For 5G ultra-high precision time server requirements
Huawei, together with China Mobile, has conducted many in-depth discussions and independently carried out research on a number of key technologies such as satellite dual-frequency reception, ultra-high-precision time-locking algorithms, and ultra-high-precision time distribution.
At the same time, with the assistance of the National Timing Center of the Chinese Academy of Sciences, research on satellite co-viewing technology was carried out and implemented on Huawei SYNLOCK BITS time server products.
Finally, Huawei's self-developed SYNLOCK BITS time server products for the 5G era successfully passed all test items, in which the time synchronization accuracy was improved by 10 times compared to 4G bearer time servers.
For 5G bearer network SPN equipment requirements
Huawei used the PTN 990, an SPN device that supports 5G evolution and has an ultra-high precision clock chip, for testing and verification.
In all metrics, the time and frequency output deviation is within 5ns, which is a 15x improvement in time performance compared to 4G devices.
In particular, the ultra-high-precision time synchronization module effectively resisted noise interference in a simulated existing network plus noise test scenario, fully demonstrating the high-performance and highly reliable qualities of Huawei SPN equipment, which was highly recognized by China Mobile.
From promoting the adoption of the FlexE interface by standards organizations to winning the Outstanding Technology Innovation Award for the X-Haul 5G bearer solution at the International Communications Exhibition, Huawei continues to innovate in the 5G bearer field. The successful passing of this high-precision time synchronization test is another important milestone in the practice of its X-Haul 5G bearer solution. For the future, Huawei will work tirelessly to build a sustainable 5G bearer network and help operators achieve 5G commercialization as soon as possible.
