Method and device for evaluating and testing communication efficiency of ultrashort wave wireless communication equipment

Abstract

The invention discloses a device and method for evaluating and testing communication efficiency of ultrashort wave wireless communication equipment. According to the method, the tested equipment is limited in a working frequency band, and a radiation spacing is not smaller than 20 wavelengths; working frequency points cover high, intermediate and low ends of the working frequency band of the tested equipment; when the tested equipment works in a frequency hopping mode, a working frequency hopping table selected by testing personnel should include a full-frequency-band frequency hopping table and fractional-frequency-band frequency hopping tables, wherein the fractional-frequency-band frequency hopping tables are selected at high, intermediate and low sections of the working frequency band of the tested equipment; after receiving a signal radiated by a transmitting party, an antenna of a receiving party enters an electromagnetic environment simulation device and selects various types of electromagnetic fields by a natural electromagnetic environment unit and a threatening electromagnetic environment unit; and communication efficiency is evaluated. The device and method disclosed by the invention can provide various types of testing environments under different transceiving spacing, geography, weather and background electromagnetic environment conditions, solve the difficult problem of difficulty in testing and evaluation under corresponding conditions on site, and have the characteristics of low cost, time saving, easiness for operation and simplicity and convenience for implementation.

Description

technical field [0001] The invention relates to the technical field of wireless communication capability testing, in particular to a device and method for evaluating and testing the communication performance of ultrashort wave wireless communication equipment. Background technique [0002] At present, the common method for evaluating and testing the communication performance of ultrashort wave wireless communication equipment is to conduct pull-distance tests outdoors under conditions such as various geographical environments, climate environments, transmission distances, and natural electromagnetic radiation backgrounds. Among them, different geographical environments should reflect different terrains (plateaus, plains, mountains, etc.), ground cover (cities, suburbs, villages, vegetation, etc.), and different climate environments should reflect different meteorological conditions (such as temperature, Weather characteristics, etc.), different natural electromagnetic radiat...

AI Technical Summary

Problems solved by technology

There are at least two disadvantages to achieve the above conditions: first, it is difficult to meet the various environmental conditions of the assessment, mainly in the difficulty of finding and exhaustive test sites for various geographical environments, and the random occurrence of various extreme weather conditions. The nature and periodicity are long, and various dynamic changes of the natural electromagnetic radiation background are not easy to control, etc.; the second is that it takes a lot of manpower and material resources to meet such test conditions, and the test cycle time is long and the cost is high.

Therefore, in actual operation, it is usually just sampling patterns, and it is impossible to test through various environmental conditions. Such test results have low reliability, which cannot satisfy and is not enough to support the scientific and effective evaluation of the tested equipment.
