dual-band products (you know, those that support both 2.4GHz and 5GHz bands) is slowly growing, but already a pair of companies are thinking about the next big thing: tri-band. Atheros and Wilocity have both been eying that 60GHz stuff that the WiGig Alliance is pushing around these days, and now they're announcing a collaboration to "build tri-band wireless solutions that combine the ubiquity and coverage of WiFi with the multi-gigabit performance of the Wireless Gigabit Alliance's 60GHz technology." The new gear would enable all sorts of backwards compatibility, and while there aren't too many details being shared just yet on exactly what kind of kit is in the pipeline, we do know of one particular tidbit. That tidbit, of course, is wireless PCI Express, or wPCIe. Developed by Wilocity, this black magic would essentially enable PCIe devices to be docked outside of the desktop and have their signals beamed to a receiver card within the desktop. Think external graphics, storage arrays, etc., all sans cabling. It's being reported that wPCIe can push data at up to 5Gbps, and if all goes to plan, the spec should scale easily to 7Gbps. Be sure to give the links below a visit for a deeper dive, and get ready to give that SFF machine you've often overlooked... well, another look.
