Is the CBRS power that much higher where a 450 at CBRS power makes up for the 
lack of nLOS capability as compared to LTE on NN? 

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.

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.

You should probably talk to someone at Cambium, unless someone here has already 
done that. 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.

So the 450M is supposed to be LTE upgradable?

Why are you getting rid of 3.65 Cambium in favor of LTE?
