The next part of an IoT device is the RF module. The use case for the IoT device will help determine if the RF module will need to be a long range solutions like cellular or satellite technologies or short range solutions like wireless, ZigBee or Bluetooth. As well, consideration will need to be given regarding the delivery of data from a short range technology like Bluetooth, to a data repository. For example, a wearable fitness tracker typically uses Bluetooth to transmit from the device to a phone. From there, the app on the phone is connected to a cloud-based data repository. Another example is of home-based security and automation solutions (like automated light bulbs, motion sensors and cameras). These devices will typically send data and the connectivity solutions will impact the power source choices for the device.
