Latency vs. Usage
If they run Xohm like Clearwire, it will get oversubscribed between 3PM-10PM when the highest amount of subs come online. Latency will go up.
Another thing, try testing Xohm when there are more subs on at the same time. It would be interesting to see how they are aggregating the links to their backhaul.
Xohm had mentioned they were having problems finding backhaul at prices within their business model, so where did they cut corners?
There is much more to flesh out on Xohm performance.
