Overview

Wi-Fi Certified : WFA55415 (as of 06/30/2014)

  • The manufacturer stated in FCC test report is Compal (Compal Networking
[KunShan]), a part of Arcadyan - same manuf. noted for ASUS RT-AC56U
(WG9117GAC). See also ASUS EA-AC87 (Arcadyan WA5005AAC44-ASU)..
  • The primary SoC for device is Broadcom BCM4709 (ARM Cortex-A9 DualCore @1 GHz).
The 2.4GHz radio is implemented with BCM4360, connected via PCIe to BCM4709.
The 5GHz radio is contained w/ independent Quantenna chipset (QT3840BC+QT2518B),
(QSR1000, ARC 700 core), which is connected in some fashion (RGMII) to BCM4709.

"RT-AC87U REV 1.50" board shown, an Arcadyan typical label is found on board noted
as being BCM4709 (BCM4709A0) based. ARC 700 family core used w/ Quantenna SoC,
which seems to have also been used with at least some older Quantenna SoC's.
SoC's/radios are segmented - 2.4 GHz is handled on BCM4360 directly connected
to the BCM4709, while 5 GHz is handled on the independent Quantenna SoC.
The Quantenna firmware is contained within the main Flash and uploaded at boot.
