Re: [nycwireless] Connectivity emergency in brooklyn
Turns out that my new phone lines have a Digital Subscriber Loop, which means no DSL. And Cablevision (this is in Brooklyn) can't do cable Umm..but doesn't having a Digital Subscriber Loop imply they really do have DSL infrastructure in the area? At the switching office they probably have a DSLAM (Digital Subscriber Loop Access Multiplexer). Those are used on the other end of a DSL modem connection. (DSLAM definition taken from http://public.pacbell.net/faq/dsl_faq.html) Perhaps you meant to say they have load coils or are beyond the 12-18k feet range? http://www.dslreports.com/information/kb/load+coil modem, either. Verizon refused to switch me to an analog loop, and even they cannot provide me with DSL. I really hate Verizon even more, didn't think that was possible. Are there any wireless ISPs (WISPs) in that area? Any coffee shops with wifi? (Think high gain directional antenna...)

Re: [nycwireless] Connectivity emergency in brooklyn
Whatever the issue, Verizon insists that DSL is not possible. There isn't a distance issue, it has to do the with the type of circuit installed. Verizon won't even provide DSL themselves :( Looks like the solution is going to be a very pricey SDSL line.

Re: [nycwireless] [ot] RFID payment stuff ...
thanks, i was under the impression that RFID had a much larger range (about a foot @ minimum), from another FAQ: What is the read range for a typical RFID tag? The read range of passive tags depends on many factors: the frequency of operation, the power of the reader, interference from metal objects or other RF devices. In general, low-frequency tags are read from a foot or less. High frequency tags are read from about three feet and UHF tags are read from 10 to 20 feet. Where longer ranges are needed, such as for tracking railway cars, active tags use batteries to boost read ranges to 300 feet or more. this is based on the 3 ranges (low - 125khz, high - 13mhz, ultra-high - 900mhz) i know of ... so they can technically be that close-range in custom applications? if it's that low @ such a close range what is the point of RFID @ all in a payment process like that (vs. swiping a card)? - jon - Original Message - From: rwf [EMAIL PROTECTED] To: jon baer [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Tuesday, November 18, 2003 10:33 PM Subject: Re: [nycwireless] [ot] RFID payment stuff ...

Verizon won't even provide DSL themselves :( Most likely it's Verizon's loop concentrator. What happened was NYNEX back in 93-94 decided that it'd be more cost effective by bringing in fiber to the basement of a building, then putting in a mini-CO there to connect to the NID of each apartment. I recall this being done to my old building around that time. It resulted in higher voice quality and all, but made it totally incompatible with the xDSL standards that came out a few years later. But you still have a few options. 1) Use IDSL. The loop concentrator should be compatible with ISDN, and IDSL (physically) uses the same signaling as ISDN. It's not as pricey as SDSL, but then again, it's not as fast either. 2) Use SDSL. But you knew that already. 3) Call up Verizon. Tell them that you need a phone line compatible with an alarm system. Supposedly this causes Verizon to try to provision an analog loop for you. YMMV on this one. 4) Call up Speakeasy (800-556-5829). Tell them that you need a ADSL circuit on a separate line because your line is on a loop concentrator. They should be more than willing to work with you on this one, unlike VZ. It does require a truck roll, so that does mean higher upfront cost. But it'll be cheaper than SDSL/ADSL, and probably faster. Oh, and feel free to refer my account (starfox) if you go this route.

[nycwireless] More U-NII Channels Could Mean More Interference
More U-NII Channels Could Mean More Interference Nov 19, 2003 Good news for companies that work in the unlicensed-spectrum bands. The FCC just released an additional 255 megahertz in the 5.470 GHz-5.725 GHz band for unlicensed devices. Those who can take advantage of this development include carriers and service providers that support unlicensed National Information Infrastructure (U-NII) devices, including radio LANs operating under Part 15 of the FCC's rules. The new spectrum also should help promote broadband usage in rural and underserved areas via wireless ISPs that are using unlicensed spectrum as their transmission mode. A downside to making more spectrum available is the increased possibility of interference between a growing number of users. The FCC now will requires U-NII devices operating in the 5.250 GHz-5.350 GHz and the 5.470 GHz-5.725 GHz bands to use dynamic frequency selection, which the agency calls a listen-before-talk mechanism, and transmit power control to provide federal users of unlicensed spectrum and services with additional interference protection. The agency also adopted a notice of inquiry and notice of proposed rulemaking to gather comment on what it believes could be a new way to quantify and manage interference among different services, including unlicensed ones. Calling it interference temperature, this proposed model for addressing interference takes into account the actual cumulative RF energy from transmissions of spectrum-based devices, and it would set a maximum cap on the aggregate of these transmissions, the FCC says. In contrast, the current approach for managing interference focuses on specifying and limiting the transmit powers of individual spectrum-based devices as the chief way to prevent interference. The NPRM seeks comment on various technical rules that would establish procedures and use the interference temperature model on a limited basis in the 6,525 MHz-6700 MHz band and portions of the 12.75 GHz-13.25 GHz band. While these band are used predominantly by satellite and fixed microwave services, there could be a tie-in with increased usage in the unlicensed bands. One Current Interference Buster As any company that has spent at least thousands to sniff out the source of interference to its wireless LAN will tell you, you can do it inexpensively, you can do it easily, you can do it right or any combination of two. However, a new, intelligent spectrum-management tool developed by Waltham, Mass.-based Cognio, which deals in cognitive radio technologies for unlicensed-band wireless solutions, may be changing that thought. The challenges in the unlicensed band have been in getting a grip on the complete list of participants on the band, those things that disrupt and how to overcome them, says Naresh Balinga, vice president of marketing. This is the ever-growing problem in the 2 GHz-to-5-GHz bands. As you see more deployment, you'll see more congestion. First hinted about in June, Cognio's product - now in prototype -- looks at the physical RF layer, sees who is using it and then pinpoints them, which enables the IT department to tweak its channels and to lock down the wireless LAN from intruders. It is based on Cognio's SAGE spectrum-analysis engine coupled with its ASTRA platform. It will be tested with an unnamed group of early partners, and it could go commercial next summer. Because one unlicensed WLAN user cannot force an interfering WLAN user from stopping operations, the only think it can do is tweak the parameters of its own network. [Using our product], the carrier gets the data (from the network user) about problems within the WLAN environment, and it then decides how to mitigate the problem, such as changing the channels an end user uses, Balinga says. This is akin to watering the lawn with the right sprinklers.

Re: [nycwireless] Connectivity emergency in brooklyn
When there's no copper - you are screwed one way or the other. The only way VZ will pull new copper is by SDSL or T1 order. Not true, if they have pairs for a SDSL/T1, then they can fulfill a dark pair order. The ILEC doesn't know what the CLEC is going to run on it, and they shouldn't care. If you really want to find out about the copper shortage situtation, you can always flag down a neighborhood lineman. They are the ones that can tell you upfront if there is an actual shortage, or the VZHQ is spouting its propoganda. What they might end up doing is re-testing a pair that has been marked as bad in the past. Sometimes they re-test with less stringent quality tests, just because they are so short of pairs. So they might give you a pair to shut you up, but it may end up being crap. Here in Boston, I have dealt with being on the crappy end of Cambridge, and let me tell you Verizon just doesn't have its act together, or are just plain old being cheap. It took over a year to get a T1 that would work reasonably well. This should serve as a word of caution to anyone shopping for real estate: make sure the location isn't a bandwidth slum. Of course this is one of the major reasons why wireless data has become popular. I bet there's not nearly as much 802.11b activity in Stockholm, where you get 10mb cable internet access for 37 Euros.

an alternative - it would be nice to start gathering statistics on usage an NYCwireless nodes. for NoCatAuth-based nodes, we could set up a central syslog facility - then the stats could be accessed through MYSQL/PHP etc and support any number of alternative mapping/visualization experiments. Emenity has built a system like this and could help setting one up for NYCwireless. our current solution is rather awkward though - if someone wants to try and wrestle with msyslog (which has native MySQL support but almost no documentation) that would offer a much better long-term solution. reporters always ask me how many people are using NYCwireless nodes, and i tell them i have no idea. you could address privacy concerns by applying a one-way hash to MAC address as you parse the Nocat log files On Nov 19, 2003, at 3:59 PM, jon baer wrote: would doing this type of map for nycwireless nodes be a privacy concern?
