BNEX V2X · V2V and V2X communication for Indian roads
V2X communication that shares intent.
Sensors let a vehicle see. BNEX V2X lets it tell. One module shares what a vehicle is about to do with every vehicle, signal and system around it — before anyone can see it happen.

- Oct 2028 V2V mandatory on every new vehicle in India (draft)
- C-V2X 5.9 GHz PC5, built for AIS-230
- Zero frames written to your vehicle bus
01 · Why now
The regulatory timeline.
From October 2028, under the draft rule, every new vehicle made in India must be able to talk to the vehicles around it. Not a premium feature. Every vehicle — two-wheelers, cars, trucks and buses.
- Jun 2026 DoT exempts approved C-V2X devices at 5.875–5.905 GHz from spectrum licensing
- Aug 2026 MoRTH publishes the draft V2V rule under AIS-230
- Oct 2027 Vehicles fitted with V2V must comply with AIS-230
- Oct 2028 V2V fitment mandatory in all new L, M and N category vehicles
OEMs lock V2X designs and suppliers through 2027 to ship compliant vehicles in 2028. That window is open now.
Draft notification amending CMVR 1989, MoRTH, 3 August 2026. Final notification awaited. C-V2X equipment at 5.9 GHz requires type approval.
02 · Intent, not just position
Intent, not just position.
Most connected-vehicle systems report where a vehicle has been. BNEX V2X reads the signals that carry a driver's intent the moment they appear on the vehicle bus, and shares them in standard V2X message semantics — so the vehicles around it learn what is about to happen, not what already did.
- Brake pedal & ABS
- Steering angle
- Yaw rate
- Indicators & hazards
- Brake lamps
- Accelerator
- Gear & reverse
- Speed
- Parking brake
- Warning lamps
Signal set justified by ETSI CAM/DENM and SAE J2945/1. The VIN is never placed in a V2X message.
03 · What becomes possible
V2V · Vehicle to vehicle
A hard brake ahead reaches you before you can see it.
When a vehicle brakes hard, its module raises an emergency-brake warning on its own and broadcasts it. Vehicles behind receive it in milliseconds — even when the braking vehicle is hidden behind a truck, a bend or a wall.
Every module shares position, speed, heading and intent ten times a second.
V2I · Vehicle to infrastructure
The traffic light joins the conversation.
Signals, gates and loading docks broadcast their state and their hazards to every vehicle in range. A driver knows the light will hold green, or that a gate is closed, before reaching it.
V2C · Vehicle to cloud
One vehicle sees the accident. Every vehicle knows.
A hazard reported by one vehicle is relayed to vehicles on that route far beyond radio range, so traffic slows and reroutes before it reaches the scene.
04 · Built for Indian roads
Built for Indian road conditions.
Global V2X was built for orderly traffic, wide lanes and large vehicles. India is two crore two-wheelers a year, mixed traffic, and density that breaks the assumptions underneath every protocol designed elsewhere.
Precise relative positioning
GNSS alone is off by metres — enough to put a scooter in the wrong lane. We fuse GNSS with an on-board IMU so a small, tilting, weaving vehicle is placed where it actually is. Most cost-optimised modules drop the IMU. Ours does not.
Density, not sparsity
In Indian traffic the problem is not reaching a distant vehicle; it is deciding which of a hundred nearby vehicles matter. Our relevance and congestion logic is built for that case first.
Designed and built in India
The stack is ours top to bottom, so a requirement change becomes firmware work rather than a vendor negotiation across a time zone.
05 · For OEMs
Compliant vehicles ship in 2028. Designs lock in 2027.
If you are building for AIS-230, the work starts now. We run structured pilots with OEMs and fleet operators, on their own vehicles and their own sites, and take the results into AIS-230 preparation.

06 · Inside the module
The module, part by part.
06 · How it sits on the vehicle
Read-only vehicle integration.
- Automatic bus detection: J1939 and OBD-II (ISO 15765-4), 11 and 29-bit, 250 and 500 kbps
- Hard-brake warnings raised from vehicle data, with no driver action
- Listen-only by default: zero frames written to any ECU
- Hazard warnings delivered inside the 100 ms safety budget
- No VIN in any V2X message
- Works the same on trucks, buses and cars
07 · Where this goes
From shared position to shared perception.
The mandate gets a radio onto every vehicle in India. That is the beginning, not the product.
- Shared position. Every vehicle broadcasts where it is and what it is about to do. This is what AIS-230 requires, and what ships in 2028.
- Shared perception. Vehicles pass on what their sensors see, compressed into compact machine-readable form so the network carries understanding instead of raw data. A vehicle with little intelligence of its own draws on the intelligence around it.
- A shared world model. A live picture of Indian roads, built by the vehicles driving on them — how traffic here actually behaves, learned from the only place it can be learned.
We are building the layer that lets what a vehicle understands travel. Be in the stack of every vehicle in India.
08 · FAQ
Questions about V2X and V2V.
What is V2X, and how is V2V different?
V2X (vehicle-to-everything) is communication between a vehicle and everything around it: other vehicles (V2V), roadside infrastructure such as traffic signals (V2I), pedestrians (V2P) and the network or cloud (V2N). V2V is the vehicle-to-vehicle part, where vehicles broadcast their state and intent directly to each other. BNEX V2X covers V2V, V2I and V2C scenes.
What is the difference between C-V2X and DSRC?
C-V2X (cellular V2X) is a 3GPP standard. Its PC5 sidelink lets vehicles communicate directly, without a mobile network, and it can also use the cellular network. DSRC is the older technology based on IEEE 802.11p Wi-Fi. India's draft AIS-230 specifies C-V2X on-board units.
Is V2V mandatory in India?
Not yet. On 3 August 2026 the Ministry of Road Transport and Highways published a draft notification amending the Central Motor Vehicles Rules, 1989. If it is approved as drafted, V2V fitment becomes mandatory on all new L, M and N category vehicles (two- and three-wheelers, cars, buses and goods vehicles) made from 1 October 2028, and vehicles fitted with V2V from 1 October 2027 must comply with AIS-230. The final notification is awaited.
What is AIS-230, and which frequencies does it use?
AIS-230 is the draft Automotive Industry Standard for V2V on-board units in India. It sets minimum technical, functional, performance, environmental and cybersecurity requirements for factory-fitted C-V2X units in the 5.875 to 5.925 GHz band. In June 2026 the Department of Telecommunications exempted approved on-board units at 5.875 to 5.905 GHz from spectrum licensing. Equipment type approval is still required.
What is BNEX V2X?
BNEX V2X is BharatNex's vehicle-to-vehicle communication module and software stack for Indian roads. It reads the signals that carry a driver's intent from the vehicle bus, such as braking, steering, indicators and hazards, and shares them as standard V2X message semantics, so the vehicles around it learn what is about to happen, not only where a vehicle has been.
Is BNEX V2X AIS-230 compliant?
BNEX V2X is built for AIS-230, but BharatNex does not claim certification. AIS-230 is a draft standard and may change. BNEX V2X is in development as a C-V2X (PC5) module at 5.9 GHz for AIS-230; current development and demonstration units run the BharatNex sidelink stack on licence-free spectrum, and production units require equipment type approval.
Does BNEX V2X write to the vehicle's CAN bus?
No. The integration is read-only: BNEX V2X listens to the vehicle bus and writes zero frames to it. The vehicle identification number (VIN) is never placed in a V2X message.
Does V2V replace radar and camera ADAS sensors?
No, they complement each other. Cameras and radar see what is in line of sight. V2V adds what a vehicle is about to do, including events hidden behind another vehicle or around a corner, so a hard brake ahead can reach the vehicles behind it before their sensors can see it.
