Basically, any manufacturer or company that would like to market a product that contains wireless capabilities over here in the US will need to send in the relevant files to the Federal Communications Commission (FCC), although some companies like Amazon prefer to go on the quiet by sneaking its products quietly to the FCC database through the names of shell companies, rather than their own, in order to minimize the amount of potential attention and hopefully, be able to spring a surprise to the market – and their competitors at the same time.
The 2ADU5-4902 label that you see above happens to be an “HDMI Digital Media Receiver” with support for 802.11ac WiFi and Bluetooth 4.1 connectivity, and it hails from Quill Royal LLC.

Ah well, we will just have to sit tight and wait for all to be clear.
