Analysis Report
The Equipment Under Test (EUT) is a 2.4GHz transceiver (i.e. Controller) for a
RC Plane. The EUT is powered by DC12.0V (8X1.5V AA batteries). The operating
frequency is 2408MHz, 2424MHz, 2442MHz and 2460MHz. After pairing with
plane, the plane can be controlled to fly forward, upward/downward, turn left/right
directions and any motions. Also, the EUT has a charging circuitry, the
corresponding plane can be charged by the EUT.

Antenna Type: Internal antenna
Antenna Gain: 0dBi
Nominal rated field strength: 95.0 dBμV/m at 3m
Maximum allowed field strength of production tolerance: +/- 3dB

According to the KDB 447498:

Based on the Maximum allowed field strength of production tolerance was 98.0dBμV/m
at 3m in frequency 2.4GHz, thus;

The EIRP = [(FS*D) ^2*1000 / 30] = 1.893mW

Conducted power = Radiated Power (EIRP) – Antenna Gain
So;

Conducted Power =1.893mW.

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.460) mW
= 9.56 mW

Since the above conducted output power is well below the SAR Exclusion threshold
level, so the EUT is considered to comply with SAR requirement without testing.
