5G times small base station how to "change face"?

'In the era of 5G, indoor coverage is more important, and small base stations are becoming more prominent as a result.' Ding haiyu, director of the wireless research institute of China mobile research institute, said at the industry's first commercial 5G cloud station technology salon in Shanghai on MWC19. He believes that there are three main solutions for the construction of cell divisions: the pure coverage scenario gives priority to the old traditional cell division scheme, the experience scenario gives priority to the cloud small station scheme (extended base station), and the super-capacity scenario gives priority to the distributed base station scheme.


It is reported that as early as 2017, the China mobile research institute began 5G small station project, research based on the extended base station of lower cost indoor distribution coverage solution. Beijing telecom has been deeply engaged in the field of wireless optimization for more than 20 years, and now ranks first in the domestic market of network optimization, extended base station and integrated small base station. Comba telecoms network products division general manager luo diffuse Jiang Jieshao said that companies work closely with China mobile research institute, established a perfect 5 g signal source spectrometer, 5 g, 5 g terminal emulator supporting instrumentation development tools such as resources, under the support of China mobile research institute and Intel, created Firstcall at the end of 2018. IoT, lab and field tests were completed this year and are now commercially available.


5G has a lot of demand from vertical industries, which requires small base station manufacturers to deeply integrate with the industry. Ding haiyu predicted that 'the future 5G small base station market may be partly a sub-market, and partly a market of various industries, that is, small base station manufacturers will be scattered to different industrial applications, rather than one system to conquer the world. Whoever is more integrated with the industry wins.'


5G is not only a new generation of technology, but also the DNA and cornerstone of future innovation platforms. Zhang xiaowen, Intel's chief wireless software engineer, said the x86 small base station chip solution, a network system chip designed specifically for 5G wireless access and edge computing, will bring Intel's computing architecture to wireless access to base stations and allow more computing functions to be distributed at the edge of the network. 4G small base station is based on general SoC chip, compared with 5G 'cloud' small station, the performance is greatly improved, the platform is more open, and it can provide more flexible value-added service capacity. The key design includes the following elements: scene-based function and performance requirements, open platform, IT system architecture, intelligent management platform. 'In the era of 5G, there has been a shift from signal coverage to capacity demand coverage. 5G small base stations are bound to explode, but the demand is gradually released,' luo said. Based on jingxin's experience of cultivating small base stations for more than 10 years, small base stations really want to bring value to customers, which requires manufacturers to have strong all-round support capacity in research and development, production, landing service and other aspects.


There is no doubt that the 5G cloud station compartment scheme based on the open platform is closer to the indoor vertical industry application scene. The open platform integrating mobile edge cloud with hardware and software decoupling will promote the revolutionary reconstruction of network construction, support and operation chain. Experts have expressed that in the future, the Internet of things business will highly rely on the processing power of edge cloud to realize the requirements of high bandwidth, low latency and large connection, and improve the business performance strongly associated with the scene.
