The Internet of Things (IoT) market is attractive and attracts vendors to steal business opportunities. One of the important pieces of the IoT architecture, communication technology, is also due to the large number of demanding and energy-efficient nodes in the Internet of Things. The wide area network (LPWAN) is highly regarded. To use this technology in addition to Sigfox, LoRa, etc., the 3GPP also does not compromise the use of licensed spectrum of LTE CAT-M and NB-IoT. At one time, the IoT low-power wide area network market was buzzing and the various technologies were making every effort to expand their forces. However, as global telecommunications operators started to start successively from the end of last year to provide NB-IoT services, they originally lost. The starting point of NB-IoT, there is a lot of things to come from behind.
According to Far Eas Tone, an IoT product and program management coordinator of the Enterprise and International Business Group, NB-IoT will come to power and will bloom. He further explained that the Internet of Things can be divided into two large blocks. One is a key task. Mission Critical IoT; Massive IoT application. The former requires a large amount of network data transmission, and the transmission speed is fast and low delay. The latter requires extensive sensing. Node, longer battery life, and NB-IoT is 3GPP to build for massive IoT applications.
Even if the low-power wide-area networks have been 'stewarded' by the two camps of Sigfox and LoRa, and have their own 'grand coffee' supporters, NB-IoT is leveraging its strengths and the global telecommunications industry's strong push for future technology. The forces will surely go far beyond other low-power wide area networks.
Wang Yiren analyzed why NB-IoT is a rising star. First of all, NB-IoT is a technology developed and introduced by 3GPP. There is a strong ecosystem built around 3GPP. Furthermore, NB-IoT can be easily and reliably implemented. With the integration of high-security LTE systems, suppliers do not have to spend huge sums to build new networks and hardware. Existing equipment only requires software upgrades. Third, NB-IoT uses licensed frequency bands and there is no need to worry about unlicensed bands. External interference problems faced; Finally, the NB-IoT has a gain of 20 dB over the existing network, which not only can cover many areas, but also can significantly increase the depth of signal penetration.
From the point of view of device manufacturers, why should the industry choose to import NB-IoT? Wang Yiren believes that in addition to a strong ecosystem, better coverage, better scalability, and more comprehensive security mechanisms, NB- IoT is selected as a new technology adopted by global telecommunication operators. That is to say, the technology allows telecommunication operators to provide good management mechanisms, quality services, and low upgrade difficulty. Even if NB-IoT has a device moving speed Faster, the quality of network connection is not good, but the nature of NB-IoT technology is not designed for high mobility. If the network shelf can be built better, this problem can be solved, so this small limit is Will not affect the global telecommunications industry or other related manufacturers of the technology investment.
The global NB-IoT service has been gradually launched. At present, more than 33 NB-IoT networks have been built. As for the progress of NB-IoT in Taiwan, Wang Yiren stated that the construction of NB-IoT of Far EasTone Telecom has now been completed. The coverage rate of % is expected to cover all Taiwan in May this year, and the initial public sector demand for NB-IoT will happen fastest, and will be extended to corporate and business services. In addition, Chunghwa Telecom announced the company's NB-IoT service. , Has been open beta in January 2018, will officially launch commercial services by the end of 2018.
