Radiometrics Midwest Corporation (815) 293-0772 – [email protected] Operational Description FCC ID: CH8C90327WXX-06 The RF section of the EUT is a digitally modulated Spread Spectrum transceiver for use as a wireless LAN. VersaLink combines Westell's industry leading ADSL2+ modem technology with a high performance wireless and flexible router function. It provides wired networking using Ethernet and USB, and the convenience of 802.11b/g wireless. The optional uplink port transforms an Ethernet LAN port into an Ethernet WAN port for alternative access, including fiber, fixed wireless or connection to existing ADSL modems. The 2.4 GHz antenna has a reverse polarity SMA connector on it. The antenna used is a 2 dBi monopole. Wireless Card Description

RP-5394-RF Rev. 1 Page 1 of 1 RF exposure FCC ID: CH8C90327WXX-06 The 2.4 GHz transmitter Peak Power is 24.9 dBm output with 2 dBi antenna gain The following information provides the minimum separation distance for the EUT, as calculated from FCC OET 65 Appendix B, Table 1B “Guidelines for General Population/Uncontrolled Exposure” This calculation is based on the highest EIRP possible from the EUT considering maximum power and antenna gain. The following formulas were used: GP limit is = 1 mW/cm^2 above 1.5 GHz S= E^2/3770 mW/cm^2 E or V/m = (ERP*30)^0.5/d, (d in meters) d = ((ERP*30)/3770*S))^0.5 SPEAKAntennaMSD Freq.GP limitRF power GainERPEd MHzmW/cm^2 dBmdBiwattsV/mmeters 2473124.920.49061.40.062 GP is the limit for general Population/Uncontrolled Exposure MSD is the minimum Seperation Distance NOTE: For mobile or fixed location transmitters, minimum separation distance is 20 cm, even if calculations indicate MPE distance is less MPE for the transmitter is 20 cm.
