When it comes to the Internet of things (IoT), many people will simply assume it‘s just a combination of the Internet and sensors. In fact, the Internet of things and the Internet are not a simple relationship. They have their own development history, independent application areas, independent users and independent network architecture. The Internet of things (IoT) is an important part of the new generation of information technology and an important stage of development in the "information age". With the continuous maturity of related technologies, the Internet of things has begun to show new vitality, which is called the third wave of the world information industry development after computers and the Internet.

With the network connection capability of 5G with large bandwidth(HT6000 DWDM/OTN System) and low time delay, the Internet of things can get a great play space. Although 5G brings a lot of opportunities to the Internet of things, it is not necessarily the Internet of things. IoT often requires multiple technologies to work together, including narrow band IoT, LPWA and various technologies to realize relevant applications, rather than being limited to 5G.

Although the Internet of things (IoT) is surging and gaining wide social attention, the era of the Internet is not over, and IoT is not likely to replace the Internet at this stage. It can be predicted that in the future, the Internet, Internet of things and mobile communication network will co-exist and complement each other to build an intelligent future society together.
