Sony develops millimeter-wave wireless intra-connection technology

Sony announced the development of millimeter-wave wireless intra-connection technology today, according to a press release on Sony's site. The technology allows high speed wireless data transfer inside electronic devices. The way the system is works is by replacing internal wires and circuitry with wireless connections, thus reducing the size of components and overall cost. Sony claims the new wireless technology will increase reliability, since there is no contact during the transfer of data.

Electromagnetic waves, ranging in frequency from 30GHz to 300GHz, are utilized to obtain ultra high speed data transfer. The press release notes "Sony has integrated highly energy efficient millimeter-wave circuits on 40nm-CMOS-LSIs (with an active footprint of just 0.13mm2 including both the transmitter and receiver), to realize high speed, 11Gbps data transfer over a distance of 14mm using antennas approximately 1mm in size." Because of the small footprint, the circuits can be placed on one chip at a low cost.

Sony's new injection lock system allows for synchronized detection over small circuits, eliminating the Phase Locked Loop, which has been used for synchronization in the past. The updated technology lowers power consumption, while maintaining an adequate transmission range.

No specific date has been announced regarding when products will adopt the new technology.

Just switch to optical instead of stupid ****ing wireless.

Optical interconnects are the future not this crap.

This could provide useful. One thing that comes to mind: wireless transmission of video data in laptops. I come across a lot of laptops with broken LCD cables due to excessive opening and closing of the top cover. If they could somehow replace that cable with this technology, that would certainly improve things. As an example of course, it could apply to any device with moving parts and cables involved.

Being the forever pessimist, this sounds like more to go wrong to me...

I can't help but agree:

a. They are fixing a fairly minor 'problem'

b. Presumably this could interfere/get interfered with, unless you shield the whole case

c. This is Sony making a proprietry format of sorts, see Betamax, LaserDiscs, Mini-disk, UMDs e.t.c.

On the plus side, no wires to get crushed/worn/sheared/freyed, though if you break the antenna or transmitter/receiver, your screwed.

And yeah, hacking stuff would be made easier if you only had to wave a bit of wire near it instead of trying to solder or poke a tiny surface mount contact!

this technology would run rampant over DRM and hacking devices if it was in easily portable things. all it took to crack DVD drm was catch the key in memory by software means imagine if just need a small receiver to tap into the wireless connections then catch all vital information passing or even better injecting code or actions into it. Unless they cover it with some mean protection this will be a big problem

Interesting if true. However, I wonder how it handles scaling. Imagine using this in a PC. That'd be a lot of wireless connections.

Could someone explain this a little for me... I got lost after Sony

Simple lets say a computer between cpu and ram we have bus which is hard wire connected on the motherboard. What this technology does is rather then relying on those physical connections creates a small wireless AP between the 2 connections and transfers the data over small wireless connections.

Electronics jammers may stop your equipment from working in modern warfare/terrorism?

Mw2 comes to life with us soldiers in real life getting ability to run round with EM jammers so people can't see us on their minimap.

(Sony) We can sent 11gbps wirelessly over 14mm! (little under 1.5cm, and somewhere near a half inch).
(me) And you can send WIRED data how fast over copper in that distance?
Something tells me there is more copper in the antenna than is saved in that half inch.

You don't understand. Copper=parasitics which is a pain, Wireless=No parasitics but will have a problem with signal to noise ratio which can be "adjusted." This will allow better component arrangements on the pcb so you will have a fewer layers which translates into smaller PCB footprint. Then translates into a smaller/thinner consumer gadgets.
