RF Exposure / MPE Calculation No. : 12219846H-B Applicant : Sony Interactive Entertainment Inc. Type of Equipment : Wireless communication module Model No. : J20H096 *WLAN (2.4 GHz), Bluetooth Low Energy parts FCC ID : AK8M18DFT1 Sony Interactive Entertainment Inc. declares that Model: J20H096 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 “J20H096“ 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. [WLAN (2.4 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: PG S  Where 4  r2 P= 13.19 mW (Maximum average output power) Time average was used for the above value in consideration of 6-minutes time-averaging Burst power average was used for the above value in consideration of worst condition. G= 7.261 Numerical Antenna gain; equal to 8.61 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.01905 mW/cm UL Japan, Inc.

[Bluetooth Low Energy 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: PG S  Where 4  r2 P= 1.06 mW (Maximum average output power) Time average was used for the above value in consideration of 6-minutes time-averaging Burst power average was used for the above value in consideration of worst condition. G= 5.012 Numerical Antenna gain; equal to 7.0 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.00106 mW/cm Reference: [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: PG S  Where 4  r2 P= 1.40 mW (Maximum average output power) Time average was used for the above value in consideration of 6-minutes time-averaging Burst power average was used for the above value in consideration of worst condition. G= 5.012 Numerical Antenna gain; equal to 7.0 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.00140 mW/cm UL Japan, Inc. Ise EMC Lab. 4383-326 Asama-cho, Ise-shi, Mie-ken 516-0021 JAPAN Telephone : +81 596 24 8999 Facsimile : +81 596 24 8124

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: PG S  Where 4  r 2 P= 15.28 mW (Maximum average output power) Time average was used for the above value in consideration of 6-minutes time-averaging Burst power average was used for the above value in consideration of worst condition. G= 6.792 Numerical Antenna gain; equal to 8.32 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.02065 mW/cm Therefore, if WLAN 2.4GHz and Bluetooth Low Energy transmit simultaneously, S=0.01905 mW/cm2 + 0.00106 mW/cm2 =0.02011 mW/cm2 Therefore, if WLAN 2.4GHz and Bluetooth transmit simultaneously, S=0.01905 mW/cm2 + 0.00140 mW/cm2 =0.02045 mW/cm2 Therefore, if Bluetooth Low Energy and WLAN 5GHz transmit simultaneously, S=0.00106 mW/cm2 + 0.02065 mW/cm2 =0.02171 mW/cm2 Even taking into account the tolerance, this device can be satisfied with the limits.
