Wireless network channel simulator as well as system and method for testing wireless network equipment

Abstract

The invention provides a wireless network channel simulator which comprises a control background and a wireless network channel simulation module, wherein the control background is used for generating a wireless network channel script; and the wireless network channel simulation module is used for dynamically simulating an overhead wireless network channel and then simulating an actual wireless network environment under the control of the wireless network channel script. The invention also provides a system and a method for testing wireless network equipment. By using the wireless network channel simulator as well as system and method for testing the wireless network equipment provided by the invention, a system testing environment built in a laboratory can support PTM (point to multipoint) and MTP (multipoint to point) wireless network channel simulation capabilities, and the time for enabling base station systems or terminal products to appear on the market in batches are shortened.

Description

technical field [0001] The invention relates to the technical field of wireless cellular communication, in particular to a wireless network channel simulation device, a wireless network equipment testing system and a method. Background technique [0002] A wireless channel is an image metaphor for the path between the sending end and the receiving end in wireless communication. [0003] The propagation of radio waves in a wireless channel is not a single path, but a synthesis of many reflected waves from many paths. Since the distances of radio waves passing through each path are different, the arrival time of reflected waves from each path is different, that is, the time delay of each signal is different. When the transmitter sends a very narrow pulse signal, the signal received by the mobile station is composed of many pulses with different delays, which is called delay spread. [0004] Due to the mobility of the mobile station in mobile communication, as mentioned above...

AI Technical Summary

Problems solved by technology

It is precisely because the laboratory system test cannot describe the channel characteristics in the actual wireless network environment. Usually, before the base station system or terminal is commercialized in batches, it is necessary to build a certain scale of commercial experimental bureaus to fully expose the problems existing in the base station system or terminal.

Large-scale commercial experiment bureaus require huge investment, and require a long time for construction and opening, so it becomes a luxury before the mass launch of base station systems or terminal products
