Is 60 GHz technology in danger from an industry clash? Should the two 60 GHz efforts--WirelessHD/IEEE 802.15.3c and Wireless Gigabit Alliance/IEEE802.11ad--get together?

I don't understand the logic behind the zero-royalty issue and I am a little surprised by the crude comment about the market of zero units.

Virtually all WiMedia members and companies with an IP position in UWB are also Bluetooth members, and as such they have agreed to zero royalty in the Bluetooth SIG. This sounds like someone in the SIG is confused or uses the issue as an excuse.

The same IP issue will apply to any 60GHz standards, because Ecma, IEEE and virtually all other organizations are not royalty free, because most companies, including Bluetooth Board members, haven't joined zero royalty based industry alliances in recently.

While I don't know if it's true that "virtually all" agreed as Roberto claims, I agree with him that it seems to naive (if not disingenious) to expect anything better for 60GHz. Even assuming that they did somehow manage to bypass royalties for 60GHz Bluetooth by mircle, surely most chips supporting that protocol will actually be multi-standard, and so the chips themselves might not escape royalty payments no matter what the Bluetooth SIG does.

One of the 60 GHz solutions (SiBeam) calls for a RF output of 10 Watts for a PAN! Is that the Bluetooth's SIG's idea of low power? 60 GHz on battery operated device?

The IP and power issues are very real. But the overarching question for me is whether 60 GHz is following, in part, the same path that led ultrawideband into trouble.
