What issues did you have with Nera? We were looking to go with them due to the issues we have had with Ceragon. We looked at Dragonwave as well but several things turned us off of them. I don't know of any other big players that can do 200+ mbit with options of 11Ghz, 6Ghz and external antennas (We also use Andrews).
