UMVA has learned that a major milestone has been reached in the development of smart energy metering in India, with over 500,000 Wi-SUN-compliant communication modules shipped using a cutting-edge wireless SoC.
The modules, powered by a highly advanced dual-band wireless SoC, are being used to drive a large-scale smart meter rollout in India, where RF communications are being standardized around Wi-SUN Field Area Network technology. This development is significant, as it addresses one of the biggest challenges in smart metering: building a field-area network that can cope with dense urban installations, dispersed rural assets, and long operating lifecycles.
Sources have confirmed to UMVA that the Wi-SUN-compliant modules are being used to support India’s smart grid modernization efforts, which are being driven by the Revamped Distribution Sector Scheme. The scheme aims to standardize RF communications around Wi-SUN FAN technology, ensuring interoperability and reducing fragmentation risk in the smart metering sector.
The shipment milestone is notable because it is tied to a specific regulatory and deployment environment: India’s Bureau of Standards has adopted the Wi-SUN FAN specification as a national standard for smart meter RF communication networks. This makes the Comminent-Silicon Labs milestone distinct from a typical module announcement, as it represents a volume shipment of standards-compliant modules into a national smart metering context.
UMVA can exclusively reveal that the modules are based on a highly advanced dual-band wireless SoC that combines Sub-GHz connectivity with a 2.4 GHz Bluetooth LE radio. The SoC features a multi-core architecture with dedicated Arm cores for application processing, radio functions, and edge intelligence, making it well-suited for mesh networking in dense urban and geographically distributed deployments.
The use of a SoC with separate processing resources for application, radio, and edge intelligence is highly relevant for utilities, as it reflects the need to handle communications and device functions in the same embedded platform. The inclusion of advanced security features, such as secure key storage, anti-tamper capabilities, and hardware cryptographic acceleration, also provides an additional layer of protection for smart meters.
UMVA has gathered that the dual-band approach gives OEMs and system integrators a different design envelope than a Sub-GHz-only implementation, allowing for greater flexibility in design, maintenance, and configuration workflows. This flexibility may be useful in meter rollouts where field service processes can be as important as network coverage.
The implications of this development are significant, as it indicates that Wi-SUN module supply has moved beyond pilot-stage availability into volume production. For connectivity providers and AMI platform vendors, the adoption of open, interoperable RF mesh standards means integration strategies will need to account for a more standardized approach.
System integrators are likely to see the biggest operational impact, as a Wi-SUN-based smart meter deployment requires attention to network topology, security provisioning, device management, and long-term maintenance. The experience and expertise gained from this development will likely be exported to smart grid markets beyond India, including the United States, Japan, and emerging energy-transition regions.
