Wireless industry experts have said that with the popularity of the Internet of Things, we must deploy 5G networks by 2020. But the problem is that we don't know what the 5G network is. We haven't used the 3G mobile phone for a long time, and 4G is coming again. Isn't 5G not far from us? The answer is no, because at the moment we are not sure what 5G is. However, the wireless industry has plans for what 5G should be able to do. You may have heard of the current term "Internet of Things". The so-called "Internet of Things" is a network of various devices used to describe the future, such as cars, clothes and home appliances, which can communicate with each other in a wireless manner. For the Internet of Things, the current wireless industry needs to address the issue of how these communications are conducted. The current consensus is to pass the 5G network. Industry experts said that 5G must be deployed before 2020, although we are still not sure what 5G is. Mike Haberman, vice president of network support for Verizon Wireless, a US mobile operator, said at the Wireless Industry Conference in Las Vegas on Tuesday: "I think we need to develop 5G requirements. What problem does 5G have to solve?" In the next few years, billions or even billions of devices will be connected to the Internet via mobile networks. But the current question is which spectrum resources will be used by 5G networks? What bandwidth standard is chosen? What infrastructure is used? These are still to be determined. Aicha Evans, vice president of Intel Platform Engineering, said energy efficiency is an important consideration in the development of the 5G standard. Evans said: "This is the social responsibility of all of us, otherwise we will not burn the earth." Chris Pearson, president of 4G Americas, said that by 2020, 50 billion devices will be connected to the Internet of Things, so the demand for electricity is huge. In addition, these devices will be connected via mobile networks, so mobile broadband will become the core of the future IoT society. The current Internet of Things is mainly focused on "smart home" products, such as Nest Labs' thermostats and "connected cars" technology from companies such as Apple. Arun Bhikshesvaran, chief marketing officer at Ericsson, said that in the short term, operators can still meet the growing traffic demands through the current LTE 4G network. But by 2020, a variety of network elements will undergo a fundamental transformation. Currently, the wireless industry is still trying to determine which devices will drive data traffic growth in the next few years, just as the consumption of data by smartphones in the 3G and 4G era. The challenge is to have a variety of devices accessing the network in the future, from emergency services that require instant access to relatively unimpressed entertainment services. Bi Shilang said: "At that time, we will see a new Internet use case."
