We have a Cisco AIR-LAP1262N-N-K9 controlled by WLC 55xx running with 3 X 2.4 Ghz external antannae. We are in the process of migrating a subset of the client base to 5 GHz and I was wondering what antanna options are available for the same. Do I just:
1: Buy additional 3x 5Ghz single band antannae and add to the respective port on the 1262 (part number AIR-ANT5135DW-R=)
2: Replace the existing 2.4 Ghz antannae with dual-band antannae (I wasnt able to find any such option for the 12620).
