Sony to unveil in-box wireless technology

Bangalore: Sony claims that it has developed a wireless communications technology designed to replace the cabling within gadgets. The technology called the 'millimetre wave' zone, operates within the 30-300GHz band. It has a wavelength of 1-10mm and a very high frequency that allows very high speed data transfer, reports Tony Smith of The Register.

This technology would mean a smaller antennae but the range is limited. Using a 1mm antenna, Sony was able to get a 11Gb/s transmission speed over a distance of just 14mm. The effort used 70mW of power. Better, more directional aerials can be used to get the distance up to 50mm, Sony said.

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

This technology can revolutionize the amount of things required to send across a signal. 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 operates at up to 560Mb/s. It will be released under the TransferJet brand.
