Sony thinking inside the box for wireless
Register Hardware reports: [edited]
Sony has developed a wireless communications technology designed to replace the cabling within gadgets rather than connections between devices.
The technology operates within the 30-300GHz band. It's called the 'millimetre wave' zone, thanks to a wavelength of 1-10mm, but it's the frequency that matters since it's high enough to permit very high speed data transfer.
Using a 1mm antenna, Sony was able to get a 11Gb/s transmission speed over a distance of 14mm. Better, more directional aerials can be used to get the distance up to 50mm, Sony said.
Why replace wires inside, say, a TV set? Because it means fewer materials are used to produce the device, Sony claimed, and it "enhances the reliability of movable and detachable parts within the product".
In short, it allows companies to make truly modular products whose component parts don't need to be wired together.
