| + | [* black] There are three antennas in the Sonos Play:3 attached to a communications card on the motherboard, and then kept 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. |
