Clearly thresholding latency and jitter is useful, but assuming neither are too high how does one know about the quality of a call. A MOS score would be more ideal. -Matt WISPA Wants You!

Re: [WISPA] Antenna Performance
http://www.radiolabs.com/products/antennas/2.4gig/2.4-aluminum-parabolic.php If you've got to go 10 miles, then you need gain. From the website. *2.4 GHz 24db Directional Parabolic Grid WiFi Antenna* *The Directional High Gain WiFi Parabolic Grid* WiFi Antenna offers 24dBi gain at the connector and a tight 8 Degree beamwidth. The high gain wifi antenna is an aluminum die cast which is then powder coat painted for added environmental protection. Because of its grid design the antenna offers excellent wind loading characteristics. Michael Baird wrote: Marlon, Not sure what you are saying here. According to the vendors specificatons. Teletronics 15-124 - 19DB horizontal w/8 degree vertical beamwidth. Tranzeo TR-24H-120-16 - 16DB horizontal w/6 degree vertical beamwidth. Yes it is odd that the Teletronics claims a higher VB, but then again it, it cost a lot more and should be a better antenna, as I believe gain not only comes with narrowing coverage (sector width), but antenna design. Regards Michael Baird Gain only comes from narrowing coverage with antennas. If there are both 120* antennas you can't have HIGHER gain with GREATER coverage It takes half the coverage area go give you twice the power (3DB of gain). http://www.odessaoffice.com/wireless/antenna/how_to_pick_the_right_antenna.htm laters, marlon - Original Message - From: Michael Baird m...@tc3net.com To: WISPA General List wireless@wispa.org Sent: Sunday, June 28, 2009 2:32 PM Subject: Re: [WISPA] Antenna Performance Not ,the same downtilt angle, same percentage as the old one. The previous antenna was a Tranzeo 16db w/6 degree vertical, the Teletronics 19db has a 8 degree vertical actually larger VB then the 16db at 6. They are both at .3 degrees downtilt. The only reason I mention the VSWR is because the teletronics VSWR is 1.1:4, vs 1.5 on the Tranzeo. The Teletronics is down about 6db on the CPE side for all the clients on the test sector, on the AP side it's the same. I tested multiple tilt's as well, between 0-1 degree was the best on the CPE side. Regards Michael Baird First thing that comes to my mind reading your post is that you installed a higher gain antenna which means your vertical beam is going to be narrower (sometimes higher gain is not always better). Being that you installed the antenna with the same down tilt angle your missing the mark because you have a narrower vertical beam. As for the VSWR nothing really considered too low. If your VSWR is higher then 1.5:1 then you have a problem for sure. Personally never used or tested TT's 15-124 antenna but have sold a few of them with no complaints on it as far as I know. -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Michael Baird Sent: Sunday, June 28, 2009 8:33 AM To: WISPA General List Subject: [WISPA] Antenna Performance I picked up a Teletronics 15-124 19db horizontal antenna for testing and deployed it in place of a Tranzeo 16db Horizontal (TilTek?), using same pigtail and radio.

Nothing was changed other then the antenna, aimed to the exact same degree, tilted the same percentage of vertical tilt, and so forth.

Re: [WISPA] email black lists
Our exim email server was compromised a couple of weeks ago by an offshore spammer. An absolute nightmare. After we took care of that vulnerability and added SPF records support, we had to file individual appeals with a number of upstream providers including Comcast and AOL to get permission to start sending emails again. There's one other thing you could do - change the IP address of your server, since block lists often seem to be tied to a specific IP. Tom S. - Original Message - From: Marlon K.

Re: [WISPA] Antenna Performance
I decided to just upgrade the whole thing and install sector antennas. It'll eventually go that way anyhow. This spot is the farthest out we reach but last week, out of nowhere, the calls started to come in from that area asking about service so I guess a real upgrade is in order. I have a set of 2.4 sector antennas that have been sitting around unused so I guess that can be the home for them. The 5.8 however, any suggestions on that for sector? Again, going into the 600a routerboard, R5H cards. My 2.4ghz sector antennas are 90 degree, so we'll be using 4. If we use 1 card for each sector on the 2.4, then go with 3 antennas for the 5.8 and use our Ubiquiti XR5 for the backhaul, that's going to fill up all 8 slots on the 600a. Never been to that point before, will our 48v POE run this whole thing or should I just add another routerboard for the 5.8 and the backhaul?

[WISPA] HotSpot users and FCC Reporting
Hi, I have asked this question before, but I have some new MTU buildings that I am setting up more as a hotspot. So people don't have to sign up with me and get installed, they just get on if they want to either daily or monthly. I have a lot of people who haven't given addresses or have given addresses in other states. Probably their billing address. So do I make up the jurisdiction they are in? This is not so hard now as I don't have that many. But later on (hopefully) it will be harder. Perhaps we should entice the FCC to think about this more carefully when they want us to report to them?

Re: [WISPA] Could Radio Waves Replace Fiber?
Really cool! Except, Singleton started to lose me when he gave hypothetical uses for the technology. Why does radiowaves have to go the speed if light, for it to pin point a tumor inches away, or why would a pencil beam be more benefical for satelite cell phone technology. Somewhat clueless examples. I will say, millimeter wave technology is already being used for medical uses like pinpointing tumors, but it doesn't need to go the speed of light. Now If they were to use that speed of light pencil beam for my Network Backbone... That would be cluefull :-) As for... Can radiowaves replace fiber? Well, the problem is not just getting waves to travel the speed of light. The problem is whether enough of the wave detail can be received, a long enough distance, without errors and distortion, for it to be useful and reliable. It can be challenging when the medium (air, rain, wood, etc) in which the radiowave travels through is not a constant, compared to fiber and wire technologies which are more consistent mediums for passing electricity or light. It will be interesting to follow Singleton's work.

Re: [WISPA] Antenna Performance
That's assuming you're using 2.4 and 20mhz channels. I feel it is only wise to use 10 or even 5 mhz channels. You drop those laptops that can see the AP and think they can get service. You cut interference in half and focus the power in half the bandwidth (bit more coverage!). You can only use things that can use the smaller channels.
