Wireless Joint

I recently purchased a pair of these antennas (https://thewirelesshaven.com/shop/antennas/outdoor/outdoor-cellular/directional-panel/high-beam/) for my 4G project I've been working on. I couldn't find any good detailed reviews with these antennas, so I thought I'd share my experience with them. (I ...

Nice results! Thanks for sharing. Do you happen to know what the speeds are with just one of the directional antenna? Are two matching antenna needed to see such a large improvement? Or can you get significant benefit with just one? I don't really understand how MIMO works.


I have not done any ...

Update: with some interesting info

Yesterday afternoon, I had some time to play around with these antennas some more, and discovered some interesting things. My goal for this time was to test a few things.

1. Check signal strength and speed again (as compared to my previous test).
2. Test both ...

Wow, that's quite the difference! I bet you will get 2 to 3 times that speed with outside external antennas.

Do you have a screenshot of your signal status? It would be interesting to see that info.

After learning from this video and spreadsheet, I decided to try and see how the reference signal values I see with my 4G connection compare. This required a little bit of a reverse engineering, but I think I figured out a few interesting things.

1. I don't know how much power the tower transmits ...

I ran through another series of tests a few days ago, to compare the antennas again on a different day. This wasn't a 100% fair test, because of a few things.

1. Weather was a little bit "better" I guess you could say? Less humidity and clear skies.
2. I compared the flat panel antennas and the ...

Sure, I'm glad to help where I can! I'll address a few different topics/questions below.

1. I'm not sure what you mean by your modem/router is connected to Band 4, but is set for Band 2? Is that pictured somewhere in the screenshots? All I see is you connected to Band 4. You can "lock" your modem ...

I was doing some reading last night, and discovered something very interested. I was reading on Shannon's Capacity theory (I have read up on it before, but never compared it to real tests) Here's a link to a good video that explains it: https://www.youtube.com/watch?v=ancDN11C2vg

I started doing ...

Hi Jim -

I am using SMA connectors that I purchased from Air802. I know there are a lot of garbage products on the market from ebay etc. but these appeared to be high quality. The LMR400 cable is from Altelix...i'll have to test the cables next and get back to you. Thanks again for helping

I'd recommend a H20 sim card, which can be found on Amazon for a buck. That's what I use with my AT&T service, and activated it easily online via their website.

I'm not going to publicly bash Ubifi here (I started out with them, and eventually canceled them), but you can do much better, and not have to buy a Mofi 4500.

Sending you a PM.

I have read all the antenna threads here. Am I correct in to believe dual Yagi style antenna seem to be the winner once dialed in correctly.


It's very highly dependent upon a lot of variables. For example.

1. What bands are available in your area?

2. What is the terrain / foliage like around ...

Thanks for the info. I'm going to set it up soon, and do a full write up on how to do this.

I'm probably going to get one of those AC measuring devices, as I need one anyways. I'll take some measurements of the PI with a few modems and see what happens.

Thought I'd start a thread to discuss WISPs. I think a lot of folks that are technical and setting up 4G conections are probably learning about WISPs in the process. They are very common in rural areas now to solve the rural broadband problem.

Part of my adventure into 4G as a home internet ...

And it defaulted to MBIM,but running the commands for qmi again were successful after the reset.

Nice detective work, and thanks for sharing!

I realized that difference after I posted about it.

So you were able to fix it?

https://remote.it/ is a good option if that OS on your router is supported.

It setups a reverse tunnel, so you don't have to worry about ports being blocked inbound.

Very interesting results indeed. Very surprised that the yagi was less effective than the panel antenna. I've sent an email to Jim to ask for the azimuth for those panel antennas, since there isn't much information available for them out there. Typical panel antennas that size can't get better ...

FYI the EM7565 has a firmware bug that shows the main signal stats on B66 to be weaker than they really are. I noticed that in a couple of your screenshots. It's not an actual problem.

Thanks. I'm getting very consistent speeds with the current setup. I'll average 50-60dl/25-30up during congestion times and when it's not congested it'll give me the faster band 2 that pulls 100-130dl/35-40up. It's operating in QMI since that's how it came. You think switching to MBIM would help ...

Very nice setup! Thanks for sharing.

B2(15mhz) with b66(10mhz)on 2nd and 3rd CA is what gives me the really high speed. Seems it only gives me this cell in mid afternoon or early morning when the network is not congested. When it switches cells on me it's just b66 alone. Speeds average 70/25 on just b66. I might play around with the ...

JimHelms wrote: Mon Sep 02, 2019 6:34 pm One of your biggest limitations is that the WE826-T2 LAN/WAN is only 100M...as opposed to 1000m (or GB).

This is your issue. I'm surprised you can even get 92mbps down. I see normally about 86mbps limit on a 100megabit network card.

Hello swwifty,
Believe I just read a post that said you would mostly recommend wide band antennas? Apposed to Yagi Band specific ones? Asking to see if you are still using your Yagi Band 2 antennas as your set up? Very much considering doing the set up like you had from this post. Would you still ...

LateParrot wrote: Thu Sep 26, 2019 9:08 pm Ah so you're just setting up QOS on the one AP right? That's pretty clever as long as they don't know there are other SSID's.

Correct, well it doesn't matter if the other SSIDs are visible or not if they don't have the password

Below is a detailed review and comparison of a bunch of antennas.

A little back story: During my adventures into 4G/LTE, and learning about the technology, I found it really really fascinating to test different antennas and configurations, and many of them in different locations. These types of ...

you're welcome, glad it was useful to you!

Quick question:

"Location: My home, in the North East GA Mountains For reference, below is a screenshot"

Could you share what software / website you used to create the the screenshot that mapped the terrain? Looks very useful...

Thanks!


I used the Radio Mobile Website to do it: https://www ...

Thanks @swwifty! Have looked at the PI and they look firm. Maybe sometime you could create a thread with good description of hardware, bet others would find it useful and informative (like your antenna comparison).


Yeah I could do that pretty soon, but its really easy.

terryjett wrote: Mon Nov 11, 2019 3:31 pm Any others using the AT&T iPad no contact plan with non-at&t hotspots?

That's what I was using, not sure if I made that clear or not earlier.

I'm not sure what you mean by signal booster when talking about the various Sierra modems? I assume you mean for cell service? If so, you can just use wifi calling, once you get a better 4G setup for your internet.

If you are going to use AT&T I'd recommend spending the extra 50 bucks and getting ...

Maybe they meant a 100x increase in signal strength? That would be 20dbm, which I think could be possible.

Like I said before, forget the signal booster and just setup a connection for your internet, and use wifi calling.

The problem with high gain antennas is they are very directional. If you don ...

If you are really serious about your network, then I would highly recommend running separate dedicated access point(s) and a dedicated router/4G modem.

All modern 802.11 wifi standards have MIMO, and the latest use beamforming. Beamforming is dependent upon the client as well, and most don't ...

terryjett wrote: Sat Nov 16, 2019 9:11 am I assume you're talking about sim cards

My bad, did not make that clear. Meant what model modem card(s) have you used with success on AT&T plan.

oh, then in that case I've used the MC7455 and EM7565 with AT&T no issues.

Swwifty my friend, you are more helpful than you know and your build has helped quite a bit with other questions I might have had. Your testing with the panel antennas was also quite enlightening. I'm assuming my best bet is to just test with the antennas I get and see what bands I pick up with ...

CA is entirely controlled by the carrier, but you can limit your modem to only certain bands, but if they aren't available on the tower side theres nothing you can do about that.

Also here is a antenna review I did a while ago, but is still very relevant. viewtopic.php?f=24&t=251

One thing I just realized is the Band 4 downlink frequency you are connected to is 2350mhz (I looked this up here: http://www.rfwireless-world.com/calculators/LTE-EARFCN-frequency-converter-calculator.html by putting in the LTE rx chan, FYI normally it doesn't come out the same number) is really ...

I have discovered that the wireless output of the router is usually significantly less than the LAN ports. I took the unit up to the building where I want to use it and with the right placement the wired connection would consistently be around 25 mbps download. Wireless internet would anywhere ...

The problem with signals at longer distances, it can vary with the air's ionization, humidity, clouds, rain, snow, blooming trees, etc. So just because you may get a great signal on a nice clear summer day, you could also get really crappy signal on a humid rainy/snowy day. Generally, a high ...

I dont believe that it matters which end is on top, so likely keep the weep holes facing down. I believe the the angles used are an attempt to match the plane of the carrier equipment of the tower your using. Common practice seems to be 45 degrees from vertical plane. One tilted "left", the other ...

I have two of these yagis installed at 45 degrees to each other and they are hooked up to a MR 1100 Nighthawk. They are about 12 ft. up on the pole and I am 1.4 miles from the tower.

oh that's pretty slick, but a USB enclosure is still cheaper.

Granted if you're tight on space, that's not a bad idea.

It's very common on the outskirts of san antonio area. Kinda of a monopoly for us. Vtx took over rock solid from my sources. Crowded network makes it's difficult to use. If only I can find a card that would support the AWS band to take full advantage of lte, but using mofi I still dont think it ...

I wanted to do a complete post on my setup with context, and technical details on what I did. I'll start by giving some context on the why.

Last year I moved to the Northeast GA mountains. I work as a Systems Engineer, and work full time remote. Thus, as part of this move, fast and reliable ...

I'd recommend using the Raspberry PI foundation PoE hat. The latest version, the first versions had some bad bugs.

I found this recently while doing some more research and learning on reference signals in LTE. I highly recommend watching it, and downloading the spreadsheet in the description and playing with it. This will help you understand what these values mean, and how they related to each other. I've been ...

I am about to begin the journey of setting up my own installation and had a few questions for you:

1. Did you terminate all the cables yourself to get the minimum possible length?
2. Why did you go from LMR-200 to LMR-400 instead of just using LMR-400 for everything?
3. Can you explain how the ...

Very excited to see what updates you have in store. I very much look at your project as an inspiration for what is possible. Now that I've had a taste of real high speed internet out in the mountains, I can't help but want more! :D

I posted a more specific thread yesterday and received some ...

Thought I'd post with some interesting updates.

It dawned on me the other day, that I could probably come up with a test, so to speak for my multipath issues I've been having. My theory was to unlock my modem from band 2 (let it connect to any band), and see if the other bands (I knew this would be ...

Interesting results, this is still using the yagis? I'm surprised that they can perform so well on channel 12. So regarding the multipath issue, are you just going to leave it unlocked or are you going to try to continue experimenting with other solutions?


This was using the yagis. I was ...

@Swwifty

Just recently ordered a setup to match what you have here, except i ordered the panel antennas instead of the yagi's. I currently have a Mofi4500 w/ AT&T sim, and while speeds are decent, after seeing your setup, i realized that there was much more to be had. I also ordered the EM7511 as ...

Apparently i've got some more research to do. So here is what i'm trying to accomplish so maybe you can point me in the right direction.

I want to be able to hard wire a few items in (couple of playstations and a PC), but also be able to have wireless access for phones, ipads, apple tv, etc ...

Any recommendations on a switch?


Depends on how many ports you need but this is a good place to start: https://www.ui.com/unifi-switching/unifi-switch-8/

Also has PoE, but you'll need an adapter for 24v PoE.

Or you could just go with this switch which does all PoE modes: https://www.ui.com ...

That's a good start. I don't see anything obviously wrong or missed.
