MIMO is hitting the market, but what’s the future of the products shipping now?: This piece I wrote for Mobile Pipeline provides an overview of MIMO technology and some of the issues that will face buyers of technology today—will that gateway they bought work tomorrow? Well, sure. But you won’t be able to use the fastest versions of “true MIMO” as backwards compatible versions of future MIMO, almost certainly.
Remarkably, NewsFactor Network has a similar story with a bit of a different tack: that author focuses on spatial multiplexing and its ability to increase the effective carrying capacity of a chunk of spectrum. Atheros’s two radio, four antenna system transmits the same data over both radios; Airgo’s MIMO sends different data over each radio sending signals across different paths. Atheros increases range; Airgo increases data rate and range.
