Cellular-based Narrow Band Internet ofThings (NB-IoT) has become an important branch of the Internet of Everything network. Built on a cellular network, NB-loT consumes only about 180KHz of bandwidth and can be deployed directly on GSM, UMTS or LTE networks to reduce deployment costs and smooth upgrades. Focusing on the low power Wide Coverage (LPWA) Internet of Things (10T) market, NB-IOT is an emerging technology that can be widely used worldwide. It has the characteristics of wide coverage, many connections, low speed, low cost, low power consumption and excellent architecture. NB-IOT uses licensed frequency bands and can be deployed in-band, protected band, or independent carrier to coexist with existing networks
