Communication system capacity test equipment, cabinet and system

Abstract

The embodiment of the invention provides a communication system capacity test device, a cabinet and a system. The communication system capacity test device comprises a printed circuit board (PCB), a front panel, a rear panel and a plurality of power dividers; as a plurality of terminal interfaces are arranged on the PCB, a plurality of terminal modules can be accessed, a real terminal can be simulated, and the capacity test of a communication system is realized. The equipment can be applied to an LTE-G 230MHz system of a power private network, and fills the blank of capacity testing equipment of the LTE-G 230MHz system in the prior art; performance testing of other devices in the communication system and testing of other indexes of the system can be realized by connecting a radio frequency output interface on the front panel with an external device. According to the invention, serial ports of a plurality of terminal modules can be converged and then output through a plurality of power dividers, so that serial port wiring is simplified, the problem of complexity of independent wiring of the serial ports is solved, the system building complexity can be greatly reduced, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of communication system capacity testing, and more specifically, to communication system capacity testing equipment, a cabinet and a system. Background technique [0002] At present, the capacity test of the Long Term Evolution (LTE) system generally adopts a standard comprehensive tester, such as TM500, which can realize the test of simulating a large number of terminals. With the continuous application and promotion of communication technology in private networks, there is an urgent need for capacity testing of private network systems. [0003] In the LTE-G 230MHz system of the power private network, due to the existence of a large number of terminals, a large number of terminals is required to be carried by a single cell. However, the industry chain related to the LTE-G 230MHz system is not yet mature, and the corresponding test instruments are not yet perfect. For a capacity test device for LTE-G 230MHz...

Problems solved by technology

[0003] In the LTE-G 230MHz system of the power private network, due to the existence of a large number of terminals, a large number of terminals is required to be carried by a single cell. However, the industry chain related to the LTE-G 230MHz system is not yet mature, and the corresponding test instruments are not yet perfect. A capacity test equipment for LTE-G 230MHz system, if the capacity test of a large number of real terminals is carried out, not only the workload is huge, but also the labor cost, time cost and capital cost are very high, and it is basically not operable

In addition, with the further development of research and development, even if a multi-terminal simulator for LTE-G 230MHz system is subsequently developed, it is difficult to simulate the real wireless scene, and it is impossible to verify the end-to-end communication of multiple terminals by connecting several real terminals to each PC. Terminal business, it is difficult to meet the development test, performance test, network access test, field test and other work of the industry chain manufacturers
