Well, its more like an order of magnitude slower than the Pi (and with a lot less RAM as well)

It's 2.4GHz, but only BLE and custom protocols (2 Mbit max, GFSK modulation).
The SoC can do RFID, but you have to connect a transmitter coil to use it, which doesn't seem to be the case from the photo.
I'd guess this was just used as a remote control backup connection if LAN is not working?
