The 5G communication network developed a shot to start. Telecom operators and measurement instrument developers have recently unveiled preliminary results of 5G technology research and development, including the successful establishment of 5G virtualized cloud wireless access network (C-RAN) platform, and the launch of related technology testing and verification solutions. It will help speed up the 5G network prototyping and achieve the goal of starting commercial use in 2020.

5G became the highlight of the 2015 Global Mobile Communications Conference (MWC). The demand for mobile broadband network bandwidth continues to soar, which has stimulated telecom operators/equipment operators, chip vendors and national standards research organizations to invest in 5G technology, including China Mobile, Telstra, Ericsson and Altera. In 2015, MWC released the future 5G research project, as well as the initial technology and field test results, will be the next generation of mobile communication network development beef.

After the long-range evolution plan (LTE) and LTE-Advanced, the 5G wave swept the communications industry, and the development of 5G standards and related network access technologies also quickly became on the table, which will become the focus of investment and R&D in the communications industry chain in the next few years. In order to seize the market opportunity, the world's major telecom operators and equipment manufacturers all have positive card slots, officially detonating the 5G revolutionary wave.

Telecom operators and measurement instrument developers successfully established 5G virtualized cloud wireless access network platform

Among them, China Mobile has teamed up with Altera to demonstrate the 5G virtualized cloud wireless access network (C-RAN) platform at MWC in 2015, which will help accelerate the formation of next-generation centralized and harmonized 5G wireless networks to significantly increase users. Networking experience at the edge of the network signal while achieving higher channel capacity, spectrum efficiency, and reduced network power and deployment complexity.

Chih-Lin I, chief scientist of China Mobile Research Institute, said that China Mobile Research Institute (CMRI) first published the C-RAN concept. It has been about five years since now, and it is widely believed in the industry that this solution is an indispensable element of 5G network. Altera is selected as a key partner to introduce advanced field-programmable gate array (FPGA) technology and design support to meet the stringent requirements of power, computing power, flexibility and cost of next-generation wireless networks. To the 5G generation.

It is reported that China Mobile Research Institute and Altera established a strategic partnership in 2014. The two parties jointly use FPGA to optimize C-RAN system data processing, component interconnection and backhaul data transmission. After nearly one year of efforts, it can only be in 2015. MWC presents a complete 5G virtualized network design concept. Coincidentally, Ericsson and Telstra also took a fancy to the MWC exhibition's indicative significance for the communications industry, and cooperated to unveil 5G wireless access and core network conceptual architecture, and announced that it will use Ericsson's cloud system, router 6000 series, and evolutionary packet. Core elements such as core (EPC) network technology, software defined network (SDN) controller, and IP Multimedia Subsystem (IMS) are invested in 5G project research and field testing.

Mike Wright, director of the network division of Telstra Group, said that although the 5G world has not yet arrived, it is very important for industry chain operators to start basic work such as standards and network verification to shorten the technology learning curve. In addition to following the general standards developed by 3GPP, Ericsson and Telstra will also define specifications that fully comply with Telstra's future 5G network architecture and service requirements. Not only that, the two companies plan to carry out 5G technical verification at the Swedish Ericsson Advanced Technology Center in the second half of this year, and then will launch 5G field testing in Australia.

Hakan Eriksson, president of Ericsson Australia, New Zealand and Fiji, stressed that 5G networks need to be implemented in an end-to-end manner, including devices, wireless access and core networks. The company works vertically with Telstra. It will be able to gain an in-depth understanding of the impact and benefits of various innovative technologies on the network, as well as deploy 5G machine type communication (MTC) as soon as possible, so that utilities, logistics and agriculture can also join the future IoT machine-to-machine (M2M). ) A part of communication. In addition to telecom operators and equipment factories, R&S, National Instruments (NI) and other measuring instruments manufacturers have spared no effort to promote 5G related testing technology to seek a new wave of development.

It is highly probable that 5G is likely to operate in the millimeter wave (mmWave) band, subverting the existing mobile communication network. R&S has released a series of solutions supporting the millimeter wave broadband test in 2015, including vector signal generator and digital oscilloscope. And signal and spectrum analyzers, to help communications chip vendors and equipment manufacturers accelerate the integration of 5G design.

R&S said that the company is actively involved in the 5G Forum in Korea, the 5G InnovaTIon Centre, the NGMN 5G IniTIaTIve organization, and the 5G lab in Technische Universitat Dresden, Germany. Master the direction of technology evolution and deploy appropriate test plans as early as possible. At this stage, the company's signal and spectrum analyzer is equipped with a special software solution, the analysis bandwidth can be increased to 2GHz, support up to 67GHz frequency range, suitable for the current 5G mobile network prototyping, and can meet the test challenges that may be faced in the future.

In addition, the R&S signal generator has been able to produce 40 GHz test signals, and with an external upconverter to provide higher frequency range signals; the company's test configuration at MWC 2015 achieved 60 GHz broadband signal generation, Help 5G chip and system verification.

Plastic Package Diode

Plastic Package Diode.Among the electronic components, a device having two electrodes allows only the current to flow in a single direction, and many uses apply its rectification function. The Varicap Diode is used as an electronic adjustable capacitor. Most of the diodes have a current directionality that we often call the "Rectifying" function. The most common function of a diode is to allow only current to pass in a single direction (referred to as forward bias) and block in the reverse direction (referred to as reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
