# Industry News: ZTE and Partners Pilot Integrated 5G-A ISAC for Enhanced Airport Security
## Summary
ZTE, China Unicom Liaoning, and Dalian Changhai Airport have successfully launched a 5G-A private network integrating Intelligent Computing, Sensing, and Communication (ISAC) to significantly enhance low-altitude security and airport operations. This millimeter-wave based ISAC solution leverages edge AI to offer radar-like precision sensing capabilities within the communication infrastructure, dramatically improving the detection of "low, slow, small" aerial threats. The deployment offers major cost and space savings compared to traditional dual-system (communication plus radar) approaches, setting a new benchmark for critical infrastructure security.
## Key Details
- **Date:** Announced November 25, 2025 (Based on article date)
- **Companies Involved:** ZTE Corporation, China Unicom Liaoning, Dalian Changhai Airport
- **Category:** Product demonstration/Deployment, Technology validation
## The Story
The project focused on overcoming the security challenges faced by Dalian Changhai Airport, especially concerning drone and bird detection in complex maritime and island terrain. The solution utilizes ZTE's 5G-A millimeter-wave ISAC base stations, which use 5G signal reflections to precisely track targets (achieving sub-meter accuracy) without needing separate radar hardware. Edge computing running AI models fuses this sensing data with video and geo-location information for real-time threat classification. This integrated approach achieved a 98% detection accuracy, an 87% reduction in response time for runway intrusions (down to 2 minutes), and significantly reduced the blind spot rate for small aerial objects. Furthermore, the "one network, dual capabilities" architecture resulted in roughly 30% less deployment space and 25% lower capital expenditure compared to traditional setups.
## Business Impact
### For the Companies Involved
- **ZTE:** Validates the commercial viability and performance of its 5G-A ISAC technology, positioning them as leaders in integrated infrastructure solutions for private networks and critical sectors like aviation security and the emerging low-altitude economy.
- **China Unicom Liaoning:** Demonstrates leadership in deploying and managing advanced private 5G services for critical clients, enhancing their value proposition beyond traditional connectivity into managed high-value security solutions.
- **Dalian Changhai Airport:** Achieved immediate, measurable safety and efficiency gains, establishing a modern, cost-effective template for securing low-altitude airspace.
### For Competitors
- Competitors offering separate dedicated radar or sensor systems for perimeter security will face pressure to adopt converged, software-defined solutions like ISAC given the superior cost-effectiveness and streamlined deployment shown here.
- Telecom infrastructure vendors specializing purely in connectivity may see a diminishing value proposition unless they rapidly integrate advanced sensing and AI capabilities.
### For Customers
- **Airports, Ports, and Critical Infrastructure:** Gaining access to a proven, highly accurate, and more cost-efficient method of achieving comprehensive security monitoring, especially against modern threats like UAS (drones). This technology reduces operational burden (e.g., less reliance on manual patrols).
### For the Market
- This deployment strongly signalizes the shift from additive security layers to *embedded security and sensing* within next-generation communication networks (5G-A/6G). It legitimizes ISAC as a critical component for realizing the "low-altitude economy."
## Technical Implications
The core innovation lies in the efficient use of the **millimeter-wave spectrum** for both high-throughput communication and high-precision passive radar/sensing via signal reflection analysis. The integration of **edge AI** for real-time fusion and classification (e.g., bird vs. drone discrimination) is crucial for actionable intelligence. The use of **RedCap (Reduced Capability)** technology suggests scalability for numerous low-power sensors across the operational area.
## Strategic Analysis
- **Market Positioning:** ZTE and its partners have secured a first-mover advantage in demonstrating high-performance, unified sensing and communication for stringent government/infrastructure use cases in China.
- **Competitive Advantage:** The primary advantage is **resource efficiency** ("one network, dual capabilities") translating directly into lower CAPEX and reduced physical footprint, giving them a strong economic argument over legacy multi-vendor solutions.
- **Challenges:** Scaling this highly customized, millimeter-wave heavy solution across diverse airport environments (which may have different terrain or spectrum rules) will require standardized deployment models. Security validation for complex data fusion is also an ongoing challenge.
## Industry Reactions
- **Analyst Opinions:** Analysts are likely viewing this as external validation of the convergence trajectory predicted for 5G-Advanced/6G—where connectivity is merely the transport layer for sophisticated applications like sensing, positioning, and AI inference.
- **Expert Commentary:** Experts focusing on physical security integration will note the 87% response time reduction as a critical KPI, moving detection from minutes to seconds.
- **Market Response:** Expect increased interest from other sectors managing low-altitude airspace (e.g., ports, industrial campuses, border security) to replicate this solution.
## Future Outlook
- **Predictions and Expectations:** The partners plan to replicate this model in other regional airports and closed campuses, pushing refinement toward broader coverage and even higher precision fusion networks. This deployment is likely a precursor to broader commercial standardization of 5G-A ISAC base stations.
- **What to watch for:** Further case studies detailing transition costs from conventional systems, and announcements regarding open standards adoption for multi-vendor ISAC interoperability.
## For Security Professionals
Cybersecurity must be viewed broadly here: while the network is physically isolated (hard isolation, local core), providing **end-to-end security and data integrity** for passively sensed data that leads to autonomous response is paramount. Professionals need to ensure that the **edge desensitization** processes and robust lifecycle logging meet regulatory audit requirements, especially when relying on AI for critical threat classification.
