We are excited to announce that we have launched our new Hive Community! HiveNation will remain as an archive, but all new posts, discussions, and articles will be created on Hive Community. You can visit our new community at thehivecommunity.aerohive.com
The first wave of 802.11ac gives you a bit more than double the performance (80 MHz channels plus 256-QAM). In cases where there is very high client density, that may support upgrading from high-end 11n to 11ac. One common use of 802.11ac is to support areas where users tend to cluster together. It's not being used yet as the technology to blanket an entire building, but that will come.
