It is understood that Huawei CableFree technology has broken through the bottleneck of current antenna design and effectively improved all aspects of antenna capabilities.
1)5G for better high frequency coverage. 5G uses a higher frequency band and needs higher antenna gain to provide higher wide coverage. At the same time, 5G network coverage needs multi-band cooperation, such as using 1.8GHz/2. 1GHz as 5G uplink, and high-frequency coverage plays an important role in the continuity of 5G experience. The wireless technology improves the radiation efficiency of the antenna by about 20%, thus improving the coverage quality.
2) Meet the greater output power demand brought by more frequency bands and more channels in the 5G era. The demand for large capacity and high speed in the 5G era requires the application of more spectrum and higher-order MIMO, and the antenna carrying power will increase from 500 watts to 600 watts or even more. CableFree technology improves the antenna power capacity by more than 80%, which meets the greater output power demand in the 5G era.
3) The weight of the antenna is reduced, and it is easy to install and deploy. The high integration of antenna components effectively reduces the weight of the antenna. Taking the 6-band antenna as an example, the overall weight is reduced by about 10kg, and the weight of the multi-band antenna is controlled within 50kg, thus avoiding the use of cranes, simplifying the installation process and saving the installation cost.
4) The antenna PIM performance is better. CableFree technology reduces 80% of the screws and welding points inside the antenna, reduces the risk of PIM and ensures the long-term stability of PIM; Its new architecture and technology improve the proportion of production automation and ensure better consistency of mass production performance.
Cable-free technology adopts cable-free feed design and integrated phase shifter design to improve antenna integration and antenna performance. CableFree technology will be applied to Huawei Munich Pro, Golden Mini and London Pro series antennas, as well as 32T32R Massive MIMO and other products.
According to the joint research conducted by the Technical University of Berlin and the German intellectual property research company Iplytics on June 5,438+10 this year, Huawei has the largest number of 5G patents in the world, * * * has 3 147 5G patents, followed by Samsung Electronics, * * * has 2,795 5G patents and ZTE has 256 1 5G patents.
Previously, Ren, the founder of Huawei, said that about 20% to 30% of the company's annual expenses are used for research and innovation, and 70% is used for product development.
In the past ten years, Huawei has invested more than 600 billion yuan in R&D. Last year, its R&D expenditure was as high as131700 million yuan, accounting for 15.3% of the annual sales revenue. It is estimated that the investment this year will be more than 20 billion US dollars.
