Low-rate services: The industry has summarized the low-rate service market into the LPWAN (Low Power Wide Area Network) market, which is a low-power wide area network. Currently, there is no corresponding cellular technology. In most cases, it is supported by GPRS technology, which brings with it high costs and low rates of low-speed services.


In other words, the current low-rate business market is in urgent need of development, and the low-rate business market is actually the largest market, such as fire extinguishers in buildings and various monitors used in scientific research. The frequency of such equipment in life is very low. However, the total number of collections is very impressive. The collection of these data is used for various purposes, such as improving the configuration of urban equipment.


The NB-IoT is a new narrowband cellular communication LPWAN (Low Power Wide Area Network) technology that can help us solve this problem.


Second, what are the advantages of NB-IoT?


As a technology applied to low-rate services, the advantages of NB-IoT are not hard to imagine:

Strong links: In the same base station scenario, NB-IoT can provide 50-100 times more access than existing wireless technologies. 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 the limited bandwidth, operators only open 8-16 access ports for each router in the home. In a home, there are often multiple mobile phones, laptops, and tablet computers. The need for networking of hundreds of sensing devices has become a thorny problem. The NB-IoT is enough to easily meet the networking needs of a large number of devices in future smart homes.


High coverage: The indoor coverage of NB-IoT is strong, and its gain is 20dB higher than that of LTE, which is equivalent to 100 times more coverage area. Not only can it meet the demand for a wide coverage in rural areas, but it also applies to applications such as plant sites, underground garages, and well covers that require deep coverage. Take manhole cover monitoring as an example. In the past, the GPRS method needed to extend an antenna, which could easily cause damage to vehicles. However, as long as NB-IoT is properly deployed, it can solve this problem.
