Hello,
Does anyone know of or can anyone recommend LTE equipment vendors that
sell point-to-point or point-to-multipoint radios that are capable of
non line of site (NLOS)? Is LTE even capable, as a protocol, of dealing
with non line of sight?

We chatted about this a little here, we're pretty pessimistic.
1) Any NLOS stuff involving sky bounces (tropo stuff) will likely be killed
by timing issues. This could be resolved through a custom client or enodeb
but there aren't going to be units like this at scale. This could be saying
that LTE can't do NLOS at significant distances.
2) Any NLOS stuff not involving sky bounces is probably just using the
lowest frequency you can for better propagation. While that gear is readily
available (we're using band 8) it's unlikely that meets your use case as
it's mostly just a larger range for the network and not huge distance ptp
nlos.

Hi Peter
I can't tell you about specific equipment, but LOS or NLOS is not
related to protocols. Distance can be related to protocols, but the
presence/absence of obstacles that limit the line-of-sight has influence
only on the link budget and the stability of the link. With higher
frequencies LOS becomes a must, though with lower frequencies
propagation can be good without LOS; if you want NLOS for medium
distances, I guess that you want systems operating in UHF (I think that
there must exist, as I heard some technical people from Telefonica del
Peru talking about LTE in 700 MHz).
Hope this helps
