An IoT device will have a radio that can send and receive wireless communications. IoT wireless protocols are designed to accomplish some basic services: Operate on low power, use low bandwidth and work on a mesh network. Some work on the 2.4 GHz band, which is also used by Wi-Fi and Bluetooth, and the sub-GHz range. The sub-GHz frequencies, including 868 and 915 MHz bands, may have the advantage of less interference.
