FYI. Matthew Gast has just published a 152 page book on 802.11ac, called "802.11ac: A Survival Guide." Published by O'Reilly: I purchased the ebook version (DRM free!) and found it to be quite informative. Recommended. -Charles Charles E. Spurgeon University of Texas at Austin / ITS Networking / 512.475.9265 -------------------- Here's an interesting bit on 802.11ac adoption in smartphones: -------------------- "Although 802.11ac is often dismissed as too power-hungry for mobile devices, singlestream 802.11 MIMO devices do not require significantly more power than their SISO predecessors. The main consumer of power in a MIMO device is the power-hungry digital signal processor that performs spatial mapping. By using only a single spatial stream, a portable device can reap significant benefits from 802.11ac's increased speed and wider channels without paying a significant power-consumption penalty. Although there will be an increase in power requirements to use wider channels, the trade-off is that transmissions go so much faster that the analog section is on for much less time. With a net battery life benefit, 802.11ac will be adopted widely in portable devices. In fact, 2013 saw the first introduction of an 802.11ac-capable smartphone." p 92, Chapter 5, "802.11ac Planning" ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at
