In conventional usage environments, the installation and debugging of full band signal blockers are relatively simple. Generally, all that is required is to power on the device and switch on the main switch. By observing the working status of the mobile phone at different distances from the blocking device, the effectiveness of the blocker can be easily determined. However, in complex usage environments where signal analysis or adjustment plans need to be formulated, the use of a spectrum analyzer becomes necessary. This also highlights the importance of a spectrum analyzer in the installation of signal blockers.
Complex Usage Environments:
Complex usage environments can be broadly categorized into two types. Firstly, in on-site environments, the base station signals transmitted from mobile phone base stations vary in format and have significant differences in signal strength. This can result in the full band signal blocker being effective in blocking signals from some mobile phones, while seemingly having no effect on others. In such cases, having a spectrum analyzer on-site allows technical personnel to quickly determine the stronger base station signal format or analyze and identify the signal suppression that is not fully achieved in certain mobile phone frequency bands. Thus, the importance of a spectrum analyzer in the installation of signal blockers is evident.
Benefits of Spectrum Analyzer:
With a spectrum analyzer on-site, technical personnel can use signal retrieval to quickly identify the stronger base station signal format or analyze and identify the signal suppression that is not fully achieved in certain mobile phone frequency bands. By receiving the blocked signals through an antenna and displaying them on the spectrum analyzer, the waveform amplitudes on various frequency bands can be observed, or the signal strength values can be read. This allows for an accurate understanding of the signal coverage strength of the blocked signals in different areas. Consequently, by adjusting the installation position of the full band signal blocker or the direction of the antenna, the desired signal blocking effect can be achieved in the corresponding areas.
In conclusion, the installation of full band signal blockers in complex usage environments requires the assistance of a spectrum analyzer. The spectrum analyzer enables technical personnel to analyze and identify the strength of base station signals and the effectiveness of signal suppression in different mobile phone frequency bands. By utilizing the information obtained from the spectrum analyzer, adjustments can be made to the installation position of the signal blocker or the direction of the antenna, ensuring the desired signal blocking effect in specific areas. Therefore, the use of a spectrum analyzer is crucial in achieving optimal performance from signal blockers.
