Narrowband Internet of Things (NB-IoT) has been introduced to provide inexpensive, low-power, and broad cellular connectivity for the Internet of Things. This system, based on Long Term Evolution (LTE) technology, supports most LTE functions even though with simplification it is important to reduce the complexity of the device. The new NB-IoT developed by 3GPP in the last 2 years, the application developed is smart metering, smart building, smart parking and bicycle sharing. The first operational pilot project using intelligent electric energy meters and NB-IoT communication technology has begun at Parque das Nações in Lisbon. Vodafone h
