Silicon Labs, in a collaboration with IoT network provider Comminent, has surpassed 500,000 Wi-SUN-compliant module shipments for India’s smart grid infrastructure.
The modules for the smart grid are powered by Silicon Labs’ EFR32FG28 wireless system-on-chip (SoC) as part of the Bureau of Indian Standards (BS) adoption of the Wi-SUN field area network (FAN) specification (IEEE 2857-2021 and ISO/IEC/IECC 32857:2026) as the national standard for smart meter RF communication networks.
The Wi-SUN Alliance’s FAN 1.1 Low Energy certification, released in February 2026, opens the door for battery-powered and energy-harvesting nodes to join the same secure network and the higher-power infrastructure devices. Allowing thousands of new energy harvesting devices to be deployed at scale by utilities and cities without needing frequent manual maintenance or a separate infrastructure.
This includes:
- Smart parking meters
- Methane detection
- Fault monitoring
- Leakage detection
- Water and gas meters
- Smart agriculture, like soil moisture meters
- Rural deployments
“India’s smart metering rollout is one of the largest infrastructure transformations, and this milestone reflects the growing shift toward scalable, utility-grade communication networks like Wi-SUN,” said Amarjeet Kumar, founder and CEO of Comminent.
Comminent’s communication module using the Silicon Labs’ wireless SoC allows for large-scale smart grid and industrial IoT applications for long-range connectivity in hard field environments, the companies said.
The module features:
- Optimized dual-band connectivity
- Multi-core dedicated Arm cores
- Long-range sub-GHz radio
- 2.4 GHz Bluetooth Low Energy radio
- Silicon Labs’ Secure Vault technology
