Someone made a different NB-IoT module
Foreword: NB-IoT claims to be the next generation of Internet of Things technology , the power is great, I believe that the officials have already understood, low power consumption, wide coverage, and multiple links. However, low power consumption also brings problems. NB is non-real-time online. The server and the module cannot send data to the module in real time. There is a possibility of packet loss, and there must be a retransmission and verification mechanism. To this end, Huawei designed the CoAP mechanism, but this puts higher demands on the final application developers. Moreover, with the module, the antenna design, SIM card application management and payment, the construction of the cloud platform will affect the user to finally adopt NB-IoT to the project.
In view of this, from the perspective of making the end user faster and easier to use, “someone†has made a unique NB-IoT module, which is mainly reflected in the following three aspects.
First, the NB-IoT module is different in hardware, built-in antenna and SIM cardSupport for on-board antennas reduces the cost and annoyance of designing external antennas; supports built-in chip SIM cards to reduce size, reduce design complexity, and improve stability.
It not only optimizes the ease of use of embedded software and AT commands inside the module, but also considers the end-to-cloud application scenario from the perspective of the user, provides transparent transmission UDP mode, provides CoAP communication components, and strict retransmission mechanism to ensure data issuance. Must answer, not up to the alarm, more transparent cloud service, let users zero programming can use NB-IoT to build the system.
Working mode 1: CoAP protocol transmission cloud service CoAP protocol
The cloud service-based CoAP protocol transmission is characterized by reliable data and easy to use. Through the connection of someone to transparently communicate with the cloud, the transparent cloud will provide a secondary development interface for terminal application development.
Working mode 2: CoAP protocol transmission integrated CoAP protocol transmission
The feature based on integrated CoAP protocol transmission is reliable data and flexible configuration. Suitable for projects with their own servers, the CoAP component interface can be provided for use by the terminal server.
Working mode 3: UDP transparent transmission mode
UDP transparent transmission mode, simple to use, you need to do the application layer data retransmission mechanism.
Provide tariff management platform, IP management platform and data management platform. Module to product, just one step, and this step is the business logic of your own product. (We can only help you get here)
In addition, it is very important that this is an industrial product that can be purchased directly in Taobao Tmall and Jingdong: convenient purchase, stock inventory, ultra-simple purchase process, and a NZ-IoT SIM card.

[WH-NB73 product features]
The smart meter can be used for meters such as water, electricity, gas and heat. NB-IoT remote meter reading also inherits the GPRS remote meter reading function and also has a large capacity. The same base station communication user capacity is 10 times that of GPRS remote meter reading. Under the same conditions of use, the standby time of the NB-IoT module can be more than 10 years, and the new technology signal coverage is stronger, covering the indoor and basement.
The wide coverage of the NB73 makes it easy to find shared bikes that stay in any environment, including those parked in the basement or underground garage. And the capacity of 50,000 users per cell can be realized. The battery has been in operation for more than 10 years and the cost of the operator is low.
NB73's low power consumption and long standby operation provide data transmission all the time. NB-IoT has a huge number of connections, and the number of smoke detectors can reach more than 50,000, which can meet the massive smoke detectors at the same time. And NB-IoT is suitable for more installation scenarios, covering both indoor and basement. There is no need to worry about signal coverage and no professional maintenance installation.
NB73 can realize the data transmission of agricultural irrigation, pests and fertilization, comprehensively improve the farm production management level, reduce the traditional production cost, timely and effectively understand the growth state of crops, and improve economic benefits.
Through NB73, you can manage every street lamp in the city, and the communication capacity is large. You don't worry that the street lights are too dense and the individual can't communicate. And realize distributed control, you can master the working status, position, consumption, alarm and other information of each street lamp, reduce labor costs, improve management efficiency, and effectively save energy.
Smart Logistics usually uses a tracker with positioning and communication functions. The data upload frequency of the tracker is at the minute level or longer, the amount of data is small, and the moving rate is not high, but it requires strong coverage of the NB-IoT WAN. Power-saving mode due to signal arrival rate and low power consumption.
In the end, it is estimated that this is the only NB-IoT module that the CEO personally wrote and participated in the design.
