Hmm lots of options... Not sure what your limitations are.. 1) Yes, shorter the distance, better the uptime , less the rain fade. 24ghz or 80ghz or even 60ghz (***)
2) Don't count out the 2.5G Metrolinq with lR Brackets, especially if you are looking at sub 1mile link. 3) you can always be creative and bond, AF24 + 60Ghz links to get desire thru put (secret to using 60ghz is in using the 64.8ghz channel on the current hardware.. very different oxygen absorption characteristics .. rain fade will be very similar to 24ghz).
