That seems consistent with lots of multipathing. I'd recommend reading about it, if you are interested. The topic itself is a very complex and intriguing issue in wireless channels. I have lots of multipath on band 2, but band 12 is not as bad. My multipathing was so bad, antennas 12 inches apart ha...

Your signal stats look to be good enough to get at least 50mbps town.

I'd suspect tower congestion based on your RSRQ values, and my knowledge that Verizon tends to be more overloaded than AT&T even though Verizon has a much wider coverage area typically.

Your testing is very interesting, but also highlights the need for everyone to do their own testing as things can be very different in any situation (even day to day, etc.)

Very interesting information. Please be sure to keep us up to date with your further tests! They are a great asset to this forum. You must be getting some constructive multipath in the opposite direction of the tower, and some destructive multipath in the direction the tower is facing. Quite interes...

Thanks for the paper. I went down the rabbit hole with the firewall on Windows, so I can keep it and any other programs from sending anything during my testing. I still don't get a "0" value for TX Power, but I do get -- more often now, which I assume to be not transmitting. hmm that's st...

Thanks for the feedback, swwifty. I did see a big decrease in performance with one antenna disconnected (from the SMA connector, not from the modem), so I'm pretty sure it is doing spatial multiplexing. Now, how well it is doing it is a good question. I'd have to disconnect from the modem and run a...

If a tower hands off to another one, will the client show the true tower in the stats? I may not have been clear about weaker signals. What I meant is that if I pointed the antennas at a known tower, my RSRP, SINR, etc. were worse than if I pointed 180 degrees away from the tower. And it did this w...

Where did you measure the 17 inches from/to? I was thinking of doing the same thing, but with the shape of these antennas, I didn't know where that would be. The center of each case? The edge? If so, which edge? don't over think it too much, just from the edge. Over 17 inches is okay too, I just wo...

Thank you

That should work but it might need to be a lowercase B?

Swwiffy: I need to figure out how to run AT commands on the MOFI. WhenI do then I can get you the LTEinfo you request. What should it look like? It may ne in another location for the MOFI4500? Yes the the Directional antennas were outside and the OMNIs were inside. That alone would help the signal ...

A few things to note here on your testing. 1. If you have clear LOS to a tower, spatial multiplexing is basically impossible. You want to actually have some obstruction(s) to help separate the signals and hence double your throughput. This is why you might be seeing slower download speeds than expec...

I just got my 15 dBi flat panel antennas today and did some initial testing with them. I observed a similar behavior. There were 2 main towers that I was connecting to and I know for a fact that one is E/SE of here and one is NW of here. So almost opposite directions. I know which tower is which, b...

Did you figure out an optimal distance to separate the 15dbi flat panels for MIMO on AT&T (B2+12)? I see in your pictures that they aren't as close as possible, but are separated a bit. How far do you separate them? Also, in my testing, I get a better signal and throughput with the back of the ...

is this your only gateway for the USG? I'd check to make sure packets are going back out the same interface.

There could be a ton of reasons for this.

Am I understanding you correctly that you had an upload of 100mbs??

broadband is the name of the APN that AT&T uses.

Thank you for the recommendation So I would be better going with Directional Antenna's then with a outside Omni antenna . As long as you have the time and willingness to determine which direction the tower is in relationship to your house, I would say yes to directional antennas. You also need two ...

I'd recommend buying some external antennas, and giving it a shot by testing outside before permanently mounting. It looks like you could benefit from some based on your signal stats. I'd recommend two of these: https://thewirelesshaven.com/shop/antennas/698-2700mhz-yagi-radome-9dbi-11dbi-4g-lte-dir...

Just thought I'd add that more than likely if you shorten this cable, your RSSI values will go from about -88 to about -70 which is almost a 100 times stronger signal.

Usually I try to avoid shooting over top of a metal roof, cause normally metal roofs cause reflections and multipath issues (I've had to deal with this as I have a metal roof as well). That being said, only way to know for sure is to try it. I think based on your other posts you're already getting p...

honestly, that's really good for just little omni antennas.

I wouldn't change it, if it's not broken. An external or bigger antenna isn't going to get you a stronger signal than you already have, based on those signal stats you shared.

what APN are you using? you should use "broadband" for AT&T

Sorry again for the super delayed response. The cable length is FOR SURE the issue here. I suspect that if you get the modem/router closer with some LMR-400 cable, you will see a significant increase in speed. See the attached screenshot of cable losses for RG-6. I would move the modem closer, and n...

I'd experiment with both, and see what happens.

I would set the TTL properly.

Is this test in the same area as with the phone?

Usually carriers require you to have a device that is compatible with their network.

As far as I know though, the MC7455 will work just fine with sprint.

Sorry for the delayed response, super busy right now. Lots of info to digest here, but got a few ideas. 1. If you have literally clear LOS to the tower, why is your signal so weak? I'd expect a much stronger RSSI value, and higher SINR. Are there any obstructions in the way? 2. You might need some b...

I'd recommend reading this thread: https://wirelessjoint.com/viewtopic.php?f=17&t=286 I'll be posting an update soon, cause I just tried this myself, but TL;DR; you really need a pantech usb modem to set this up with first, then move it to your Sierra modem. Verizon DOES NOT support activating S...

Thanks for the thought. I believe I updated the modem firmware a couple months ago, but it's possible there's something newer I guess. Edit: I checked, I think I'm on SWI9X30C_02.30.03.00 002.046_001 which is the latest. Yes, I'm using the small omnis that came with the USB enclosure for the modem....

This is gonna be a tough one, cause it looks like you've done your homework. Are you using external antennas or some small omnis? I'd recommend moving the device around to see if that helps, otherwise I'm not really sure. It seems Sprint has these issues alot unfortunately, but it could be related t...

what are you using now, just the little omnis?

More details are going to be needed to properly troubleshoot.

Can you provide signal stat information, and more details on what antennas you are using along with the carrier?

Thank You for the reply-- At this time I'm using the weboost as it seems to improve speed.????? I had been using the mbr95 for years, with pretty good success, but had read some of the hype of the (power) of the embedded sim card platform. So this is my first attempt at it.

I'd recommend turning that on. That will fix disconnect issues when they happen.

Also, I recommend looking at Jim's modification to the script, to just reset the modem when it gets disconnected, rather than rebooting the whole modem/router.

a few things i'm thinking: 1. can you run a at!gstatus? at command, to get some more signal stats? that will help me make a suggestion. 2. what 5dbi antennas are those you are running? You might be able to swap those for some slightly higher gain ones that are still wide bandwith (700mhz - 2700mhz) ...

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 where ...

Can you clarify a few things? Are you using the weboost to boost the signal to your small antennas? I'm not sure what you are looking to improve? It sounds like your speeds are pretty good?

It looks like its only a single polarization, which means its pretty much useless for 4G/LTE applications. You really want to have two antennas with 4G to use MIMO, not just a single pole (Single pole will work, but you'll get half the download speeds, and no diversity in signal quality). Additional...

do you have any connection monitoring going on?

Ordered myself a Verizon sim with the unlimited plan to test.

Does anyone know what size sim they send? Just realized I might need an adapter.

I would just use the unlimited plan that you already signed up for.

Buying sims on ebay seems risky, especially when you don't need to do that.

You could be getting carrier aggregation in addition to band 4. I don't think LTE discovery shows CA info for some reason. The other option is to get some of those 9-11dbi log periodic antennas. they perform really well, and have a very wide bandwith. I'm not sure what your question is exactly, thou...

I'd try the WE826 first, cause it's cheaper, than if you still have issues, the modem.

wow, very nice tutorial and option for those with this setup!

Thanks for sharing Jim.

If you can get over 100mbps on band 4 alone, I'd probably just try and get some yagis designed specifically for that frequency range.

They could be used on any router/modem combo you wanted, it all depends on what you need inside the house.

that did not work. when I plug power in the red led and a blue led light up immediately (symbol under blue looks like a circle and an ellipse. then about 15 seconds later I get another blue light (looks like the usb symbol). That is it, they just turn on, they do not flash, no other leds come on. a...

You would need some kind of multimeter, and something in b...

Thanks Jim for the detailed screenshot!

It looks like this is a pre-paid month to month plan? Was just looking to test this out for now.

Thanks Jim for the info, but I'm not seeing in the link where the unlimited prepaid verizon plan is? I only see one that is $45 and limited to 15GB?

Is anyone using the new verizon unlimited plan with a Sierra MC7455 modem? I'm wanting to try this setup, but I honestly have no clue how to get a sim, and sign up for the service? Any input would be helpful. Thanks.

I've seen this with the latest version of GoldenOrb. Is that what you're running?

I recall too that some users have to put there modem in QMI or MBIM mode for this to work as well. I have a MC7455 that I run in MBIM mode just fine, but on a older version of GoldenOrb (from last year).

is your power supply providing enough power? Wondering if that EM7576 is causing load issues when you have high throughput.

This seems to be a reoccurring theme for some reason (I've seen with other posts here). I'm not sure if anyone has the answer to this yet though?

that is really bizarre. I wonder if that wifi chipset is just faulty or something.

Can you ping the default gateway from the wireless clients when the internet connection dies?

It looks like your second antenna might not be properly attached, based on how weak the signal stats look (you can see that in the line starting with PCC RxD RSS:). I'd confirm thats its screwed in properly, and that pigtails inside that attach to the modem didn't pop off, or aren't grounding out by...

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 clo...

It looks like you might be connecting to two different cells here. The cell ID is different.

you're using 3 antennas? What modem are you using with your Mofi 4500? I assume the MC7455? That only supports 2 antennas. Can you provide some screenshots of signal stats? I suspect you need to aim your antennas in a different direction. Omni-directional antennas have the benefit of not needing to ...

Signal percentages are based on usually your RSSI values, which don't mean a ton in LTE. What you really want is a good SINR, and strong RSRP values.

I can't recall where in the Mofi to find that, but can you get a screenshot of those stats, or if you know how to run modem commands, run 'at!gstatus?'

I have some questions, cause its not clear to me what your setup is? 1. Is your 4G connection AT&T as well? 2. Can you share your signal stats from the Mofi, or the other device or both?
