EDCS – 13349131 Attestation Statement of Compliance The Cisco ISR-AP1101AC-I-B Wi-Fi module has been evaluated for Maximum Permissible Exposure in compliance with 47 Code of Federal Regulations [Part 1.1307(b) (for fixed devices), Part 2.1091 (for mobile devices), and Part 2.1093 (for portable devices)]. Part 1.1307(b) refers to limits in Part 1.1310 and 2.1093. The evaluation was in accordance with methodology as referenced in KDB 447498 D01 General RF Exposure Guidance v06. This report serves as the additional technical analysis of the Cisco radio modules. This study addresses the following transmitters using the data derived in these test reports: 2.4GHz DTS report EDCS# 12316909 5GHz UNII-1 report EDCS# 12777514 5GHz UNII-2 report EDCS# 12857632 5GHz UNII-2ext reports EDCS# 12857638 5GHz UNII-3 report EDCS# 12857642 Cellular (info derived from the documents: AirPrime EM7455 Product Technical Specification & Customer Design Guidelines and Cisco LTE-ANTM-D antenna) Cellular (info derived from the documents: AirPrime_WP76xx_Product_Technical_Specification_ Rev6_2.pdf and Cisco LTE-ANTM-D antenna) The limits used for this evaluation are in line with the recommendations of the World Health Organizations (WHO) International Committee on Non Ionizing Radiation Protection (ICNIRP) as well as the American National Standards Institute (ANSI) C95.1. The limits chosen are of General Population/Uncontrolled Exposure. The following case scenarios were used: • Cellular pluggable 1 • Cellular pluggable 2 • 2.4GHz WLAN • 5GHz WLAN This device must be installed to provide a separation distance of at least 20 cm from all persons. Installers must be provided with antenna installation and transmitter operating conditions for satisfying RF exposure compliance. Based on the study this case scenario, the General Population/Uncontrolled Exposure and the minimum recommended distance is around 20cm (8 inches) from the antenna.

EDCS – 13349131 4.0 Calculations Given E=√(30*P*G)/d and S=E^2/3770 where E=Field Strength in Volts/meter P=Power in Watts G=Numeric Antenna Gain d=Distance in meters S=Power Density in mW/cm^2 Combine equations and rearrange the terms to express the distance as a function of the remaining variables: d=√((30*P*G)/(3770*S)) Changing to units of power in mW and distance in cm, using: P(mW)=P(W)/1000 d(cm)=100*d(m) yields d=100*√((30*(P/1000)*G)/(3770*S)) d=0.282*√(P*G/S) where d=Distance in cm P=Power in mW G=Numeric Antenna Gain S=Power Density in mW/cm^2 Substituting the logarithmic form of power and gain using: P(mW)=10^(P(dBm)/10) G(numeric)=10^(G(dBi)/10) yields d=0.282*10^((P+G)/20)/√S Equation (1) and s=((0.282*10^((P+G)/20))/d)^2 Equation (2) where d=MPE distance in cm P=Power in dBm G=Antenna Gain in dBi S=Power Density in mW/cm^2

EDCS – 13349131 5.0 Results Equation (1) and the measured peak power are used to calculate the MPE distance. Note that for mobile or fixed location transmitters such as an access point, the minimum separation distance is 20 cm even if the calculations indicate that the MPE distance may be less. S=1mW/cm^2 maximum. Using the peak power levels recorded in the test report along with Equation 1 above, the MPE distances are calculated as follows.
