Summary

The basic function of an IoT node is to collect data and send it through a wireless channel to the cloud. Since the power consumption of an IoT node is largely dominated by the wireless communication, it is therefore key to understand the trade-offs faced when designing the radio.

Content

• Introduction to the IoT.

• Brief description of the IoT wireless standards.

• General architecture of an IoT node.

• IoT radio architectures.

• Building blocks analysis and optimization in terms of power consumption, including LNA, mixer, oscillator, frequency synthesis, PA, baseband.

• Examples of a simple BTLE radio.

Keywords

IoT, IoT node, low-power, wireless communication, radios
