NB-IoT is a brand-new narrowband IoT technology based on the cellular network, focusing on a low-power wide-area network, operating based on a licensed spectrum, and can be directly deployed on an LTE network, with low deployment cost and smooth upgrade capability.
Based on the Internet of Things environment, the data transmission of shared bicycles through the GPRS network is relatively common, and the development of low-power wide-area networks has further promoted the elimination of GPRS in the market.
With the rapid growth of the number of shared bicycles, the number of bicycles parked in the same place is also increasing, but the success rate of successfully opening a certain car is also getting lower and lower. GPS-модуль
At present, since most shared bicycles use the GSM network, and the base stations of the GSM network have limited load capacity, in the case of network congestion, the GSM network will limitedly guarantee the quality of calls, and there is a possibility of kicking the network for GPRS communication.
The working time of the battery is also a test. Some use hubs to generate electricity by themselves, some use solar panels, and some simply use regular manual replacement and maintenance, which brings great challenges to long-term operation.
Since shared bicycles are to meet the purpose of people's convenient travel, they are distributed in a wide range and require the support of wide area network communication technology.
NB-IoT is built and operated by operators and has the characteristics of wide coverage, low power consumption, low cost, and large connections. At present, some operators have begun to gradually shut down 2G and 3G networks, and are launching NB-IoT networks on a large scale.
The NB-IoT network has wide coverage capabilities, and it is easy to cover even places where ordinary wireless network signals are difficult to reach, such as underground garages and basements. Some people put shared bicycles in the basement, which is also convenient for operators to find.
The power consumption of NB-IoT terminals is very low. Even if the device is always online, it can run for several years with battery power. Shared bicycles do not need to use external power supply, which extends the workload of battery replacement from several months to several years.
The NB-IoT base station has the characteristics of large connections. Each cell can support 50,000 users, which is 50-100 times higher than the existing 2G, 3G, and 4G mobile networks. There is no need to worry about the possibility of being kicked out of the network. GPRS ДТУ
With the standardized use of NB-IoT technology, shared bicycles can use NB-IoT technology to carry out various innovations. Perhaps, one of these innovations can bring about the ultimate improvement in user experience!
