Expanded Coverage-GSM-IoT is a low-power wide area (LPWA) cellular innovation. It is dependent on eGPRS and planned as a high capacity, low energy cellular system for IoT applications. This will take into account EC-GSM-IoT networks to co-exist with 2G, 3G, and 4G mobile networks. Extended Coverage GSM IoT was proposed as a feature of the 3GPP Release 13 specification. The EC-GSM-IoT has further developed security, contrasted with the current GSM/GPRS organizations, and offers trustworthiness assurance, shared verification and need for stronger ciphering algorithms.
