What is NB-IoT (narrowband Internet of Things)? What are the main applications of NB-IoT?


365betSecurity knowledge network

The Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and consumes only about 180KHz of bandwidth. It can be deployed directly on GSM networks, UMTS networks or LTE networks to reduce deployment costs and achieve smooth upgrades.

What is NB-IoT?

365betNB-IoT is an emerging technology in the IoT space that supports low-power devices in the WAN cellular data connection, 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. The battery life of the NB-IoT device is said to increase for at least 10 years while providing a very comprehensive indoor cellular data connection coverage.

For the development of the Internet of Things standards, Huawei's advancement was the earliest. In May 2014, Huawei proposed narrowband technology NB M2M; in May 2015, NB OFDMA was formed to form NB-CIOT; in July, NB-LTE and NB-CIOT were further integrated to form NB-IOT; NB-IOT standard is expected to be 3GPP R13 appeared and was frozen in June 2016.

365betPreviously, compared with NB-LTE promoted by Ericsson, Nokia and Intel, 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 equipment. The upstream and downstream of the system industry chain have joined the camp.

365betFocusing on the low-power wide coverage (LPWA) Internet of Things (IoT) market, NB-IOT is an emerging technology that can be used globally. It has the characteristics of wide coverage, many connections, fast speed, low cost, low power consumption and excellent architecture. The NB-IOT uses the license band and can adopt three deployment modes: in-band, guard band, or independent carrier to coexist with the existing network.

Main application classification of NB-IoT

In the low-speed Internet of Things, NB-IoT is a new system that achieves the ultimate in cost, coverage, power consumption, and connection count. The technology is widely used in eight typical industries such as public utilities, medical health, smart cities, consumers, agricultural environments, logistics and warehousing, intelligent buildings, and manufacturing industries.

Utilities: meter reading (water/gas/electricity/heat), smart water (pipe network/leakage/quality inspection), intelligent fire extinguisher/hydraulic hydrant.

365betMedical health: drug traceability, telemedicine monitoring, blood pressure meter, blood glucose meter, and armor monitoring.

Smart City: Smart Street Lights, Smart Parking, Urban Trash Management, Public Safety/Alarms, Construction Site/Urban Water Level Monitoring.

365betConsumers: wearables, bicycle/assisted car theft, smart luggage, VIP tracking (child/elder/pet/vehicle rental), payment/POS machine.

365betAgricultural 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) .

365betLogistics warehousing: asset/container tracking, warehousing management, fleet management/tracking, cold chain logistics (status/tracking).

Intelligent buildings: access control, intelligent HVAC, smoke/fire detection, elevator failure/maintenance.

Manufacturing industry: production / equipment status monitoring, energy facilities / oil and gas monitoring, chemical park monitoring, large rental equipment, predictive maintenance (home appliances, machinery, etc.).

NB-IoT is an emerging IoT technology. Because of its low power consumption, stable connection, low cost, and excellent architecture optimization, NB-IoT has attracted much attention. As NB-IoT technology becomes more and more mature, it will appear in more fields. .
