NB-IoT: A Technology Driving Efficiency and Innovation
Technology Serving Efficiency and Innovation
NB-IoT uses a narrow frequency band, allowing it to reach areas where other technologies fail, such as basements or densely built structures. This capability, combined with low energy consumption, makes it ideal for fixed battery-powered devices that are often hard to access and require minimal maintenance. These technical advantages enable NB-IoT to meet the growing connectivity and energy-efficiency demands of businesses and public entities.
The applications of NB-IoT are diverse, spanning multiple sectors. In smart cities, the technology can monitor real-time waste bin levels, regulate street lighting, track air quality, and manage parking space occupancy. “It is also used in telemetry, for instance in smart water, gas, or electricity meters. These devices automatically collect data, facilitating resource management and reducing the need for human intervention,” explains Julien Baudouin. In construction and building management, NB-IoT optimizes operations through sensors that monitor infrastructure conditions or closely track energy consumption.
A Strategic Choice
The solution offers several benefits, particularly in automation and cost reduction. First, it allows processes that previously required manual intervention to be standardized. For example, instead of manually reading meters or performing routine checks, NB-IoT devices automatically collect and transmit data, saving time and reducing human errors.
Financially, the sensors are generally low-cost due to the simplicity of the technology, yet they provide reliable performance. Furthermore, because these devices transmit minimal data, operational and infrastructure costs are reduced. Another key advantage is their low energy consumption, which decreases battery needs, extends device lifespan, reduces recharges, and lowers maintenance costs—supporting more sustainable and cost-effective use.
High Standards for Data Protection
Security, a critical concern for NB-IoT, is ensured through a strictly regulated cellular architecture. Unlike non-cellular methods such as LoRa, NB-IoT follows standards established by 3GPP, an international mobile technology standards organization. These standards guarantee high security through end-to-end encryption, device authentication, and other built-in protocols. “Unlike non-cellular solutions, NB-IoT integrates strict security protocols, making it particularly robust,” notes Julien Baudouin.
Telecom operators also play a key role in monitoring potential fraud or intrusion attempts in real time. This dual protection, structural and operational, makes NB-IoT a reliable technology for managing sensitive data in connected environments.
Integration with 5G
“The initial feedback is already positive. In sectors like renewable energy and construction, users highlight NB-IoT’s value in automating previously time-consuming processes,” he adds.
The technology’s future looks promising. Currently based on 4G standards, NB-IoT is designed for full 5G compatibility, ensuring a smooth transition without additional costs for users. This evolution will enhance technical parameters such as latency and bandwidth while preserving battery autonomy. Proximus NXT is also exploring emerging technologies like 5G Red Cap (Reduced Capacity), which could combine low energy consumption with higher data transmission rates—particularly useful for applications requiring increased bandwidth, such as advanced video surveillance or wearable devices.
