Dear Steve I correct the FRN no on 731 form. And reply your comments as below: Question #1: User manual p43; Power show on the page are 20dBm, but report measured 17dBm (50.12mw) max. Please clarify and make necessary correction. Answer: This is a typo and we have modified the power in p43 and, also, the FCC and Canada statement in the last page of the user's manual. Question #2: Test report P7; Per FCC section 15.203, all intentional radiator shall use unique coupling device on antenna jack or connector. However, this device seems incorporated a non-unique standard N-type connector on the antenna port. Please confirm and make necessary change. Answer: This is for professional installation only product. Please refer of revised "Professional Installation Attestation" and the new section of professional installation instruction in the revised user's manual. Question #3: FRN not matching the Form 731 info. Corrected. Please check the revised manual for FCC project and Canada project. Thanks for your assistance!

FCC ID: O9C-WL565 Report No.: RF930920L09 Operational Description This device is a Indoor 11g 54Mbps Building to Building Bridge, Outdoor 11g 54Mbps Building to Building Bridge which operates in the 2.4GHz frequency spectrum with throughput of up to 54Mbps which OFDM technique will be applied. If the signal to noise radio is too poor which could not support 54Mbps, the 11Mbps data rate with CCK technique will be applied. The transmitter of the EUT is powered by Power over Ethernet. The antennas are Dipole and Patch antenna with N -Type connector. The other instruction, please have a look at the users manual.

FCC ID: O9C-WL565 Report No: SA930920L09 1 RF EXPOSURE REPORT REPORT NO.: SA930920L09 MODEL NO.: WL-565, WL-565B ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: 3Com Corporation ADDRESS: 350 Campus Drive, Marlborough, MA 01752- 3064, U.S.A. ISSUED BY: Advance Data Technology Corporation TEST LOCATION: No. 19, Hwa Ya 2 nd Rd., Wen Hwa Tsuen, Kwei Shan Hsiang, Taoyuan Hsien 333, Taiwan, R.O.C. FCC ID: O9C-WL565 Report No: SA930920L09 2 RF Exposure Measurement (Mobile Device) 1. Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 300-1500......F/15006 1500-100,000......1.030 F = Frequency in MHz FCC ID: O9C-WL565 Report No: SA930920L09 3 3. Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance 200cm. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4 EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. Classification This device is not fixed inside the host equipment, it is connected with host through wire. So it is easy to be re-located in the place where at least 200cm far away from the body of the user. Warning statement to the user for keeping at least 200cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device. FCC ID: O9C-WL565 Report No: SA930920L09 4 6 Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 18.0dBi or 63.095 (numeric). 6.2 Output Power Into Antenna & RF Exposure Distance: For 802.11b: Channel Channel Frequency (MHz) Output Power to Antenna (mW) Power Density (mW/cm 2 ) Limit of Power Density (mW/cm 2 ) 1 2412 12.62 0.0016 1.0 6 2437 50.12 0.0063 1.0 11 2462 12.65 0.0016 1.0 For 802.11g: Channel Channel Frequency (MHz) Output Power to Antenna (mW) Power Density (mW/cm 2 ) Limit of Power Density (mW/cm 2 ) 1 2412 7.94 0.001 1.0 6 2437 50.12 0.006 1.0 11 2462 7.98 0.001 1.0
