True G Drops Price, Antenna

By Glenn Fleishman

Airgo’s True G gear will be less than $100; sports two antennas: True G is Airgo’s alternative to True MIMO, which employs multiple simultaneous data streams over different paths when endpoints are using Airgo’s technology. True G only has two antennas to True MIMO’s three—as sold by Linksys, Belkin, and others. A company spokesperson explained that the reduction in cost was achieved through fewer antennas and a lower component count.

Airgo has been frustrated in its attempts to capitalize on MIMO as a term that they “own”: True MIMO is a trademark, but Airgo also wants MIMO to refer only to those devices that use spatial multiplexing. (Some dispute Airgo’s founders position as the inventors of MIMO, too, citing earlier papers, but the founders’ early work in the field is what’s been instantiated as product by them.)

True AG chipsets will also be available for 802.11a and g range extension. Both True G and AG will have two receive and two transmit antennas; the True MIMO devices have three receive and two transmit antennas.

According to this article, Airgo expects street prices of gear based on their chips to drop to $129 to $149 for True MIMO and $69 to $99 for a router for True G. True AG will be slightly more expensive.
