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.
