Catapult TECH 815-00027

"48RAAM01.SGC" and "2019.03.14" are silkscreened on the board in the FCC photos.

FCC internal photos show only one radio chip in this device, the Marvell 88W8997P-NXW2. FCC test report documents claim that it supports concurrent 2.4GHz and 5GHz WLAN operation. The product page for the 88W8997 chip says that it provides, "concurrent applications support for a device to have two independent radio links, without compromising the 2x2 MIMO link" which seems to suggest that the single chip could be providing the two concurrent 2x2:2 radio links at 5GHz and 2.4GHz.

Additional models are covered by this FCC entry. The Catapult TECH 815-00029 is also called the Madesafe Gateway and has an external bluetooth antenna instead of internal. The Catapult TECH 815-00028 is referred to as the Madesafe/IOT Gateway and it contains an internal module (FCC ID: W7Z-WD907102) which provides Zigbee functionality.
