India’s AMI Goals Met with RF Mesh Technology from Wirepas and Silicon Labs
| 
Wirepas provides scalable, reliable, and cost-efficient IoT connectivity solutions through its unique decentralized RF mesh network technology, empowering businesses to deploy and manage massive IoT networks with ease. Although the company was already well-established in smart metering, it expanded its presence into India in 2019, at a time when the smart metering market was still in its early phases. With Indian regulators fostering an open, technology-agnostic environment, Wirepas adopted a Make in India model. This approach enabled Indian manufacturers to license Wirepas technology, resulting in localized innovation. Supporting these deployments were integration services tailored specifically for India’s DLMS (Device Language Message Specification)-based systems, ensuring compliance with IS15959 standards.
Why RF Mesh?
Connectivity is crucial for the efficient operation of AMI in order to ensure frequent data collection, typically every 15 minutes, to monitor energy usage accurately. This connectivity helps utilities reduce technical and commercial losses by enabling accurate billing and reliable auditing, while also supporting the deployment and management of robust pre-payment meters. Anomalies can be remotely detected through tamper alerts and load profile analytics. Failure to transmit data to the head-end system within the specified 15-minute intervals can negatively affect SLA performance. Designed for a lifespan of over a decade with minimal human intervention, smart meters rely on dependable remote monitoring and management solutions. The choice of connectivity technology plays a critical role, significantly impacting long-term performance and operational costs.
RF mesh protocols have long been favored globally within utility networks due to their scalability and resilience. Unlike traditional mesh architectures that depend on standalone gateways or Data Concentrator Units (DCUs), Wirepas has introduced dynamic in-meter gateways, which are installed like standard meters at selected locations. This addresses the challenges associated with standalone gateways, such as cost, installation complexity, maintenance, and reliability. It offers all the perceived installation advantages of cellular-based setups while overcoming drawbacks like coverage blind spots and airtime costs. Additionally, wireless communication through RF mesh minimizes dead zones, ensuring consistent data flow and tamper detection critical to SLA adherence.
課題
India is currently advancing its Advanced Metering Infrastructure (AMI) initiative, aiming to replace 250 million electricity meters with smart meters nationwide. This ambitious project promises to significantly enhance energy efficiency and grid management. However, it faces several challenges, including unreliable connectivity, the high costs of cellular systems, difficulties in reaching remote areas, and stringent Service Level Agreement (SLA) requirements. Overcoming these obstacles is crucial for the successful implementation and operation of smart meters across the country.
ソリューション
Wirepas harnessed its advanced RF mesh technology to provide India with robust, efficient, and reliable AMI connectivity. By partnering closely with Silicon Labs, Wirepas integrated their self-healing, decentralized networks with Silicon Labs' EFR32FG23 wireless SoC.This combination of innovative software and hardware ensured wide-area coverage, high performance, and optimal cost efficiency.
その結果
A new smart meter connects to the Wirepas network every 8 seconds, and the collaborative RF mesh solution has already connected more than 5 million smart meters across India. This partnership is bringing cost-effective, reliable smart metering to India and helping utilities reduce installation complexities and operational expenses while meeting a remarkable 99% SLA compliance rate.
India’s AMI Program – Progress from Regulatory Reforms
India’s AMI program is one of the largest in the world and a key component of the Revamped Distribution Sector Scheme (RDSS), which was created specifically to address the financial and operational challenges faced by power distribution companies (discoms). India’s smart metering success can largely be attributed to these proactive government policies. This framework enabled structured implementation by offering performance-based funding mechanisms. It also standardized the use of technologies like RF and cellular, fostering innovation and competition. Private sector participation was encouraged, paving the way for collaborations like Wirepas and Silicon Labs.
An RF Mesh Platform that Meets India’s AMI Goals
Silicon Labs’ FG23 Sub-GHz SoC plays a pivotal role in addressing the technical requirements of India’s AMI program. With features like a 20 dBm power amplifier and high receiver sensitivity enabling kilometer-long communication coverage and low RAM/Flash usage aligning with Wirepas’ lightweight stack, it ensures performance without unnecessary costs. Coupled with Wirepas’ decentralized networks, the system dynamically adjusts to outdoor environments and overcomes RF challenges, scaling efficiently with each new meter deployment.
Silicon Labs’ low-power, long-range sub-GHz radio helped enhance signal reach while minimizing energy consumption. Together, Wirepas and Silicon Labs delivered an RF mesh platform tailored to India's AMI goals. Additionally, Silicon Labs' transparent roadmap and feedback-driven development process were instrumental for large-scale implementation.
The partnership between Wirepas and Silicon Labs demonstrates innovation at scale. By reducing communication costs via shared connectivity within RF mesh clusters, utilities have minimized their total cost of ownership. For instance, using the innovative in-meter gateway, a dual radio NIC (Network Interface Card) expands the reach of a single cellular connection to up to 300 smart meters via Wirepas RF mesh technology, drastically lowering subscription expenses. Users also benefit from instantaneous prepaid top-ups, showcasing reliability essential for consumer satisfaction.
Currently, India is deploying around 1-2 million meters per month, with an expectation to reach 40 million installed units by 2025. Wirepas’ flexible, firmware-upgradable designs ensure seamless enhancement of existing deployments, removing the need for costly overhauls. With advanced tools and end-to-end support courtesy of both Wirepas and Silicon Labs, utilities can focus on achieving their long-term goals.
Driving Success with Collaboration
Together, Wirepas and Silicon Labs exemplify how technology partnerships can address large-scale, complex challenges in rapidly developing regions. By coupling cutting-edge wireless technology with localized solutions, they are transforming India’s energy infrastructure, ensuring accountability, efficiency, and sustainability in power distribution for years to come.
