Fon has decided to open our WiFi network in Japan to all for free

Fon has decided to open our WiFi network in Japan to all for free

http://english.martinvarsavsky.net/general/fon-has-decided-to-open-our-wifi-network-in-japan-to-all-for-free.html

Fon’s WiFi network is by far the largest in Japan with over a million hotspots of which over half a million are on at any one time. Normally the Fon network is free to those who share WiFi (known as Foneros) and other users pay. Given the current emergency in Japan, and the failure of some mobile network as a result of the earthquake, Fon has decided to open our network to all of those in Japan. The software changes required are being worked on at our headquarters in Madrid and will be ready in an estimated 3 hours or around 6pm Spanish time. Japan is 7 hours ahead of us so it will be around 1am in Japan when all our hotspots are open to the general public. We hope those stranded or in need find the Fon network useful. We also encourage owners of Fon WiFi routers who may not have their Fon WiFi routers (Foneras) connected to connect them to help anyone who may need connectivity.  All this is being done in collaboration with our friends at Softbank who currently distribute Foneras in Japan.  We would like to send our condolences to the families of those who died in this sad tragedy and wish all in Japan a quick recovery from this natural disaster.

Update: Work done in Madrid, the Fon WiFi network in Japan is now open for all to use until the emergency is over. I would like to thank our colleagues at Softbank, our engineers in Spain and above all the Japanese foneros who make this possible.

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.
