Sony Prototype Uses Wireless Signal to Reduce Wiring Within Devices no comments

This has nothing to do with ereaders per se, but it is quite interesting for gadgets in general.
Tech-On reports that Sony has prototyped a system for transmitting signals between chips within a device using a wireless signal rather than with conventional hard wiring. The system uses radio waves in the 60GHZ millimeter waveband.
Transmitting signals wirelessly between chips rather than over wires has several advantages:
- Chips can be made smaller: less terminals for connections.
- More design freedom: chip placement on a circuit board less restricted by interconnective wiring; chips can be arrayed in three dimensions rather than just on flat boards.
- Should result in lower manufacturing costs.
Since the wireless signal is localized within the device there probably would not be frequency restrictions, etc.
This is probably not a good thing for copper futures prices.
