Electromagnetic Environment Measurement And Compatibility Analysis Of Mobile Base Station

With the rapid development of radio technology and a large number of radio stations'operation, the radio spectrum resources become increasingly strained, and the radio spectrum pollution incidents have occurred, which seriously endangered the normal order of the air waves. Electromagnetic environment measurement is the effective way to ensure communication quality, to rational plan and layout of the new stations and to avoid radio signal interference. According to electromagnetic compatibility analysis and electromagnetic environment measurement before the radio stations setting up and using, it can avoid unnecessary losses of setting up radio stations ignorantly, and the frequency in different businesses sharing can be achieved, thereby these methods can enhance the effective use of radio spectrum resources, and provide the reasonable scientific basis for the assigned frequencies.The work in this paper can be summarized as follows:The paper discusses and analyzes the electromagnetic environment measurement system and testing radio equipment system. Automatic test system of electromagnetic environment in the management of the radio become more and more mature.And discusses the components and device parameters of the radio stations'electromagnetic environment measurement system. Focus on the use of the electromagnetic spectrum analyzer test environment to get accurate test data, according to different frequencies, different signal types and sizes, how to set reasonable parameters for discussion. On how to choose the right antenna, how to choose the right amplifier, how to choose the right filter for discussion. The paper analyzes evaluation of Measuring Uncertainty in testing radio equipment system. presents the system sensitivity of the calculation methodsThe electromagnetic environment with location of communication base station is measured by using the measurement systems.Compatibility of 3G communication base stations is analyzed, and it may be subject to interference. Anglicizing PHS to 3G base stations compatibility as an example.The WCDMA communication base station and the microwave relay station with the frequency of electromagnetic compatibility is analyzed.
