When 4G (fourth generation mobile communication technology) commercialization has not yet been achieved in mainland China, 5G (fifth generation mobile communication technology) has entered the media and public view. Samsung Electronics recently announced that it has achieved a key breakthrough in the field of 5G technology, and is expected to achieve a transmission rate of 10Gbps in the future, and plans to achieve 5G commercial use in 2020.
But what exactly is 5G? What will 5G bring to the whole society? Samsung did not give an answer. However, in the view of Ericsson, the world's largest telecommunications equipment manufacturer, 5G technology will completely bring human society into the network society, thereby realizing communication between people, things and things, and people and things.
In the 5G era, the wireless communication field will probably no longer have the similar TD-SCDMA and WCDMA, CDMA2000, and WiMax in the 3G era; the TD-LTE and LTE-FDD standards battle in the 4G era, and the global 5G technology is expected to share a standard .
What is 5G?
When Samsung announced its 5G technology breakthrough progress, the public generally believed that the so-called 5G is a mobile communication technology with a transmission rate of up to 10Gbps, which also includes the famous American Time magazine.
After Samsung announced that its 5G technology had made breakthrough progress, Time magazine published an article to see the decline of 5G technology. "Time" claims that 5G technology only improves the transmission rate of wireless communication, but it does not solve the traffic storm problem brought by the future mobile Internet. Old problems such as network congestion are still not solved in the 5G era.
"In fact, 5G is different from 4G, 3G, and 2G. 5G is not a single wireless access technology or a few new wireless access technologies, but a variety of new wireless access technologies and existing wireless access. Technology (4G backward evolution technology) integrated solution generic term. To a certain extent, 5G is a true converged network. "Ericsson researcher and EU METIS 5G project overall leader Afif Osseriran accepted Phoenix Technology yesterday Said during the interview.
Afif Osseriran said that the key purpose of 5G is to build a network society, which means that in addition to meeting the needs of ultra-high-speed transmission, 5G also needs to meet the requirements of ultra-high capacity, ultra-reliability, and accessibility anytime, anywhere. In order to solve many problems such as "Traffic Storm" mentioned by Time magazine.
According to the prediction of the European Union, as core services such as e-banking, e-learning and e-health will continue to be popularized and more mobile. The development of the online society will bring a surge in mobile and wireless traffic. This means that by 2020, data traffic will increase 1,000 times over 2010. In addition, the hybrid communication between man and machine will drive traffic growth, and it is extremely important to efficiently and conveniently and securely access and share information. The emergence of the Internet of Things and other new innovative applications will spawn tens of billions of connected devices, creating unprecedented diversity requirements and application scenarios related to wireless connectivity.
It is for this reason that the European Union established a 5G research project in November 2012-METIS (key technology for the field of wireless mobile communications in the construction of the information society in 2020). It is reported that the project is composed of 29 members, including Ericsson, Huawei, Alcatel Lucent, Nokia Siemens, France Telecom, Telefonica, NTT docomo and other major global telecommunications equipment manufacturers and operators, as well as AAU, Aalto, CTH, etc. More than ten universities and research institutions, even BMW Group, Anite, Elektrobit, etc. in the non-telecommunications industry.
The goals set by the EU METIS 5G project team for 5G communication technology include: In terms of capacity, 5G communication technology will achieve a 1000-fold increase in mobile data traffic per unit area compared to 4G; in terms of transmission rate, the typical user data rate is increased by 10 to 100 times. The peak transmission rate can reach 10Gbps (4G is 100Mbps), and the end-to-end delay is reduced by 5 times; in terms of accessibility: the number of networked devices is increased by 10 to 100 times; in terms of reliability: low-power MMC (machine type) Equipment) battery life increased by 10 times.
Afif Osseriran said that METIS will explore to achieve the above goals of the EU 5G project team by increasing capacity, improving energy efficiency, reducing costs and improving spectrum utilization, so as to fully support the needs of the network society.
Semiconductor Disc Devices(Capsule Type)
Semiconductor Disc Devices(Capsule Type) is the abbreviation of thyristor, also known as silicon controlled rectifier, formerly referred to as thyristor; thyristor is PNPN four-layer semiconductor structure, it has three poles: anode, cathode and control pole; thyristor has silicon rectifier The characteristics of the parts can work under high voltage and high current conditions, and their working processes can be controlled and widely used in electronic circuits such as controlled rectifiers, AC voltage regulators, contactless electronic switches, inverters, and inverters.
