency Calls: The e-Call functionality allows vehicles to automatically contact emergency services in the event of an accident, enhancing passenger safety..
Wireless Communication: Supports WiFi and Bluetooth allowing for various wireless communication needs within the vehicle.
Audio Communication: Manages voice calls with integrated microphones and speakers.
GNSS Tracking: Provides real-time tracking of the vehicle’s location.

Main Capabilities

LTE Connectivity
GNSS (GPS, Glonass, Beidu)
Pan-European ECALL

TPS ECALL
ERA GLONASS Emergency Call
Vehicle Tracking for Antitheft function

Bluetooth
WI-FI

ConBox2020RD NA is enabling the vehicle to have Mobile Network connectivity, and self-localization capability, that enable in turn several services, like emergency call (pan European, Private, Russian one), vehicle tracking for antitheft function.
ConBox2020RD NA is relying on a primary and a secondary external LTE antennas, plus an internal one, and external GNSS antenna. This architecture allows to have the best RF performances, with the possibility to rely on a backup solution, when, in case of emergency, external antennas are not any more available.

Software version : 0340

Product Variants

The ConBox 2020RD NA has several variants to cover all necessary markets. The differences rely on three essential parameters:

The type of NAD (European, North American, or Rest of the World)
The embedded SIM card

The presence of the VTS (Vehicle Tracking System) function, which requires an accelerometer and a larger backup battery on board.
