Smart Highways and Roads: 5G Wireless Solutions for public safety

CableFree Private 5G: Enabling Dedicated Networks for Emergency Services in Smart Highway and Road Projects

5G Smart Highways Introduction

In the era of smart infrastructure, highways and roads are evolving into connected ecosystems that prioritize safety, resilience, and rapid response. CableFree Private 5G networks provide a robust, dedicated wireless solution tailored for these environments, creating isolated, high-performance networks exclusively for emergency services and first responders. This application note explores how CableFree Private 5G supports smart highway projects by integrating real-time video communications and IoT sensor networks to detect and mitigate hazards such as earthquakes, floods, and landslides. By leveraging ultra-low latency, enhanced security, and scalable connectivity, these networks ensure seamless coordination during critical incidents, ultimately saving lives and minimizing disruptions.

Solution Overview

CableFree Private 5G deploys a fully managed, on-premises 5G core network that operates independently of public cellular infrastructure, offering complete control over bandwidth allocation and service prioritization. This dedicated network spans highway corridors, integrating with roadside units (RSUs), responder vehicles, and environmental sensors to form a resilient communication backbone.

Key components include:

• High-Capacity Base Stations: 5G sub-6 GHz radios for wide coverage along highways, using dedicated spectrum frequency bands
• Edge Computing Integration: On-site data processing for instantaneous analytics.
• Network Management System (NMS): A “single pane of glass” interface for monitoring and orchestration.

This setup enables real-time data exchange between first responder vehicles, command centers, and IoT devices, supporting mission-critical applications in dynamic road environments.

Key Features

CableFree Private 5G excels in integrating advanced capabilities for emergency response:

• Video Uplink/Downlink to Responder Vehicles: High-definition live streaming from body cams, dash cams, and drones to vehicles and control rooms, with sub-10ms latency for situational awareness. Supports 4K video feeds without bandwidth contention.
• IoT Sensor Networks for Disaster Detection: Deployment of thousands of low-power sensors along roadsides to monitor seismic activity (earthquakes), water levels (floods), soil stability (landslides), and structural integrity. Sensors transmit alerts via 5G RedCap and Massive IoT, triggering automated evacuations or traffic rerouting.
• Connect civilian drones for remote hazard assessment:
  Civilian drones can fly over affected areas and link video feeds to first responders with ease
• High Availability, No Congestion:
  Private Network doesn’t use resources of public cell networks which may be down or congested during emergency events such as natural disasters or other. Can be built to higher levels of resilience than commercial networks with redundant power and backhaul.

These features ensure proactive hazard mitigation, with seamless scalability for expanding smart highway projects.

Major Advantages

CableFree Private 5G delivers transformative benefits across core pillars of emergency operations on smart highways.

Safety

• Real-Time Hazard Detection and Response: IoT sensors provide instant alerts for natural disasters, allowing first responders to deploy resources preemptively. For instance, landslide detection can trigger dynamic traffic signaling to prevent accidents.
• Enhanced Situational Awareness: Video uplinks from vehicles enable commanders to assess scenes remotely, reducing responder exposure to risks like active incidents or environmental hazards. This results in faster, safer interventions, potentially reducing response times by up to 50%.

Automation

• AI-Driven Automation: Edge-integrated 5G enables automated workflows, such as drone swarms for flood mapping or AI-analyzed video for traffic optimization during emergencies.
• Seamless Vehicle-to-Infrastructure (V2I) Communication: Responder vehicles receive automated updates from sensors, enabling self-driving convoy formations or predictive maintenance alerts, streamlining operations without manual intervention.

Security

• End-to-End Encryption and Isolation: All data—from IoT sensors to video streams—is encrypted with 5G standards, with no exposure to public networks, eliminating interception risks in sensitive operations.
• On-Premises Control: Local 5G core prevents data leakage, ensuring compliance with public safety regulations and protecting against cyber threats targeting emergency communications.

Efficiency

• Low-Latency, High-Reliability Connectivity: Sub-millisecond latency supports uninterrupted video and sensor data flows, even in high-mobility scenarios like pursuing vehicles on highways.
• Resource Optimization: Prioritized QoS allocates bandwidth dynamically, reducing operational costs by minimizing downtime and enabling efficient spectrum use across vast road networks.
