Despite having hardware capable of implementing three radios, this device
 * appears to only use the 2.4GHz radio of the IPQ4019 configured as 2x2.

User Manual says, "wireless-AC speeds up to 1400Mbps on the 5GHz band
 * & 300Mbps on the 2.4GHz band concurrently". This is likely inaccurate.

RF Exposure document shows that :
 * two antennas are used for the 2.4GHz radio (ANT 0+1) and
 * four antennas are used for the 5GHz radio (ANT 0+1+2+3).
