   RF ExposureInformation for WMP 100 WirelessMicroprocessor




   Maximum Antenna SystemGain

   Per FCC 47CFR$2.1091,mobile devicesarenot subjectto routine environmentalevaluation
   for RF exposureif they operatelessthan 1.5watts ERP in the 850 MHz bandand lessthan 3
   wattsERPin tbe PCSband.

   The maximum allowableantennasystemgain for the 850 MIIz bandis calculatedbelow
   basedonthe FCC47CFR$2.1091threshold(1.5 W ERP= 2.46W EIRP)for requiring
   routine environmentalevaluationfor RF exposurefor a mobile devicemeasuredat 20 cm
   from the antenna:

   GSM 850Band,PowerClass4 (2000mW),
   Duty FactorDF : 0.25.
   MeasruedPower: 33 dBm : 2000mW
   The maximum antennasystemgain is calculatedasfollows:
   g_num: EIRP [mW] / (P * DF) = 2460/ Q000 * 0.25) = 4.92.
   g_dBi : 10*LOG(g_num): 6.9.
   The maximum allowableantenna systemgain in the 850 MIIz bandis 6.9 dBi.

   The rnaximumallowableantennasystemgain for the GSM PCS band is limited per FCC
   47CFF'924.232O)2W EIRP peakpower limit. The maximum antennasystemgain is
   calculatedas follows:
   MeasuredPower:29,9 dBm : 980 rnW
   g_num: EIRP [mW] / P = 2000/ 980: 2.04.
   g_dBi = 10*LOG(g_num): 3.1.
   The maximum allowableantenna systemgain in the PCS bandis 3.1 dBi.
