Ruckus Pushes Video with Diversity

By Glenn Fleishman

Video54’s now Ruckus Wireless and is focusing on video: The company creates overlay chips and antennas that allow beamforming with spatial diversity—not exactly the spatial multiplexing of Airgo’s MIMO, but it still packs a bunch, as seen in the NetGear hardware that incorporates its first-generation technology overlayed on an Atheros chipset.

Ruckus will focus on video and has built quality-of-service (QoS) prioritization into its systems so that spatial paths can be blended with QoS to give video streams and signal paths greater priority for clearer signals. Their method is not identical to the still-in-progress 802.11e—it may be ratified this month—which has had bits and pieces turn into software and firmware in shipping products. QoS is supposed to allow different kinds of data to have different priority on the same network to keep voice, video, and data flowing without glitches.

I’ll be curious how this plays out in heterogeneous networks with many kinds of 802.11a/b/g and proprietary extension adapters using Ruckus Wireless gateways. The company can offer certain kinds of efficiencies at the hub, but as with a lot of this newer multipath technology, equipping all computers and systems with the same technology produces the optimum results.

The company seems to be expecting its technology to be hook into home-entertainment components, allowing a digital video recorder to stream its video to a remote display, among other tasks.

Its first hardware products, a gateway and an adapter, have retail prices of $169 and $129, respectively.
