[WISPA] Cisco on calculating RF values
I found this URL while googling for more info on Brian Webster's response to my 4.9 question (on why smaller channels were more efficient). http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a00800e90fe.shtml I was wondering if 9db was the amount of wattage others here found was amount necessary to double indoor coverage (as opposed to 6 db for outdoor coverage).

Re: [WISPA] Cisco on calculating RF values
Rogelio, The Cisco website seems to be down at the moment but RF is still RF and it behaves the same way indoors as it behaves outdoors except of course if there are more obstructions indoors than outdoors. In that case, then yes, depending on the nature of the obstructions, more power would be necessary at both ends of an indoor link to have same bidirectional throughput and reliability as an equivalent-length link outdoors. A 6 dB power increase doubles the link distance. Doubling the LINK DISTANCE from/to an access point (assuming an omnidirectional antenna on the AP) will make the COVERAGE AREA four times larger (because the area of a circle is pi (3.14) times the radius of the circle squared). To simply double the coverage AREA of a circle (as opposed to doubling the DISTANCE of a link) would then take something less than 6 dB (assuming no obstructions and assuming a straight linear decrease in the peak number of sunspots that first appear during the time frame between the waxing and the waning moon in the month of December of every third even year after 1776). jack Rogelio wrote: I found this URL while googling for more info on Brian Webster's response to my 4.9 question (on why smaller channels were more efficient). http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a00800e90fe.shtml I was wondering if 9db was the amount of wattage others here found was amount necessary to double indoor coverage (as opposed to 6 db for outdoor coverage).

Re: [WISPA] Cisco on calculating RF values
And to further add to what Jack said: When you are tying to factor indoor coverage, there are soo many things to consider. Building construction is the big one. If they have metal siding on the house or if it is stucco laid over a wire mesh, the signal will be almost dead inside unless some of it sneaks in through the widows. Now if the windows have metallic tint on them that creates problems too. Add the attenuation of multiple walls and/or the possibility of a client location in the basement and you can see the pitfalls of planning indoor coverage (especially over a large geographic area). I would say that adding only 3 dB to get indoor coverage will be way to low. Think back to the days of analog cellular, when you could hear the signal fades and how you had to move around inside a building to get a good call. That was at 800 MHz, go higher in frequency and the signal gets absorbed a lot more by building materials. It's really a nightmare to try and plan for, especially in the unlicensed spectrum.

Re: [WISPA] Who stocks PacW DP feeds
You have some Comet. But to get most of the rest, stock Hyperlink :) Mike Brownson wrote: The NS2 is a long story and not suitable for the list.

On the web site, if it says call for availability it means there are none in stock and the lead time has not been entered for that product. So you're right to think that it's not going to ship the next day. But I'll pass your note on to the product manager for Pac and see about uping the levels for the 29DP. I thought it was normally a stock item. But sometimes we run out before the next shipment comes in. Again I'll check. Thanks. Mike B From: [EMAIL PROTECTED] on behalf of Tom DeReggi Sent: Wed 9/24/2008 2:24 PM To: WISPA General List Subject: Re: [WISPA] Who stocks PacW DP feeds Well... I've always been a big fan of Hutton/Electrocom, and they do sell them, and have a great price on the feeds. Stocking of DP products is a different story. Unfortunteately, the majority of the time, when I need them , usually the last minute :-), the parts I need are usually "check for availabilty". :-( That makes it hard to place an order at 8pm online, when I finally get time, and get a sense of whether the product will arrive on time for my need. So I was just looking for additional options. I was also wondering if Pac's model is now just for vendors to have Pac just Drop ship, and vendors generally not planning on stocking, which would also be OK. On an ongoing basis, I just don't want to have to wait for a product to be shipped to the distributor, and then from distributor to me, as that duplicates shipping costs and/or slows delivery so the distributor can coordinate lower cost bulk shipping methods to get it to them first. Its worse when I'm east coast, and distributor is west coast. I believe in distribution, when distributors are willing to stock the merchandise regularly. But in the past, very few vendors have been willing to stock DP products. I'm concerned on what availabilty will be in the future also. For small radios, and stuff, the arguement is always The WISP should buy larger quantities and stiock more inventory. But Parabolics are large antennas, and take up a lot of space, so generally don't like to stock a lot of them in our "office" environment. I'd rather overnight a feed, or buy the full dish more locally. Now that Pac is refusing to fill orders direct, for these little things, I hope distributors will pick up the slack, so we don't have to wait 2 weeks, everytime we want a DP antenna.

[WISPA] Looking for webcam/security software
I'm looking for software that records video and audio from a windows computer (client uses a cam attached to a computer) whenever motion is detected, and uploads it to a remote server. This is, of course, part of an investigation or evidence collection (not sure which) dealing with divorce/children/domestic violence. Thus, the need for the software to automatically upload to a remote location to prevent its being found and deleted by the party under investigation. If you know of something, I need some help ASAP with this. Much appreciated. insert witty tagline here - Original Message - WISPA Wants You!
