American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 November 26, 2002 RE: FCC ID: PKW-NWU11B Attention: Vivi Wang I have a few comments on this Application. 1 Please note that only in certain circumstances can the two condition statement not be on the device. 15.19(s)(5) states, “ When the device is so small or for such use that it is not practicable to place the statement specified under paragraph (a) of this section on it, the information required by this paragraph shall be placed in a prominent location in the instruction manual or pamphlet supplied to the user or, alternatively, shall be placed on the container in which the device is marketed. However, the FCC identifier or the unique identifier, as appropriate, must be displayed on the device.” Please note, your device and label size appear to be more than adequate to have the two condition statement placed on it. Please provide a corrected label or separate label to be placed on the device with the required two condition statement per 15.19. Alternately, please provide adequate justification as to why this statement cannot be on the device. Again, pleas remember that size is the only limiting factor and the device appears to be sufficiently large for this statement, xxx 2 Your MPE calculations say that the antenna gain is 0dBi. Yet you also state that the antenna is a dipole. Dipole antennae have a 2.14dBi gain. Please correct the MPE to reflect to true nature of a dipole antenna, alternately please correct the documentation stating the actual type antenna used. xxx 3 Your block diagram has Asia fonts that are not readable by the FCC adobe reader. Please remove Asian fonts fr om the Block diagram. xxx 4 Your report states that the device was received October 30, 2002 but tested May 2002. Please correct the report to reflect correct receive and test dates. xxx 5 Your line conducted test data is in accordance with the old standards. The new limits go from 150kHz to 30 MHz. While it is still OK to test to the older limits, you must verify that you are aware of the transition rules of 15.37. Please confirm that you are aware of these rules. xxx Dennis Ward 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.

FCC ID: PKW-NWU11B ADT No.911030R04 Operational Description The transmitter of the EUT is powered by host equipment from USB port. The antenna is Dipole antenna, and there is no antenna 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-NWU11B ADT No.: 911030R04 FCC TEST REPORT REPORT NO.: RF910208R02E MODEL NO.: NWU11B 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-NWU11B ADT No.: 911030R04 RF Exposure Measurement (Mobile Device) 1. Introduction 2.4 GHz 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 20 cm away from the body of the user. Warning statement for keeping 20 cm separation distance and the prohibition of operating next to a person has been printed on the users 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-NWU11B ADT No.: 911030R04 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-NWU11B ADT No.: 911030R04 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 2.14 dBi or 1.64(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) 1241238.552.24 6243738.192.23 11246232.362.05 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.
