Communications

Novariant autosteering solutions are capable of utilizing the data from a variety of both wired and wireless communication technologies. Communication between vehicles and infrastructure will be key as we move towards the realization of autonomous vehicles in civilian, industrial and agricultural markets.

By implementing wireless communication mechanisms in self-driving cars to exchange vital safety and emergency information between moving vehicles, most accidents will be preventable. Cooperative Systems can be established by implementing Novariant's superior autosteering and braking solutions with the communication mechanisms vital for exchanging information between moving vehicles to improve safety and prevent accidents.

In industrial and agricultural applications, Novariant solutions can help wirelessly transfer guidance lines, coverage maps, tank levels and yield data between multiple vehicles. Operators in the same area will be capable of sharing information in real-time to minimize overlap and rework as well as optimize safety.

Wired Communication


Serial - Serial interface is a connectivity by which a device sends data one bit at a time for communicating to another device. Novariant's GPS-based autosteering controllers can communicate with the GNSS smart antennas and the cellular modems via serial interface.


USB - Universal Serial Bus (USB) is an industry standard developed that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. Novariant's controllers support USB interface for connecting with sensors and cameras as well as for connecting with flash drives for firmware upgrade or for data transfer.


Ethernet - Ethernet is a family of computer networking technologies for local area networks (LANs). It is a computer industry standard for connecting a number of computer systems to form a local area network, with protocols to control the passing of information and to avoid simultaneous transmission by two or more systems. Novariant uses ethernet to connect displays, cell modems or routers with Novariant's autosteering controllers. Two Novariant controllers can also communicate with each other using ethernet.


CAN - CAN (Controller Area Network) bus is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. The devices that are connected by a CAN network are typically sensors, actuators, and other control devices. Novariant's autosteering controllers can electronically communicate with implements, tractors and vehicle computers via CAN bus using the universal ISOBUS protocol. The CAN interface will be also used for communicating with Virtual Terminals. GNSS data, with NMEA 2000 protocol, can be transferred to the Novariant's autosteering solutions via CAN bus. Also, the sensors can communicate with Novariant's autosteering solutions using the CAN interface.


FireWire - FireWire is a technology that allows high-speed communication and data exchange between a computer and a peripheral or between two computers. FireWire is used as the method for transferring information between digital devices, especially audio and video equipment. Novariant can use FireWire technology for connecting with high-speed cameras.


Wireless Communication


Wi-Fi - Wi-Fi is a protocol standard for short-range wireless communications with low power consumption. Wi-Fi is the wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. Wi-Fi is directed at computer-to-computer connections as an extension or substitution of cabled networks.

Novariant controllers include embedded Wi-Fi modules and can receive updates when in the range of an access point. They can upload and download data (e.g. performance data and prescription maps) using the Wi-Fi technology. Wi-Fi can be also used for vehicle-to-vehicle communication (V2V) for exchanging vital safety and performance data, when two vehicles with Novariant autosteering solutions are located within a short distance of each other.

Novariant controllers also utilize Wi-Fi as the mode of communication for the revolutionary SimpleSteerâ„¢ autosteering tablet application. SimpleSteer is a high-precision autosteering display solution for precision agriculture that runs on a consumer tablet device. The SimpleSteer software and Wi-Fi solution from Novariant converts a consumer tablet into a wireless command post for advanced autosteering operation of vehicles including tractors, combines and other farm vehicles.


Bluetooth - Bluetooth is a protocol standard for short-range wireless communications with low power consumption. Bluetooth is known for exchanging almost all types of data such as text and multimedia. Bluetooth-based applications are primarily in computer peripherals as well as in some wireless remotes or gesture controlled devices. Novariant GPS-based steering solutions can receive the GNSS data via Bluetooth. Bluetooth is also the standard wireless connection between consumer devices and the infotainment stack unit of a vehicle.


ZigBee - ZigBee is a protocol standard for short-range wireless communications with low power consumption. ZigBee consumes significantly less power than Bluetooth technology. ZigBee devices can be networked in star, mesh and other generic topologies: more than 65,000 cell nodes can be connected together. ZigBee protocol is primarily used for communicating with devices that are smaller in size and consume less energy such as TV remote controls. Novariant controllers can use Zigbee communication for wireless networking with sensors.


Cellular - Wireless communication through embedded cellular connectivity is finding its way into all markets including in precision agriculture, construction, automotive and robotics. OEMs are increasingly using embedded cellular for safety and diagnostic purposes, since the built-in wireless connectivity is more robust.

Novariant controllers can connect to the outside world via embedded or external cellular wireless modems with CDMA or GSM systems including 3G, 4G, 4G LTE, 4G Evolution. The cellular communication can be used by Novariant autosteering solutions for different applications including remote diagnostics, remote services, telematics, software upgrades, uploading data such as the performance information and downloading data such as the prescription maps. Cellular technology can be also used for safety or performance improvements in vehicle-to-vehicle or vehicle-to-infrastructure communication. In the precision agriculture industry, the combination of autosteering and cellular technology is used for automatically positioning grain carts alongside moving combines.


DSRC - Dedicated Short-Range Communications (DSRC) is a two-way short-to-medium range wireless communications capability that permits very high data transmission critical in communications-based active safety applications.

In the automotive industry, cooperative intelligent transport systems use both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications to enable cooperation between vehicles and road infrastructure to achieve improvements in the areas of safety, mobility and the environment. One of the communication technologies used for these applications is DSRC. Communication-aided adaptive cruise control (ACC) is a potential application for Novariant's advanced autonomous steering in combination with V2V and V2I via DSRC.
