Sony developed ‘world’s first’ in-box wireless tech

Sony has developed a wireless communications technology which is designed to replace the cabling within gadgets rather than connections between devices.

The new technology operates within the 30-300GHz band. It’s called the “millimetre wave” zone, but it’s the frequency that matters since it’s high enough to permit very high speed data transfer. The small wavelength means the antennae can be tiny, which is perfect, in short for in-box communications, Sony reckons.

But keep in mind the range is limited. Sony was able to get a 11Gb/s transmission speed over a distance of just 14mm, by using a 1mm antenna . The effort use a 70mW of power. Sony said “more directional aerials can be used to get the distance up to 50mm.”

Sony will be showing it off at International Solid State Circuits Conference (ISCC) in San Francisco this week .Sony has built a 40nm, 13mm² test chip containing transmitter, receiver and antennae to demonstrate the technology.

Why should we replace wires inside a TV set? Because it means few materials are used to produce the device, Sony claimed “enhances the reliability of movable and detachable parts within the product”. In short words, it allows companies to make truly modular products whose component parts don’t need to be wired together.

Sony is already gearing up to release device-to-device near-field data transfer kit that could operates at up to 560Mb/s. Avd it will be released under the TransferJet brand.
