A few days ago, the simulation network laboratory of vivo communication center was completed at vivo's global headquarters. The simulation network laboratory of vivo communication center is planned to be built in three phases. The first phase of the laboratory put into use this time and built by the China Academy of Information and Communications Technology alone has nearly 100 sets of world-leading equipment, with an investment of tens of millions of yuan.

Vivo Communication Center Analog Network Laboratory deploys the same type of base station and core network used by operators on a large scale in the laboratory, and can flexibly adjust the signal, build a combination of frequency bands in different regions, and simulate the commercial 5G/4G network configuration of the world's mainstream operators, engineers can accurately complete a large number of functional verifications that previously needed to be carried out outdoors and in the field in the laboratory.
Weak coverage, high-speed movement, high density and other extreme scenarios that test the performance of mobile phones can also be verified and tuned in the laboratory to ensure the strong performance of mobile phone communication performance.

In the laboratory, engineers not only pay attention to various signal environments in consumers' daily lives, but also simulate rich and diverse business scenarios such as games, videos, and live broadcasts, complete end-to-end system verification solutions, provide strong support for product optimization through intelligent data collection and analysis, and continuously improve the ultimate experience of users in the communication process.

The simulation network laboratory will provide vivo global R&D engineers with multi-dimensional communication testing capabilities from the underlying communication protocol to the upper layer user experience, for example, build a time model to evaluate the actual battery life performance of mobile phones in different network environments and different use scenarios and optimize them; continue to follow up the upgrade iteration of future communication technology, and lay out the new features and new features introduced by the 5G next-generation standard Relay16 in advance, bringing consumers the most cutting-edge new technology experience.
Rigorous 4000+ hours test "quenching" high-end quality
The simulation network lab will be based on user experience to ensure that the vivo mobile phone used by consumers can be at ease in the face of the intricate actual network environment. In the research and development cycle of each vivo product, hundreds of engineering mobile phones have entered the simulation network laboratory of the vivo communication center to carry out "quenching" to ensure that the mass-produced mobile phones have the strongest signal transmission and data upload and download capabilities when they reach the hands of users, and have the best power consumption and the most stable performance.

For example, in order to ensure the reliability and performance stability of the vivo mobile phone system obtained by consumers, in the vivo communication center simulation network laboratory, a large-scale communication stability test environment has been built, and each mobile phone must go through 4000+ hours of continuous continuous power stress testing, answering and dialing more than 10,000 calls and more than 1,000 hours of data download and upload testing, in order to successfully "get out of customs".

Liu Jingcai, general manager of vivo's testing technology and word-of-mouth control field, said: "Vivo has always been guided by user needs, focusing on imagery, design, system, performance and long track, creating the ultimate product and service experience for users. The construction of the vivo communication center simulation network laboratory is to adhere to the long-term doctrine, continue to invest in the long performance track, and continue to invest in places where consumers cannot see, so as to provide users with the best communication experience. In the future, vivo's investment in the underlying technology will be further upgraded. ”
