Re: [WISPA] GPS Sync / or Sync between devices at site without GPS Question
I do not know how the Radwin Sync works. With Canopy, you do not lose bandwidth unless you do not have the timing the same. You can adjust settings in such a way as to not step on yourself and still have different bandwidth profiles with Canopy. I do not see why sync would lose any bandwidth, unless it is cause now you only have X Transit tie and Y receive tie instead of X+%Y.

Re: [WISPA] GPS Sync / or Sync between devices at site without GPS Question
Yes, with wifi based radio systems you can see less throughput with sync than without. With Canopy the DL% is fixed regardless if the AP is getting the sync pulse from GPS or generating it itself. i.e. if you set the DL% to 75% it's fixed regardless if the bandwidth is being used or not. With .11 radios the DL% is dynamic and will adjust according to demand (which is why they are NOT in sync with other .11 radios). When you sync them, the DL is no longer dynamic. So if you had a .11-based BH that has 90% downlink traffic and force it to sync the DL% may only be 50% which would look like half.

Re: [WISPA] GPS Sync / or Sync between devices at site without GPS Question
Right, allows sync between GROUPS. GROUPS can be as large as you want as long as the MASTER can be reached via Layer2 in less than 30ms. If you have two GROUPS (for example two tower sites) that can hear each other but can't be reached via Layer2 or latency goes above 30ms between them, then the MASTERS at both towers will need to have fixed DL% UBNT's GPS implementation is a little different than we are used to, but I like that they did away with the CMM concept. I am not sure I like the ide of depending on one radio for MASTER sync information. I would like to see some code that allows for failover. Something like: - APRadio1 is MASTER/MASTER - APRadio2 is SLAVE/MASTER The rest of the SLAVES in the group look at APRadio11 for sync info and if it's not there look at APRadioMAC2 - Jerry From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Mike Hammett Sent: Monday, January 10, 2011 9:40 AM To: WISPA General List Subject: Re: [WISPA] GPS Sync / or Sync between devices at site without GPS Question Ubiquiti's next software release is supposed to have dynamic ratios with sync. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com On 1/10/2011 11:25 AM, Jerry Richardson wrote: Yes, with wifi based radio systems you can see less throughput with sync than without.

Re: [WISPA] GPS Sync / or Sync between devices at site without GPS Question
Its safe to assume that the newer firmware with sync with UBNT will only work with the newer gen hardware with the gps support right. Is there any functionality that works like the radwin radios where the two local units speak sync between them without GPS? Even having the ability to sync two radios back to back to reuse spectrum would be really nice.

All of our gear in the past did not have the capability to sync across devices to save spectrum and/or reduce interference between local devices. In this case I used two Radwin 2000C backhauls with a sync cable between them. Setting up the sync between them was easy however the first thing I noticed was that the available bandwidth was cut in half. Is this typical of all synced units? I guess there would be no more reduction in speed after the first two radios synced because if there were more they would all fire at the same time any way. Did I loose bandwidth because they were in MIMO mode rather than Diversity mode or is the slowdown just a function of the timing reduction to keep things clean? Is the UBNT GPS sync gear going to provide less throughput than I currently experience when their new sync capable gear comes out?

Going in a different direction... Can you reuse a given frequency on every sector around a tower (4x or 6x), or are you limited to something less than that?

Re: [WISPA] GPS synced systems
With standard FSK Canopy (7/14 Mbps) you can re-use frequencies on back-to-back sectors only. There is no throughput hit for doing so. Think about what the GPS sync does- it causes all AP transmission timeslots to occur simultaneously, and all receive timeslots to be synchronized. So colocated APs will never be receiving while another is transmitting, avoiding self-interference. However, SMs receiving from a transmitting AP cluster must have enough separation between APs transmitting on the same frequency so that the signal from the desired AP is above the minimum SNR for the given modulation (10 dB for 2x mode) when compared to another AP transmitting on the same frequency. This can be achieved with a standard Canopy AP module by placing them back to back--the front/back ratio on the antennas provides more than 10 dB isolation. But a SM placed at the edge of two 60 degree sectors wouldn't have nearly enough isolation between the two sectors if they were running on the same frequency to maintain an acceptable SNR. So in short, you need three channels to run a standard 6 AP sector GPS sync'd with Canopy.

Re: [WISPA] GPS NTP Server?
I discovered that somewhere along the lines, MT added support for USB-based GPS. So I bought a $15 outdoor USB GPS off eBay. We'll see next week if it works. MT docs said as long as it supports NMEA output (which this one did) it'd work. We don't need accuracy down to the nanosecond, but within a second or two. We provide services to the local E911 PSAP, and need to make certain our end matches theirs for VoIP, log files, etc. For this app, we don't want to rely on Internet-based NTP servers, as some of our application is not tied to the public Internet.

Re: [WISPA] GPS NTP Server?
The last time I looked into this, the GPS had to be one that output a 1 pps signal, and most didn't. Of course times could have changed (pun intended) and this isn't a requirement any longer. The GPS-35 from Garmin may meet your specs, I think, if it's still made. And BTW- if you happen to have a Canopy CMM in your network, it also has the NTP server derived from GPS built in.

Re: [WISPA] GPS mapping software
SNMP would work if you just wanted to collect information about the AP's you are actually connected to. I don't think there is an OID for the scan feature, but I could be wrong. Anyone know?

Re: [WISPA] GPS mapping software
The biggest problem with your idea will be the fact you're on the ground - not going to work too well for 2.4 and 5.x. 900 will be better, but not ideal. The better part of what you're doing is if you see a -75 somewhere, then the houses adjacent are going to be greater to or equal! Starting out new the costs for everything - Brian's solution is significantly better. He offers it in Google Maps (great for show and tell) and Google Earth (great for installers/remote site surveys/etc).

Re: [WISPA] GPS
Magellan makes some GPS that include a GPS based compass to ignore the magnetic problems with some vertical assets. Will also work standing still, but uses batteries fairly fast with the compass turned on. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, January 29, 2008 4:00 PM To: WISPA General List Subject: Re: [WISPA] GPS We've been using the Garmin 70 and 60 series with altimeter (as opposed to elevation from map data).

Re: [WISPA] GPS
http://tinyurl.com/259a2f http://tinyurl.com/yrpqsw $40.00 to 10,000.00 is a big price range! My gps is WAAS or what ever enabled, but I have to be 25-30 feet away from the tower to get anything close to accurate on the compass. Altitude is close. We just use a land mark with Google Earth's line/measuring tool, and print it out before we go.

Re: [WISPA] GPS
One thing to watch with the compasses is magnetic distortion. When we are aiming a PTP link or sector we will use a compass and a reference point from google earth. This is especially important when on top of a grain elevator since they can have some large electric motors for the conveyors, which will throw off magnetic compasses. For installs we have given our techs MS streets and trips with the usb GPS dongle. Our Installer's vans are equipped with Jotto Desks and have tablets PC that allow them to use the Street and Trips for directions. Ryan On Jan 29, 2008, at 11:58 PM, Marlon K.

[WISPA] GPS coords
I'm finishing up on the link map/spreadsheet to send you. How accurate does the GPS coords need to be, for Freq Coord study? I'm using Google Earth.

[WISPA] GPS
Hi, Has anyone equipped their installer vehicles with dash-mounted GPS systems? We have been using the cheap USB GPS adapters with the installers laptops and using Streets 2007. This works pretty well, but now with the prices down on the dash mount models, I'm wondering about installing those. Any input? Travis Microserv WISPA Wants You!

[WISPA] GPS Recievers
I'm looking for very good GPS receivers. I've used Trimble in the past and found them to be very good, but expensive. That was back in 1998 - 2001. I'd like to get sub-meter accuracy if the price is right. When dealing with mountain tops and ridge lines, 100' off can put you at the bottom of a cliff. Any recommendations? -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
RE: [WISPA] GPS Recievers
Dan, I like the Garmin product line. To get the best accuracy for a reasonable price look for devices that have WAAS. This is a secondary differential correction signal sent from Geostationary birds on each coast. It does not always work but for the price it gets you real close. You should be able to get accuracy to 20 feet or better in most situations.

RE: [WISPA] GPS Recievers
/lurk You should be able to get accuracy to 20 feet or better in most situations. I routinely get 15' accuracy with my GPSMAP 60C. 9' is not uncommon. The best I've seen it was last weekend, when I had 6' accuracy while out in the desert east of San Diego. I'm a big Garmin fan. Both GPS units I've owned were/are Garmins. I know a few people with Magellans and they're constantly complaining of accuracy issues and quality control (stress cracks in the housing, etc). To the original poster: Unless you can manage to get your hands on a military grade device, you're not likely to get sub-meter precision. lurk -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
