What are the benefits of fixed ratio over flexible?

You should read up on how GPS sync works and if it’s right for you. Here are a couple of Cambium resources to get you started:

ePMP GPS Synchronization

by Luis Mendez Why GPS Synchronization? Briefly, GPS Synchronization will minimize interference generated by the system onto itself, making AP collocation and frequency reuse feasible. A stable timing source is utilized by every AP in the system to precisely synchronize the start of every transmit and receive cycle within the TDD framing structure used in the Cambium Networks ePMP solution. Figure 1 depicts two APs in GPS Synchronization mode while Figure 2 shows worst possible scenario for …
