Prototype smart meter gateway adopts PPC 5G RedCap solution
In a joint field trial, PPC integrated a 5G RedCap cellular module into a prototype smart meter gateway. The devices utilize Telefonica Deutschlands 700 MHz spectrum to forward energy consumption data directly to E.ON Grid Solutions backend. The demonstration generates operational insights and validates seamless interoperability among gateway hardware, mobile network infrastructure and backend systems under realistic conditions, confirming robust performance and readiness for scalable deployment within live grid environments.
700 MHz Enables High Range and Reliable Building Penetration
The 700 MHz band offers significant advantages for connectivity by combining lower spectral frequencies with enhanced propagation characteristics, resulting in extended coverage. Its reach is especially beneficial for smart utility deployments in challenging locations such as underground rooms or densely built urban environments. Reliable signal penetration through walls and foundations ensures consistent data transmission to smart meter gateways, enabling continuous energy measurement in environments that typically hinder higher-frequency wireless transmissions.
5G RedCap Reduces IoT Complexity and Cuts Power Consumption
The 5G standards Reduced Capability profile streamlines device architecture by eliminating unnecessary features tailored to high-bandwidth applications, lowering hardware complexity and energy demand. Despite its optimized design for moderate data throughput, RedCap retains sufficient performance overhead to ensure consistent transmission of measurement data without interruption. Moreover, it can dynamically accommodate supplementary Internet of Things services, seamlessly integrating additional sensors or telemetry functions while preserving battery life and minimizing network load.
5G RedCap delivers future-proof, scalable connectivity for smart meters
Reliable performance over extended periods is crucial for smart metering systems. 5G RedCap offers energy providers a forward-looking cellular connection with scalable economics, enabling operators to expand infrastructure cost-effectively as demand grows. By gradually migrating existing LTE networks to 5G, organizations can protect investments in equipment while exploring enhanced capabilities. This phased approach fosters operational flexibility and long-term security, supporting evolving communication requirements without compromising system stability or predictability.
Partners Evaluate Prototype Test Insights To Drive Broad Rollout
Upon completion of prototype tests, the partners will analyze network availability, installation site performance, and integration dynamics between gateways, cellular infrastructure, and backend systems. Insights derived from practical detailed coverage reports, comprehensive empirical installation assessments, and extensive interoperability tests will guide architectural refinements. These findings will feed into the next phase of product and solution development, ensuring the technology’s readiness, scalability, and robustness in preparation for a broad commercial rollout.
Deploying 5G RedCap in the 700 MHz band provides smart-meter operators with energy-efficient, cost-effective WAN link that maintains continuous data transmission. Its extended range and building penetration minimize signal loss in basements and dense urban environments. Simplified device architecture and low power consumption extend operational long-term lifespan and ease maintenance. RedCap facilitates seamless migration from existing LTE networks towards full 5G, ensuring scalable, futureproof connectivity for next generation smart-meter gateways.
