  1. my prediction on Cringley Asking for 12 Month Predictions · · Score: 1

    it will be discovered that Cringley murdered his own child to distract the world from the controversy surrounding his 802.11/2.4Ghz passive repeater hoax, and his credentials from Stanford will be shown as yet another lie in his desperate scheme to attain relevance.

  3. Re:The real problem on Report: Broadband Too Expensive For Many · · Score: 2, Informative

    I think the out will be wireless. Consider this plan. A large web provider provides 802.11b points of access all across San Francisco, and offers to sign up people for $20/month. Like someone who really needs to expand their broadband offerings (AOL or MSN, maybe). Shower the consumer with those stupid install CDs and free 802.11b cards. That quickly becomes an easy game for whoever will play.

    you clearly know absolutely nothing about 802.11. first, only 3 channels out of 11 (in the US) do not overlap, which means the others are essentially useless. Each user of the shared medium degrades the connections of the others. Any APs operating within range of each other on the same channel similarly degrade performance. Couple that with 2.4ghz's basically shitty penetration characteristics (for something like this, anyway), and it quickly becomes obvious that 802.11 would simply not do what you describe.

    Not only that, 802.11b cards are still around $60 retail, at the cheapest, and wouldn't work for reliable access anyway. You'd need some sort of reliable, outdoors friendly non-mobile CPE. Also note that apartment building owners are required in many states to allow you to install satellite tv antennae, but those protections do not usually include simple data transit devices.

    Wireless connections for high speed internet don't scale at all.

  4. Re:To those who've never been there.. on Starbucks Clashes With WiFi Hobbyists Over Airwaves · · Score: 1

    have you even used a wireless network? the card searches for the network based on ESSID, i.e. "tmobile" and doesn't really give a rat's ass about the channel, other than starting at #1. So, absolutely no configuration changes would need to be made, because your essid should have already been set to tmobile.

    Please stop spreading FUD borne of ignorance.

    we also talked to the site survey team, which you would think would have the capabilities of adjusting policy to reflect each individual situation. but, apparently not.

  6. Re:802.11b supports overlapping networks on Starbucks Clashes With WiFi Hobbyists Over Airwaves · · Score: 1

    Actually, they do, and the slightly different frequency (i.e. channels) is EXACTLY the issue. We were using channel 1. They came in, did a site survey, and still chose to use channel 1. this is a bad idea, on their part.

    And, the range of the free network has been decreased by the channel interference.

  7. Re:802.11b supports overlapping networks on Starbucks Clashes With WiFi Hobbyists Over Airwaves · · Score: 1

    only 3 802.11b channels don't overlap. 1, 6, and 11. 1 and 11 were being used before tmobile showed up. if community groups start hopping channels as soon as anybody else shows up, the concern is that eventually we'll run out of room and get the shaft, even though we've been there the longest. which is probably what will happen anyway, but we'd at least like people to notice.

    starbucks' performance is degraded by personaltelco, that's a big point of our position. and it's unfortunate.

    possibly, other than the fact that we discussed the existence of other wireless networks with the SITE SURVEY team. you know, the people that came to SURVEY the SITE.

    not only that, the whole ball of wax is handled by t-mobile, who should really know better.

  9. Re:Being "The Most Wired City" has it's downfalls. on Starbucks Clashes With WiFi Hobbyists Over Airwaves · · Score: 1

    just a quick note: pdxwireless is mostly defunct, at this point, and their map database isn't really being maintained, so it's probably fairly out of date.

    the personaltelco map server is actively maintained, and probably provides the most accurate depiction of intentionally open nodes in portland at the moment.

  10. Re:Does it matter? on Starbucks Clashes With WiFi Hobbyists Over Airwaves · · Score: 4, Interesting

    the problem is rather simple. imagine another wireless isp, building a similar tower 10 feet away, and trying to use exactly the same segment of the RF band to serve its customers.

    you get an insane loss of reliability and signal.

    personaltelco would be fine with moving our AP to another channel, but we're loathe to establish a precendent.

  11. Re:Stick to the standards on Starbucks Clashes With WiFi Hobbyists Over Airwaves · · Score: 2, Informative

    um. we're using 802.11b. the industry standard.

    the problem is that the IEEE defined 14 channels, or sequences of frequency hops, 11 of which are legal to use in the US. only 3 channels don't overlap at some point. Those channels are 1, 6, and 11. In Pioneer Courthouse Square, before t-mobile, there was a weak AP on channel 11, and personaltelco on channel 1. Logically, you would assume a for-pay service interested in providing quality would use channel 6. Even the most cursory of site surveys would've detected these competing signals.

  12. Re:Who was there first? on Starbucks Clashes With WiFi Hobbyists Over Airwaves · · Score: 3, Informative

    T-mobile was made aware of the free access both during site survey and installation (we happened to be around both times).

    Nobody, especially personal telco, wants regulation, and nobody's saying that they chose channel 1 maliciously. But, there's a problem. Staying on channel 1 will hurt their quality of service just as much as ours, if not more, since people expect more when they're paying for it.

    that's entirely incorrect. just because you were not aware of it does not mean "virtually nobody" is aware of it. it gets quite a lot of usage.
