The controversy over Bluetooth technology's long range future continues with a good deal of the differing opinions focusing on the likelihood that a PHY/MAC for the next-generation, highs-speed Bluetooth is economically viable.
The Bluetooth SIG recently announced its adoption of the WiMedia Alliance's version of wireless USB. The SIG has also announced that it will use the 6-GHz band for its next-generation specification.
That announcements have raised questions in some quarters about power consumption, the cost of developing WiMedia-compliant transceivers, and whether WiMedia's wireless USB actually competes with Bluetooth.
A leading spokesman for this point of view is Jon Adams, Freescale's director of wireless technology strategy. (For details on Adams; perspective, go to
Freescale is promoting an alternative to the WiMedia Alliances wireless USB.
On the other side of the debate, Michael Foley, executive director of the Bluetooth SIG, said expressed confidence in the ability of design engineers to create an economical PHY/MAC chip. He said the SIG expects initial version to be available in early 2008 priced at between $3 and $4the same range that today's Bluetooth chips were in two years ago.
Foley also points out that the SIG is moving ahead with the high-speed version of its spec and that the SIG's core work group, which deals with the Bluetooth radio, should have something ready for testing this summer and that the spec should be ready late this year or early next year.
