When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine SAR test exclusion. 3.2.2 IC Test Procedure The SAR exclusion table from RSS-102 is reproduced below: Table 1: SAR evaluation – Exemption limits for routine evaluation based on frequency and separation distance Frequency (MHz) Exemption Limits (mW) At separation distance of ≤5 mm At separation distance of 10 mm At separation distance of 15 mm At separation distance of 20 mm At separation distance of 25 mm ≤300 71 mW 101 mW 132 mW 162 mW 193 mW 450 52 mW 70 mW 88 mW 106 mW 123 mW 835 17 mW 30 mW 42 mW 55 mW 67 mW 1 900 7 mW 10 mW 18 mW 34 mW 60 mW 2 450 4 mW 7 mW 15 mW 30 mW 52 mW 3 500 2 mW 6 mW 16 mW 32 mW 55 mW 5 800 1 mW 6 mW 15 mW 27 mW 41 mW Frequency (MHz) Exemption Limits (mW) At separation distance of 30 mm At separation distance of 35 mm At separation distance of 40 mm At separation distance of 45 mm At separation distance of 50 mm ≤300 223 mW 254 mW 284 mW 315 mW 345 mW 450 141 mW 159 mW 177 mW 195 mW 213 mW 835 80 mW 92 mW 105 mW 117 mW 130 mW 1 900 99 mW 153 mW 225 mW 316 mW 431 mW 2 450 83 mW 123 mW 173 mW 235 mW 309 mW 3 500 86 mW 124 mW 170 mW 225 mW 290 mW 5 800 56 mW 71 mW 85 mW 97 mW 106 mW Test Repot No.: NW2411-F006 211-71, Geumgok-ro, Hwaseong-si, Gyeonggi-do, Korea 18511 www.nct.re.kr TEL: +82-31-323-6070 FAX: +82-31-323-6071 Page 7 of 7 3.2.3 Test Result Test mode Max antenna gain Measured max RF output power Tune-up tolerance Max. power with tune-up tolerance (dBi) (dBm) (dB) (dBm) (mW) 2.4 GHz Transceiver 5.35 4.02 ± 0.50 4.52 2.83 High frequency Min. test separation distance Maximum estimated SAR(S) FCC limit IC limit Result (MHz) (mm) (mW) (mW) (mW) 2 480 5.00 0.89 3.00 3.94 PASS Note 1 : S = ((P(mW) / R))*√f(GHz) ** - S(mW): Maximum estimated SAR - P(mW): Max tuneup power - R(mm): Min. test separation distance - f(GHz): the RF channel transmit frequency
