"WIRELESS: Motorola prototype validates metal-oxide for WPAN device"

Wireless personal area networking (WPAN) got another boost today, when Motorola Labs (Tempe, Ariz.) announced that its joint-development agreement with Phiar Corp. (Boulder, Colo.) had succeeded in validating metal-insulator electronics as a viable alternative to semiconductors for millimeter wavelength 60-GHz WPAN devices. IBM recently announced a deal with Taiwan's MediaTek to supply chip sets for the IEEE 802.15.3c WPAN standard using IBM's silicon germanium (SiGe) BiCMOS radios. Motorola claims to be developing a rival 60-GHz radio sans semiconductors.
