Compliance Certification Services Inc. Report No: 50317001-RP1 FCC ID: H8NWLL4071 Date of Issue: June 09, 2005 7.6 RADIO FREQUENCY EXPOSURE LIMIT U-NII devices are subject to the radio frequency radiation exposure requirements specified in §1.1307(b), §2.1091 and §2.1093 of this chapter, as appropriate. All equipment shall be considered to operate in a "general population/uncontrolled" environment. Applications for equipment authorization of devices operating under this section must contain a statement confirming compliance with these requirements for both fundamental emissions and unwanted emissions. Technical information showing the basis for this statement must be submitted to the Commission upon request. EUT Specification EUT 802.11a/b/g Mini PCI Card Frequency band (Operating) WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.15GHz ~ 5.35GHz WLAN: 5.725GHz ~ 5.850GHz Bluetooth: 2.402 GHz ~ 2.482 GHz Others: Device category Portable (<20cm separation) Mobile (>20cm separation) Others __________________________ Exposure classification General Population/Uncontrolled exposure (S=1mW/cm2) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Max. output power Base mode: 17.90 dBm (61.66mW) Turbo mode: 13.85 dBm (24.27mW) Antenna gain (Max) 1.2 dBi (Numeric gain: 1.32) Evaluation applied MPE Evaluation SAR Evaluation* N/A Remark: 1. The maximum output power is 17.90dBm (61.66mW) at 5320MHz (with 1.32 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 RESULTS No non-compliance noted. Page 41 Rev. 00
