    More expensive

    All of your other modems only Transmit on the main port anyway. 2x1 MiMo no matter the frequency. The LM960 is 4x2. 4 downlink and 2 uplink on 1.7GHz and above and 2x1 on low band no matter which is your main component carrier in the aggregation scheme.

    Say you are on bands 2/4/5 with 2 as Primary and 4/5 as secondary. You would get 4x2 on band 2, then 2x0 on band 4, 2x0 on band 5. If you are on band 5/4/2 Then you will get 2x1 on band 5, 2x0 on band 4 and 2x0 on band 2. Does this make sense?

    Sierra Wireless EM7511, Sierra Wireless  EM7565, and Telit LM960), which modem is the best? 

    In exactly that order least to most.

    Anything you recommend that I do different?

    Hook up all four ports and it will fly on 1.7GHz and above. 4x2 MiMo and all

    I am curious if there is a newer hardware version and newer firmware version for this modem.

    There is the 1000 model, and the A18 model. The only difference is A18 currently comes with 4x4 MiMo on the second carrier as well, but it is interband only e.g. Band 41+41, Band 2+2, Band 25+25. I believe only engineering samples are out. The 1000 model will get this as well. Telit has not updated the firmware since it came out last year.

    In addition, do I need to make any configuration change on the modem via the AT commands? 

    Only if you want a specific frequency or set of frequencies. Other wise the network will place you where it wants.

    Any comments on the design I posted with the Pepwave unit? 

    I am not familiar with the Pepwave, but updating the radio is a good start. Look for deals to update your other one I suppose. I can't say enough positive about 4x4 MiMo on midband given the right environment. I will look at your hardware more today and see if I can offer you any input. Radios are kind of flux right now since we are peaking on LTE, I am working on getting some 5G radios from China as soon as that place stops exploding with virus, they would come with a Cat 22 LTE radio underneath the 5G New Radio radio.

    Any of the radios from Telit like the LM960 and up are going to be good, their FN980 is just now getting to engineering samples being dispersed. The upcoming EM20 from Quectel is going to be pretty sweet. I have been building out a lot of those lately with the engineering version, a fren has a peak speed of close to 385Mb p/s using Sprint with one sitting in an ZBT WG3526 router, over PoE. 4x MiMo and 3 carrier aggregation.

    I thought your final design was the H721 unit

    My great works never finish. I also have a few of those going.

    In addition what xpol antenna did you use?

    XPOL-2-5G Poynting Antenna

    This is just like the previous Poynting except they added 3GHz support. Good antenna to catch C-band's lower channels with, such as CBRS.

    So what was your final design? 

    I've been through two sets of LM960/CBA850 since this. First one was for a family member and another sold to a fren. They work great via PoE to an NEMA rated outdoor box. I used a pair of -15 dB xpol antenna tuned to 1.7-2.7GHz, LMR400 coax, assorted cable mounts and plungers for the plumbing to keep everything tight through wind and rain.

    It's definitely on a tower by tower basis. My parents are using an unlimited iPad SIM in an LTE modem (depriorized after 22 GB), and they usually push 250 GB/month on it. On just the B2 carrier, no CA (I'll see 2+12 CA right after it connects to the network, but then it drops 12 and never comes back). They consistently get 20 Mbps, and up to 30 at off peak hours. But they're also on a rural tower with light load (tower is still only B2 and 12).

    For the three or so years we have been hearing them speak of band 30, then one touch upgrades and now Firstnet there sure is a lot of that exact 2/12 only combo on their network in large swaths. Slow rollouts are not exclusive to Sprint.

    A friend and I are building a pair of Cat. 20 routers. He has Sprint service to test, here are his results with a macronode that tops at 3x aggregation, 4x2 MiMo, about a mile from his site.

    He is using 1 dual port -19 dB gain antenna tuned 2.4-2.7GHz and 1 dual port -15 dB gain antenna for 2.4-2.7GHz to match 4x2 MiMo. We are using Quectel Cat 20 M.2 embedded radios and LMR400 coax. It is mounted 35 feet in the air. PoE. The ping sucks because we are working on making QMI stable in certain router builds so MBIM.

    Bruh are you telling me I should have just skipped all this and bought an inseego?

    Since November it has stopped reporting correctly on my T-Mobile Potatorola E5+ and Pixel 3a.

    The app has never let me log in to my account for some reason, I tried all the usual thing user @mdob07 mentioned. Before this time it would still report and I could view progress on the browser later at home. Now it puts few points up and disregards changing reporting times. I have kept it screened on and kept other mapping apps open at times to see if this made reporting better but I stopped using it. 

    Now it is just another signal app and viewing on chrome desktop is pretty broken.

    I, too, am a new customer of SardisTel. Yes they SUCK! The absolute WORST customer service I have ever experienced. I do not see them staying in business very long the way they treat their customers. My first attempt at getting some assistance through the online portal was, of course, for speed issues. I followed their requirements when submitting the ticket and received a one size fits all speed problem reply (interference around the house, etc.), and then they closed the ticket out. I sent two more replies, as this is supposed to re-open the ticket, but never received a response. Then I screwed up and called them! The guy was extremely rude, and the first thing out of his mouth when I said I was a customer was, "You must use the online portal." I was not rude, but the guy just hung up on me. So I called back and asked if he had hung up on me, and he said, "Yes I sure did! Have a nice day". Click, he hung up again. So I sent another reply explaining my dissatisfaction with his service. A few days later the entire ticket was removed from the system. So, I submitted a new ticket explaining all of the speed issues, and have yet to receive a reply back. I will be cancelling the service this weekend and I will have to lose all that money for less than 3 weeks of service. I think I will try the RVitGUY.com

    Get an AT&T iPad plan, insert the provisioned SIM after buying a Nighthawk or building an LTE router, avoid middle men and save money.
