NB IOT / CAT.NB1
Narrowband IoT (NB IoT) / Cat.NB1 was released by 3GPP (Release Version 13) as the new IoT narrowband communication in the LTE-Network and is the response of telecommunication companies to LoRa and SigFox. NB-IoT uses licensed frequency bands and the existing network infrastructure of the telecommunication provider.
NB IoT has a system dynamic that is 20 dB higher. This allows high building penetration down to basements. Due to the low energy consumption, the large ranges and low operating costs, the technology is suitable e.g. for smart meter applications.
