Indian IoT infrastructure specialist Comminent and Silicon Labs have shipped more than 500,000 Wi-SUN-compliant communication modules for India’s national smart meter roll-out.

The modules are powered by Silicon Labs’ EFR32FG28 Wireless System-on-Chip (SoC) and are designed for large-scale mesh networking. The deployment is part of India’s Revamped Distribution Sector Scheme (RDSS), which aims to modernise the country’s power distribution infrastructure.

The Bureau of Indian Standards recently adopted the Wi-SUN Field Area Network specification as the national standard for smart meter RF communication. This standardisation is intended to ensure interoperability and security across different utility-grade IoT applications and smart city networks.

“India’s smart metering roll-out is one of the largest infrastructure transformations, and this milestone reflects the growing shift toward scalable, utility-grade communication networks,” said Amarjeet Kumar, Founder and CEO of Comminent.

The EFR32FG28 platform features dual-band connectivity and hardware-based security. Comminent stated that it is now looking to expand its Wi-SUN-based communication solutions into global markets, including the United States and Japan, as utilities transition toward real-time grid monitoring.
