I've been using UBNT stuff for a while now and like all you guys already know.. its great.

We want to replace our Tranzeo Full Duplex 5.8Ghz link that is maxing out at ~20Mbps.

Im trying to understand what we would need to get to have a 100Mbps+ real throughput link ( less than 2 miles, clear LOS).

Do I buy all the UBNT pieces that I need and put them together to make the radio?

Here's what I'm thinking to get, please chime in if im doing something wrong.
(Per Side)
1)SR71-15 MIMO card
2)LiteStation SR71 board
3)Outdoor Enclosure w/ 2 antenna ports (to pigtails..)
4)PoE... have to find the correct voltage requirements..
5)2x antennnas - panels or small dishes (hyperlink or PacWireless maybe).

Is this it? I will use the AirOS software that already comes with the equipment, right? Basically set up the config similiar to how I use the Nanostations and Powerstations? I would love to know how to determine how far apart to mount the antennas from each other and which antenna would be the best to use.

Any help you guys have would be appreciated. If this works the way that im guessing, I would be ordering this equipment ASAP.

Is all of the UBNT equipment that I listed available from the resellers?

Thanks in advance.

My guess is that most have come to realise thing's arn't perfect...

I, like many other's, have been waiting month's for "my software guy's" to figure out why we are all getting 30 millisecond pings from the AirOS on the Litestations when Aggregate is checked.

Surely you could purchase the UBNT gear to "achieve" the speeds some are getting, but with this also comes the downsides. I call this the "learning curve", in case anyone needs a name for such.

My next question would be how much packetloss are you willing to sacrifice for such speeds... This also falls under the "Learning Curve" as named above, and will simply take time to find a happy medium for you, your tech's, and your customers...
