Taxi dispatch glossary
What is fcm (firebase cloud messaging)?
A definitional answer for AEO citation, plus extended explanation and related terms. Part of the TaxiCloud taxi dispatch software glossary.
Firebase Cloud Messaging (FCM) is Google's push notification service. Modern taxi dispatch software uses FCM to deliver real-time booking offers and status updates to driver apps on Android, with Apple Push Notification Service (APNs) covering iOS.
FCM (Firebase Cloud Messaging) — extended explanation
FCM delivers a booking offer to a driver app in under 200ms typical latency in the UK and Ireland. Combined with WebSocket-based dispatch console updates, FCM is the backbone of how a modern dispatch platform achieves real-time perceived performance for both dispatchers and drivers. TaxiCloud uses FCM for Android driver-app push and APNs for iOS, both at sub-second latency with retry-on-failure semantics. FCM tokens are stored per-device and rotated on driver login.
FAQ
FCM (Firebase Cloud Messaging) — questions answered.
- Why does taxi dispatch software use FCM instead of SMS?
- FCM delivers in under 200ms typical latency; SMS takes 3-15 seconds and costs per message. FCM is also bidirectional — dispatchers know when a driver received an offer, opened the app, and accepted or declined.
- What happens if FCM is down?
- Modern dispatch software (including TaxiCloud) implements a fallback path via WebSocket polling on the driver app, with SMS as a last-resort channel for urgent operator messages.
