We are currently running a set of PtP 550 as a Backhaul to a mission critical site. They run very well but the throughput is starting to bottleneck. Link distance is 35.5km so 80 Mhz Channels are unfortunately not going to work.
I would like to upgrade this link, licensed or unlicensed, and would appreciate any suggestions regarding which radio model would be suitable.
I would seriously consider 4600c and demote current ptp550 to a backup also, I would look at redirecting low-priority traffic through the slow ptp550, such as Microsoft patches, youtube videos etc, of course this needs to be achieved by other intelligent tools/means in the infrastructure, not through Cambium radios themselves.
Why 4600c ?
if someone doesn’t like the idea of non-licensed 4600c to be the main link, yeah, buy anything licensed and make 4600c backup. Because this is mission critical site, it really deserves some backup nonetheless.
