Brochure :: Test Challenges and Keysight Solutions for IoT Smart Devices.
The Internet of Things (IoT) has become increasingly prevalent in our daily lives. Examples include smart home appliances, home automation, entertainment systems, smart watches and wearable healthcare devices, as well as wireless sensor nodes within smart grid systems and smart cities.
Designers and manufacturers face unique challenges when testing IoT smart devices. For devices such as smart watches and fitness monitors, the designs must be small, cost-effective, and low-power in order to enhance wearability and extend battery life. Designers may find it necessary to use dense, highly-integrated circuits and SoC (systems on chip) devices. Due to capacitive and inductive coupling, the close proximity of power and signal paths may cause signal interference and crosstalk issues. 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 and systems. Whether you are integrating a new wireless module into your device, testing a new low-power module, or troubleshooting your designs, Keysight Technologies has solutions to these IoT design challenges to help you accelerate development and enable faster time-to-market.
Maximizing battery life for IoT smart devices.
The biggest challenge for IoT smart devices is the life of their small, on-board batteries. These devices, including smart home appliances and industrial sensor-nodes, must work for long periods of time between charges. Wearable medical devices, such as pacemakers and in-ear hearing aids, must not fail. Wireless sensor networks, which are widely deployed for industrial manufacturing process control, machine condition monitoring or the environmental monitoring of air, water and pollutants, may be located at rotating, remote or inaccessible locations, making replacement costs higher. Therefore, it is essential to understand these devices' power consumption patterns and battery life.
To maximize battery life, many devices are only active at brief intervals to send or receive data, and remain in standby or sleep mode otherwise. The device draws up to hundreds of milliamperes while in active mode, but will draw only microamperes while in sleep mode. High current spikes and transient effects also occur when the device is turned on and off frequently. This means that the equipment used to test these devices must accurately measure over a wide dynamic range, and perform fast measurements continuously to capture these single shot and transient current waveforms........
