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.”

I have the Belkin Pre-N wireless router (the funny looking one w/three ant.).
Blows my old D-Link products away with it's range. I was able to turn off the wireless repeater at the far end of my house once I got the Belkin Pre-N router. Wired portion works well with DVArchive, overall I'm quite happy with it- if you need range and speed.... it's a very good product.


BTW: The only minor annoyance with the product is the inability to use the remote wan management GUI. Belkin says it's because my ISP (cablevision) is blocking port 80 requests. The simple workaround is to use the router and create a virtual port (say 50025) and forward that to internal port 80. This way you can get remote router management.
When I asked the level II Belkin tech support why they don't let the user choose/configure the remote management port, especially since they said "some ISP's have begun blocking port 80 requests", they said "that request is on the wish list".......
