SmartMesh data reliability for IoT applications

The Industrial Internet of Things (IoT) requires industrial wireless sensor networks (WSNs) with stringent reliability and security.  Since such networks must operate reliably more than ten years without intervention, industrial WSNs must cope with severely changing environmental conditions over time. In addition, they must also be scalable and flexible so that the networks can support growing business needs and data traffic over a significant period of time.

SmartMesh^® wireless mesh network products from Linear Technology are engineered and vigorously tested for Industrial IoT applications, delivering >99.999% data reliability in some of the harshest environments. Prior to
each new SmartMesh software production release, Linear Technology accumulates over a million node-hours of network operation with a minimum of five nines (>99.999% data reliability) before it is declared production quality. 

This paper focuses on the methods Linear Technology uses to verify data reliability through radio hardware qualification, automated network test methodology, and systematic network testing. Performance statistics from a live production network are also reviewed.
