Impacts and Recommendations

  • In 2015, WLAN vendors will be releasing and promoting new 802.11ac Wave 2-capable products that will tout massive improvements in WLAN speeds and capacity, but network decision makers should be wary of the hype
  • Wave 2's increased capacity has a cascading impact on the wired switching infrastructure that network decision makers must plan for
  • Wave 2 includes improved high-density WLAN capability via multiuser multiple input/multiple output (MU-MIMO) technology, which network architects can use to support highly transition-dense environments
