Consequently, these new compact SAW filters were developed to improve usability in order to assure stable communications through the prevention of radio wave interference with other systems in adjacent signals during data transmissions and data communications in next-generation high-speed wireless networks.
By using beamforming, the system suppresses radio wave interference from unwanted directions, and prevents deterioration of speed even when many users are transmitting data simultaneously.
Until now, when one femtocell was near either another femtocell or an outdoor macrocell base station, radio wave interference would distort communication signals.
Fujitsu developed technology that enables the femtocell to detect its surroundings and automatically adjust the timing, transmission power, and transmission frequency band of its communications to reduce all three types of radio wave interference.
