My UBNT Solar repeater is up and running

[Wifi442]

This has to be one of my more crazy ventures. I have wanted to set this up for a while now and finally got it up and running. At my work they have a 50/20mbit internet connection and I always wanted to get that kind of speed. All I can get here is just 1mb DSL at best. I had no line of sight due to a 2000' hill/mtn in the way. Solution: Place a repeater up there! Power is provided by a 60 Watt solar panel and a 125amp hour deep cycle 12v Battery

Speeds across the link are simply incredible. Better than I thought I would ever get:
http://www.speedtest.net/result/388030796.png

Link is set up like this:

Internet side Bullet5-28dbiGrid-St.WDS Ch. 50 ///wireless 9 miles/// Bullet5-AP-WDS-25dbi-grid---switch--- Bullet5-22dbi-grid-St.WDS Ch. 152 ///wireless 6 miles/// Bullet5 AP WDS 28dbi grid House

All Bullets are 40mhz channel spacing and WPA Encryption. Pings are a solid 3-4ms over the link and it hasn't dropped one packet yet. My vonage works fine over the link as well as just about anything I can think of.

Signal Strength on the 9 miles link is -69 and -65 on the 5 mile. I still need to align the antennas at the work and home locations but they are probably pretty close.

Yes someone could mess with it up there, but it is a very remote area. So we'll see. Hope not.

I only manged to get a few pics while setting it up:

Thanks UBNT for the great product!!

[Wifi442]

So I was using channel 50 (5.250ghz) for the 9 mile portion of the link. I have been looking around and it looks like I can't use that because the antennas have too much gain (28dbi and 25 on the other end). If I read it right, I can only use 2dbi output power on the 28 antenna side and 5dbi on the other which obviously wont work. :roll: Can anyone confirm this?

If I set the 9 mile link to channel 152 and the 6 mile link to 160 the link speed drops considerably. Is that because the channels overlap? The antennas are pretty close together. If I moved one further away could this help?

If I can't use ch 50 or 58 then it looks like 40mhz speeds won't work as the 2 40mhz channels on 5.8 are just too close.

[remuda]

I think for the lower U-NII band, you're limited to 16 dBm + 6 dBi, and it's for indoor use only.

You might try channel 153 for the 9 mile link, and channel 161 for the 6 mile link.

BTW, cool setup.

Unless I am missing something the 2 bullet5's I have only give you channel 152 (5760mhz) and 160 (5800mhz) when set on 40mhz channel width. You can see in my last photo that the antennas are about 1.5 ft apart. If I hike back up there and place one of the antennas 5-10ft away could it make any difference?

[remuda]

You're right, 152/160. I've been using 20MHz widths, and was just now playing with 40MHz. Can't help with the antenna spacing, but I would think more spacing would be better.

"If I read it right, I can only use 2dbi output power on the 28 antenna side and 5dbi on the other which obviously wont work. Can anyone confirm this? "

Why do you say that? Or confirm what?

Why do you say that? Or confirm what?

I was just trying to find out what the exact allowable power is if I want to use 5.25ghz or 5.290ghz. The link works a lot better with one half on 5.2 and the other on 5.7.

I guess the simple question is can I use 5.2ghz on a link which has a 28dbi grid on one end and a 25dbi grid on the other, and if so what power level am I allowed?

WHT you seem to be the man when it comes to this stuff. I appreciate all the help as I'm sure everyone else does too :)

[WHT]

The Bullet 5 has been FCC tested with a Hyperlink 30 dBi grid antenna, in spite of the fact Hyperlink does not show that high of gain grid antenna on their website. The form factor isn't important, but the 30 dBi gain is the max allowed.

The UNII-1 band (5.25-5.35 Ghz) is for indoor use only, so thats out of the picture. And no, you can't stick it indoors pointing outdoors through a window.

The UNII-2 band (5.25-5.35 Ghz) is for indoor and outdoor use. The max transmitter output is limited to 250 mW (24 dBm). Unlike the UNII-3 band, there is no provision for increasing antenna gain when using point-to-point. That means you can't use an antenna greater than 6 dBi in this band.

The UNII-3 band (5.725-5.825 Ghz) is for indoor and outdoor use. The max transmitter output is limited to 1.00 W (30 dBm). For point-to-point operation, you can use an antenna up to 23 dBi before you have to use the "add one, subtract one" rule or for every dB you add in antenna gain, you have to subtract one dB in TPO.

I haven't gotten around to see just what it takes to isolate the antennas, as I will be using a similar back to back set up. If worse comes to worse, I'll have to have some vertical separation, horse blinders on the antennas, or a back shield.

Thanks for straightening that up WHT. Looks like i'm stuck with ch.152 and 160. Do you think I would gain anything if I changed one of the links to vertical polarity? (leaving the other link horizontal)

[WHT]

With only a few feet separation, changing polarity won't have much, if any effect...but you can certainly try. See what a six feet separation does, leaving both at the same polarity. If that doesn't work, try twelve feet. If ya still have problems, drive your truck between them for shielding and see if that has an effect.

For a cheap and easy mount for testing, use a threaded pipe flange and a length of pre-threaded galvanized pipe. Mount the pipe flange on a wood cross. laying on the ground with some cinder blocks.

Keep us posted.

Just wanted to update. Link has been solid now for almost 11 days with no problems. I've been using 5.8 on both links getting ~22mb. I went to the site on Saturday and everything looked good. Battery was fully charged. While I was there I separated the antennas. They are now about 30 feet apart. It seems to have helped. The 9 mile link just does not like 5.8ghz as I can only get a speed of ~22mb on that side of the link. I am thinking about replacing the 25db grid that is up there with a 28 grid I have. I am just kinda worried the 28 might be too big for the mount system I am using and the wind up there, we'll see. For now I am just going to enjoy the great connection I have, 22mb is still way better than I had! UBNT rocks!

[WHT]

See my post in the Bullet forum about not having to use a switch. I was thinking this morning if CPOL antennas might give better isolation, but if its working fine now, leave it.

I'll take a look. Would be nice not to have that switch up there that's for sure. Do you think it's worth it throwing a 28db grid in place of the 25? I already have it, no cost just another trek up there.

Just did a speed test and here is what its getting across the whole link a few min ago

http://www.speedtest.net/result/394387032.png (http://www.speedtest.net)

[WHT]

Adding 3 more dB won't increase your speed as you're already getting 5 dB over the -74 dBm receiver sensitivity for 54 Mbps, but it will improve your fade margin.

[pcampbell]

Wow what a neat setup -do you not worry about people stealing your stuff?

[WHT]

Not if he posts a few "DANGER - High Ohmage" signs :lol:

[Wifi442]

Thanks!

About someone finding it, I try not to think about it, but anything could happen. It's such a remote area its pretty unlikely. It's actually so hidden that you'd have to practically be within 50 feet of it to know its there. I was going to put up a IP webcam just for kicks/security but didn't have enough solar power left. Plus it'd just be more goodies for someone to grab if it was ever found.

I'm going on 20 days now and no problems or hiccups. :D

[pcampbell]

Cool, could you tell us about the system draw, charging, etc.

I am guessing something like 10 watts * 24 hours a day = 240 watt hours per day

60 watt panel * 4 hours gives you about 240 watt hours per day??? Seems like too close for comfort???

do you have a charge controller...

do you really need a 150 AH battery or is that more of a just in case it rains for 3 days type of thing?

honestly your setup has inspired me to look into putting something up on a mountain!!! :)

I also am interested in the ins and outs of solar recharging, as I want to put my 462mhz GMRS UHF (voice) 2-way radio on a solar panel.

The nice thing about your setup, is that a constant 24/7 low amp draw is VERY easy on a battery, no?

I am using a Kyocera KC60 60 Watt panel (http://www.affordable-solar.com/kyocera.kc60.60.watt.solar.panel.htm). I am using a MPPT solar controller Solar Converters PT 12/24-10TC (http://store.altenergystore.com/Charge-Controllers/Solar-Charge-Controllers/MPPT-Solar-Charge-Controllers/Solar-Converters-Charge-Controllers/Solar-Converters-PT-1224-10TC1224V-MPPT-Charge-Contlr/p1369/)

I spent a lot of time on www.solarpowerforum.net (http://www.solarpowerforum.net/forumVB/) before I got started. My calculations below are based on These Calculations (http://www.solarpowerforum.net/forumVB/showthread.php?t=1793)


According to my multimeter each bullet only draws just over 2 watts at idle and around 3.5 fully loaded

I have 2 bullet5's and a basic Linksys 4 port switch up there that draws 1.6 watts. Everything just happenes to be happy to run at 12v (no inverters/transformers or any of that)

So here is my power breakdown:

Each bullet est. 3 watts each (it's way less as I don't max the connection out all day). The switch uses 1.6 watts.

7.6 watts/hr * 24hours = 182.4 watts daily use

then take 182.4 and multiply by 1.5 for fudge factor 182.4 *1.5 = 273.6

Then divide that by your worst case sun hours to get the panel size

273.6 / 4.6 sun hours (Jan, southern CA desert) = 59.47 watt panel

The battery is pretty simple. You take the 273.6 number and multiply it by 5 for a 5 day safety margin.

273.6 * 5 = 1368wh / 12.8 = 106.875ah battery

Even if I did max the connection for a day or 2 it would recover in the following days.

The battery was actually given to me, so that's why I'm using it. It's just a 125ah wal mart deep cycle marine. I was told it wouldn't last over a year probably. If the repeater makes it a year then I might invest in a true solar battery.

I've been up there twice since putting it up there and each time the battery has shown fully charged. Each time I was up there the sun was down. Hope this helps. Check out that solar forum site mentioned above. There are a lot of smart solar people on there. Good Luck! :D :D :D

[jp498]

If you only have two things, a switch should not be necessary. A crossover cable would save you 20% power in such a case.

[WHT]

Yup...we done a lot of testing and confirmed that a hub or switch is indeed not necessary. Both a straight and crossover cable work, but I'd prefer the crossover.

[pcampbell]

thanks for the reply. i see the draw is a lot less than i thought. its always nice to hook things right up to the battery without losing efficiency to transforming. at the way you are using the battery, i see no reason it won't last a very long time.

[pcampbell]

i also have been to that site, i just was shocked at how much more power and battery was suggested than i would have thought.

[pcampbell]

Yup...we done a lot of testing and confirmed that a hub or switch is indeed not necessary. Both a straight and crossover cable work, but I'd prefer the crossover.

are the bullets auto "crossing"? If so why do you prefer xover?

i wonder if the switch is just so he can plug in a laptop when he is up there diagnosing and testing.

[WHT]

I did have a problem at one time using straight cables, but can't duplicate it. By using a cross-over, I *know* it won't be unexpectedly duplicated.

[Wifi442]

Next time i go up there i'll bring a RJ-45 coupler and put it in place of the switch. The coupler is probably not the best option but its the only easy way without hacking up wires etc.

I'm still getting strange problems and dropped packets when I try it on my other bullet 5's at home. It's quite a trek to get up there so it probably won't happen anytime soon as I don't want to mess with something that is basically working perfect right now.

[WHT]

I always carry some short 6" jumpers with an EIA-565-A jack one one end and EIA-565-B jack on the other to "convert" cable into a cross-over.

Solution: Place a repeater up there! Power is provided by a 60 Watt solar panel and a 125amp hour deep cycle 12v Battery

Hi,

I'm looking to build something similar.

That solar panel looks like a Harbor Freight unit. Could you describe your panel and charger? Are you limiting the voltage into the Bullets?

Thanks!

Alan

of course, it helps to read the whole thread instead of just the top page. LOL[/i]

[jp498]

I'm a big fan of www.altenergystore.com for solar and related dc power parts. Batteries I get locally now, as shipping is getting to be crazy expensive for heavy batteries. Harbor freight has good deals, but generally not for solar stuff.

Hi guys,

Can i make the following links?:

6.5 miles using two bullets5 and 29dB grid antennas.
15 miles using two bullets5 and 29dB Dish antennas.

The objetive is to link to points that have hill between them just like the case of this post.

So in your experience can this be done?? or do i hace to switch to NanoStation (250mW) on the 15 miles link??

Thanks:icon_biggrin:

[900mhzdude]

I think you will need 2 Rocket5M's with dish antenna's to do a 15mi link

[IsaacBG84]

I think you will need 2 Rocket5M's with dish antenna's to do a 15mi link

Ok, the problem is that my tech suplier only manages bullet,nano and power station units, so i think i cant use those babies for now, but in your experience have you ever stablished 15 miles link with bullets?

Thanks

[900mhzdude]

No I don't :-( but I Do have a 15mi link with 5.8 canopy BH's

I think 2 Bullet5's and 2 24dbi Grid Antenna's should do the job

[Dave-D]

Isaac, two Bullet M5 with two 30dBi
grid antennas should provide 5 to 10Mbps
at 15mi. assuming an excellent path.

[I don't know what 'hill between them'
means; you can't go through a hill!]

I would lock the channel width to 10Mhz
[or 5Mhz when it becomes an option].
That will improve reliability. Dave

[IsaacBG84]

Thanks dude , and dave ..

I have two points to connect: PointA and PointB, between them there is a hill or a small elevation that blocks the path for RF, so i am going to mount a repeater site on another elevated zone and from there i will resend the data from Point A to Point B.

In the repeater site i will use a crossover cable to connect the two bullet5 and bridge the data to Point B.

I will propose this to a guy that wants this link and see what happens i will post the results here if do the link.

Thanks

[jborne]

That is freakin awesome. Hopefully no one toys with it.

[IsaacBG84]

Hi,

Wich of this antennas could be the best for a 15 miles lin using bullet5?
Wich of those can be aligned in less time? difficulty?

Dish:
http://www.teletronics.com/tant58dish29dbi.html

grid
http://www.teletronics.com/tant58grid29dbi.html


I can use either bullet5 or nano5 units i dont have other option right know.

Thanks

[throwingwaves]

do you have line of slight with the link?

[IsaacBG84]

do you have line of slight with the link?

Yes i am pretty sure there is because on point is in the city and the another one is on top of a low mountain. i cheked out also with Radio Mobile the eye path and its clear

[Dave-D]

Isaac, the grid antenna has the advantage
of lower cost and much lower wind loading.

I would have recommended the Rocket M5
with its matching dish if you were doing this.

But if only Bullet or NanoStation, then Bullet. Dave

[WHT]

I have two points to connect: PointA and PointB,Any distances?

[BobcatGuy]

Im dissapointed, I read the entire post, hopeing to find out if someone took his repeater, but never did. The posts stopped, so that may be an indication...

Funny how he was worried about signal strengths and best setup. I think he should of been more worried about it walking away. Hope it worked out and is still running.... I wonder what hill it was on?

[WHT]

It was in a pretty desolate spot and you had to almost trip over it to find it.

[IsaacBG84]

Any distances?


Yes,


Office------- REpeater; site 6 miles, i plan to use two PowerStation5

REpeater site-------remote office 15 miles, i plan to use two bullet5 with 29dB grid antenna.

I Aprecciate your help

[Dave-D]

Why not Bullet all the way, Isaac?
Cheaper and fine solution. Dave

[IsaacBG84]

Why not Bullet all the way, Isaac?
Cheaper and fine solution. Dave

:icon_wink: Yes i guess that would do the job also. I also think it would be less costly to use only bullets; the only reason i proposed PowerStation for the first link (6 miles) is to save installation time not using exterior antennas.

A reseller here in Mexico sell to me at this prices:

PowerStation5 : 289 USD
Bullet5 : 119 USD
26dB grid antenna : 101 USD:icon_eek:

Minus some extra discounts. The antennas are Teletronics type...

[WHT]

That will work, though I would use Bullet M5 and 28 dBi grids all around. Four of eveything.

[sj3sa]

This reply is for a couple of posts earlier when they talked about how to connect both bullets.

so if you use a crossover cable, how do you inject the power... POE?

sorry im confused!

[WHT]

You use a patch cable from the power supply LAN port to the other power supply LAN port.

[chillywit]

1. So you connect the "out" jacks on each POE injector together with patch cord?

2. If the 12v Linsys switch is removed from this system, then won't an inverter will be needed to power the POE injectors? The inverter surely will draw more current than the Linksys switch, so this may not be a good alternative. Am I missing something here?

[WHT]

That's pretty confusion the way you described it, instead of trying to figure out what you are asking, do it this way.

PoE power injector #1 PoE port > Radio #1
PoE power injector #2 PoE port > Radio #2

PoE power injector #1 LAN port > PoE power injector #2 LAN port (with at least a 3 ft patch cable)

[chillywit]

OK, got it. But what about the power source for the POE injectors? You would still need an inverter to run them from the batteries, which would draw a heavier load compared to using a 12v switch.

[WHT]

I'm going to take a guess on what you are trying to do. You want to eliminate the 120 volt plug in the wall power supplies, but still have a PoE injector.

With the old PoE injectors that had a separate wall-wart power supply, this was easy to do. Simply get a 12 volt power supply with a matching plug that would insert into the PoE injector.

You can get passive PoE injectors from a third-party vendor, or make you own.
Scroll down to passive PoE injectors, http://www.streakwave.com/items.asp?Cc=POE&ItemMoveby=0&Nbm=17-101&Pbm=POE-48i12s-AFI&iTpStatus=0&Tp=&sTitle=1&FromNav=False

http://www.streakwave.com/Itemdesc.asp?ic=POE-INJ&eq=&Tp=

[chillywit]

Yes, thanks for suggesting using passive POE to supply power from the solar panel (battery) to the the Bullets.

[WHT]

You can make your own with a generic 2-port wall plate and two 8-position jacks. You can connect the power supply with a 5.5mm length/2.1mm diameter DC Plug & Jack pair or terminal barrier strips from Loews or Homo Depot (Greenlee or Ideal brand).

I get all three from Alarm CCTV http://alarmcctv.com/ecommerce/General/BrowseCategory.aspx?CategoryId=100303 MSC-PDC-F16, MSC-PDC-M16 , MSC-PDC-T as well as best prices for CAT5 jacks. Set up as reseller with them.

I call it my ghetto PoE injector.

This will give you some ideas: http://whtonline.com/Team_Ubiquiti/AeroWRX.png

Edited to add...
You can make an inexpensive patch panel with a 6-port wall plate for three devices.
For my workbench I have a pair of Leviton 12-port patch panels, one for a 12 volt buss and 24 volt buss. Same ting at tower sites, but I add a station protector in teh line.

[chillywit]

Cool. I'm making something like that but not quite as "ghetto.":icon_biggrin:
