My experience with the PTP820 ranges from very impressed to extremely disappointed. Every single radio in our network is a Cambium Networks radio so when it came time to find the proper licensed backhaul solution we had a brief look at the much cheaper competition and passed to keep the uniformity of the network. Our first 820 link went very smoothly as did the next 3 or 4 afterwards. The units appeared to be bulletproof, we had 100% uptime on them for a year so.... we buy more expecting the same results. But, not so.
I recieved the next batch of them. Lab tested and found 1 DOA. Recieved RMA from vendor. Put that unit up and it has bizarre issues with the ethernet locking up and requiring a manual power cycle. Contacted support -which is a totally seperate rant from this one. Absolutely no help AT ALL. I guess they just assume you haven't already tried troubleshooting things yourself before going to the misery of contacting support for issues. Troubleshooting from support ranged in obvious solutions to completely obvious solutions. Anyone who has called suppport knows exactly what I'm talking about. Oh, did I try firmware? Well jeez, I dunno Mr. Cambium support, would you like me to try the last 3 firmware updates that have been removed from the website or the firmware from a few years ago? It's just a battle to see which side yells "RMA" first.
When you pay a premium for a product you should get a premium product. Since the PTP 820 is the only licensed product in the Cambium portfolio, it looks like our next licensed link purchase will be our first outside of Cambium. If the product and the support are like this, why would I buy another PTP820?
