Transmit Power
The Bluetooth component shall operate as a Class 1.5 Bluetooth device
with a maximum transmit power of + 14 dBm and 10 dBm for BR and EDR,
respectively.
1. Wi-Fi 6E requires a Wi-Fi 6E router, sold separately, to function in the 6GHz band. Availability of public wireless access points
limited. Wi-Fi 6E is backwards compatible with prior 802.11 specs. And available in countries where Wi-Fi 6E is supported. Wi-Fi 6E
is designed to support gigabit data rate when transferring files between two devices connected to the same router. Requires a
wireless router, sold separately, that supports 80MHz and higher channels.
2. The FCC has declared as of September 1, 2014 products that utilize passive scanning on channel 12/13 and are capable of
transmitting must fully comply with requirements of 15.247 or otherwise disable those channels.
3. Check latest software/driver release for updates on supported security features.
4. Receiver sensitivity is measured at a packet error rate of 8% for 802.11b (CKK modulation) and a packet error rate of 10% for
802.11a/g (OFDM modulation).
