Communication system capacity testing equipment, cabinets and systems

Abstract

Embodiments of the present invention provide a communication system capacity testing device, a cabinet, and a system. The communication system capacity testing device includes a printed circuit board (PCB), a front panel, a rear panel, and a plurality of power dividers. Since the PCB is provided with a plurality of terminal interfaces , can access multiple terminal modules, simulate real terminals, and realize the capacity test of the communication system, which can be applied to the LTE-G 230MHz system of the power private network, making up for the blank of the capacity test equipment of the LTE-G 230MHz system in the prior art; It can be connected to external devices through the RF output interface on the front panel to realize the performance test of other devices in the communication system and other indicators of the system; multiple power dividers can be used to aggregate the serial ports of multiple terminal modules and output them. Simplifying the serial port wiring and solving the complexity of the serial port wiring alone can greatly reduce the complexity of system construction and save costs.

Description

technical field [0001] The present invention relates to the technical field of communication system capacity testing, and more particularly, to communication system capacity testing equipment, a cabinet and a system. Background technique [0002] At present, the capacity test of the Long Term Evolution (Long Term Evolution, LTE) system generally adopts a standard comprehensive tester, such as a 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 also an urgent need for capacity testing of private network systems. [0003] In the LTE-G 230MHz system of the private power network, due to the existence of a large number of terminals, a large number of terminals are required to be carried by a single cell, but the industry chain related to the LTE-G 230MHz system is not yet mature, and the corresponding test instruments are not perfect. A capacity test...

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
