On January 17, 2017, the sixth eevia annual China ICT Media Forum and 2017 industry and Technology Outlook Seminar with the theme of trend innovation and win-win results was grandly held in ruitu Hotel, Venice, Shenzhen. Representatives of 40 mainstream ICT media, nearly 100 industry engineers, developers and industry-leading manufacturers gathered together to look forward to the industry trend. As the Pakin sponsor of this event, Ni is a leader in the testing and measurement industry, a better method and innovator to find faults, and has been committed to helping engineers improve efficiency and accelerate innovation. At this meeting, Mr. YaoYuan, Ni's China market development manager, shared Ni's four views on the future 5g industry development and testing trends, which triggered a heated discussion among the on-site participants

ni's four views on the future 5g industry development and testing trends

iteration of emerging standards must provide better data bandwidth; While 5g communication needs to provide a transmission rate of more than 10Gbps to provide better data support for immersive applications, such as VR and ar. In addition, 5g needs a large range of object-to-object direct communication with explosive growth, which is a broader communication that has attracted much attention. Meanwhile, 5g will focus more on some mission critical applications, such as intelligent driving, telemedicine and other short delay scenarios. Therefore, Yao yuan's views also revolve around these trends

the first point Yao yuan mentioned is that prototyping is a very important step in the development of 5g, which can promote 5g from concept to implementation. So how to prototype? Among them, software defined radio (SDR) is a very important implementation means. From the prototype block diagram of SDR, we can see that on the right is the hardware components defined by the original factory, such as RF circuits, which are more standardized; The definition of polypropylene carbonate (PPC) of Boda Oriental new chemical (Jilin) Co., Ltd., the software part on the CPU, GPU, FPGA and other units on the left, is a great challenge for developers

the challenge is that the software tools that can be used are discrete. Programming languages such as MATLAB, C, c++, HTML and assembly may be useful. Systems with 5g ideas cannot be developed in one language. Therefore, researchers need to learn different tools in addition to technical ideas. To a large extent, this consumes developers' time and energy. We need to improve efficiency. Ni company has a complete set of tools to realize software radio prototyping at this point

Yao yuan's second point says that bandwidth is the most important in the 5g era in the future. To give users a good immersive experience and data experience, bandwidth is required. The history of communication is actually the history of bandwidth. From GSM in 1991 with a speed of only 9.6kbps to GPRS in 1998 with a speed of 40kpbs to the latest 4lte with a speed of 100Mbps through carrier aggregation, there will be more than 10Gbps bandwidth in the future, that is, 5g standard

the figure above is the latest instrument of Ni, which is designed for the future wireless communication to completely solve the pollution problem of express packaging; Its biggest feature is that the real-time bandwidth of the test is 1GHz. The maximum frequency range of the instrument is 6.5ghz, and the minimum frequency range is 10kHz. Its bandwidth is 5GHz. This instrument is called vector signal transceiver, which also includes FPGA to realize software customization

I am very proud of this. Because we have an FPGA, we can define the software. We can put four VSTS together. What effect does it have? You see such a frequency band, which is a super instrument with a bandwidth of more than 3.5GHz! Mr. YaoYuan said

thirdly, Ni believes that with the explosive growth in the number of IOT and wearable devices, the number of devices requiring communication tools is also explosive. Gartner estimates that more than 50billion devices will be connected to the network by 2020. In order to test the data of these 50billion devices on the physical layer, should we prepare another 50billion test devices to collect data? This is obviously unrealistic

in the face of an explosive growth of equipment, we need a more platform-based way to test and measure, and a better way to deal with it. For example, the nest of Google uses many devices of Ni internally, with various sensors, WiFi modules, ZigBee modules, battery and other parts in the structure. It looks like a circular thermometer, but it is also the brain of smart home. It can realize joint switching for air conditioners, humidifiers, PM2.5 meters and other devices. To test and measure some data such as nest, the Ni platform provides modular instruments. As an integrator, it has a variety of functions to choose from, such as VST to measure Bluetooth signal, SMU to measure power supply, ai/ao to measure i/o of various sensors, etc

fourth, Yao yuan believes that timing and delay are very important besides bandwidth. Especially in mission critical applications, there are very high requirements for delay and stability. If it is driverless, it needs to be able to distinguish between people and trees. In case of an emergency, the car can choose to hit a tree, but never hit a person. So it is necessary to have a systematic approach to how to simulate the scene and how to quickly simulate the scene after each experiment. We can use different technologies to achieve this

as shown in the figure above, the nanosecond backplane synchronization technology is accurate and time-delay, but not flexible; Another example is the LabVIEW software. Some of its data structures are characterized by high latency but good flexibility. We need to judgmentally select appropriate tools to deal with different timing scenarios

in the subsequent Q & a session, Yao yuan talked about the biggest characteristics of Ni from two aspects: first, the trend of modular instruments. Only with modular instruments can we form the sum of different test instruments. The modular architecture was first proposed by Ni and has accumulated for more than 10 years. The richness, diversity and seamless integration with software of Ni products are far superior to other competitors; The second is software definition, which has always been the concept of Ni. Ni constantly emphasizes software definition and feeding to cope with different test environments. Ni hopes to lead the whole industry through its own innovative product layout. Yao yuan emphasized
