Ralink Technology Demonstrates Beam Forming

Tuesday, February 23rd, 2010

Hi today I found this, it is interesting press release from RALINK to find that there is a standard for beam forming.

Soon we can see cheap alternatives to Ruckus wireless. As Ralink is fully open source we can see open-mesh running on one of these. Yes Rukus uses special 12 or more elements antennas … but we will wait and see.

RT3883 and RT3593: The industry’s first commercially available single-chip 450Mbps 3×3 802.11n access point and station solutions with Beam Forming technology. The RT3883, featuring three dual band 2.4/5GHz  radios, a 500MHz MIPS74K CPU, and a variety of connectivity interfaces, is the most advanced Wi-Fi Access Point/Router platform in the industry. The RT3593 is the most highly integrated 450Mbps 3×3 client solution available on the market with an embedded media access controller, baseband processor, and three dual band 2.4/5GHz radios on a single chip. Both RT3883 and RT3593 chips incorporate Ralink’s high-performance radio and baseband architectures, delivering best-in-class Wi-Fi performance, low power consumption, and cost-effective price points.

The RT3883 and RT3593 chips are also the first single chip 802.11n solutions which support the IEEE standard’s optional Beam Forming functionality. With Beam Forming technology, the RT3883 and RT3593 intelligently determine a receiver’s distance and location, control various transmission parameters, and optimize the Wi-Fi signals to maximize throughput, range, and reliability. This break-through technology enables superior Wi-Fi coverage, interference mitigation, and more reliable connections for data-centric and video-over-WiFi applications. The RT3883 and RT3593 support the IEEE’s optional 802.11n Explicit Beam Forming standard and also incorporate Ralink’s 802.11n Implicit Beam Forming technology which improves performance even when communicating with legacy 802.11a/b/g or 802.11n devices that do not support the IEEE Beam Forming protocol.

Ralink RT3050F CPU,
MX25L1605DM (16mbyte chip),
M12L2561616A-6T (4M * 16bit)
USB pinouts – maybe ?

The good think is that ralink have everything open source.

Martin In Tears As Foneros Rip Him A New One

Monday, February 15th, 2010

Looking users are angry on Fon for showing new products and stopping to support old buggy 2.0n routers.

Martin’s cheerful post yesterday, about yet another router model, didn’t go over well with the Community of worldwide Foneros. Comments were open, so everyone jumped on poor Martin’s case about the previous router models which still aren’t stable, particularly the latest one, which has been abandoned for several months with major issues still pending.

Martin’s blog post is an absolute HOOT to read. The angry, cheated Fonero Community descended upon him, demanding action, and his response was to literally cry and attempt to make Foneros feel guilty that his skeleton staff is overworked. Sorry Martin, that’s not our fault!
