Sony Interactive Entertainment Inc. declares that Model: J20H091 complies with FCC radiation
exposure requirement specified in the FCC Rule 2.1091 (for mobile).
RF Exposure Calculations:
The following information provides the minimum separation distance for the highest gain antenna
provided with the “J20H091“ as calculated from (B) Limits for General Population / Uncontrolled
Exposure of TABLE 1- LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) of
§1.1310 Radiofrequency radiation exposure limits.
[Bluetooth part]
This calculation is based on the highest EIRP possible from the system,
considering maximum power and antenna gain, and considering a 1mW/cm^2 uncontrolled
exposure limit. The Friis formula used was:
S 
PG
4  r2
Where
P=
1.33 mW (Maximum average output power)
Frame power was used for the above value in consideration of 6-minutes time-averaging
Burst power was used for the above value in consideration of worst condition.
G=
4.365 Numerical Antenna gain; equal to 6.4 dBi
r=
20 cm (Separation distance)
Power Density Result S =
0.00115 mW/cm

[WLAN (2.4 GHz) part]
The following information provides the minimum separation distance for the highest gain antenna
provided with the “J20H091“ as calculated from (B) Limits for General Population / Uncontrolled
Exposure of TABLE 1- LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) of
§1.1310 Radiofrequency radiation exposure limits.
This calculation is based on the highest EIRP possible from the system,
considering maximum power and antenna gain, and considering a 1mW/cm^2 uncontrolled
exposure limit. The Friis formula used was:
S 
PG
4 r
Where
P=
19.35 mW (Maximum average output power)
Frame power was used for the above value in consideration of 6-minutes time-averaging
Burst power was used for the above value in consideration of worst condition.
G=
7.261 Numerical Antenna gain; equal to 8.61dBi
r=
20 cm (Separation distance)
Power Density Result S =
0.02795 mW/cm
Reference:
[WLAN (5 GHz) part]
This calculation is based on the highest EIRP possible from the system,
considering maximum power and antenna gain, and considering a 1mW/cm^2 uncontrolled
exposure limit. The Friis formula used was:
S 
PG
4  r2
Where
P=
15.42 mW (Maximum average output power)
Frame power was used for the above value in consideration of 6-minutes time-averaging
Burst power was used for the above value in consideration of worst condition.
G=
5.358 Numerical Antenna gain; equal to 7.29dBi
r=
20 cm (Separation distance)
Power Density Result S =
0.01644 mW/cm
Therefore, if Bluetooth and WLAN 2.4GHz transmit simultaneously,
S=0.00115 mW/cm2+0.02795 mW/cm2
=0.0291 mW/cm2
Therefore, if Bluetooth and WLAN 5GHz transmit simultaneously,
S=0.00115 mW/cm2 + 0.01644 mW/cm2
=0.01759 mW/cm2
Even taking into account the tolerance, this device can be satisfied with the limits.
