Atheros and Wilocity developing 60GHz wireless PCIe

Posted on Wednesday, July 14 2010 @ 21:20:07 CEST by

Atheros and Wilocity announced they're working on a 60GHz wireless technology to be used for ultra-high-speed networking and wireless PCI Express.
These devices should start sampling next year, and based what Wilocity told us, they'll allow notebooks to connect to displays, storage devices, and even auxiliary graphics processors, all wirelessly. The same 60GHz wireless adapters will support 2.5GHz and 5GHz bands, as well, so they'll let you connect to existing Wi-Fi networks.
The bandwidth of wPCIe is expected to be about the equivalent to two lanes of first-gen PCIe.
Wilocity told us that wPCIe can push bits at up to 5Gbps (625MB/s), and that the spec should move "quickly" to 7Gbps (875MB/s). Assuming that doesn't account for the 8b/10b encoding used by PCI Express, you can expect PCIe transfer rates of up to 500MB/s at first, which is equivalent to two lanes of first-gen PCI Express connectivity. That's probably not enough for a proper graphics card, but as we found while reviewing Zotac's Zbox HD-ID11 nettop, an Nvidia Ion GPU hooked up over a single gen-one lane can still crank out decent frame rates in casual games at 1080p.
