Announcing LA County Coverage

I just finally received my Nanobridge 5G25 and have line of sight to Mt. Lee and the Verdugo Mountains in Burbank SFV.  I may be able to hit Oat Mtn.  Anything other than Pleasant Mtn or Northridge at the present time on 5Ghz in LA county?

 

Thanks,

There is discussion to create a link between Verdugo and Pleasants PK, timing TBD.  

AF6YN
Downtown LA Node

I have a Nanostation M2 (af6yn-dtla) linked dtd to a Nanobridge M3. Through the Nanobridge it is connected to Pleasants Peak. I plan to add 5GHz in the future. It might be easier for some to hit than Pleasants Peak depending on terain, obstacles, etc. Its located in an east facing window of an apartment building on the 14th floor with no obstructions (nothing to the east is as tall). Its lat/long is 34.04661/-118.24876. I've been able to link back to it from a number of east LA County locations (Alhambra, East Los Angeles, El Monte, Monterey Park, Norwalk, Temple City).
I have been playing with services on a Raspberry Pi (over time I'm moving the services to several Pi's and ITX linux computers) SMTP email, IMAP, POP3, FTP, asterisk/FreePBX, IRC, XMPP/Jabber, http, a small web CMS, a web based ticket tracker, a web distance and bearing from lat/lonng, Squirrel mail web interface, and Nagios (although I haven't done much with SNMP because the PI is the only SNMP enabled device of the lot - so its SNMPing itself is all).

Hope to connect soon/73,
Anne (AF6YN)

Lincoln Heights Bullet M2/NanoStation LocoM5 options

Hi Anne, I have some hardware I'd like to try to connect with... are you still up and running? I'm over near N Main where is crosses the LA River. I can get my antenna up to about 6 meters in height. I'll start hunting for your signal with my Bullet M2 and a 9dbi antenna.

In total I have the following equipment to work with:

1 Ubiquiti Bullet M2HP Titanium

1 Ubiquiti PicoStation M2HP

2 NanoStation Loco M5's

4 WRT54GL's

Bins of assorted IP/Telco hardware I have fiddled with over the years.

Hey Joe - is that first unit really on 2310 MHz?

In reference to the coverage area modeling...  The 'free' tool to model the coverage area does not allow the actual frequency (ch -2)  to be used.  I believe the paid version will allow this freq.

was able to connect to Pleasants from torrance
barely connected to pleasants from torrance using a nanostation m2. s/n is 11 db mostly. joe sent me an email saying the 2310 MHz is a workaround for the radio mobile display sw. I connected on ch -2 [2397 MHz] using the beta firmware. note the SSID is BroadbandHamnet, not the default AREDN. wow, lotsa services advertised! thru the linking, i was able to see af6yn-dtla content, but couldnt get a link directly. af6yn, do you have south or southwest exposure? maybe try ch -1 to get away from interference on that band? hows your s/n on the nanobridge m3 to pleasants? I was able to open the "information about node services". very nice, we need more content like that. LA county doesnt have a web presence like ocmesh.org yet? awesome website...... -ai6hj

As you might have seen in the
As you might have seen in the other forum post, the distance parameter needs to be set for these longer distance links to work.   I'll review the settings on the Pleasants Pk nodes for these 40+ mile links.  If too short, we'll get lots of extra retry attempts.     Get actual distance and round upwards a little.

Thanx! good 2 see u online!
Thanx! good 2 see u online! I'm a noob at all this. went bak to the config on the nanostation, and see the default is 100000 meters, and +28 dBm. is it possible to have too much set? also fergot to say the default bw was 20 MHz, had to change to 10MHz for connection. maybe i should be using a nano bridge instead? is the firmware the same? http://www.amazon.com/Ubiquiti-High-Performance-Integrated-InnerFeed-NBE... btw, is there an area for buying/selling/trading used equipment? i have been using this site to get distances and bearings....approx 42 mi http://www.heywhatsthat.com/profiler.html thx -ai6hj
AF6YN
Adjustments
AI6HJ: I just redirected AF6YN-DTLA to 199 degrees magnetic (toward torance) I have it set to SSID: BroadbandHamnet Channel: -2 Bandwidth: 10 MHz. Try and connect. If that doesn't work, I can try another channel (like -1), but staying out of the Part 15 wifi segment is probably going to give the least interference.

K5DLQ: I'll have to lookup/figure out the SNMP settings on the nodes, so I can keep track of health/performance with nagios (my preferred utility for alerting/tracking).

Many thanks to the AREDN development team for the firmware and updates (I just updated my nodes). And thanks to the node operators like AE6XE and KE6BXT that have set up nodes to provide a network infrastructure.

Hoping to connect and 73,

AI6HJ: I have the lat/long
AI6HJ: I have the lat/long for Torrance listed as 33.8347/-118.3414. That would put Torance to Pleasants Pk as Distance in Miles: 41, Distance in Kilometers: 66, Bearing: 93 degrees, Magnetic compass bearing: 81 degrees. And it would put Torance to Downtown LA as Distance in Miles: 16, Distance in Kilometers: 25, Bearing: 19 degrees, Magnetic compass bearing: 7 degrees. I knew the php script converting Haversine (great circle route) equations that I put up on my mesh web server would come in handy.

I like that idea of a Sothern to northern Cali backbone. 

Im starting to ping the BAY-NET group for East to south Bay Area Back bone. It makes me wonder what might be LOS south of that now. Any other info on a South to North backbone?

I forgot to add: is there anything that I need to do with respect to joining the group or can I just feel free to hang a node and join the fun?

I have a Bullet M2 with a Trendnet external antenna that is currently running BBHN in a completely experimental mode. The intention would be to put the omni on my satellite antenna crossboom. 

Rough idea of the location is DM03uu

Chris,   The more the merrier

Chris,   The more the merrier!    There is a "basic setup" link on the left menu of ocmesh.org to determine the settings and make a connection.   Is this a 15dBi omni antenna?   You would probably need the 27dBi grid to connect (recommend H-pol) at that distance to have a usable link.  Also, look on the maps on ocmesh.org to see--there is a 2ghz Nanostation sector coverage from down town LA at about  ~11 stories up that has a 3Ghz link to Pleasants Pk already.   Maybe you can also connect in there?

I have entertained the thought of installing the 5ghz model on a grid and pointing it north to tie into the backbone. I'd then use the DtD connection to provide local coverage on 2ghz.

Is there anybody in the group coordinating coordinating links? Not looking for administrative overhead, just want to make sure that I'm not putting up something that is already in the works or unneeded.

My QTH is on the southwest corner of the intersection of Maricopa St. and Crenshaw Blvd. I'm about 1 mile from the TPD / Torrance city hall complex so my site could be particularly useful from a connectivity perspective. The whole of the station, with the exception of the rotators, is on DC power (which needs a bigger battery!) with UPS feeding the charging system.

Please feel free (anybody on the list) to contact me at cspacone@socal.rr.com

Thank You, Thank You, Thank You Joe - It's Christmas in July

These RMO reports confirm there is a way to get RMO to use less than 1 Watt Tx Out <g>
I get the use of ubnt's .ant files but IIRC that doesn't get RMO to accept less than 1 watt of Tx Out.... or does it?
How did you do that?

I'm doing something wrong and shaking my head and muttering ' "...at least it shows where there *might* be coverage" as I watch RMO round my .3 and .6 w Tx Out up to -30 dbm  (maybe it is -29dBm). Is it that it needs a leading '0' before the decimal? 

Almost a year later are you still satisfied with the other settings you are using in RMO for Rockets?

One or all 3 of these RMO reports should be annotated and put in AREDN Docs for the rest of us to use as an RMO tutorial.
If I'm any kind of example that will leverage hundreds (thousands?) of hours of MESH Head shaking over the next few years towards more useful pursuits.

ASAP I'll run an RMO with the .ant file and then again if necessary with the .ant file and a leading '0' so the questions are rhetorical if either is what I've been missing.   (somebody please come up with an 'asciigram' for a 'dope slap' sound  <-:)!>  isn't quite right and my need is growing)

Suggestion / request  re: RMO tutorial is very sincere.

Fractional Power
I've never had trouble entering decimal values for power.  I typically set Rocket power to ".25"

I thought it might be a preference setting, but checked and there's no such restriction.  Hey, check to be sure your Status on the Settings page is set to "Amateur".  I know that commercial customers have more restrictions than hams. If it's not, then you may need to setup a new account configured correctly.

Ubiquiti ANT files
For those who may have had difficulty finding the Ubiquiti antenna pattern data files to use with RMO, you can ind them by searching on the UBNT Support page for "Airmax antenna data" to get this page.

Dan,  
Dan,  

1) <1W power:   I've not run into this. Consequently, not sure what I did right, or maybe a new 'feature' in RMO?  There are restrictions for free use, e.g. can't type in the 2Ghz part 15 frequencies (hence the 2310 that is in use on my models).  

2) Radio Mobile Online (RMO) tutorial:  great idea.  We'll discuss in the AREDN weekly team meeting.

San Gabriel Valley node
I'm working on a proposal to set up a 2.4 Ghz sector antenna above Monrovia/Arcadia/Sierra Madre in the San Gabriel Valley. I would like to link it to Pleasant's Peak and it looks like 3 Ghz has the best coverage in that area. Could anyone give recommendations on the best equipment to use for the link node? There is a clean shot 37 miles from the Santa Anita Ridge to Pleasant's Peak.   34.187239, -118.035238

Pasadena-San Gabriel Valley Emcomm Mesh

Just an update on this.  Over the past few days we have been working with Robert KC6TAV and he and his Sierra Madre team are now connected to our hub in Pasadena.  Lots more fun to be had here as we continue to work on this.

We have 5 GHz coverage from Huntington Hospital (on the AREDN map) to the south, and to many of the foothill communities to the northeast,  Of course Southern California terrain can be an issue, but if you can get over that, a link may be possible.

We continue to work on expanding the mesh in this area.  Let us know if you or your group are in the area and are interested in connecting.

Robert,

Intesting site!   I have a 2GHz node on a vertical/omni on the east side of Pasadena near Sierra Madre (34.165979, -118.072807) about 4.6km from your location.  My node is running on channel -2.   Feel free to try connecting to it.

Not sure what folks recommend now for 3GHz equipment, but I've used a NanoStation M3 + 32"+ reflector at that distance for a reasonable (not great) connection.   You can get a better connection via a Rocket M3 + larger Rocket Dish.   The latter is more expensive but it offers 2-3 times the bandwidth the former.

If you connect to a Pleasants Peak node, please coordinate with Joe Ayers, AE6XE.

Hey Jonathan! I saw your node
Hey Jonathan! I saw your node on the AREDN map and had added you to a list of people to contact to see if you wanted to come to an AREDN node planning meeting. We are primarily concentrating on a MESH network the Sierra Madre area, but it is easy enough to put up an antenna to get a lot more coverage. I don't have access yet to the Santa Anita Ridge site... I'm still working my way through a list of contacts related to the site to try and find out who in Arcadia oversees the main building. It looks like the ridge line to Jones Peak probably blocks you from seeing Santa Anita Ridge. Thanks for the suggestion to contact AE6XE, I had sent an email to KE6BXT but hadn't heard back. If you don't mind could you send me a message so I can get your email address?

Robert
