The future of communication

Future communication tools must revolve around the Internet. In the future, all voice calls will be free. Traffic is an inevitable trend in future use. Future communication tools will be diversified, as small as a ring or a watch. It can be used for half a month or more on a single charge, and the communication tool has a projection function!

1. Optical transmission communication

1. Optical transmission technology will create amazing information transmission speed

Our Stone Age ancestors used simple gestures , roars, body language, fire or smoke signals, reflections to convey information, the communication rate is approximately one visual or sound signal per second. Today, the information transmission speed of 1 terabits/second indicates that humans are overcoming the time barrier and are about to achieve true real-time communication.

A transmission speed of 1 terabits/second means that 200,000 medium-thick books, 200,000,000 fax pages, 660,000 video conferences, or 20,000 files can be transmitted simultaneously in 1 second TV show. The amount of information a person is exposed to in his lifetime is equivalent to approximately 20 billion bits. If the advantages of today's communication technology are fully utilized, this amount of information can be transmitted in less than 1 second. In other words, everything you have thought and said your whole life can be transmitted from one place to another before you can even blink.

Now, Bell Labs has used 82 different wavelengths to achieve a transmission speed of 3.28 terabits/second, and some laboratories have demonstrated demonstrations of 10 terabits/second. As long as the computer's processing speed can keep up with this jaw-dropping transfer speed, the Library of Congress's 24 million volumes can be transferred in about 18 seconds. This speed is fully achievable according to the current level of development.

Tasks that used to take people a lifetime to complete with their own arms can now be solved in a matter of seconds. It is expected that by 2010, the computing power of computers will catch up with the human brain.

2. Satellite Communications

The improvement of satellite services and the reduction of prices will promote the wider application of wireless communications.

Early satellite receivers were expensive luxuries beyond the reach of most people, and the antennas required to receive signals were so large and unsightly that in many places municipalities and landlords banned their use in homes. . That's different now. A dish antenna with a diameter of 1 meter can be purchased for only a few hundred dollars, and satellite communications have become an important industry. In 1998, there were 1,700 commercial launches of satellites. The value of communication satellites launched in the next 10 years will reach 140 billion US dollars, plus 70 billion in launch system and ground service fees; by 2007, the number of satellite phone users is estimated to reach 32 million, total annual revenue will reach 31.6 billion U.S. dollars; by 2008, annual revenue from telephone calls, high-speed Internet access and other information transmission generated by satellites will reach 150 billion U.S. dollars.

3. From "IoT: Internet of Things" to "Internet of Everything (IoE: Internet of Everything)".

The world may no longer need mobile phone numbers It's Wi-Fi, and the reliance on phone calls and text messages is getting smaller and smaller, until one day the phone technology is completely sealed, just like the telegraph. At the same time, words such as mobile phone numbers and phone numbers will appear in history textbooks. In the future, your mobile phone will no longer need 2G, 3G, 4G, 5G... signals, but Wi-Fi. At that time, Wi-Fi technology will also be upgraded and popularized, and Wi-Fi technology will be seamlessly connected and ubiquitous. .

When wireless technology breaks through, wired broadband will also come to an end. At that time, mankind will enter the era of comprehensive Internet of Things communication: it will no longer be communication between people, but more between people. Internet communication of things, things and people, and things and things.
