For many, the name Nokia evokes nostalgia and a reputation for resilient hardware. Today, the company is stepping into a new era by integrating blockchain technology into its vision for smart urban development.
At the upcoming Mobile World Congress, Nokia plans to showcase three innovative smart city solutions. These include an IoT Central Operations Platform, a blockchain-powered sensing-as-a-service (SaaS) system, and a specialized Mobile Virtual Network Operator (MVNO) solution designed for public safety applications.
Nokia’s Blockchain-Based Sensing-as-a-Service
One of the most significant announcements is Nokia’s sensing-as-a-service platform, which relies on blockchain technology. This system is designed to be compatible with existing cellular base stations, allowing operators to upgrade their infrastructure via software updates. By adding narrowband IoT capabilities, cities can deploy sensors across urban sites to collect and sell anonymous data.
A secure, efficient micro-payment system is essential for monetizing this data—and that’s where Nokia’s blockchain comes in. It ensures trust, transparency, and reliability in transactions between data providers and consumers.
The IoT Central Operations Platform
Beyond blockchain, Nokia is introducing a centralized smart city platform aimed at integrating and managing various urban operations. This system supports video surveillance, smart lighting, parking management, waste disposal, and environmental monitoring.
Phil Twist, Vice President of Marketing for Mobile Networks at Nokia, emphasized usability as a core goal: “We shouldn’t assume that city managers are telecom experts. Our platform simplifies the process by serving as a hub that works with existing vendor systems and supports a wide range of IoT applications.”
Enhancing Public Safety with Secure Networks
Another critical component of Nokia’s smart city initiative is focused on public safety. The company is proposing an MVNO model that allows operators to offer high-security broadband services to public safety agencies over commercial LTE networks.
This approach ensures that even personnel without technical network expertise can leverage LTE technology to improve operational efficiency and emergency response.
Why Blockchain Matters for Smart Cities
Asad Rizvi, Global Head of Business Development at Nokia, highlighted the role of digitalization in urban management: “Cities need to digitize to serve residents efficiently. This requires shared, secure, and scalable infrastructure—which is where our blockchain technology adds value.”
Blockchain can enhance data integrity, enable automated micropayments, and ensure that information shared across municipal departments is accurate and tamper-proof.
Moreover, Nokia’s integrated approach allows telecom operators to use their existing networks to generate new revenue streams by offering services to city administrations, transportation authorities, and public safety agencies.
How Nokia’s Approach Compares to Other Technologies
Nokia’s vision of a blockchain-enabled IoT ecosystem draws natural comparisons with other distributed ledger technologies like IOTA, which is also designed for machine-to-machine communication and microtransactions.
While IOTA uses a directed acyclic graph (DAG) structure instead of a conventional blockchain, both aim to create trustless, scalable networks for IoT devices. Nokia’s advantage may lie in its existing infrastructure partnerships and experience in telecommunications.

The Road Ahead for Blockchain and Smart Cities
Nokia’s re-entry into the tech spotlight with blockchain and IoT reflects a broader trend of traditional companies embracing decentralized technologies. Smart cities rely on interconnected systems, and blockchain offers a promising way to enhance security, transparency, and efficiency.
Whether it’s managing energy grids, optimizing traffic flow, or improving public services, the integration of blockchain with IoT could redefine how urban centers operate in the near future.
Frequently Asked Questions
What is sensing-as-a-service?
Sensing-as-a-service refers to a model where sensor data is collected and sold as a service. In Nokia’s case, this data is anonymized and monetized using a blockchain-based micro-payment system.
How does blockchain improve smart city infrastructure?
Blockchain enhances security, enables transparent transactions, and ensures data integrity. It allows cities to deploy IoT devices at scale while maintaining trust between stakeholders.
Can existing networks support Nokia’s blockchain solution?
Yes. Nokia’s system is designed to be compatible with current cellular infrastructure. Operators can perform software upgrades to implement narrowband IoT and blockchain functionalities.
What makes Nokia’s approach different from IOTA?
While both focus on IoT and microtransactions, Nokia leverages its existing telecom partnerships and infrastructure. IOTA uses a different underlying architecture known as Tangle.
Is public safety a priority in Nokia’s smart city model?
Absolutely. Nokia includes an MVNO solution specifically designed to provide secure, high-priority LTE services to public safety agencies.
How can cities benefit from blockchain-based IoT systems?
Cities can improve operational efficiency, create new revenue streams, enhance public safety, and offer better services to residents through automated and secure data systems.
