Smart meters of millions of households need replacement

Most household smart meters need updating as they currently rely on a GPRS connection via the 2G network. This technology allows network operators to receive meter readings and provides consumers insights into their consumption. However, Dutch operators such as KPN, Vodafone, and Odido are decommissioning the obsolete 2G and 3G technologies in a process called ‘sunset’, scheduled for completion by 2025.

The discontinuation of 2G and 3G networks will significantly impact network operations. Once these networks are retired, smart meters using GPRS connections will be unable to transmit meter readings. This phase-out began with Softbank in Japan discontinuing its 2G network in 2011, followed by similar actions in Sweden and Australia in 2016. Since 2017, the phase-out pace has accelerated, with over 70 planned discontinuations for the 2G network and more than 80 for the 3G network globally. Consequently, millions of meters worldwide will need to be replaced by the end of 2030 to maintain functionality.

No Data Without Smart Meters

Smart meters do more than just log meter readings; they also monitor grid voltages. This capability is crucial when voltage issues or outages occur, as the data can be accessed remotely to address specific problems in affected areas promptly. As we move towards integrating more sustainable energy sources, understanding these data fluctuations—increased peaks and troughs in energy supply—becomes even more essential. Most gas meters relay their readings through smart electricity meters. However, the first-generation gas meters are not compatible with newer smart electricity meters, necessitating the replacement of millions of these units to ensure seamless communication.

Until When Will the 4G Network Remain Active?

The latest meters are being outfitted with 4G (LTE), LTE-M, and NB-IOT technologies. Launched in 2008 by the 3rd Generation Partnership Project (3GPP), 4G networks are foundational for current mobile communications and are projected to remain active for at least another decade. This longevity ensures continued support before a gradual phase-out to accommodate advancements like 6G. Learn more about the transition from 4G to 5G here.

What is the LTE-M Network?

LTE-M, or Long Term Evolution for Machines, caters specifically to Internet of Things (IoT) applications. Based on the secure and reliable 4G standard developed by the GSMA’s 3GPP, LTE-M facilitates international roaming and offers significant coverage enhancements, particularly in buildings. Its advantages include quick, energy-efficient data transmission, making it ideal for upgrading current 2G applications and enabling new ‘smart’ functionalities.

What is NB-IOT?

NB-IOT (NarrowBand Internet of Things) leverages the GSMA’s 5G standards and is compatible with both 4G and 5G networks. Like LTE-M, NB-IOT offers extensive indoor coverage and energy efficiency, extending device longevity. It differs primarily in its use; while LTE-M supports long-distance and mobile connectivity (e.g., GPS systems), NB-IOT is better suited for stationary devices, such as environmental sensors.

The Solution: A Modular Meter

As network technologies evolve, both benefits and challenges arise. One significant challenge is the need to replace devices that only support outdated technologies. To address this, developers are creating modular meters with replaceable communication modules, which can be easily swapped out as needed, significantly extending the meter’s usable life and reducing waste.
