These limits are designed to provide reasonable protection against harmful interferencein a residential installation. This equipment generates, uses, and can radiate radio fre-quency energy and, if not installed and used according to the instructions, may causeharmful interference to radio communications. However, there is no guarantee that inter-ference will not occur in a particular installation. If this equipment does cause harmfulinterference to radio or television reception, which is found by turning the equipment offand on, the user is encouraged to try to correct the interference by one or more of thefollowing measures:• Reorient or relocate the receiving antenna • Increase the separation between the equipment or devices • Connect the equipment to an outlet other than the receiver's • Consult a dealer or an experienced radio/TV technician for assistance FCC Caution: Any change or modification to the product not expressly approved byLinksys could void the user's authority to operate the device.FCC RF Radiation Exposur e Statement To comply with the FCC and ANSI C95.1 RF exposure limits, the antenna(s) for thisdevice must comply with the following: • Access points with 2.4 GHz integrated antenna must operate with a sepa- ration distance of at least 20 cm fr om all persons using the cable pr ovided and must not be co-located or operating in conjunction with any other antenna or transmitter.

FCC ID: Q87-WUSB54GS Report No.: RF930519L09 Operational Description This device is a Wireless-G USB Network Adapter with SpeedBooster, 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 host equipment via a USB interface. The antenna is Dipole antenna without a connector. The other instruction, please have a look at the users manual.

FCC ID: Q87-WUSB54GS Report No: SA930519L09 1 RF EXPOSURE REPORT REPORT NO.: SA930519L09 MODEL NO.: WUSB54GS ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Cisco-Linksys, LLC ADDRESS: 121 Theory Drive, Irvine, CA 92612 (USA) ISSUED BY: Advance Data Technology Corporation LAB LOCATION: No. 19, Hwa Ya 2nd rd., Kueishan, Taoyuan, Taiwan, R.O.C. FCC ID: Q87-WUSB54GS Report No: SA930519L09 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: Q87-WUSB54GS Report No: SA930519L09 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 20cm.

(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 20cm far away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device.
