The 5G era is coming, and there are different opinions about 5G. The author debates whether 5G is considered exaggerated or not. How do text message service you view 5G? Some people, including me, feel that 4G is enough. When you go back in time to 3G and look back at how people thought about 4G then, the results are the same as how we think about 5G now. And draw the conclusion: In fact, everyone's vision is limited by their living environment and the era in which they live, and the role and field of use we imagine from a limited vision may not be consistent with its actual impact; Even if some technology didn't show its importance at the time, maybe it provided a technology ladder for other important technologies. So let's stretch the timeline a bit further. 1. Looking back on the past 1. Cons: For most people, 4G to 5G is just 1080P to 4K In fact, most people did not expect the outbreak of live broadcasts and short videos. even became one of the Internet giants on an equal footing with BAT. China has ushered in a new Internet pattern. When returning to 3G can not get the text message service answer, then let's extend the time a little bit back to the 2G era. What about 2G? At that time, mobile phones were small, with small screens and keyboards. We use it to send messages, make calls, and set cell phone ringtones. The methods of information transmission include text, sound, image, video (multiple pictures are played in frames), video (sound is added on the basis of video), and their information density and data size increase in turn. At this time, the speed supported by data transmission can only transmit text and voice information. When 3G arrived in 2010, our screen became a little bigger. In this era, most of them are flip phones, with a screen and a keyboard. Apple has even launched its first 3G full-screen smartphone. At this time, in addition to basic functions, we also use it to browse the web, listen to songs, and play games. In text message service the 4G era in 2015, almost everyone has a full-screen smartphone in their hands, and video messages also account for an increasing proportion of our daily lives. Looking back in this way, it is not difficult to find that the information transmitted by mobile phones has expanded from text and audio information with the least information density to more dense forms such as images and videos. Humans naturally prefer the presentation form with higher information density in the same time, but the data transmission speed of mobile phones in the 4G era has already met the requirements of the highest form of information density.
