Either of those may work equally well from a speed perspective, for band 12, but it did seem like the Eastwood had a stronger signal. Maybe the ones with the poor adapters would work better with other adapters too.easternnc4me wrote: ↑Fri Jun 14, 2019 4:27 pmJust tried it in 5 different locations. One of them was outside on the second story balcony of my sisters house (she lives behind me). Tried between her house and mine, my back yard, front yard and beside the house. Same result with all of them. Band 12. At least I know to use the Eastwood antenna instead of the Netgear.
Here is something else you can try. See if you can run an AT!LTEINFO? (doesn't need to be all caps, just typing it that way to avoid confusion with the L and I) command. I don't know if that will work with that modem or not. Run it during a speed test.
First off, that would be a fine choice, as would this one: https://ltefix.com/shop/antennas/4g-lte ... l-antenna/. The yagi may be more cost effective for you, given that this is a backup internet system.easternnc4me wrote: ↑Fri Jun 14, 2019 4:27 pmWill using ONE yagi directional antenna improve speeds?I understand I would have to locate the best cell tower that might be further away. Again, this will not be my permanent internet. More of a back up and for use on vacations. But if it will improve speeds I can make a short stand to mount it on to use it inside. Something like this: https://ltefix.com/shop/antennas/4g-lte ... l-antenna/
Having said that, that is a difficult question to answer without more data. If you can find out the physical location of the tower that you are connected to now and drive closer to it with your setup in the car with you (powered off an inverter), then you could see if there are more bands available on that tower. You could even try it with your phone. You won't be able to see the carrier aggregation bands, but you can see the speed and if the speed jumps up, then you might be getting other bands. There are apps you can run that will tell you which tower you are connected to, so you can be sure the speed difference isn't due to connecting to another tower.
If you are able to determine that the tower in question has more bands, then you might be able to get those bands with a directional antenna, since the antenna will focus its power in a smaller area instead of spreading it out 360 degrees like the omnis.
*If* that ends up being true and you pick up other bands from that particular tower on the directional antenna, but can't pick up those bands on the omni antennas at your house, then using a single directional antenna will partly help your speeds, but not as much as having 2 directional antennas. The reason is that when you use 2 antennas, the modem can do what is called MIMO (multiple in, multiple out). That means it can send and receive multiple streams of data on the same frequencies on the same antennas. In this case, since you have 2 antennas, then you can double your speed vs one antenna. On Band 12, you would be able to have MIMO with the directional antenna and one of the omni antennas. However, on the other bands, that only the directional antenna can see, you would get half the possible speed. So it would give you a boost, but not boost you as much as 2 directional antennas would.
The other thing a directional antenna may do is to let you connect to a tower with a slightly weaker signal, but that has more bands available. In that case, it is *possible* that the omni antennas can pick up those other bands on the other towers, and you'll get MIMO on the other bands too. If the omnis can't hear the other bands on the other towers, then it will be the same as above, where you'll get MIMO on Band 12 and non-MIMO on the other bands. However, the other tower might have more bandwidth on band 12 too (15 or 20 MHz), so that could be another benefit of switching to another tower with a directional antenna.
Since we got into the topic of MIMO, there is one other special thing about your Nighthawk M1. Technically, it supports 4x4 MIMO. When I say it supports it, I mean the hardware and software inside supports it. Netgear doesn't support it for external antennas. They haven't given you connections on the case to the other 2 internal antennas. I believe when you connect external antennas, it switches to 2x2 MIMO and doesn't use the 2 extra internal antennas anymore (I could be wrong on that). In theory, you could have been getting 4x4 MIMO with no external antennas attached, but the signals were so weak that you weren't seeing good speeds. However, another high possibility is that the tower in question doesn't support 4x4 MIMO on Band 12. I'm not even sure if AT&T does MIMO on Band 12 anywhere. Both the tower and the modem have to support it.
If you can get a Band 30, that is most likely 4x4 MIMO enabled on the tower. Same for Band 14. Band 2 and 4 might be as well, but my understanding is that roll-out of that is behind Band 30. You will only get Band 14 if you have an M1 with model number: MR1100-2A1NAS. If you have MR1100-1A1NAS or MR1100-100NAS, you will not be able to get Band 14, even if the tower has it. Here are all the possible bands you can get if you have the newer Nighthawk. Not all of these are AT&T bands, however.
1, 2, 3, 4, 5, 7, 12, 14, 20, 29, 30, 46 and 66
I believe AT&T supports the following bands (not on all towers and all geographic locations though):
2, 4, 5, 12, 14, 17, 29, 30, 40, 66 (12 and 17 are treated as the same band, and Band 46 is included if you are counting LAA too)
I'm guessing, if you were ever in a situation where you can get band 46 via LAA, the M1 would pick it up on the wifi antennas. That's just a guess, however. And I have no idea what that would do to MIMO capabilities. It is mostly a moot point, since you'd need to be very close to the transmitter to get LAA.
Now, in order to get 4x4 MIMO on the M1, with external antennas, you would have to open the case and void the warranty, if you have one. Technically, you could use omni antennas for the 3rd and 4th antennas *if* you can connect to another tower with a directional antenna and *if* the other antennas can hear the signal from any bands on which the tower supports 4x4 MIMO. No idea if the modem will do 4x4 MIMO on secondary bands if the primary band doesn't support it. There may be some limitation there. If that were the case, you could block band 12 and get faster speeds, *if* the extra bands total more than 10 MHz and/or are less congested than 12.
4x4 MIMO and 4 carrier aggregation are the reasons people like the M1 and are able to get extra fast speeds, assuming they are close enough to pick up the extra bands on the internal antennas or have installed 4 external antennas.
So, to recap, the ways to get more speed, for the M1 in particular, and with your location are:
1) Use 1 or 2 directional antenna to get more bands from the tower you are connecting to now.
2) Use 1 or 2 directional antennas to get more bands from another tower.
3) Use 4 external antennas (probably with at least one of them being directional) to get 4x4 MIMO. It will only help on those bands where 4x4 MIMO is enabled on the tower.
As you can see, there are a lot of variables!
