"In the 5G era, indoor coverage is more important, and the status of small base stations has therefore become more prominent." Ding Haiyu, director of the Wireless Institute of China Mobile Research Institute, said at the industry's first commercial 5G cloud small station technology salon at MWC19 Shanghai. He believes that there are currently three main solutions for the construction of room divisions: the old traditional room division scheme is preferred for pure coverage scenarios, the cloud small station solution (extended leather base station) is preferred for experience scenarios, and the distributed leather base station is preferred for super-capacity scenarios. Program.
It is reported that as early as 2017, China Mobile Research Institute began a 5G small stand project, researching a lower cost indoor distribution coverage solution based on an extended leather base station. Jingxin Communications has been deeply involved in the field of wireless optimization for more than 20 years, and currently ranks first in the domestic market for network optimization, expanded leather base stations and integrated small base stations. According to Luo Manjiang, general manager of Jingxin Communication Network Products Division, the company has worked closely with China Mobile Research Institute to establish a complete 5G signal source, 5G spectrum analyzer, 5G terminal simulator and other supporting instrument development tool resources. With the strong support of China Mobile Research Institute and Intel, Firstcall was opened at the end of 2018. This year, the IoT, laboratory and field tests have been completed, and it has reached the commercial level.
There is a large amount of demand for 5G from vertical industries, which requires small base station manufacturers to deeply integrate with the industry. Ding Haiyu predicts that “in the future, the 5G small base station market may be part of the indoor market, and the other part of the industry market, that is, small base station manufacturers will be dispersed in different industry applications, rather than a set of systems to dominate the world. Who is deeply integrated with the industry, Whoever will win."
5G is not only a new generation of technology, but also the DNA and cornerstone of the future innovation platform. Zhang Xiaowen, chief engineer of Intel’s wireless software, said that the x86 small cell chip solution is a network system chip specifically for 5G wireless access and edge computing. It will introduce Intel’s computing architecture into wireless access base stations and allow more computing functions on the network. Distribute at the edge. The 4G small base station is based on a general SoC chip. Compared with the 5G "cloud" small station, the performance is greatly improved, the platform is more open, and it can provide more flexible value-added service capabilities. The key design includes the following elements: scenario-based functions and performance requirements, platform openness, IT-based system architecture, and intelligent management platform. Luo Manjiang believes: “In the 5G era, signal coverage has been transformed into capacity demand coverage. 5G small base stations will inevitably increase explosively, but the demand will be gradually released. Based on the experience of Jingxin working on small base stations for more than ten years, small base stations For base stations to truly bring value to customers, manufacturers must have sufficiently strong all-round support capabilities in R&D, production, and landing services."
There is no doubt that the 5G cloud small station room sub-solution based on the open platform is closer to the indoor vertical industry application scenarios, and the open platform with decoupling of software and hardware integrates the mobile edge cloud, which will promote the revolutionary importance of the network construction, support, and operation chain. Structure. Experts have said that in the future, IoT services will rely heavily on the processing capabilities of the edge cloud to achieve high bandwidth, low latency, and large connection requirements, and to improve the performance of services that are strongly related to the scene.
