Fujitsu announces its 10Gbps 5G Antenna
Fujitsu Laboratories recently launched its single panel antenna which has been designed to allow multi 5G connections on a small and energy-proficient station. According to Fujitsu, this antenna solution has the capacity to provide up to 2.5Gbps speeds simultaneously to four different users through a single panel. The company also mentioned that it could be utilized across stadiums and train stations. Using mmWave (millimeter-wave) 28GHz 5G spectrum band and uses 128 antenna elements as well as 16-phased array chips which fit into a one 13cm square circuit board.
According to the company, the conventional 5G system structures need antenna panel for individual terminal when transmitting to different terminals simultaneously. However, simply by managing the phase of signals that separately emit from the 128 antenna elements, with high precision, Fujitsu Laboratories has been able to significantly subdue the interference between the signals.
The company elaborated stating that the company has ensured that base stations are configured to utilize a number of antenna panels that correspond to the number of simultaneous users. This is to prevent radio wave interference in the course of communications with concurrent multiple users. The company mentioned that in order to miniaturize the equipment to allow for deployment anywhere, the perfect option is to offer multiple directional transmissions from one antenna panel.
To attain this, Fujitsu said it has created a phased array chip which has the capacity to control the phase of signal broadcasted with precision of one degree or lower from antenna element. In addition to this, the company mentioned that it utilizes circuitry that spots the variance in phase between different phased array chips. This allows highly precise phase control for every size of antenna panel that uses between 64 and 265 antenna elements. The company mentioned that it plans to commercialize this technology by 2021.
This statement comes at the wake of the signing of a 5G partnership with Ericsson sometimes last month. The company disclosed that it plans to combine the core network portfolios and the radio access to provide 5G mobile network services and solutions all over Japan. According to Fujitsu, the research and development strength of Ericsson and Fujitsu will ensure the best direction to bring global 5G solutions to Japan, while exploring the wider global market. The EVP and head of Network Business Group of Fujitsu, Tango Matsumoto, said that Fujitsu will offer open and standard ‘flexible 5G network systems’ with the use of wireless technology expertise.
It is imperative to mention that Fujitsu has started a field trial of its 5G ultra high density distribution antenna technology this past year and has also conducted tests of simultaneous high speed transmission of high resolution video utilizing antenna system. This was done in collaboration with NTT DoCoMo, a Japanese carrier. Fujitsu and Fujitsu Laboratories have been working with NTT DoCoMo on 5G trials since the year 2014 and have also partnered with the carrier to evaluate the speed of communications for distributed antennas implemented at various outdoor locations.
Early November, Fujitsu has also mentioned that it is actively working on creating facial and palm vein data authentication technology, featuring the capabilities of integrated biometric identification. This is in support of a cashless society.
