5g blockchain
the term "Internet of things" is mentioned almost every day in today's life. Some data show that in 2017, there were about 8.4 billion intelligent devices connected to the Internet, such as thermostats, cameras, street lamps and other electronic procts. According to foreign McKinsey & company data, this number may reach 25 billion by 2025, and the scale of the whole economy will reach 6 trillion US dollars
are you dazzled by such a huge number? Although the Internet of things technology has been widely used all over the world, its defects are graally highlighted
according to the traditional mode, the data center (server) of the equipment manufacturer often collects the information of all connected devices, which determines that the server needs to have strong operation and storage capacity. Moreover, with the geometric growth of Internet of things equipment, the cost of server maintenance will also increase greatly, which makes it difficult for small and medium-sized enterprises to maintain
at the same time, in terms of communication compatibility, the global Internet of things platforms are lack of a unified language, which is easy to cause communication obstacles between multiple Internet of things devices. This is e to the obvious fragmentation of the Internet of things instry, whether it is smart home, smart home appliances, robots, smart cars, etc., the networks they connect are fragmented and closed. In addition, the status quo of the Internet of things instry is still full of mountains, and their influence is relatively limited, so it is difficult to reach a unified standard in a short time
based on this, the standard chain team, after accumulating the previous experience from the Internet of things, combined with the characteristics of blockchain, proposed the concept of Internet of things

5g is 5g
blockchain is the third power of blockchain
it's not clear. Do you want to ask if the three logics of quantum computing
are different, and there is a little sense of mutual promotion
5g solves the problem of wireless transmission speed, which is many times faster than 4G
blockchain was formerly PPP protocol, It is the point-to-point transmission protocol
used to solve the congestion problem of the central node. Quantum computing to improve the download speed is a breakthrough of Moore's law, which can solve the limit problem of computing speed in the limited space
for more information, please refer to this article, what is blockchain, can you explain it easily
in a word, blockchain is decentralized, using the trust protocol between distributed data nodes to achieve data sharing and mining upgrade. Artificial intelligence covers a wide range, including language recognition, image recognition, machine learning, intelligent logic and many other disciplines.
Anyone can own bitshares by investing in bitshares PTS and bitshares AGS. AGS (angel shares) is a share of angel investment fund, which is used to support the research, development and creation of technologies related to bitstocks. A total of 10000 AGS will be given to those who donate Angel funds on the same day according to the proportion of donation to the donation on the same day. Bitshares PTS is a clone of bitcoin that allows you to mine and trade your support for the bitshares ecosystem. Bitshares AGS and bitshares PTS both contain a social consensus, that is, in the future, all bitshares blockchains should allocate at least 10% of each to AGS and PTS shareholders in Genesis block to give back their support to the ecosystem of bitshares
On June 6, 2019, China Telecom, China Mobile, China Unicom and China Radio and television, which are the most popular 5g procts, ushered in new progress and won the first batch of 5g commercial licenses issued by the Ministry of instry and information technology. Since then, China has officially entered the 5g era, and 2019 is also recognized by practitioners as the "first commercial year" of 5g
on December 7, 2018, MIIT agreed that China Unicom Group would use 3500mhz-3600mhz frequency from the date of notification to June 30, 2020 to carry out the fifth generation mobile communication (5g) system test nationwide
on December 10, the Ministry of instry and information technology officially announced that it has issued the license to use the medium and low frequency test frequency of 5g system to China Telecom, China Mobile and China Unicom. This means that the frequency resources that the basic telecom operators must use to carry out 5g system test are guaranteed, which sends a clear signal to the instry and further promotes the maturity and development of China's 5g instry chain
extended data:
network features:
1. The peak rate needs to reach the Gbit / s standard to meet the high-definition video, virtual reality and other large data transmission
2. The delay level of air interface should be about 1ms to meet the real-time applications such as autopilot and telemedicine
3. Large network capacity, providing the connection capacity of 100 billion devices, meeting the requirements of Internet of things communication
4, spectrum efficiency is more than 10 times higher than LTE
Under continuous wide area coverage and high mobility, the user experience rate can reach 100mbit / s The flow density and connection number density increased significantly
