The Sony Corporation
today, Monday, presented wireless data transfer technology for use within electronic products such as televisions. The solution is based on millimetre waves for broadband transfer and should this make complex internal wiring obsolete. This promises more compact, better priced and more reliable devices.
Sony’s wireless technology uses millimetre waves for transfer. With frequencies of 30 to 300 gigahertz, these are not only suitable for very high data rates, but also manage with very small aerials, according to the company. Thus, transfers internally within the device are possible at several gigabits per second (Gbps), which would mean clear advantages as compared with a wired solution, according to Sony.
For higher and higher data rates, an increasing number of circuits are needed in wireless transfer, which makes complicated, larger integrated circuits and complex printed conductor boards necessary according to Sony. The new technology promises to reduce the number of circuits needed and thereby make the electronic components simpler. At the same time, the reliability of moving and removable parts on the end product increases through the contract-free transfer.

Sony has integrated a transmitter and receiver on a 40-Nanometer CMOS chip with a surface area of just 0.13 square millimetres. This makes it possible to achieve a transfer rate of eleven Gbps across a surface of 14 millimetres (mm) when one-millimetre aerials are used, according to the company. Here, the power consumption is 70 milliwatts according to the company. With suitable directional antennae, the transmission range could be increased to 50 mm.
The technology is being presented in the context of the International Solid-State Circuits Conference
specialist event. According to Sony, the company aims to use it for a range of electronics products. The company has not yet provided information on how long it will be before devices with internal wireless transfer come to the market.
