Wang Haowen, General Manager of Shanghai Zhongxin Core: NB-IoT Test Solution Development Challenges and Applications

On December 2nd, at the Smart Internet Forum of the 3rd IoT Conference hosted by e-sports enthusiasts, Wang Haowen, deputy director of the Application Testing Department of the Chinese Academy of Sciences' Sensor Network and Communication Key Laboratory, was also the CEO of Shanghai Zhongxinxin Information Technology Co., Ltd. Wang Haowen, on the latest popular NB-IoT technology, explained the latest development of NB-IoT test solution development to more than 200 audiences.

Among the many technologies in the Internet of Things, NB-IoT technology is just one of them. Wang Haowen, general manager of Shanghai Zhongxin Information Technology Co., believes that NB-IoT technology has considerable development prospects.

He reviewed the history of entrepreneurship. “In 2015, my friends and I founded Shanghai Zhongxinxin Information Technology Co., Ltd., focusing on the testing of RF and communication solutions. Our startup team consists of the Key Laboratory of Sensor Networks and Communication of the Chinese Academy of Sciences, and the National Instruments. NI co-built the communication laboratory, which was originally in Zhangjiang and now in Zhangjiang and Jiading. Our experimental equipment is more than 50 million."

Mr. Wang pointed out that they are concerned about the two main reasons behind the NB-IOT technology: In 2015, when Huawei Research Institute was doing LTE-M (using LTE technology to achieve the connection between things and things), I hope to find a team to do LTE-M. Let's learn from each other. We are still determined to make this instrument: First, we have long-term accumulation on the LTE technology route; second, we have been exposed to LTE-M technology early in the morning, and we did not foresee that this technology is so hot today.

NB-IoT technology features, five major advantages: low power consumption, wide coverage, deep coverage, a hundred times of coverage, wide coverage requires verification of measuring instruments, we just provide solutions.

In 2020, the IOT market occupied by NB-IoT technology will account for a quarter of the IOT market. 2017 is the first year of NB-IoT, Huawei HiSilicon will launch NB-IoT commercial chip. Considering that commercial chips come out, commercial machines will come out. We will test the NB-IoT instruments at the end of 2016 according to market forecasts.

Mr. Wang analyzed the three major challenges faced by the NB-IoT test solution:

1. It is impossible to do NB-IoT testing with the existing method. This is a new technology.

2, NB-IoT is a wide coverage, is a technology for meter reading, gas meter reading business features a day to read the table once, the difference between the two days of data is not too large, the measuring instrument should be simulated on the terminal simulator 50,000 to 100,000 users use this magnitude to test the pressure of the base station, which is different from LTE.

3, although the chip is said to be 1 US dollar, but all tests can not be less, there are protocol testing, network simulation of mutual exchange test, resource management test, RF test, air interface test, power test, production line test.

The NB-IoT test solution provided by Shanghai Zhongxin Information Technology Co., Ltd., the first one is for the physical layer. In the first quarter of 2017, the company will also test the NB-IoT protocol layer and provide comprehensive testing. Demand.

From the market perspective, there are three stages of testing: 1, testing in the prototype phase; 2, laboratory testing; 3, field testing. Power consumption testing is difficult, our instruments are not aimed at this point, we mainly test for RF.

5V Wall Charger

5V Wall Charger are wall plug adapters with 5V output, which are popularly used for tablets and mobile phones etc.

When you buy the wall mount Adapter, you should choose right plug. Besides, you should see the output current and dc plug size according to your device, the normal dc plug size are 2.5*0.7, 3.5*1.5, 5.5*2.5, 5.5*2.1, mini USB and MICRO USB etc.


For Yidashun's wall power adapter charger, there are different plugs for choose like: EU plug, US plug, UK plug, Australia plug, Argentina plug and Brazil plug and so on, which used in different countries.

Yidahsun's wall charger is with smart IC to protect your device with over current protection, over load protection, short circuit protection, over heat protection.
