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 directly deployed on GSM, UMTS or LTE networks to reduce deployment costs and achieve smooth upgrades.
What is NB-IoT
Nb-iot is an emerging technology in the field of IoT, which supports cellular data connection of low-power devices in wan, also known as low-power wide area network (LPWAN). Nb-iot supports efficient connection of devices with long standby time and high network connection requirements. Nb-iot devices are said to provide at least 10 years of increased battery life while providing very comprehensive coverage of indoor cellular data connections.
Huawei is the earliest to promote the development of iot standards. In May 2014, huawei proposed narrow-band technology. In May 2015, NB OFDMA was fused to form nb-ciot. In July, nb-lte further merged with nb-ciot to form nb-iot. It is expected that the nb-iot standard will appear in 3GPP R13 and be frozen in June 2016.
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, chip vendors and the upstream and downstream of the equipment system industry chain, than Ericsson, nokia and Intel's nb-lte.
Nb-iot focuses on the low power wide coverage (LPWA) Internet of things (IOT) market, which is an emerging technology that can be widely applied in the global scope. It is characterized by 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.
Major application categories of NB-IoT
In the field of low-speed Internet of things, nb-iot, as a new system, achieves perfection in cost, coverage, power consumption, connection number and other technologies. The technology has been widely used in eight typical industries such as public utilities, medical care and health, smart city, consumers, agricultural environment, logistics and warehousing, intelligent buildings and manufacturing.
Utilities: meter reading (water/gas/electricity/heat), intelligent water (pipe network/leakage/quality inspection), intelligent fire extinguisher/hydrant.
Medical health: drug traceability, telemedicine monitoring, blood pressure meter, glucose meter, heart armor monitoring.
Smart city: intelligent street lamp, intelligent parking, urban garbage can management, public safety/alarm, construction site/urban water level monitoring.
Consumers: wearable devices, bicycle/scooter anti-theft, intelligent luggage, VIP tracking (children/the elderly/pets/car rental), payment /POS machine.
Agricultural environment: precision planting (environmental parameters: water/temperature/light/medicine/fertilizer), animal husbandry (health/tracking), aquaculture, food safety traceability, urban environmental monitoring (water pollution/noise/air quality PM2.5).
Logistics and warehousing: asset/container tracking, warehousing management, fleet management/tracking, cold chain logistics (status/tracking).
Intelligent buildings: access control, intelligent HVAC, smoke/fire detection, elevator fault/maintenance.
Manufacturing industry: production/equipment status monitoring, energy facilities/oil and gas monitoring, chemical park monitoring, large-scale leasing equipment, predictive maintenance (home appliances, machinery, etc.).
Nb-iot is an emerging Internet of things technology, which has attracted much attention due to its features of low power consumption, stable connection, low cost and excellent architecture optimization. As nb-iot technology becomes more and more mature, it will appear in more fields.
