Re: 802.11N and antennas

My personal opinion.

However, my opinion is based on usage of the actual product. I use them in production links. Others are having similar experiences to me as well.

I believe MT staff would probably agree, but i wont speak for them, i'll let them chime in! :)

Using MPLS with VPLS Tunneling will help cpu usage on the units, but you wont reach max speed w/ tcp on a SXT.....

Re: how many clients on rb433ah

Your real limitation will come down to the fact that none of your UBNT Gear is compatible with protocols where mikrotik can shine in PTMP. For example, Nstreme or Nv2. You are limited to 802.11, which will severely impact the number of clients you will be able to properly service.
