Cloud platform on the network
As a kind of narrowband Iot technology, NB-iot stands out in various industries, and its application covers many fields. This article will explain the main application categories and related features of NB-iot. What is NB-iot? Nb-iot refers to the Narrow band-Internet of Things technology. Nb-iot focuses on the low power wide coverage (LPWA) Internet of Things (IOT) market and is an emerging technology that can be widely applied worldwide. The NB-iot uses the licensed frequency band and can be deployed in in-band, protected band, or independent carrier to coexist with the existing network. Two, the NB-iot features four strong links: Under the same base station, the NB-iot can provide 50-100 times more access than existing wireless technology. One sector can support 100,000 connections, supporting low latency sensitivity, ultra-low device cost, low device power consumption and optimized network architecture. For example, due to limited bandwidth, operators only open 8-16 access points for each router in a family. However, there are often multiple mobile phones, laptops and tablets in a family. In the future, it will be a thorny problem to realize whole-house intelligence and hundreds of sensor devices need to be connected. The NB-iot can easily meet the networked needs of a large number of devices in the smart home of the future. High coverage: Strong indoor coverage capability of NB-iot, 20dB gain higher than LTE, equivalent to 100 times increased coverage capacity. It can not only meet the needs of wide coverage in rural areas, but also apply to the applications requiring deep coverage in factory areas, underground garages and manhole covers. Taking manhole cover monitoring as an example, GPRS in the past requires an antenna to be extended, which makes vehicle traffic easily damaged. However, AS long as NB-iot is properly deployed, it can solve this problem well. Low power consumption, low power consumption characteristics is an important index iot application, especially for some often can’t change the battery equipment and occasions, such as resettlement mountain wilderness in the remote areas of sensor monitoring equipment, they can’t like smart phone recharge from day to day, years of battery life is the most essential requirements. The NB-iot focuses on small data volume and small speed applications, so the power consumption of NB-iot devices can be very small, and the battery life of devices can be significantly increased from the past few months to several years. Low cost: Compared to LoRa, NB-iot does not require a network rebuild, and rf and antenna are essentially multiplexed. Take China Mobile as an example, there is a relatively wide frequency band in 900MHZ. Only part of 2G frequency band needs to be cleared, and LTE and NB-iot can be directly deployed at the same time. Low rate, low power consumption, and low bandwidth also bring low-cost advantages to NB-iot chips and modules. Modules are expected to cost less than $5. In the field of low-speed Internet of Things, NB-iot, as a new standard, achieves the extreme in cost, coverage, power consumption, connection number and other technologies. The technology is widely used in eight typical industries, including public utilities, healthcare, smart cities, consumers, agricultural environment, logistics and warehousing, intelligent buildings and manufacturing. Public utilities: meter reading (water/gas/electricity/heat), intelligent water (pipe network/leakage/quality inspection), intelligent fire extinguisher/fire hydrant. Medical care: drug traceability, telemedicine monitoring, blood pressure table, blood glucose meter, heart armor monitoring. Smart city: smart street lighting, smart parking, urban trash can management, public safety/alarm, construction site/urban water level monitoring. Consumers: wearable devices, bicycle/moped anti-theft, smart luggage, VIP tracking (kids/seniors/pets/vehicle rental), payment /POS. 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 & warehousing: asset/container tracking, warehouse management, fleet management/tracking, cold chain logistics (status/tracking). Intelligent building: 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 (appliances, machinery, etc.). As an emerging Internet of Things technology, NB-iot has attracted much attention due to its features such as 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.
