From Polling to Streaming: The Telemetry Revolution

Traditional REST API polling is too slow and inefficient for modern vehicle applications. A real-time, push-based streaming architecture is essential for building responsive and data-rich experiences.

API Polling Inefficiency
Constantly polling for updates creates high server load, wastes bandwidth, and often delivers stale data, making it unsuitable for real-time needs.
High Data Latency
The delay between a vehicle event and its availability via a polled API makes it impossible to build applications that require instant feedback.
Scalability Limits
Polling thousands or millions of vehicles creates a massive, unsustainable strain on backend infrastructure, leading to high costs and poor performance.

The Solution: A Real-time MQTT Stream for Developers

EMQX provides a persistent, secure MQTT connection to each vehicle, pushing data to your applications the moment it's generated.

The Solution: A for Developers
Secure Vehicle Connection
Vehicles establish a secure, persistent MQTT session, authenticated via TLS and device certificates.
Subscribe to Data Streams
Your applications subscribe to specific MQTT topics to receive the telemetry data they need in real time.
Push to Developer Endpoints
EMQX instantly pushes data to your subscribed clients, databases, or cloud services as it arrives from the vehicle.
