Solving Test Challenges for Internet of Things-Enabled Devices
Application Notes
Introduction
The internet of things (IoT) affects many aspects of our lives, including home automation, entertainment systems, security and alarm systems, smart watches and wearable health monitors, smart traffic devices, waste management devices, and connected cars. IoT will touch almost every consumer and industrial application.
These IoT devices create unique challenges for designers and manufacturers. For devices such as smart watches and fitness monitors, the designs must be small, cost-effective, and low-power. Designers may find it necessary to use dense, highly-integrated circuits and SoC (systems on chip) devices, which because of the close proximity of power and signal paths may cause signal interference and crosstalk issues due to the capacitive and inductive coupling. New hardware must support multiple wireless platforms with low power consumption. Consumer electronic devices must also support multiple wireless formats to ensure interoperability between different vendors or systems.
