Compliance Certification Services Inc. Report No: C130314Z02-RP1_MPE FCC ID: PJZ242XA Date of Issue: April 28, 2013 RADIO FREQUENCY EXPOSURE LIMIT Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission's guidelines. See §15.247(b)(4) and §1.1307(b)(1) of this chapter. EUT Specification EUT Wireless-N Router WLAN: 2.412GHz ~ 2.462GHz Frequency band WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz (Operating) WLAN: 5.745GHz ~ 5825GHz Others Portable (<20cm separation) Device category Mobile (>20cm separation) Others __________________________ Occupational/Controlled exposure (S = 5mW/cm2) Exposure classification General Population/Uncontrolled exposure (S=1mW/cm2) Single antenna Multiple antennas Antenna diversity Tx diversity Rx diversity Tx/Rx diversity Max. output power 16.80dBm (47.86mW) Antenna gain (Max) 5.00dBi (Numeric gain:3.16) MPE Evaluation Evaluation applied SAR Evaluation Note: 1. The maximum output power is 16.80dBm (47.86mW) at 2462MHz (with 3.16 numeric antenna gain.) 2. For mobile or fixed location transmitters, no SAR consideration applied. The minimum separation generally be used is at least 20 cm, even if the calculations indicate that the MPE distance would be lesser. TEST RESULT No non-compliance noted. 1

Compliance Certification Services Inc. Report No: C130314Z02-RP1_MPE FCC ID: PJZ242XA Date of Issue: April 28, 2013 Calculation 30 × P × G E2 Given E= & S= d 3770 Combining equations and re-arranging the terms to express the distance as a function of the remaining variables yields: 30 × P × G S= Equation 1 3770d 2 Where d = distance in cm P = Power in mW G = Numeric antenna gain S = Power Density in mW / cm2 Maximum Permissible Exposure EUT Output Power=47.86mW Numeric antenna gain=3.16 Substituting the MPE safe distance using d=20 cm into Equation 1 : Yields The power density S = 30 × 47.86 × 3.16/ (3770 × 400) cm2 =3.009X 10-3mW/cm2 (For mobile or fixed location transmitters, the maximum power density is 1.0 mW / cm2 even if the calculation indicates that the power density would be larger.) 2
