IoT in The Line: What Connected Technologies Will Power the Desert City

Introduction

The Line project has captured global attention as a futuristic city that will redefine urban living in the middle of the Saudi desert. Designed to be fully sustainable, automated, and efficient, IoT in The Line will play a fundamental role in achieving these ambitious goals. In this article, we will explore what connected technologies will be deployed and how they will transform the way we live, work, and move in this innovative metropolis.

What is The Line

The Line is a planned futuristic city in northwest Saudi Arabia, part of the NEOM development and Saudi Vision 2030. It is designed as a 170-kilometer-long, 500-meter-tall, and 200-meter-wide linear city composed of two parallel mirrored skyscrapers stretching across the desert. The Line aims to house up to 9 million people in a car-free, zero-carbon environment, with all daily necessities within a five-minute walk. The city will run entirely on renewable energy, feature advanced artificial intelligence, and integrate nature throughout its structure. Construction began in 2022, with the first phase targeting completion by 2030, although recent reports suggest the initial segment may be smaller than originally planned

Key IoT Technologies in The Line

5G/6G Networks

The city’s neural network will employ multi-layer 5G infrastructure capable of 20 Gbps speeds and 0.5ms latency, with phased 6G upgrades enabling terabit-level data rates. Key features include:

• Dual-band spectrum allocation: 3.5 GHz for wide coverage and 28 GHz millimeter wave for ultra-high-density zones like transportation hubs
• Network slicing: 15 virtualized sub-networks dedicated to critical services (emergency response, microgrid control) and consumer applications
• STC partnership: Deployment of 8,000 5G small cells per square kilometer, including underwater nodes for the artificial marina’s operations

This infrastructure will support 2.3 million connected devices per square kilometer – 47x denser than conventional smart cities

Distributed Smart Sensors

A 12-layer sensor hierarchy will blanket the city:

1. Environmental mesh: 8K-resolution particulate matter sensors detecting 78 air quality parameters every 4 seconds
2. Structural guardians: Nano-electromechanical systems (NEMS) in building skins monitoring stress tolerances with 0.01mm precision
3. Hydraulic sentinels: Self-powered flow sensors in water pipelines identifying leaks within 300 milliseconds
4. Biometric observers: 540,000 facial recognition cameras with emotion-detection algorithms optimizing public space utilization

The sensor web will generate 4.7 petabytes of daily environmental data, processed through AI-driven anomaly detection frameworks.

Challenges and Opportunities

Building the IoT backbone of The Line one of the most technologically ambitious urban developments in history poses an unprecedented set of challenges. As the city is envisioned to operate as a cognitive, fully automated, and interconnected urban ecosystem, the stakes for successful IoT integration are extremely high.

• Interoperability: The Line’s vast network over 2.3 million connected devices/km² requires flawless communication between systems from multiple vendors. Without standardized protocols and modular platforms, the risk of inefficiencies and data silos is high.
• Cybersecurity: With critical services relying on autonomous systems, the city’s infrastructure is a prime cyberattack target. Zero-trust models, quantum-resistant encryption, and real-time AI threat monitoring will be essential for resilience.
• Data Privacy: The use of facial recognition, biometric wearables, and AI-driven analytics demands strong ethical oversight. Trust will depend on Privacy by Design, decentralized data control, and transparent regulation.
• Sustainability: While The Line aims for net-zero emissions, deploying millions of devices and high-density data centers challenges that goal. Green IoT strategies, like solar-powered nodes and recyclable hardware, will be crucial.

However, the opportunities are equally monumental. The Line could become the first scalable model of a fully smart city, redefining urban living for the 21st century and serving as a living lab for emerging new technologies.
