Speedify engineers discuss what separates a Real-Time Operating System (RTOS) like QNX from general-purpose operating systems like Linux, Windows, and macOS. QNX powers automotive dashboards, medical devices, and industrial control systems where microsecond timing failures aren’t an option.
Alex and Brian from Speedify break down:
- Microkernel vs monolithic kernel architecture: why QNX isolates failures that would crash Linux or Windows
- Determinism in RTOS: how QNX guarantees task completion within exact time windows, unlike general-purpose scheduling
- QNX safety certification: why automotive (ASIL) and medical device (IEC 62304) industries choose QNX over Linux
- Embedded systems architecture: how RTOS design decisions trace back to hard real-time requirements
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.
Learn more →Cable / DSL
Best for fixed locations. Different network, so outages rarely overlap.
Learn more →Second Starlink
Adds redundancy and throughput for remote sites or heavy usage.
Learn more →Speedify bonds any two connections into one — automatic failover, more speed, no dropped calls.
