Fundamentals of 802.11ac

May 12, 2012 - 4 Comments

We released our latest in the Fundamentals series earlier this month and it is trending quite well.  The 802.11ac standard sounds like a step backwards alphabetically…but it will soon be an incredible step forward forward for WiFi once it is ratified by the IEEE. Watch this latest fundamentals to get comfortable with the truth. 802.11n is still your best bet for 2012 and into 2013 as we continue to partner on the standards process but the future is bright indeed!

Michael Brown did a nice overview on PC World: Fifth-Generation Wi-Fi Is Coming: Are You Ready for 802.11ac?

Want more? Understanding what Cisco does uniquely with Four Spatial Streams was another one of my wireless favorites recently.

  1. cisco ccnaCisco Certified Network Associate (CCNA) validates the ability to install, configure, operate, and troubleshoot medium-size route and switched networks, including implementation and verification of connections to remote sites in a WAN. CCNA curriculum includes basic mitigation of security threats, introduction to wireless networking concepts and terminology, and performance-based skills. This new curriculum also includes (but is not limited to) the use of these protocols: IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2),VLANs, Ethernet, access control lists (ACLs).

  2. The AP3600 takes one module (e.g. the 11ac module, or the advanced spectrum monitoring module, but not both). If both modules are required, the different modules can be added in a salt’n’pepper manner across an AP deployment.

    Without the advanced spectrum monitoring module yet with the 11ac module, the AP still delivers the full native AP3600 CleanAir feature-set.

  3. If you put in the ac module, do you lose spectrum features?
