American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 September 17, 2002 RE: Linksys Group, Inc. FCC ID: PKW-WUSB12 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please provide a photograph that shows the antenna. 2) This device may be directly plugged directly into any standard USB port. Other uses other than desktop computers (i.e. laptop use) becomes a portable RF Exposure condition. This condition exists because of the following: a) the antenna is integrated into the EUT b) If the device were to be directly plugged into the USB ports on a laptop, the antenna will be closer than the 20 cm distance if the user chooses to use the laptop in their lap. This same condition exists with PCMCIA Cards. However, this device appears to include a USB extension cable. This cable must be included with the product. Using this extension cable will ensure that the device will be used and installed in the proper manner. However, the users manual does not clearly instruct the user that this cable MUST be used. Sections of the manual that discuss the cable (section 3) and installation of the device (section 6) should clearly instruct the user that this cable must be used and how the device must be placed to meet the RF exposure requirements. Please provide an updated users manual. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

FCC ID: PKW-WUSB12 ADT No.910814R06 Operational Description The transmitter of the EUT is powered by host equipment from USB port. The antenna is Dipole Antenna with UFL connector. Under normal use condition, the user has to keep at least 20cm separation distance between radiator and the body of the user. The other instruction, please have a look at the users manual. DSSS Information This device is Direct Sequence Spread Spectrum, the data is mixed by pseudorandom code which is an orthogonal code. The mixed data is digital modulated by BPSK and QPSK technique depends on the data rates. The CCK coding is applied for increasing the data rate, and also the processing gain will be increased. The bit rates are 1,2,5.5,11Mbps, the symbol rates are 1,1,1.375,1.375Mbps, the chip rates are always 11Mbps. So, the Chip/symbol is 11,11,8 and 8 respectively. Although is higher bit rate, the processing gain is lower than 10, but the CCK coding used in higher bit rate will provide 2.2dB coding gain.

FCC ID: PKW-WUSB12 ADT No.: 910814R06 FCC TEST REPORT REPORT NO.: RF910814R06 MODEL NO.: WUSB12 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT:The Linksys Group, INC. ADDRESS:17401 Armstrong Ave. Irvine, CA 92614 ISSUED BY:Advance Data Technology Corporation LAB LOCATION:47 14th Lin, Chiapau Tsun, Linko, Taipei, Taiwan, R.O.C. 0528 ILAC MRA Lab Code: 200102-0 FCC ID: PKW-WUSB12 ADT No.: 910814R06 RF Exposure Measurement (Mobile Device) 1. Introduction 2.4GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. 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), and 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. 2. Classification The antenna of the product, under normal use condition, is at least 20cm away from the body of the user. Warning statement for keeping 20cm separation distance and the prohibition of operating next to a person has been printed on the user’s manual. So, this product is classified as the Mobile Device. 3. 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). FCC ID: PKW-WUSB12 ADT No.: 910814R06 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 30-30061.40.1631.06 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 30-30027.50.0730.230 300-1500......F/150030 1500-100,000......1.030 F = Frequency in MHz 4. 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 Pd is the limit of MPE, 1 mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 5. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. FCC ID: PKW-WUSB12 ADT No.: 910814R06 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 1dBi or 1.26 (numeric). 6.2 Output Power Into Antenna & RF Exposure Distance : CHANNEL CHANNEL FREQUENCY (MHz) OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( r ) FROM SKIN (Centi-Meter) 1241227.671.66 6243726.301.62 11246226.611.63 The minimum allowable distance is very close to the enclosure of the antenna and is very far away from the human being under normal use condition.
