Benefits

The ADEX framework has been explicitly designed to meet the core requirements for drone detect & avoid (DAA) systems, and airport flight information displays (FIDs). Unlike traditional centralised architectures, which concentrate data handling and routing within a small number of cloud or enterprise systems, ADEX distributes decision-making and data ownership across a framework of independently operated clients and servers. This structural difference allows it to better satisfy key operational objectives:

Comparison	Centralised Services	ADEX
Latency	Delays from network hops and cloud buffering, particularly in peak periods, can compromise latency.	Point-to-point architecture easily achieves sub-2 second latency, even during peak periods
Availability	Failure at the central hub causes loss of surveillance data across all dependent systems.	Independent server/client operation with local processing localises faults and maintains service continuity.
Scalability	Requires vertically integrated expansion, which can bottleneck growth.	Horizontally scalable through independent deployment of sensors, data servers, and display providers.
Openness	Closed interfaces limit integration and competitive innovation.	Standards-based interfaces enable plug-and-play interoperability across the surveillance ecosystem.
Agency	External domain data handling reduces control for local stakeholders.	Servers and clients can be locally hosted, giving full control over data governance and security.
Federation	Limited compatibility with federated or independent systems.	Supports discovery and coordination among independently managed systems.
Resilience	Central points of failure are vulnerable to cyber threats and outages.	Distributed architecture eliminates single points of failure and enables graceful degradation.
