802.11ac (VHT) - Just the Facts
When a new development comes along, related to any technology, the proper foundation must exist if we are to understand it well. Today, I want to present the basic facts related to the new 802.11ac draft amendment of the 802.11-2012 standard. The purpose is to answer the five most common questions asked about 802.11ac:
- Why create a new physical layer (PHY)?
- In what frequency band will the PHY operate?
- What new capabilities or technologies are introduced?
- Who will benefit from it?
- When will we see it?
One of my human resolutions is to be more optimistic and to find more opportunities to speak words of affirmation. I know, that seems better suited to a pop-psychology Christian blog than a WLAN blog, but bear with me for minute. Words of affirmation are sometimes rare in technology realms because if we’re really honest, most IT folks are surly, irascible, and unwilling to say nice things or help junior engineers. That’s a pretty crummy way to spend your days. And that’s why I’m often inspired, encouraged, and even surprised when I meet skilled senior engineers that are willing to be human by graciously recognizing that everyone has to start somewhere.
