The so-called 5G refers to the fifth generation mobile phone communication standard, also known as the fifth generation mobile communication technology. Since 2013, discussions about 5G mobile technology have gradually floated. In this, the mobile chip industry giant Qualcomm serves as a representative of the early participation in R & D tests, interprets the research and development schedule, standardization model, and industrial chain relations in the 5G field.
The development of mobile networks started from 1980, and in 2010, it was officially entered 4G era, and now I am moving toward 5G. Qualcomm first mentioned their vision, that is, through the intelligent connection platform, the world is realized.
In Qualcomm eyes, 5G should be a network platform with a unified connection architecture. Relying on the future unified connection platform, achieve different frequency band types and diversified service deployments through a new technology, ultimately achieve development of 5G.
Qualcomm focuses on three different application scenarios of the 5G network.
First, 5G enhanced mobile broadband: there is a greater throughput, low delay, and more consistent experience.
5G Enhanced Mobile Broadband is mainly reflected in the following areas: 3D ultra HD video remote presentation, perceived Internet, ultra HD video stream, high-demand field environment, broadband fiber users, and virtual reality.
Second, 5G Key Business Services: Have better reliability, low delay, and more popular.
Key business services are primarily applied in automatic driving, robots, energy intelligent grids, industrial automation, aircraft, and medical fields.
Third, 5G massive network level: with energy saving, low complexity, and remote control.
Massive Internet applications include smart cities, smart home, public facilities, wearable equipment, remote sensors, or drives, and target tracking, etc.
Qualcomm said that 5G is a uniform null for the next 10 years, with optimized waveform, universal flexible framework, and advanced wireless technology. In general, the lower the frequency, the better the coverage, but the bandwidth capacity is also small. As the frequency increases bandwidth capacity is also growing.
Qualcomm Unified 5G design supports all spectrum types and frequency bands, including authorized spectrum, shared authorized spectrum, non-authorized spectrum.
If divided according to the band, 1GHz corresponds to the massive network; 1GHz to 6GHz facing the enhanced mobile broadband and key business; 6GHz or more, such as millimeter wavefronts to the ultimate moving bandwidth.
The wireless / OFDM technology and chip technology in the high-end stage are relatively leading. In the future, it can develop 5G technology in the future, and they can also promote 5G from standardization to trade in the system approach. In addition, Qualcomm provides 5G. Experience and scale recommendations required.
It is reported that in terms of 5G prototypes, Qualcomm has released two platforms this year, respectively, the prototype system of 6GHH-ordered 6GHz, and the 28GHz end-to-end system platform, theoretical network speed test, 5G is more than the existing 4G LTE is 100 times faster.
Initial 4G and 5G dual connection mode development
Talking about the development of 5G in the future, Qualcomm believes that the 5G development form is 4G and 5G dual-connected mode, 4G as a base layer, 5G as a reinforcing layer, and the future with 5G has gradually replaced 4G. In addition, multi-connections, multi-mode technology also play a role in 5G development, such as allowing the device to support 5G, 4G and WiFi access seamless switching.
In addition, modems and radio technology will help 5G development. Qualcomm is currently promoting the 5G NR standardization process, the goal is released in 2019, and the high-pass high-end will be repeatedly tested through prototypes and partners.
Qualcomm summary said that the natural development law of the mobile network is a 10-year cycle. Although China from 4G to 5G time is relatively short, the foreign market has been popularized from 2010. Considering South Korea held a Winter Olympics in 2018, Japan held a Summer Olympics in 2020, which also promoted the accelerated spread of 5G networks.
In addition, mobile phone manufacturers and operators will also increase their efforts to meet 5G networks. However, due to the increase in bandwidth, the challenge of the equipment baseband and power consumption will be large, and the internal number of the mobile phone needs to increase more antenna, so mobile research costs will be further increased. Qualcomm said that the future will help these mobile phone manufacturers complete the design of the product structure.
