NB-IoT Solution

The connectivity grid of the future

NB-IoT system architecture

Narrow-Band IoT (NB-IoT) is a narrowband RF communication technology specially designed for the Internet of Things (IoT). It connects devices more simply and efficiently on already established mobile networks and handles small amounts of infrequent 2-way data, securely and reliably. The special focus of this standard is on very low power consumption, excellent penetration coverage and lower component costs, deployed in GSM and LTE regulated frequencies.


  • NB-IoT wireless communication.
  • No limit on the number of lamp controllers and transmission distance.
  • Supports three dimming modes: PWM, 0-10V, and DALI.
  • It uses a base station provided by the local network operator, no need to install gateways.
  • Remote real-time control and scheduled lighting by group or individual lamp.
  • The alarm on the lamp failure.
  • Pole tilt, GPS, and RTC options.
  • Application: Any place that can receive NB-IoT signal.

How NB-IoT lighting control system works

Think of an NB-IoT smart lighting control system as a smart, responsive computer network that gives light. In general, Yibai’s NB-IoT control system connected lighting system consists of three main levels or layers: hardware installed in the illuminated space, software accessible via the cloud, and optional services from our company.

LED Smart Lighting 6 (2)


The NB-IoT lighting control system uses both lighting hardware and networking hardware. In illuminated spaces, connected LED luminaires, while sensors of various kinds collect data from the illuminated environment. Behind the scenes, lighting controllers and standard networking devices afford connectivity and integration.


The cloud-based platform serves the full range of software applications for lighting management, monitoring, and control. Collected data is stored in the cloud, along with analysis and visualization tools for turning data into insight.

Supports from Yibai Company

Professional, managed, and lifecycle services from Yibai LED lighting offers such aids as system audit and design, remote system management and maintenance, UV-C disinfection, and light as a service, where you buy the light, not the lighting.
