The white points indicate that the scanned area must be greater than the projected area of the station under test on the mannequin. 5.2.9.4.3 The distance between the points measured during the scanning and the mannequin surface must be of 8 mm or lower and remains constant, with a variation of ±1 mm. Laterally, the measured points must have enough spatial resolution to the interpolation algorithm of the SAR measurement systems to identify the local with SAR peaks inside of the half of linear dimension 3 of a volume side of the zoom scan, so, the step of the spatial mesh of the measured points must be lower than 20 mm. 5.2.9.4.4 Is recommended that, on all the scanning measurement points, the probe angle in relation to the normal line to the surface is lower than 30. 5.2.9.4.5 On the SAR distribution obtained on the scanning, must be identified the position with the maximum value of SAR, as well as any local maximum with SAR value inside of 2 db that is not inside of the volume of the zoom scan. Additional peaks must be measured only when the primary peak is within 2 db of the SAR limit SAR (ie, 1.26 W/kg for a limit of 2 W/kg on a cube of 10 g). 5.2.9.4.6 The position(s) identified on the item 5.2.9.4.5 (previous) will be evaluated with the volume zoom scan to determine the higher average SAR value on the cube of 10 g. 5.2.9.4.7 If a peak is founded on a distance from the scanning edge lower than the half of the cube linear dimension (10.8 mm for cube of 10 g and 5.0 mm for the cube of 1 g), the scanning area must be increased, if possible. 5.2.9.5 Step 3 Zoom Scan 5.2.9.5.1 After the peaks are located on the area scan (item 5.2.9.4), the maximum spatial average SAR must be obtained though the zoom scan. This scanning has a minimum dimension of 1,5 times the edge length of a cube of 1 gram or 10 grams, or 15 and 32 mm, respectively. 3 The half of the linear dimension of a cube of 10 grams is 10.8 mm and of the cube of 1 gram is 5 mm.

5.2.9.5.2 The zoom scan must be at least of 32 mm x 32 mm x 30 mm with 5 x 5 x 7 points centered at the peak SAR local determined on the area scan. 5.2.9.5.3 The mesh step on the vertical direction on the zoom scan must be calculated by the relation (8-f [GHz]) and not be greater than 5 mm. On the horizontal direction, parallel to the surface, the step must be calculated by the relation (24/f [GHz]) and not be greater than 8 mm, since is adopted the regular spacing on the mesh (see Annex C.3.3 of the Standard 62209 1 [Item 2 - VI], if the mesh spacing is not regular, the step on the horizontal direction must be calculated by the relation (12/f [GHz]) and not be greater than 4 mm. The use of these resolutions allows that the interpolation algorithm calculates the SAR values on a mesh with step of 2 mm with error lower than 5%. If other resolutions are adopted is necessary to validate this result. 5.2.9.5.4 If the volume of the chosen cube to calculate the maximum spatial average SAR touched any perimeter of the zoom scan volume, the zoom scan must be repeated with the zoom scan center changed to the new maximum SAR location. 5.2.9.5.5 For all other secondary peaks found on the step 2 (item 5.2.9.4) that are inside of 2 db of the maximum peak and are not inside of this zoom scan, the step 3 must be repeated. 5.2.9.5.6 Is recommended that, on all the measurement points on the zoom scan, the probe angle in relation to the normal line to the surface is lower than 30. 5.2.9.5.7 The value of the maximum spatial average SAR must be obtained through interpolation and extrapolation procedures. These procedures must follow the established on the Annex C of the Standard 62209 1 [Item 2 VI] or in the items 6.5.3, F.4.1.3, F.4.1.4 and F.4.1.5 of the Standard 1528 2003 [Item 2 IV]. 5.2.9.5.8 The values of SAR interpolated and extrapolated of the zoom scan measurements must be integrated on the form of a cube of 10 grams to determine the maximum spatial average SAR on the zoom scan region. The SAR conformity of the portable terminal station under test is determined through the greater value of SAR 10 grams obtained on all the zoom scans realized on each area scan. 5.2.9.6 Step 4 Power reference measurement (variation drift ) 5.2.9.6.1 The local SAR 4 must be measured exactly on the same place of the Step 1 (item 5.2.9.3). The absolute value of the measurement variation between the obtained on the Step 4 and on the Step 1 must be lower than ± 5%. 5.2.9.6.2 If several zoom scans are realized, the power reference measurement must be always measured. The variation must be always calculated for each one of the measurements, but the variation between the obtained on the Step 1 and the last measurement must be lower than ± 5%. 4 If the measurement system provides the variation result ( drift ) on electric field values (V/m), the maximum absolute variation must be of ± 0.2 db.

5.2.10 Evaluation of the maximum spatial average SAR for all configurations of a portable terminal stations operating closer to the head 5.2.10.1 The determination of the greater value of the maximum spatial average SAR of a portable terminal station must be measured on all positions of the station, all configurations and all the operation modes on each frequency band according established on steps 1 to 3 as follows. The Figure 13 shows the block diagram of the process to determine the maximum spatial average SAR. 5.2.10.1.1 Step 1 The tests described on the item 5.2.9 must be realized on the channel that is closer to the transmission frequency band center for: a) All the positions of the portable terminal station under test, cheek and tilt, for both sides, left and right, of the mannequin SAM, as described on the item 5.2.3. b) All configurations for each position of the previous item (a), ie, extended and retracted antenna, as described on 5.2.2. c) All operational models for each position of item (a) and configurations of item (b) on each frequency band, ie analogical and digital, as described on 5.2.2. If the number of channels to be tested, as calculated on item 5.2.2 (Nc > 3), is greater than three, so all channels, configurations and modes must be tested for each one of the previous configurations. 5.2.10.1.2 Step 2 For the condition that provides the maximum spatial average SAR determined on Step 1 (item 5.2.10.1.1) for each frequency, all the tests described on item 5.2.9 must be realized on all the other channels of the band, on the lower and upper channels. Additionally, for all the other conditions (station positions, configurations and operational modes) where the value of the maximum spatial average SAR determined on Step 1 (item 5.2.10.1.1) within 3 db of applicable SAR limit. It is recommended that all other conditions are tested. 5.2.10.1.3 Step 3 The values obtained on Steps 1 and 2 must be examined to determine the maximum spatial average SAR of the portable terminal station under test.

5.2.11 Evaluation of the maximum spatial average SAR for all configurations of a portable terminal stations operating closer to the body The determination of the greater value of the maximum spatial average SAR of a portable terminal station must be measured on all positions of the station, all configurations and all the operation modes on each frequency band according established on steps 1 to 3 as follows. The Figure 14 shows the block diagram of the process to determine the maximum spatial average SAR. 5.2.11.1.1 Step 1 The tests described on item 5.2.4 must be analyzed and chosen the use situations that the portable terminal station will have, such as which accessories are available for sue together with this station. After this choice the tests must be realized on the channel closer to the center of the transmission frequency band for: a) All the positions of the portable terminal station under test of the mannequin plan. b) All configurations for each position of the previous item (a), ie, extended and retracted antenna, as described on 5.2.2. c) All operational models for each position of item (a) and configurations of item (b) on each frequency band, ie analogical and digital, as described on 5.2.2. If the number of channels to be tested, as calculated on item 5.2.2 (Nc > 3), is greater than three, so all channels, configurations and modes must be tested for each one of the previous configurations. 5.2.11.1.2 Step 2 For the condition that provides the maximum spatial average SAR determined on Step 1 (item 5.2.11.1.1) that are within 3 db of the applicable SAR limit must be realized all the tests described on 5.2.9 on all the other channels of the band, ie, on the lower and upper channels. It is recommended that all other conditions are tested. 5.2.11.1.3 Step 3 The values obtained on Steps 1 and 2 must be examined to determine the maximum spatial average SAR of the portable terminal station under test for each one of the positions and accessories analyzed.

5.3 Measurement Uncertainty 5.3.1 The concepts of uncertainty estimative of the SAR values produced by the portable terminal stations are based on the general rules provided by ABNT/ISO/IEC on the Guide for expression of the measurement uncertainty [Item 2 XIII]. 5.3.2 The total uncertainty expanded to a confidence level of 95% for the measurement of the maximum spatial average SAR cannot be greater than ± 30% for values on the band between 0.4 W/kg up to 10 W/kg. 5.3.3 The calculation of the uncertainty must be realized according to the item 7.2 and the Annex E of the Standard 1528 2003 [Item 2 IV] or with the item 7 of the Standard 62209 1 [Item 2 VI] for SAR measurements on portable terminal stations that operates closer to the user s head (Mannequin SAM) and according to the item 7 of the Standard 62209 2 [Item 2 - VII] for SAR measurements on portable terminal stations that operates on other positions that not those located against the head s side (Mannequin plan). 5.3.4 The uncertainty values, calculated according previous paragraph, must be informed at the test report of the terminal station under test. 5.4 Measurement Report 5.4.1 The results obtained from the measurements must be passed to a measurement report that must include all the information necessary to the interpretation of the obtained results. The guidelines for the measurements report preparation are found on the item 5.10 of the Standard 17.025 of ABNT/ISO/IEC [Item 2 XII]. 6. Procedure for test of portable terminal station with multiband operation 6.1 This procedure must be applied to portable terminal stations with multiband operation that have two or more transmitters on the frequencies f1, f2,...fx separated for more than one bandwidth of the isotropic probe calibration used on the SAR measurement system or by the bandwidth of the tissue simulator liquid, what is less, ie, when SAR cannot be mapped simultaneously using the same probe and the same liquid. 6.2 It can be used the following methods to obtain the maximum multiband SAR value that must meet the established on the legislation. 6.3 Method 1 Mapping by the sum of the maximum spatial average SAR values 6.3.1 This method provides the easiest and most conservative estimative for obtaining the maximum spatial average SAR of the portable terminal stations with multiband operation. 6.3.2 Step 1: To obtain the maximum spatial average SAR value separately on all frequencies (frequency 1, frequency 2,... frequency x) of the station with multiband operation, according to established on item 5.

6.3.3 Step 2: To sum the maximum spatial average SAR values to obtain the multiband SAR value. 6.4 Method 2 Mapping by the selection of the highest mapped values of the maximum spatial average SAR 6.4.1 This method gives an accurate estimate of the multiband SAR when the zoom scan distributions obtained separately have no or have a small overlap. 6.4.2 Step 1: To obtain the maximum spatial average SAR value separately on all frequencies (frequency 1, frequency 2,... frequency x) of the station with multiband operation, according to established on item 5. 6.4.3 Step 2: For tests realized on equal conditions, examine to what extent the SAR distributions overlap by adding the scans area of spatial form, ie, point to point. 6.4.4 Step 3: If the maximum SAR peak resulting values of the added distribution are lower than 5% of the maximum peak SAR value, so the multiband SAR is equal to the greater value of the maximum spatial average SAR values. 6.5 Method 3 Mapping by the data calculation of the volumetric SAR. 6.5.1 This procedure uses area scan and zoom scan measurements together with interpolation and extrapolation for the data generation of the volumetric SAR. It can be applied on any case for obtaining multiband SAR. 6.5.2 Step 1: On each one of the frequencies, calculate the SAR volumetric distribution over the region projected by the area scan. The uncertainty of the used method must be calculated and registered. 6.5.3 Step 2: To add spatially the SAR volumetric distributions of all frequencies, using interpolation if necessary. 6.5.4 Step 3: To calculate the maximum spatial average SAR according to this Regulation through extrapolation of step 2. 6.6 Method 4 Mapping by volumetric scan 6.6.1 This procedure is the most accurate for the multiband SAR mapping. It can be applied on any case for obtaining multiband SAR. 6.6.2 Step 1: To determine a volumetric mesh that covers all the zoom scan of all frequencies (f1, f2,..., fx) previously measured. 6.6.3 Step 2: On each frequency (f1, f2,..., fx) to realize the zoom scan with the volumetric mesh determined on step 1. This measurement of the zoom scan must follow all the conditions of this Regulation, except on the volume s dimension. The measurements must be realized with a single frequency transmitting at a time.

6.6.4 Step 3: To add spatially the SAR distributions obtained on step 2 to obtain the added SAR distribution. To calculate the maximum multiband SAR of this distribution added according to this Regulation using extrapolation to determine the maximum spatial average SAR.
