18 4.3.1 Maximum Transmit Power Test Requirement(s): ETSI EN , Clause 4.3.1: Definition The maximum transmit power is defined as the maximum isotropic radiated power of the equipment Limit The equivalent isotropic radiated power (e.i.r.p.) shall be equal to or less than -10 dbw (100 mw). This limit shall apply for any combination of power level and intended antenna assembly. Test Procedure: Measurements were carried out in all modulations available and at the low, mid and high channels of the transmit band. Both normal and extreme test conditions were observed. The EIRP was calculated from the following equation: P = A + G + 10 log (1/x); where A is the measured power, x is the duty cycle and G is the antenna assembly gain. Test Results: The EUT as tested was found compliant with the specified limits in clause Test Engineer: Manasi Bhandiwad Test Date: 04/21/11 EUT Attenuator Spectrum Analyzer Figure 2.

22 4.3.2 Maximum EIRP Spectral Density Test Requirement(s): ETSI EN Section 4.3.2: Definition The maximum EIRP spectral density is defined as the highest EIRP level in Watts per Hertz generated by the transmitter within the power envelope Limit For wide band modulations other than FHSS (e.g. DSSS, OFDM, etc.), the maximum EIRP spectral density is limited to 10 mw per MHz. Test Procedure: Option 1 was used to measure the power (A). The maximum spectral power density EIRP was determined using the following equation: P = A + G + 10 log (1/x); where A is the measured power, x is the duty cycle and G is the antenna assembly gain. Cable loss has been pre-programmed into SA. Test Results: The EUT as tested was found compliant with the specified limits of Clause Maximum SPD <= 10mW (10 dbm) per MHz EIRP in Normal Test Condition, SPD = Spectral Power Density.

30 4.3.3 Frequency Range Test Requirement(s): EN Clause 4.3.3: Definition The frequency range of the equipment is determined by the lowest and highest frequencies occupied by the spectrum envelope. fh is the highest frequency of the spectrum envelope: it is the frequency furthest above the frequency of maximum power where the EIRP spectral density drops below the level of -80 dbm/hz (-30 dbm if measured in a 100 khz bandwidth). fl is the lowest frequency of the spectrum envelope; it is the frequency furthest below the frequency of maximum power where the EIRP spectral density drops below the level of - 80 dbm/hz (or -30 dbm if measured in a 100 khz bandwidth). For a given operating frequency, the width of the spectrum envelope is (fh - fl). In equipment that allows adjustment or selection of different operating frequencies, the power envelope takes up different positions in the allocated band. The frequency range is determined by the lowest value of fl and the highest value of fh resulting from the adjustment of the equipment to the lowest and highest operating frequencies Limit For all equipment the frequency range shall lie within the band 2.4 GHz to GHz (fl > 2.4 GHz and fh < GHz). Test Procedure: Option 1 (using a spectrum analyzer average detector) was used to perform testing. A positive 5 db offset was programmed into SA to account for 5 dbi antenna. Test Results: The EUT as tested was found compliant with the specified limits of Clause Test Engineer: Manasi Bhandiwad Test Date: 04/21/11 EUT Attenuator Spectrum Analyzer Figure 4.

Test Results: The EUT facilitates medium access protocol and therefore is compliant with the requirements of Clause Test Engineer: Manasi Bhandiwad Test Date: 04/11/11 MET Report: EMC30563-ETS , MET Laboratories, Inc. Page 24 of 41

33 4.3.6 Transmitter Spurious Emissions - Radiated Test Requirement(s): EN , Clause 4.3.6: Definition Transmitter spurious emissions are emissions outside the frequency range(s) of the equipment as defined in Clause when the equipment is in Transmit mode and/or in Standby mode Limit The spurious emissions of the transmitter shall not exceed the values in Table 15 And Table 16 and in the indicated bands. Frequency Range Limit when operating Limit when in standby 30 MHz to 1 GHz -36 dbm -57 dbm above 1 GHz to 12,75 GHz -30 dbm -47 dbm 1,8 GHz to 1,9 GHz 5,15 GHz to 5,3 GHz -47 dbm -47 dbm Table 15. Transmitter limits for narrowband spurious emissions The above limit values apply to narrowband emissions, e.g. as caused by local oscillator leakage. The measurement bandwidth for such emissions may be as small as necessary to achieve a reliable measurement result. Wideband emissions shall not exceed the values given in Table 16 Frequency Range Limit when operating Limit when in standby 30 MHz to 1 GHz -86 dbm -107 dbm/hz above 1 GHz to 12,75 GHz 1,8 GHz to 1,9 GHz 5,15 GHz to 5,3 GHz -80 dbm -97 dbm/hz -97 dbm -97 dbm/hz Table 16. Transmitter limits for wideband spurious emissions Test Procedure: The EUT was placed on a 1.5m high wooden table inside a semi-anechoic chamber. The measurements were performed using normal operation of the equipment. The method of testing, test conditions, and test procedures of Annex B were used. The frequencies and amplitudes of field strengths were recorded for reference during final measurements. The EUT was set to transmit at its highest output power at both the low and high channels of the transmit band as well as all applicable modulations. The receive antenna was adjusted in order to find the maximum emission. The table was also rotated about Both vertical and horizontal polarizations were used to determine the maximum emission. MET Report: EMC30563-ETS , MET Laboratories, Inc. Page 25 of 41

34 Measurements were made at 1m. The plots have been corrected for antenna correction factor and cable loss. A field strength measurement was made at 1m and then converted to an EIRP measurement using the formula: EIRP = E 0 = 20logD E 0 = Field Strength in dbuv/m D = measurement distance in meters The plots have been corrected to take into account all these conversions. Therefore, the following plots show the absolute ERP values compared to the limit. Test Results: The EUT as tested was found compliant with the specified limits of Clause Test Engineer: Jeff Pratt Test Date: 03/10/11 EUT Attenuator Spectrum Analyzer Figure 5.

42 4.3.7 Receiver Spurious Emissions Radiated Test Requirement(s): Definition Receiver spurious emissions are emissions at any frequency when the equipment is in received mode Limit The spurious emissions of the receiver shall not exceed the values in tables Table 17 and Table 18 and in the indicated bands. Frequency Range Limit 30 MHz to 1 GHz -57 dbm above 1 GHz to 12,75 GHz -47 dbm Table 17. Narrowband spurious emission limits for receivers The above limit values apply to narrowband emissions, e.g. as caused by local oscillator leakage. The measurement bandwidth for such emissions may be as small as necessary to get a reliable measurement result. Wideband emissions shall not exceed the values given in Table 18 Frequency Range Limit 30 MHz to 1 GHz -107dBm/Hz above 1 GHz to 12,75 GHz -97 dbm/hz Table 18. Wideband spurious emission limits for receivers MET Report: EMC30563-ETS , MET Laboratories, Inc. Page 34 of 41

43 Test Procedure: The EUT was placed on a 1.5m high wooden table inside a semi-anechoic chamber. The measurements were performed using normal operation of the equipment. The method of testing, test conditions, and test procedures of Annex B were used. The frequencies and amplitudes of field strengths were recorded for reference during final measurements. The EUT was set to transmit at its highest output power at both the low and high channels of the transmit band as well as all applicable modulations. The receive antenna was adjusted in order to find the maximum emission. The table was also rotated about Both vertical and horizontal polarizations were used to determine the maximum emission. Measurements were made at 1m. The plots have been corrected for antenna correction factor and cable loss. A field strength measurement was made at 1m and then converted to an EIRP measurement using the formula: EIRP = E 0 = 20logD E 0 = Field Strength in dbuv/m D = measurement distance in meters The plot has been corrected to take into account all these conversions. Therefore, the following plots show the absolute ERP values compared to the limit. Test Results: The EUT as tested was found compliant with the specified limits of Clause Test Engineer: Jeff Pratt Test Date: 03/10/11 EUT Attenuator Spectrum Analyzer Figure 6.
