Domestic RF synchronization test instrument market has considerable prospects

Foreword: The technology of time-frequency synchronization test has high technical requirements. This field has been controlled by European, American and Japanese manufacturers for a long time. Domestic companies basically do not have vendors involved in this test.

At present, China Mobile has launched a large-scale deployment of PTN. While implementing base station services, it also tries to use IEEE1588 to replace GPS to achieve time synchronization. Compared with the GPS timing mechanism, IEEE1588 has obvious advantages in network security, cost control, and network operation and maintenance.

IEEE1588 also has some shortcomings, such as optical path asymmetry, which brings certain errors to time transmission, which leads to a decrease in time synchronization accuracy. The decrease in time-frequency synchronization accuracy makes it impossible to guarantee the QoS of the network. Such errors need to be measured and added. make up. Therefore, only the time-frequency test can ensure the normal operation of the entire system.

The technology of time-frequency synchronization test has high requirements. This field has been controlled by European, American and Japanese manufacturers for a long time. Domestic companies basically have no manufacturers involved in this test.

Although international manufacturers almost monopolized the time-frequency synchronization test market, with the large-scale deployment of PTN, Xia Guang Company found through investigation that only about 6 international well-known brand test instrument manufacturers launched IEEE 1588 time-frequency synchronization test products, but There is no IEEE 1588 time-frequency synchronization test instrument that is actually suitable for Chinese operators to use in engineering maintenance.

The product design of foreign manufacturers is more focused on laboratory environments, R&D of PTN equipment, protocol analysis, network monitoring, and other applications, but it can not effectively meet the actual site engineering and maintenance needs.

For example, foreign manufacturers related instruments do not have portable products, there is no good man-machine interface, there is no menu display in Chinese culture, from a functional perspective, emphasis on simulation, monitoring and protocol analysis, inconvenient for asymmetry testing Wait. This in fact caused a serious absence of IEEE 1588 engineering maintenance instrumentation on a global scale. This will seriously impede the scale deployment of the IEEE 1588v2 synchronization technology in the PTN network, and also laid a hidden danger for routine maintenance and troubleshooting. Therefore, how to effectively solve the problem of PTN synchronous testing in engineering and maintenance has become a difficult problem for many manufacturers to overcome.

Although foreign products are advanced, they have a certain gap with China's market demand. Only products that meet market demands are good products. Domestic testing companies should seize the market opportunities and create suitable products according to their needs in order to achieve good development.
