Re: [WISPA] Bandwidth pricing...
On Aug 10 2007, J. Vogel wrote: I just received a quote from AT&T for various levels of bandwidth through bonded T1s, where they are quoting not in multiples of 1.5, but in 1mbps increments. Seemed strange to me. However, what I found to be even more confusing was that as the total bandwidth increased, the price/mbps also increased, so that a 10 meg circuit costs $50/mbps more than a 7 meg circuit. Is this common? Is there a rational explanation for it? Thanks for any help understanding this. I've seen similar things when pricing partial T1 bandwidth. Anytime fractional circuits were involved, the price/mbps went up. Optimal price points were for full circuits, but full circuits may only make sense when you can use the bandwidth. Sample quotes .75 mbps (1/2 T1) $400/month = $533/mbps 1.5 mbps (full T1) $450/month = $300/mbps 2.25 mbps (1.5 T1s) $850/month = $378/mbps 3 mbps (2 bonded T1s) $900/month = $300/mbps (Fractional T1s were priced based on # of 64kbps channels subscribed to, at about $33/channel. I have seen per channel pricing down to $25.) From the telco viewpoint, I understand that they need to install the same line, infrastructure, and equipment regardless of whether the customer wants a partial or full circuit. Therefore pricing reflects the full circuit cost, even if only part of it is in use by a customer. In your example they may be switching from bonded 1.5mbps T1 technology to a fractional 45mbps T3 depending on where the price breaks are at. WISPA Wants You!

Re: [WISPA] Nstreme2 Link & Pacwireless
You might also look at a proprietary PoE solution, or maybe regular 48v PoE with a DC-DC (48v to 12v) convertor on the end. You could also look a solar.

Running LMR cable works for short runs (20-30ft), but after that it just limits the signal too much. What we really need is an 800mhz Routerboard in the same form factor as the current RB532. :) Travis Microserv Jory Privett wrote: I have been doing some research and these seem great, almost.

Does anyone have any recomendations/experinces with any in particular? Do they support the MikroTik RouterOS? Just get something fanless and low-power, and you're good. I usually suggest "fanless" because you can get the whole No Moving Parts assembly, which means fewer things that can break; the benefit of that should be obvious :) Low-power is optional, but usually goes along with fanless, because otherwise your computer could cook itself. The biggest downside is probably the "some assembly required" bit - you're basically buying all the parts for a small desktop computer, and assembling them yourself. There's a bit of learning curve even if you've worked with desktop PCs before (those power supplies especially are tiny, and can be annoying to work with). Your first system will probably take an hour or two to assemble. It will be a bit bigger than a Routerboard 500 - probably six inches square, two or three inches tall. And you'll need "real" power, as you can't usually run these with POE. RouterOS is available for "standard" x86 hardware, which most mini-ITX boards would be. You may also want to look at the new Soekris 5501. I haven't tested RouterOS on it, but Soekris is standard x86 hardware, so problems are pretty unlikely. It's a single-board unit, so you don't have to assemble anything; you'll be getting a bit less performance at about the same price, but you don't have to spend an hour putting bits together. mini-box.com has a good selection of bits and pieces; I've bought from them before and they took good care of me.

Means they can either use the cell towers to triangulate the position of the handset, which works better as more towers become visible. Or they have an actual GPS receiver in the handset that may or may not be usable by the handset owner with or without a 'GPS feature' enabling subscription. The telco policy of nickel-and-dimeing for every little feature is very irritating, including how they handle data and SMS. -hk On Jul 21 2007, George Rogato wrote: What does that mean.

Re: [WISPA] OT amps and volts
A caveat with higher current capacity power supplies (esp. replacing one kind of battery chemistry with another) is their internal impedence characteristics may vary, and if the electronics being run assume a certain impendence, things may go awry. A specific case is replacing alkaline batteries in some electronics that depend upon the internal current-limiting impedence characteristics of alkaline batteries. In those electronics, if you try to use NiCads or NiMH batteries, the device sometimes misfunctions. (Alkaline batteries have a (much) higher impedence than NiCads or NiMH batteries, as a result alkalines don't like high-current loads like digital cameras. I think certain older film-camera flashes were among devices that don't repond well to NiCad/NiMH batteries). As far as using a higher current power supply on an AP, I don't think this will be a problem. For long runs it may be necessary to use a higher voltage (but same or slightly higher current) power supply than the original in order to overcome the voltage drop over the CAT5 run. If you use a power supply that puts out enough voltage but not enough current, the voltage will drop (to some degree) in order to make up for the current shortfall (basically you have a brownout). You can find voltage drop calculators using Google. Most CAT5 is 24 gauge wire. The AP should have an on board voltage regulator to bring the incoming voltage down to whatever the chipset needs, so being a few volts (say < 3) above the specified voltage at the end of the 300 foot run likely is good enough. If you open the AP and identify the regulator IC (possibly a three-legged 7805 or 7812), you can then look up its spec sheets for its acceptable input voltage range. That said, the closer your input voltage is to the regulator's output voltage, the cooler the regulator will run and the happier it will be. -hk At 09:43 PM 2/4/2006 +0100, you wrote: >Increasing the Voltage beyond the specifications will kill the radio. >Putting a higher power - (current) PSU shouldn't hurt the radio.

Re: Re[2]: [WISPA] Virtual AP
It might interest people here that Kismet is no longer a Linux-only software. There is now KisWin... http://www.renderlab.net/projects/wrt54g/kiswin.html The caveat is it requires a Linksys WRT54G or WRT54GS or similar to perform the scanning (as a wireless receiver), and the Windows PC displays the output. One should avoid WRT54G version 5 (serial numbers starting with CDFB) (it has half the flash and ram as earlier versions (2mb/8mb), and runs VxWorks) and latest WRT54GS (serial numbers starting with CGN60) (it has half the flash and ram as before (4mb/16mb)). BTW, linksysinfo.org has a review article that compares all the versions of the WRT54G's.

Re: [WISPA] verizon fios pricing (mobility and roaming)
Hello, There was some open-source work done that allowed generic 802.11 clients to roam around on a wireless network without breaking stateful/session-orientated connections. It was called Transparent Mobility, and there is code available on the SF site below. I believe it was actually put into practice at SOWN, but there doesn't appear to have been any additional recent activity on the project. Nonetheless it was an interesting way to solve the problem of not having built-in roaming capabilities in 802.11. The description: --- About Transparent Mobile IP This project aims to provide IP mobility across multiple networks, ensuring that all active TCP sessions will be maintained upon migration. No client side software or alteration to IP stack is required.
