3GPP has developed several standards to address the Internet of Things market in Release 13, including eMTC, NB-IoT, and EC-GSM-IoT. eMTC provides LTE enhancements for machine type communications with over 155dB coverage. NB-IoT is optimized for low-cost devices with up to 164dB coverage and supports three operation modes. EC-GSM-IoT enhances GSM with over 154dB coverage and security improvements. All three standards aim to support 10-year battery life, low device cost, and massive connectivity through various PHY layer optimizations and power saving features.
