Multiple-input multiple-output (MIMO) wireless uses different waveforms on typically two, but sometimes three or more transmitting antennas inputting to the channel
carrying radio waves from Point A to Point B. Multiple antennas and radios (typically, two or three) also are applied to the
output of the radio channel at the receiver, along with a lot of signal processing, which ideally improves range and throughput
compared with simpler or traditional radio designs operating under similar conditions.

Open source has moved into a new phase where it is evaluated more on its technical merits than on the community model of software development. Here's a collection of established companies, up-and-comers and outright start-up projects worth watching.
Juniper's relationship with Packet Design
11/09/09
In our Oct. 26 WAN newsletter we discussed the fact that there were a number of rumors circulating about a dramatic move that Juniper would soon announce. On October the 29th Juniper used the New York stock exchange as a backdrop to make a series of announcements. We are doing to use this newsletter to focus on one piece of the Juniper announcements – Juniper's establishment of a close relationship with Packet Design.

Despite the inclusion of "for Federal Information Systems" in the title, SP 800-34 Rev 1 has a great deal of value for all information assurance and business continuity specialists.
MIMO is sometimes referred to as spatial multiplexing, because it users a third, spatial dimension - beyond frequency and time - as a carrier for information. The multiplicative effect of properly designed MIMO systems can be dramatic: As our tests show, the 100Mbps barrier (application-layer throughput) in wireless LANs has been broken. Indeed, the upcoming 802.11n standard will likely specify raw (physical layer) performance as high as 600Mbps via a 4-by-4 MIMO array.
MIMO is also likely to have an influence on so-called 4G cellular designs, but that's a different story.
