VEHICLE 5G GATEWAY

The vehicle network starts here.

The NSS Vehicle 5G Gateway connects every vehicle in the fleet to the 5G cellular network and distributes the onboard network over Ethernet and Wi-Fi to all onboard equipment — while acquiring data from the CAN bus and providing continuous GNSS positioning to the other systems.

Fleet connectivity and onboard backbone in a single unit.

The Vehicle 5G Gateway is each vehicle's connectivity and data entry point: it connects the bus (or other heavy vehicle) to the 5G cellular network, distributes the onboard network over Ethernet and Wi-Fi to the remaining onboard systems, acquires and decodes data from the vehicle's CAN/J1939 bus, and provides continuous GNSS positioning to the onboard systems — all managed remotely through a configuration interface in Portuguese.

The product combines an industrial 5G/Wi-Fi 6/Ethernet communications hardware platform, with a native CAN port, with a software layer of NSS's own. It is supplied and managed as a single NSS product: the base hardware comes from a third-party manufacturer, and the NSS layer (the NSS configuration interface, the CAN gateway and the GNSS positioning service) is clearly the part developed by NSS.

Key specifications

5G Release 16

Dual 5G modem with SA/NSA support and LTE FDD/TDD and WCDMA backward compatibility, dual-SIM (2× Nano-SIM) with e-SIM support for automatic switching between operators. Maximum NR SA throughput of 2.47 Gbps downlink and 900 Mbps uplink.

Wi-Fi 6

High-power Wi-Fi 6 (802.11ax, backward compatible with 802.11ac), 2×2 MIMO simultaneous dual-band (2.4 GHz + 5 GHz), in access point or client mode. PHY rate up to 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz.

5× Gigabit Ethernet

Five Gigabit ports configurable as LAN/WAN, with optional 48V PoE output to power onboard cameras and displays from the gateway itself.

Native CAN port

Acquisition from the vehicle's CAN/J1939 bus, with RS232 and RS485 serial ports for integration with legacy equipment.

GNSS positioning

Standalone multi-constellation GNSS positioning (GPS, GLONASS, BeiDou, Galileo, QZSS), with standalone horizontal accuracy better than 1.5 m CEP and velocity accuracy better than 0.1 m/s, NMEA 0183 protocol and a time-to-first-fix under 32 s cold, 25 s warm and 2 s on reacquisition.

Industrial environment

Operation between -40°C and +75°C, with native VPN support (OpenVPN, IPsec, WireGuard) and a NAT firewall with stateful packet inspection (SPI) for a secure link to the fleet management centre.

What runs inside the gateway

NSS configuration interface

A Portuguese-language web management interface, with NSS's own theme and navigation, for local configuration of the gateway — network, CAN and cellular link status on a single screen.

NCG — NSS CAN Gateway

Reads vehicle data in real time — speed, consumption, doors, among others — and makes it available to the remaining onboard systems.

GNSS positioning service

An NSS service that obtains the position from the gateway's GNSS receiver and makes the vehicle position available, in real time, to the remaining onboard systems.

Power, mechanics and certification

Power supply

Input voltage 10–55 VDC, maximum consumption 24 W. 3-pin GX12 connector (power + ignition/ACC control). Default 12 V / 2 A adapter.

Dimensions and weight

175 × 108 × 45 mm (L×W×H), 1.5 kg net.

Environment

Storage temperature between -40°C and +85°C, relative humidity up to 95%.

Antennas

4× FAKRA for 5G, 2× FAKRA for Wi-Fi, 1× FAKRA for GNSS.

CPU and memory

Quad-core processor at 1.8 GHz, 1 GB DDR3 RAM, 4 GB eMMC storage.

Certification and warranty

The base hardware (a third-party module) carries the manufacturer's CE, FCC and RoHS marking — the CE marking is confirmed by the module manufacturer's certificate of conformity. NSS does not issue its own Declaration of Conformity for the integrated product. 2-year warranty.
