Things have been fairly klunky for us as well. We see issues with the sync between the AP and cnMaestro getting broken every once in awhile. Basically, you have to make changes to information and wait for a day before changing again, or it seems to mess things up. Even simple changes like editing the name of the AP cause a complete re-register, which was a surprise to us. Unfortunately the Cambium support group doesn’t know anything about cnMaestro’s CBRS, so there is really no help available that we have been able to find. The support line points us at the RTMs, but not sure that is going to work well. No word from them yet.
The higher transmit power has helped some of our poorer links quite a bit, so that is definitely a plus.

A few bugs in the beta code for the AP’s, nothing really a show stopper. SM upload rate limit when in NAT mode appears to be broken, but works properly in bridge mode. We are seeing AP’s rebooting somewhat randomly on the beta code when NOT running in CBRS - i.e. they have the beta code loaded but are not switched to CBRS operation yet. I don’t think we have seen any crash reboots on the AP’s with beta code that ARE running in CBRS mode though. Grants / SAS / CNMaestro don’t seem to have many issues. Things are still a bit klunky and having to deal with CPAS more often that I would expect is a nuisance but it’s functional.

Obviously LTE at CBRS power would be that much better, but maybe it's a good fit where people need just a little more nLOS capability than 450 provides and the extra power gets that for them. ----- Mike Hammett Intelligent Computing Solutions<http://www.ics-il.com/> [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/ICSIL>[http://www.ics-il.com/images/googleicon.png]<https://plus.google.com/+IntelligentComputingSolutionsDeKalb>[http://www.ics-il.com/images/linkedinicon.png]<https://www.linkedin.com/company/intelligent-computing-solutions>[http://www.ics-il.com/images/twittericon.png]<https://twitter.com/ICSIL> Midwest Internet Exchange<http://www.midwest-ix.com/> [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/mdwestix>[http://www.ics-il.com/images/linkedinicon.png]<https://www.linkedin.com/company/midwest-internet-exchange>[http://www.ics-il.com/images/twittericon.png]<https://twitter.com/mdwestix> The Brothers WISP<http://www.thebrotherswisp.com/> [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/thebrotherswisp>[http://www.ics-il.com/images/youtubeicon.png] <https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg> ________________________________ From: "Matt Mangriotis via AF" <af@af.afmug.com<mailto:af@af.afmug.com>> To: "AnimalFarm Microwave Users Group" <af@af.afmug.com<mailto:af@af.afmug.com>> Cc: "Matt Mangriotis" <matt.mangrio...@cambiumnetworks.com<mailto:matt.mangrio...@cambiumnetworks.com>> Sent: Tuesday, February 25, 2020 3:59:25 PM Subject: Re: [AFMUG] [ External ] Re: Cambium LTE I completely understand your skepticism Ken. However, Cambium did design the 3 GHz 450m with every intention of being able to support a transition to LTE (specifically, as a RRH with cnRanger). The intent is for this device to be a fully capable 8x8 MU-MIMO. Yes, you’ve got that right though, you’ll need new CPE devices and a BBU for each sector. We don’t have a target date when this will be developed yet… right now, we’re focused on getting the cnRanger CBRS 2x2 RRH and High Gain Cat 6 CPE devices out in August! With respect to NLOS coverage, I will agree that 450 is not quite on par with some of the things that LTE brings to the table (regarding range and the ability to maintain the downlink). However, with the increased power limits of CBRS, the 450m does an admirable job. In fact, in comparing equipment cost and performance, I would suggest that the 450 platform outperforms anything out there. That is, it’s less expensive to get bandwidth where it needs to be (at a higher rate, and to more customers). If the customer density can support the cost of cnMedusa, you’re going to be better off from total cost of ownership (both CapEx and OpEx) perspective. The new 3GHz 450b High Gain has 29 dBm Tx Pwr, and a 20 dBi dish integrated antenna… this is pretty impressive for CBRS CPE equipment (most of the high gain/high power LTE stuff I see is only going to be 23 dBm Tx, plus 15 dBi antenna). There are several customers out there that have done these comparisons… hopefully, they can chime in.

There was talk 1-2 years ago about 450m is software defined so maybe they could use it as a remote radio head with their cnRanger LTE BaseBand Unit (BBU). It has been pretty quiet since then, but I haven’t been able to make it to the shows. Without an update directly from the horse’s mouth like Matt at Cambium, or some kind of announcement, I wouldn’t hold my breath. Back in 2018 it was in the realm of “it would be nice”. That’s pretty tentative. Plus you’d still have to buy the BBU and new CPE, so it doesn’t sound like a huge savings anyway, still 2/3 of a forklift upgrade. I mean, if it turned out that the 3 GHz cnRanger RRH was literally a 450m, that would probably be the best case, but how likely do you think that is? This is just my personal speculation, if it’s an important part of a decision you’re making now, you probably need to get hold of your Cambium regional sales manager, or the 450 or cnRanger product manager. If you’re going to WISPAmerica, you can probably do it there.
