If you do an iPerf test between devices on either end (no other traffic) you should get close to 150mbps on that link.
The part of the datasheet saying 54mbps that you attached is cutoff before the chart gets to the meat of it. In fact, that screenshot only shows the 802.11a modulation scheme rates. If it's running in 802.11n (or airmax in ubnt terms), which you are, you'll see it going as high as MCS index 15. https://en.wikipedia.org/wiki/IEEE_802.11n-2009#Data_rates The above link has a nice chart that explains what MCS values mean. You'll see that MCS 15 should equate to an "over the air" rate of about 270mbps. Real world throughput it usually just over half of the OTA rate hence 150-ish mbps. It's still a bit of an ideal thing, and small packets tend to kill your real world rate pretty quick, especially on these older M radios that are CPU limited. But hopefully that gives you an idea of where the numbers are coming from. If you replace those radios with their AC brethren, you may need to compensate for the lower TX power and higher SNR requirements to hit the higher modulation rates for that level (ie, bigger dishes, better LOS, etc). You'll also need to be able to move from a 40mhz channel up to an 80mhz channel. If you can't do those things, you'll see about the same real-world throughput as your old radios. Maybe better PPS if the old radios were choking on that. https://en.wikipedia.org/wiki/IEEE_802.11ac Marketing is giving the "ideal, best case" at all times and it's best to drill down into all available documentation for any OEM.
