Starting January 1, 2026 , connected V16 beacons will be mandatory in all vehicles in Spain. But a flashing light isn't enough: they must transmit their location to the DGT 3.0 platform in case of emergency.
To do this, they need a reliable communications network. This is where NB-IoT and LTE-M technologies come into play, specifically designed for connected devices like these beacons.
What is NB-IoT?
Narrowband-IoT (NB-IoT) is a low-power network technology built for devices that:
- 📍 They need to transmit little data, but in a very secure manner.
- 📡 They require coverage in difficult areas (rural, underground, tunnels, etc.)
- 🔋 They should work for years without maintenance
In the case of V16 beacons, this means reliable transmission of geolocation at any point on the road network .
What is LTE-M?
LTE-M is another low-power IoT network based on LTE. It's designed for mobile applications or those with higher data requirements.
Both technologies are permitted by the DGT, but:
- NB-IoT : increased range and signal penetration (ideal for beacons)
- LTE-M : Best for devices that move around and require more data
NB-IoT and LTE-M coverage in Spain
| Operator | NB-IoT | LTE-M | National coverage |
|---|---|---|---|
| Vodafone | ✔️ Yes | ✔️ Yes | Very high, including rural areas |
| Movistar | 🔸 Limited | ✔️ Yes | High in urban areas |
| Orange | ✔️ Partial | 🔸 In deployment | Expanding |
What network does the Hero Driver LED beacon use?
The Hero Driver LED uses Vodafone's NB-IoT network, the leader in IoT coverage in Europe. This enables:
- 📶 Transmit your location to the DGT from anywhere in Spain
- 🔋 Operate autonomously without the need for mobile coverage or apps
- ✅ Operate until 2040 without fees or renewals
What happens if there is no coverage?
Thanks to the nature of NB-IoT, it's highly unlikely that there will be no coverage on the road. It's designed to reach where other networks can't. Still:
- If there is no network, the beacon continues to function as a light signal.
- It will attempt to resend the location as soon as it regains connection.
Where can I buy a beacon with reliable NB-IoT connectivity?

Frequently Asked Questions
Can I find out if there is coverage in my area?
Yes. NB-IoT networks are already covering most of the country, especially with Vodafone.
Do beacons need SIM or data?
No. Connectivity is integrated by the manufacturer and does not require any additional contract.
What happens if I use an unconnected beacon after 2026?
It won't be approved, and you could be fined. Only connected ones are permitted by law.
