RF Exposure / MPE Calculation No. : 12786766H Applicant : Panasonic Corporation Type of Equipment : WiFi Module Model No. : WL17A FCC ID : ACJ9TGWL17A Panasonic Corporation declares that Model: WL17A 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 “WL17A“ 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. [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= 44.67 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= 1.291 Numerical Antenna gain; equal to 1.11dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.01147 mW/cm [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  r2 P= 39.81 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= 1.862 Numerical Antenna gain; equal to 2.7dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.01475 mW/cm

FZ-55 contains certified wireless module (FCC ID: ACJ9TGWL18A). The WiFi module and the Wireless module both transmit simultaneously. Compliance for simultaneous transmission are shown by the following calculations. Reference: [WL18A module WLAN (SISO) part highest value] 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= 100.00 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= 1.660 Numerical Antenna gain; equal to 2.2 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.03302 mW/cm [WL18A module WLAN (MIMO) part highest value] 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= 125.89 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= 1.660 Numerical Antenna gain; equal to 2.2 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.04157 mW/cm

Reference: [WL18A module Bluetooth part highest value] 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= 8.91 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= 1.524 Numerical Antenna gain; equal to 1.83 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.00270 mW/cm Therefore, if WLAN (WL17A), WLAN and Bluetooth (WL18A) transmit simultaneously, the combination to be the maximum is as follows; < WLAN (WL17A) + WLAN(SISO) + Bluetooth (WL18A) > S = 0.01475 mW/cm2 + 0.03302 mW/cm2 + 0.00270 mW/cm2 = 0.05047 mW/cm2 < WLAN (WL17A) + WLAN(MIMO) > S = 0.01475 mW/cm2 + 0.04157 mW/cm2 = 0.05632 mW/cm2 Even taking into account the tolerance, this device can be satisfied with the limits.
