I finally got my outdoor antenna mount setup, and did a final test on the roof. The results actually surprised me. 17dbi gain yagis signal strength Screen Shot 2018-10-18 at 12.36.03 PM.png Speed test Screen Shot 2018-10-18 at 12.38.07 PM.png Now compared to the flat panels locked to band 2.

Based on the screenshots you shared, it looks like your modem is connecting at times to Band 17 and Band 4. You are likely on the outer edge of a cell, and that is why its hopping back and forth between those bands. I did some research on that Sierra modem you have, and I can't tell if it supports c...

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" you...

This is an interesting paper on Cell Load and RSRQ.

Thanks for the suggestion. I’ll double check the channels in use. I have an app on my tablet that will do that. However, I’ve used other Asus and Netgear routers in the same setting without issue. I could see reduced throughout due to congestion on channels, but failure to be able to ping the route...

That's really odd. I used to have a Mofi 4500, and I experienced similar issues. I never was able to resolve them though. Are you positive you don't have any interference on 2.4ghz? I would check the channel and make sure with whatever tools you have available. You'd be surprised even living in a ru...

Now, here's the 15dbi flat panel locked to band 2. (also on the high 10 foot pole) Screen Shot 2018-10-11 at 5.57.23 PM.png Keep in mind here that SINR looks better on this, but this was just a snapshot. It was fluctuating between about 11-14, the same with the Yagis. Screen Shot 2018-10-11 at 5.57....

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 an...

I recently went to a really high state park near my house with clear LOS to a lot of cell towers. Out of curosity, I took my PI setup with modem to see what LTE signals I'd pick up. The results were somewhat surprising. Screen Shot 2018-10-12 at 5.53.35 PM.png Check out all that interference from al...

Thanks for the info! Any chance of the same for the DP1727X15? https://thewirelesshaven.com/shop/antennas/1700-2700mhz-15dbi-4g-lte-mimo-directional-antenna/ I'm curious how their performance compares at the higher frequencies. I would guess its basically the same. The higher up in frequency you go...

Here are a few specs on the 15dBi antenna. 15dBi 3.pdf Thanks for sharing! That's what I suspected actually, that the advertised gain was on the highest frequency that the antenna was rated for. Regardless, this is still a very good antenna, even in a non-light of sight environment. On band 2, its ...

Doing some more research, and found this: https://www.minicircuits.com/WebStore/d ... -1940-S%2B which is a band pass filter, for band 2 range, but might try and find a high pass filter, so I can still use CA.

Looking forward to that information Jim! Yes, I agree, lots of trial and error helps, and teaches a lot. This morning I was doing some thinking as related to my posted I just shared about reference signals (see that in the off-topic section). I recently purchased some of these (https://www.rfarmor.c...

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 wi...

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 t...

great post, thanks for sharing!

Hmm interesting thought process. Seems plausible from a surface level observation. I have no idea how one would be able to show that in a test but that would explain the signal strength similarities between the two. Just wait till you see a pic of the sector antenna I installed on Sunday, it's 15 D...

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 than...

Sorry for the delay getting this posted up, been really busy the last few days. I've already posted the results of the 3dbi omnis vs. 15 dbi flat panel vs. 17 dbi yagis (with their respective appropriate bands). I won't post them again, but wanted to share a few other interesting scenarios I tested....

Update: ran a ton of tests yesterday, full report coming soon Unfortunately, I don't have time this weekend to do a full write up (It's gonna be long), but wanted to give some spoilers :) Short story, the DP727L15 is a great antenna across the wideband of frequencies it covers. Band 2 at my house j...

Got the band 2 yagis today, comprehensive test results coming soon

oh, that info is good, but is that an app on your phone that connects to your router/modem to view info? I've never seen those screenshots before much less on GoldenOrb. If you login to the router interface from your computer, you will go to Modem -> Misc -> AT-Command and type 'at!gstatus?' like in...

is that the signal strength on your phone, or the WE826 router? Also, what operating system are you running on it? I highly recommend installing GoldenOrb, if its not running that already. Reason I ask, is it has a lot more detailed info available in it. From what I can gather, that doesn't look lik...

Great info and observations! I completely agree about SNR/SINR, with LTE it is a very very important aspect of the process. Below is a couple of websites further digging into SINR and its relation to high frequency signals (2.4ghz and higher) and general LTE frequencies also. [url]http://www.wirele...

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.

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 som...

Can the remote.it service be utilized on devices other than a pi? I signed up but don't see how I can use it with the setup I'm working with, or maybe it's outside my skill set. Also, this thread is making me wish I could actively tinker with this stuff, very nice results! I believe it can be, but ...

No worries on the confusion, you have been very clear so far and I have followed your train of thought on the two different locations throughout the experimentation process. My question was specifically on if you decided to mount the system in that remote area how you were gonna get the internet ba...

Dude those band 2 speed tests are super sweet. The best band 2 speeds I got were on a tower down the road from my house. I'll post the speed test results here from that test. https://imgur.com/a/y8LVoKZ Question: how are you going to run the internet connection back to your house? Very interested i...

Another update, climbed to the top of my mountain with these antennas I'm off this week, so I'm trying to constantly stall my property chores :lol: Anyways, i had previously tested my omni antennas up at the top of the mountain that is behind my house (about 200 feet higher or so). I wanted to try ...

Thanks for the update! Great info and conversation. I am going to throw even more options at you that I have experimented with lately lol. Make your primary antenna a band 2 specific antenna and then your secondary antenna a multi band antenna (use one of the 15 DB ones you already have). I have a ...

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 band...

Ya I'll definitely go with a 700-2700mhz antenna. They're on AT&T. Although strangely enough when I was there band 30 seemed to be the only band that performed well at all. Which is counter intuitive since it's a higher frequency (2300mhz). Band 2,4,12 all performed at generally less than 3mbps...

Oh good point! I somehow missed the differing frequencies between the two antennas. I definitely see the incentive now to keep the antenna cables as short as possible. I initially had no clue why people were mounting equipment outside if they didn't have to haha. I'm fortunate enough to have fiber ...

Thanks for the link that helped even though most of it was over my head. I guess I'm just curious how a two antenna setup like yours would compare to one of these: https://thewirelesshaven.com/shop/antennas/1700-2700mhz-15dbi-4g-lte-mimo-directional-antenna/ Does having two antenna double the gain ...

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 test...

Wow, not bad considering the terrain. How far away from the tower are you. I see a reference to "9 m" but uncertain what the number is. I'm 5 miles from the tower. The tower height is 358ft AGL, and my UE is at about 30 feet AGL. It is surprising given the terrain, the fresnel zone is cut...

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'l...

As long as you don't lock bands on your modem, you should get CA (assuming its available in your area.)
