[Case Study] 5G Mobile Communication Base Station

Attenuators, couplers, and splitters for adjusting the output level of 5G base stations! We will introduce examples of their implementation in mobile phone base station equipment!

In mobile phone base stations, various methods are used to establish the necessary communication areas depending on the installation location. For outdoor area base stations, small low-power units and large high-power base stations are utilized according to the coverage range of the communication area in urban, suburban, and mountainous regions. Additionally, for indoor area base stations, indoor antenna sharing systems are used to cover areas where radio waves are difficult to reach, such as each floor of high-rise buildings, subways, and underground shopping streets. At Tamagawa Electronics, we provide components for 5G base stations, including coaxial attenuators for adjusting mobile phone signal levels and combiners and splitters for branching antennas, available in both outdoor and indoor types according to the installation area. *For more details, please refer to the related links or feel free to contact us.*
