We have 8 of these links in place now from 2.87 km line of sight, to 20.4 km near line of sight. Tecnically, they work really well. We haven't had any real issues other than some management based details.
- ithey needalignment tone available on both Master and Slave. When would you not have to align a Master? At one point, the PTP100 radios had this, and it disappeared in later releases, drives us nuts. The Orthogon based stuff has always had alignment tone on both ends, why don't the "latest and greatest"?
- the OID for the physical interface status seems to be messed up in some firmwares and not others. 13.4 it was broken, 14.0 it was fixed, 14.1.1 is broken. Again, the "latest and greatest" firmware release broke something that was fixed in the previous realease. That said, this same issue is in 14.1.1 and the PMP450i access points.
- the hardware is really nice to work with. Small and light, seems rugged enough for harsh environments and rough handling.
- I don't understand why the mounting brackets are not included. Come on, there is only one mounting option, so why not include it? Are there really people that are just hanging these by the handle with zip ties? Duct tape? I could undertsand if there were different options like pole mount, wall mount, seagull mount, etc.
- having standard 802.3af PoE is nice as well so these can be powered directly from our switches. Adding the adapter cable isn't a deal breaker for CMM4 use and is actually nice so we don't need "custom" cable pinouts to the radios (reduces confused techs and incorrect pinouts).
Overall, we're pretty happy with them and their performance. We look forward to some things fixed and added in future software releases.
EDIT - I forgot to mention, that short link, 2.87 km, was the first one we installed, and it has a session uptime of 102 days 16 hours.
