RF EXPOSURE COMPLIANCE REQUIREMENT
1.1.Rules Part No.
15.247(b)

1.2.Limit
The conducted output power limit specified in paragraph (b) of this
section is based on the use of antennas with directional gains that do
not exceed 6 dBi. Except as shown in paragraph (c) of this section, if
transmitting antennas of directional gain greater than 6 dBi are used,
the conducted output power from the intentional radiator shall be
reduced below the stated values in paragraphs (b)(1). (b)(2). and (b)(3)
of this section, as appropriate, by the amount in dB that the directional
gain of the antenna exceeds 6 dBi.

1.3.Test Procedure
EUT RF Exposure
The Max Conducted Peak Output Power is 13.42dBm(21.97mW) in
lowest channel (2.441GHz);
The best case gain of the antenna is -2dBi.
According to the formula. calculate the EIRP test result:
EIRP= P x G = 21.97mW x 1 = 21.97mW ①
SAR requirement:
② S= 60 / f(GHz) = 60/2.441 = 24.58mW ②;
① < ②.
So the SAR report is not required.
