RF Exposure Evaluation Applicant Name: Zebra Technologies Corp. FCC ID: XWX-TFF2005 IC: 8701A-TFF2005 Model : TFF-2005, WhereTag IV Module RFID, Real Time Locating System Equipment Class: DTS Portable application Exhibit documents: - FCC/IC test report GBCC04-U1 Rev A - Duty cycle measurements and calculations for WhereTag IV Module, TFF- 2005 Max. measured peak output powers in CW: - Pmax (802.11b beacon mode, 2412-2462 MHz) = 41.8 mW - Pmax (802.11g beacon mode, 2412-2462 MHz) = 39.8 mW - Pmax (DSSS mode, 2441.75 MHz) = 31.0 mW - Pmax (OOK mode, 2446.519 MHz) = 1.4 mW Max. measured average output power in CW: - Pmax average (802.11b client mode, 2412-2462 MHz) = 10 mW - Pmax average (802.11g client mode, 2412-2462 MHz) = 13 mW Duty Cycle Correction Factors: - 802.11b beacon mode = 3.6% - 802.11g beacon mode = 0.72% - DSSS mode = 2.55% - OOK mode = 13% The source-based time-averaged output power calculates to: - Psource (802.11b beacon mode) = 41.8 mW x 0.036 = 1.5 mW - Pspurce (802.11g beacon mode) = 39.8 mW x 0.0072 = 0.29 mW - Psource (DSSS mode) = 31.0 mW x 0.0255 = 0.79 mW - Psource (OOK mode) = 1.4 mW x 0.13 = 0.18 mW The low threshold value is determined by (60/f[GHz]) = 60/2.462 = 24.4 mW. Based on the evaluation using sourced-based time-averaged output power the product output power is below the threshold value and therefore no SAR evaluation is required.
