Compliance Certification Services Inc. Report No.: T100120212-RP1 FCC ID: P27-RC8120 Date of Issue: June 11, 2010 APPENDIX I RADIO FREQUENCY EXPOSURE LIMIT According to §15.247(i), 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 § 1.1307(b)(1) of this chapter. EUT Specification EUT Compact Wireless Network Camera WLAN: 2.412GHz ~ 2.462GHz Frequency band WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz (Operating) WLAN: 5.745GHz ~ 5.825GHz 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 IEEE 802.11b mode: 23.44 dBm (220.80 mW) IEEE 802.11g mode: 25.23dBm (333.43 mW) Max. output power draft 802.11n Standard-20 MHz Channel mode: 27.89 dBm (615.17 mW) draft 802.11n Wide-40 MHz Channel mode: 27.57 dBm (571.47 mW) Dipole Antenna / Gain: 1.8 dBi (Numeric gain: 1.51) Antenna gain (Max) PIFA Antenna / Gain: 2.68 dBi (Numeric gain: 1.85) MPE Evaluation* Evaluation applied SAR Evaluation N/A Remark: 1. The maximum output power is 27.89dBm (615.17mW) at 2437MHz (with 1.85 numeric antenna gain.) 2. DTS device is not subject to routine RF evaluation; MPE estimate is used to justify the compliance. 3. For mobile or fixed location transmitters, no SAR consideration applied. The maximum power density is 1.0 mW/cm2 even if the calculation indicates that the power density would be larger. TEST RESULTS No non-compliance noted. Page 93 Rev. 00
