Subject: [WIRELESS-LAN] New 802.11ac book from Matthew Gast
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.

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.
