So, I'm fairly savy when it comes to making these links in the link planner software and one link in particular seems to have me confused. When I replace a link I've made with PTP 650 gear with 3 foot dishes at each end with a ePMP 100 PTP link with it's default setup on the exact same frequency and heights I get much better results with the lower priced ePMP gear. I realize the 650 is a better piece of hardware with lower latency and more engineering but, I mean, when I get 20 meg more in expected throughput and the price difference is at such extremes I don't know if I can ever justify the 650 unless this is just a bug in the link planner software.
So, my question is: Is this normal? Does the ePMP PTP outperform the PTP 650 in raw throughput performance even with larger dishes at both ends on the 650?
