-RAlink SoC found inside an AT&T femtocell. Contains a MIPS CPU running Linux and some kind of radio. Not sure what... both the GSM and GPS are on separate parts of the board. Maybe 802.11?
+RAlink SoC found inside an AT&T femtocell.
+Googling the part number on the die (RT3052) shows http://www.mediatek.com/_en/01_products/04_pro.php?sn=1045. The part is most likely a relabeled/fused RT3052:
+  * 2.4 GHz 802.11n radio (2x MIMO)
+  * 384 MHz MIPS 24KEc CPU, 32KB I-side and 16KB D-side cache
+  * 5-port 10/100 switch including PHYs
+  * USB OTG
+  * Gigabit Ethernet MAC (RGMII to off-die PHY)
