  1. Turbo Codes Promise Better Wireless Transmission

    captain igor writes "IEEE is running a story about two French professors that have created a new class of encoding, called 'Turbo Codes,' that will allow engineers to pass almost twice as much data through a given communications channel, or equivalently, the same amount of data at half the power. The new codes allow the Shannon Limit (the theoretical maximum capacity of a channel) to be approached to, currently, within .5 dB. Scientists hope that this breakthrough will revolutionize wireless communications, especially with the coming reclamation of large swaths of the EM spectrum." As the article points out, such codes are in use now, but seem poised for much wider implementation.

  2. Wireless Hotspots in a Large Environment?

    matth asks: "So here at work we provide wireless internet access to customers all over our city, and into suburbia, via Alvarion radio gear. We have a large number of customers that are places like pubs, libraries, restaurants, etc. We would like to, in conjunction with these locations, setup up a public Wi-Fi network. The problem is getting the mac address back through to a central authorization server. What experience have others had in setting up a Wi-Fi hotspot network over a city, and allowing a user to register at one location and get on at any of the various locales?"

  3. Wireless Technologies for ISPs?

    PhraudulentOne asks: "I work for a small rural ISP in Canada and we are planning to offer highspeed internet access (512k-2Mbps) for our rural customers that are too far down the line (or are unlucky enough to be in another carriers area) to receive DSL access. I am wondering how many of you have had success deploying wireless over a 3-10 mile range and what technologies worked for you. I have deployed a 2.4Ghz solution in the past by Alvarion but this time I am interested in the possibilities of 5.8Ghz/3.5Ghz/900Mhz or 2.4Ghz. I have looked at some technologies (ie. Angel) that work in the 1900Mhz spectrum as well. NLOS (non line of sight) would be great which 900Mhz works well with, but high bandwidth would also be a plus."

    "I am also thinking about providing hotspot access in some of the neighbouring towns so the locals can hang out in the parks or their backyards with a laptop and get some decent bandwidth. We could use PPPoE to offer a paid service (cheap!) for anyone to roam around the town and be online outside (hopefully 100% coverage). Some of the towns here are only 2-4 square miles so we could put up a couple of towers and cover everyone using technologies like ADC's Loopstar. Basically there are a lot of Wireless companies starting up and it seems like a fierce market - I would like some recommendations on companies that have been around for awhile and that you think will still be around in a couple of years - It seems I get a lot of PR and little substance from the ones I have been dealing with thus far."

  4. World's Longest Wi-Fi Connection

    axonis writes "The Swedish Space Corporation (SSC) announced today that they have transmitted information via a broadband wireless link over a distance of 310km. They believe that this is the longest distance achieved using wireless connectivity. Alvarion (BreezeCom) is also the original consultant to Ericsson for BlueTooth technology"
