Belkin said on Monday that they'll be releasing a wireless network card and router that uses pre-802.11n multiple-input, multiple-output (MIMO) antenna technology created by Airgo Networks. Belkin said the new pre-n products will provide four times faster speed and coverage area than 802.11b and g products. The new products will also be compatible with older products and in fact will increase performance on those older products.
"Our research shows that, with current wireless technology, people are experiencing poor coverage and performance at farther distances in their homes due to interference from other wireless networks, cordless phones, and other appliances," explains Eric Tong, VP Marketing and Product Development. "Our Pre-N products with True MIMO will empower users by providing a wireless network that makes poor coverage issues a thing of the past."
Belkin utilizes True MIMO (Multiple Input Multiple Output) from Airgo Networks in its Pre-N products. True MIMO is the first technology to address the issues of coverage, speed, and interference in larger homes and offices.
True MIMO is a smart-antenna technique that uses multiple antennas to transmit and receive wireless signals. It reaches a step further than other smart-antenna technologies by transmitting multiple signals on each antenna. As a result, Belkin's Pre-N products with True MIMO technology create a robust wireless connection while providing a larger coverage area with the bandwidth and quality of service needed to run advanced applications, such as streaming video or Voice over IP (VoIP).
True MIMO is one of the underlying technologies being considered for 802.11n, a standard in the works for the next generation of Wi-Fi technology.
"True MIMO is a breakthrough technology that fundamentally changes the way radio waves are sent and received. More importantly, True MIMO changes the way consumers are able to use wireless products," says Greg Raleigh, Chief Executive and President of Airgo Networks. "The immediate performance benefits realized with True MIMO, especially over expanded coverage areas, are why this technology has been chosen to power the upcoming 802.11n high-performance wireless standard. Reliability rivaling that of wired connections and effortless connectivity at real-world distances is why Belkin's True MIMO products have ushered in a new era in wireless."

Now, it seems, people are going to be rushing to these new "standards". Sure, if you're going to be transfering a lot of large files around your internal network, perhaps while you stream real time video to your "entertainment center", then you might justify the extra cost and being on the bleeding edge; but most users just think in terms of "I want the newer faster stuff" or simply "I want the good stuff" and they will end up paying a lot more now for the technology they never use than they would if they just waited until the standrds were worked out, the products came down in price, and the connection to the rest of the Internet caught up in speed to justify the choice.

That's not the way it should work. You should be able to set a g network to g-only. Even in the default of b+g, you lose a little throughput because the broadcasts are sent out in b in case anyone with b is listening. But the g clients transmit at g. The AP tranmits to g clients at g. The b clients transmit at b.
The effect is that if you have 10% broadcast traffic (usually at 2 Mb), 45% of t

Think of it this way, with only a little cable-pulling effort in your home (an investment) you are adding oodles of bandwidth. And if you need more, pull more cable.
