-	[* black] ~~There are~~ three antennas in the Sonos Play:3 attached to a communications card on the motherboard and held in place with a soft glue.
-	[* black] ~~We speculate that two~~ of ~~these~~ antennas ~~(the green ones) are responsible for aiding in the transmission of SonosNet~~, the ~~secure~~, ~~AES-encrypted, peer-to-peer~~ wireless mesh network ~~created~~ to ~~connect~~ Sonos ~~devices~~.
-	[* black] The length of the antenna traces are listed on the antenna board. The antenna design seems to be that of an [link\|http://www.antenna-theory.com/antennas/aperture/ifa.php\|Inverted F-Antenna]~~. IFAs are~~ common in small electronics and ~~are~~ implemented ~~as a method~~ to reduce antenna size and improve multiple input multiple output ([link\|http://en.wikipedia.org/wiki/MIMO#Functions_of_MIMO\|MIMO]) systems.
