Compliance Certification Services Inc. FCC ID: JNF-Z-217X Report No.: T110224206-RP2 APPENDIX I 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(i) and §1.1307(b)(1) of this chapter. EUT Specification EUT Handheld Computer WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz Frequency band (Operating) WLAN: 5.745GHz ~ 5.825GHz Bluetooth: 2.402GHz ~ 2.480 GHz Portable (<20cm separation) Device category Mobile (>20cm separation) 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 IEEE 802.11b: 17.12 dBm (51.52mW) Max. output power IEEE 802.11g: 21.55 dBm (142.88mW) Antenna gain (Max) 0.59 dBi (Numeric gain: 1.14) MPE Evaluation* Evaluation applied SAR Evaluation N/A Remark: The maximum output power is 21.55dBm (142.88mW) at 2442MHz (with 1.14 numeric antenna gain.) TEST RESULTS No non-compliance noted. Note: (1) This EUT none voice function (only data function). And According KDB447498 D01 4 C) iii). (2) This EUT is hand-held and hand-operated devices average maximum conducted output power is 14.41 dBm(IEEE 802.11g mode, IEEE 802.11b mode is 14.22dBm) is less than SAR test power theory (1000[f(GHz)]-0.5, 28.05 dBm), so SAR test for hand is not required. (3) And Body SAR average maximum conducted output power is less than SAR test power theory (300[f(GHz)]-0.5, 22.82 dBm), so SAR test for body is not required. Page 59 Rev. 00

Compliance Certification Services Inc. FCC ID: JNF-Z-217X Report No.: T110224206-RP2 Calculation 30 × P × G E2 Given E= & S= d 3770 Where E = Field strength in Volts / meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power density in milliwatts / square centimeter Combining equations and re-arranging the terms to express the distance as a function of the remaining variables yields: 30 × P × G S= 3770d 2 Changing to units of mW and cm, using: P (mW) = P (W) / 1000 and d (cm) = d(m) / 100 Yields 30 × (P / 1000) × G P×G S= = 0.0796 × 2 Equation 1 3770 × (d / 100) 2 d Where d = Distance in cm P = Power in mW G = Numeric antenna gain S = Power density in mW / cm2 Maximum Permissible Exposure Substituting the MPE safe distance using d = 20 cm into Equation 1: Yields S = 0.000199 × P × G Where P = Power in mW G = Numeric antenna gain S = Power density in mW / cm2 Page 60 Rev. 00

Compliance Certification Services Inc. FCC ID: JNF-Z-217X Report No.: T110224206-RP2 IEEE 802.11b mode: EUT output power = 51.52mW Numeric Antenna gain = 1.14 Æ Power density = 0.011688 mW / cm2 IEEE 802.11g mode: EUT output power = 142.88 mW Numeric Antenna gain = 1.14 Æ Power density = 0.032414 mW / 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.)
