Fujitsu 5G 10Gbps Panel
Fujitsu unveils 10Gbps single-panel 5G antenna that can provide 2.5Gbps speeds to four different users simultaneously

Fujitsu Laboratories has recently unveiled a single-panel antenna that enables multiple 5G connections on a small, energy-efficient base station. It provides speeds of at least 10Gbps across four simultaneous 2.5Gbps signals.
"Conventional 5G system structures require use of an antenna panel for each terminal when simultaneously transmitting to multiple terminals. Now, by controlling with high accuracy the phase (angle) of signals separately emitted from 128 antenna elements, Fujitsu Laboratories has suppressed the interference between signals," the company explained.
"Currently, to avoid radio wave interference during communications with multiple users at once, base stations have been configured to use a number of antenna panels corresponding to the number of concurrent users. To miniaturise the equipment so that it can be deployed anywhere, the best option is to provide multi-directional transmissions from a single antenna panel."
"The company also uses circuitry that detects the differences in phase between phased array chips, which enables highly accurate phase control for any size antenna panel that has between 64 and 256 antenna elements," it said.
"As a result, by holding the difference in undesired emissions intruding between one radio wave communicating with a device and another radio wave with another device to 20dB or more, it makes it possible for a single antenna panel to carry out high-capacity communications of 10Gbps or more."
