The nb-iot card Narrow Band Internet of Things (nb-iot) has become an important branch of the Internet of everything.Nb-iot is built on cellular networks and consumes only about 180KHz of bandwidth. It can be deployed directly on GSM, UMTS, or LTE networks to reduce deployment costs and achieve smooth upgrades.Nb-iot is an emerging technology in the field of IoT that supports cellular data connectivity of low-power devices over wide area networks (wans), also known as low power wide area networks (lpwans).Nb-iot supports efficient connectivity for devices with long standby times and high network connectivity requirements.Nb-iot devices are said to be able to increase their battery life to at least 10 years while also providing very comprehensive coverage of indoor cellular data connections.
Previously, huawei paid more attention to the construction of nb-ciot ecosystem, including qualcomm, vodafone, deutsche telekom, China mobile, China unicom, Bell and other mainstream operators, chipmakers and the upstream and downstream of the equipment system industry chain, compared with the nb-lte driven by Ericsson, nokia and Intel.Nb-iot focuses on the low power wide coverage (LPWA) Internet of things (IoT) market and is an emerging technology that can be widely used on a global scale.It has the characteristics of wide coverage, multiple connections, fast speed, low cost, low power consumption and excellent architecture.Nb-iot USES License frequency band, which can be deployed in three ways, including in-band, protection band or independent carrier, to coexist with the existing network.
