Metalink announces sampling of its one-chip MIMO RF solution: The company says that it can pack everything that 802.11n will require into this single chip for RF. Of course, this is a little early to say that anything in 802.11n can wind up in silicon. I’ve spoken to a number of chipmakers, and none of them will finalize silicon until the specification is much further along. The latest IEEE meeting on 802.11n resulted in a step backwards from a draft proposal. Metalink says they’re sampling today, shipping in third quarter.
The TGn Sync proposal doesn’t achieve supermajority for 802.11n: Although the proposal won more than 50 percent of the vote at the last IEEE 802.11n task group meeting, it failed to achieve the supermajority needed to move ahead this time around. That means that the floor is back open to reconsider other proposals, with WWiSE being the only reasonable contender. It’s likely that compromise will now be achieved because while there are a few basic differences in encoding that must be resolving, much of the concern is over optional versus mandatory modes and configurations.
I review NetGear’s RangeMax MIMO device at Mobile Pipeline: I found its range extraordinary and worth the price. It sits in a middle ground in cost and feature claims between the Airgo-based Linksys, Belkin, and Buffalo gear and plain old 802.11g.
It calls itself MIMO, and I can’t really say that it meets the spec in that MIMO requires spatial multiplexing. Or so the inventors of MIMO—founders of Airgo—would say. (Nanotech used to mean little machines but now means anything small, too.)
Jungo will produce reference designs ready to go for Airgo’s MIMO chips: Reference designs are licensed by manufacturers who add their own case designs and customization to the software featureset and then have them manufactured on demand. This is typically how most major Wi-Fi and Ethernet equipment comes to market. A relatively small percentage is developed in house.
Jungo uses embedded Linux and provides an essentially turnkey system for manufacturers who may add a little secret sauce in the form of a custom configuration wizard and extensions to integrate with other products in their network family. The OEM (original equipment manufacturer) as the retail brands are known in this case handle inventory, sales channels, outsource production, and technical support.
