It isn’t fast, but 2.4 can go places higher frequencies cannot (and as a result may be faster). MVMA and Reuben’s deployable nodes are 2.4. That’s why I’d like to see Xenia covered by 2.4 from North, South, West, and East (water tank). But 2.4 only access points are soon to be unobtainium.

Our topology is linking by 2.4 omni overlap. To prevent that, we could replace the high gain/zero down-tilt L-Coms, lower the height, and perhaps reduce power… but not only can we not afford new equipment and climbing, but it makes no sense to put new antennas on old Bullets. A probably workable technique Chuck thought of was to give each omni its own SSID… assuming it links to others with DtD'd directional nodes.

I’m not on board with 3.4 for flooding.

The equipment is at least 40-50% more expensive.

Newbies have to make sure to get the “export only” 3.4 vs 3.65

IMO, 2.4 properly deployed is still king.
