Wireless operator marketing has left many confused about what the "G" on their smartphone actually means. Now, with 5G looming on the horizon, it's even more important to understand not just how we got to 4G, but what it means for everyday use and Star Wars viewing. (See What 4G for Me? and What We Mean When We Say '4G'.)
Positioning 802.11ac as 5G 4G has been just lately ratified by the ITU under their IMT-Advanced standard. The important cellular carriers here are simply just getting their heads around the best way to deliver an accurate 4G service (pending the release of VoLTE - an all packet network). There's lots of spectulation around what 5G may be / mean but we definitely do not have that technology / service capacity because of the Insufficient Storage Available now.
What is remarkable for Parramatta in this case would function as the start of a network that has been compliant with the 802.11u standard. As an alternative to get excited about the increased rate of 802.11ac (rate without QoS lacks actual relevance in anything over a cheap / free consumer service), we should be looking at the advantages that come with information offload, automatic network authentication, crisis alterting, user traffic segmentation.
