I guess the answer is in what the definition is of "Real World" :-)
For the record my conservative comment was not meant to be against Ligowave, but specific to Atheros Mini PCi Cards in general, regardless of the software platform. I agree if you can get a peak modulation consistently w/ compression, sure you can get the speed. The Ligo MB hardware has the processing power to do the speed, with multiple cards. However, in my real world, we are lucky to get 18 mbps modulations, allthough when doing 20Mhz channels we always try for 36mbps mod if we can. I'm not possitive, but I think the 10Mhz channel may max out at 27mbps modulation as an option, with Atheros. (Although That should be verified with Ligo, as I may be mistaken). The problem with commercial grade services is that they generally don't respond well to frequent modulation changes. If a modulation is bouncing back and forth from 36 to 18 to 24 to 36, etc, it will have very undesirable effects on the End Users' TCP session throughput. We have found it much more advantageous to hard set the Max modulation to a lower number that would result in the least frequent amount of automatic modulation changes. It doesn't matter how fast the radio can test in peak situations, it matters how fast the end user can push their data consistently. Usually the best we can count on consistently is usually closer to 15mbps, in our environment. We bit ourselves in the Back-side to often quoting 10mbps Full Duplex, and only getting 5 mb on way and 10 mbps the other, and having our customers Claim we didn't deliver our SLA, and having to requote/redefine the job. I'm not saying that people can't get 20mbps, some people here, have just clearly stated that it was possible for them. I just suggest planning for the worst, and being conservative in expectation. With that said my comment is not a complaint. I can get qty 4- 15 mbps links out of that one 533 Ligo Box, with 10mhz channels, which is pretty darn amazing. What I liked about Ligo though is their support. They try hard to please. There software is also very easy to navigate and intuitive. Its a bit slow to navigate (compared to StarOS or MikroTik), due to web interface redraw time between screens, but that's not really a big deal. My units have shown to pretty much be install and leave it units, with very little trouble.
