+1 on all counts.
My experience with LTE CPE wasn't a lot better. If you point out any
shortcoming in the CPE, Telrad just pointed their finger at Gemtek (and
whoever made the 8000). I could choke their throats all day long, but
allegedly they couldn't do anything about it. I wouldn't mind buying a
Cambium (or Ubiquiti) LTE CPE because at least I know who to complaint at.

When we dipped our toe in the WiMAX pool (Purewave, not Cambium) one
of the things I didn’t like was everyone wanted to sell basestations
and rely on the WiMAX “ecosystem” to supply CPEs. And those CPEs
(like Greenpacket) were wimpy little things with low xmt power, small
low gain antennas, and limited feature set. I forget who the OEM was
for Mercury’s CPEs, they were cute and a little better on the feature
set, but still not much power or antenna gain.
So it is good to see Cambium developing their own CPE, both 3 GHz 450,
and cnRanger. And not making them wimpy little things.

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.

understand that tradeoff because I've had to make it myself.

require a completely different SM.
