September 2 (January) In the long history of the telecommunications industry, there has been competition and convergence of technical standards such as TDD and FDD, NGN and NGI, Bluetooth and ZigBee. In recent years, the development of Internet of Things in full swing, the world has seen its huge market prospects. In the field of wide area IoT communications, NB-IoT has developed rapidly in recent years. Insiders believe that NB-IoT will play the role of the "Terminator" of Low Power Wide Area Network (LPWAN) technologies such as Lora and Sigfox.

On this topic, he interviewed Zhang Xiaobo, CTO CTO. He said that due to the vigorous publicity of NB-IoT, many people think that it will become the "Terminator" in the development of other low-power wide area network technologies and feel scared. actually not. NB-IoT development, making the entire market for low-power wide area network has been stimulated demand, LoRa this low-power wide area network technology but faster, more limited market awareness. Recently, the only company to LoRa maximum free distance parallel test, reaching 21.5 km, causing a tremendous industry response, the customer has also increased a lot.

Zhang Xiaobo believes that any technology can not completely capture the market, NB-IoT will play a catalytic role in the development of the entire industry, to some extent, NB-IoT and LoRa belong to two camps. Because NB-IoT relies heavily on the carrier's infrastructure for protocol interoperability, LoRa is a more flexible, autonomous network that can be deployed wherever it is needed.

Talking about the market differences between the two, Zhang Xiaobo said NB-IoT mainly depends on the network coverage, but in many harsh conditions, the operator's infrastructure is not fully covered, these blank areas is the LoRa market. In addition, the entire IoT area, fragmentation situation is very serious, a variety of applications, which gives LoRa development has brought many opportunities. LoRa can be deployed at any time, regardless of location, very flexible. NB-IoT and LoRa must be co-existing and complement each other. At the same time, NB-IoT is not just competing with LoRa, but competing with other technologies.

NB-IoT is growing rapidly and is expected to be commercial on a large scale in 2017

Triggering the discussion of this technology is the rapid development of NB-IoT. In recent years, NB-IoT is indeed one of the hottest technical terms in the communications industry. In the promotion of many communications companies, its development is very rapid. In particular, in June 2016, the NB-IoT standard was adopted by the international organization 3GPP, and the domestic NB-IoT industry standard is expected to be released by the end of 2017. It is expected to be commercially available in early 2017.

In the industrial chain, Huawei officially released its end-to-end NB-IoT solution to the world at the end of June 2016, and the solution is planned to be officially launched in September this year. Huawei also plans to conduct large-scale commercial trials in the fourth quarter and will The end of December this year, officially launched large-scale commercial. In fact, NB-IoT is supported by a number of telecommunications companies such as telecoms equipment providers such as Ericsson, Nokia, Huawei and ZTE, large telecom operators such as AT & T, China Mobile and China Unicom, as well as chip solution providers such as QUALCOMM .
