Evaluation of RF Exposure for SL9090 Wireless Modem as a Mobile Device In this application we seek modular approval to the SL9090 wireless modem for use in mobile configuration. Part I: FCC requirement Based on the FCC OET Bulletin 65 Supplement C and 47 CFR §2.1091, we have concluded that the SL9090 will comply with the FCC rules on RF exposure for mobile devices if the antenna gain does not exceed 7.5 dBi in cellular band and 3.5 dBi in PCS band. The following analysis will demonstrate such compliance. The analysis will be done in two US bands. Operation in cellular band (824 – 849 MHz) The peak conducted output power of SL9090 in Cellular band is 32.61 dBm. Take the worst case as an example, in which an antenna with 7.5 dBi gain is used. The resulted power density at a distance of 20 cm can be deducted as follows: EIRP = Pcond + 7.5 Power Density = EIRP*DutyCycle/(4πR 2 ) The table below shows the different MPE levels in different time slot configurations: Max Pcond (dBm) Max EIRP (dBm) Max EIRP (mW) Dute Cycle MPE (mW/ cm 2 ) 1 Time Slot 32.44 39.94 9862.79 12.5% 0.245 2 Time Slots 32.61 40.11 10256.52 25% 0.510 The MPE limit for General Population/Uncontrolled Exposure is shown in the FCC OET Bulletin 65 Supplement C and can be calculated as follows: MPE limit = 824/1500 = 0.55 mW/cm 2 As we can see the resulted power density is below the MPE limit, therefore SL9090 in Cellular band is compliant with the FCC rules on RF exposure. Operation in PCS band (1850 – 1910 MHz) The peak conducted output power of SL9090 in PCS band is 29.4 dBm. Take the worst case as an example, in which an antenna with 3.5 dBi gain is used. The resulted ERP can be expressed as follows: ERP = 29.4 + 3.5 –2.15 = 30.75 dBm (1.19 W) < 3 W The FCC OET Bulletin 65 Supplement C states that mobile devices identified in 47 CFR §2.1091 that operate at frequencies above 1.5 GHz with an ERP of 3.0 watts or more are required to perform routine environmental evaluation for RF exposure prior to equipment authorization or use; otherwise, they are categorically excluded. As we can see this resulted ERP is below 3 W, therefore routine environmental evaluation for RF exposure prior to equipment authorization or use for SL9090 in PCS band is categorically excluded. Part II: IC requirement Power Density= 0.515m W/cm 2 =5.15W/ m 2 (Worse case) When operate in cellular band (824 – 849 MHz) if the device antenna gain does not exceed 7.5 dBi in cellular band. (Please list the power density calculation base on cellular peak power) Power Density= 0.097m W/cm 2 =0.97W/ m 2 (Worse case) When operate in PCS band (1850 – 1910 MHz) if the device antenna gain does not exceed 3.5 dBi in PCS band. (Please list the power density calculation base on PCS peak power) The table below shows the different MPE levels in different time slot configurations: Max Pcond (dBm) Max EIRP (dBm) Max EIRP (mW) Dute Cycle MPE (mW/ cm 2 ) 1 Time Slot 29.4 32.9 1949.84 12.5% 0.048 2 Time Slots 29.4 32.9 1949.84 25% 0.097 AS IC RSS-102 requirement, RF Field Strength Limits for Devices Used by the General Public (Uncontrolled Environment) listed below: Frequency Range (MHz) Electric Field (V/m rms) Magnetic Field (A/m rms) Power Density (W/ m 2 ) Averaging Time (minutes) 0.003-1 280 2.19 - 6 1-10 280/f 2.19/f - 6 10-30 28 2.19/f - 6 30-300 28 0.073 2* 6 300-1500 1.585 f 0.5 0.0042 f 0.5 f/150 6 1500-15000 61.4 0.163 10 6 15000-150000 61.4 0.163 10 616000/f 1.2 150000-300000 0.158 f 0.5 4.21 x 10-4 f 0.5 6.67 x 10-5 f 616000/f 1.2 Note: f is frequency in MHz. * Power density limit is applicable at frequencies greater than 100 MHz. The RF Field Strength limit for General Population/Uncontrolled Exposure is shown in the RSS- 102 and can be calculated as follows: Cellular band limit = 824/150 = 5.5 W/m 2 PCS band limit =10W/ m 2 As we can see the resulted power density is below the MPE limit, therefore SL9090 is compliant with the IC rules on RF exposure.

The temperature was set to -30°C and maintained to stabilize. After sufficient soak time, the transmitting frequency error was measured. The temperature was then increased by 10 degrees, maintained to stabilize, and the measurement was repeated. This procedure was repeated until +50°C is reached. Frequency metering included internal averaging of the 8960 to stabilize the reading. Reference power supply voltage for these tests is 3.6 volts.

It meets the frequency stability limit of less than 2.5ppm when supply voltage varies within the specified limits. Operation above or below these voltage limits is prohibited by firmware in order to prevent improper operation. 9.2 Test Procedure The EUT was connected to a DC Power Supply and a UMTS test set (CMU 200) with frequency error measurement capability. The power supply output was adjusted to the test voltage as measured at the input terminals to the device while transmitting. A voltmeter was used to confirm the terminal voltage. The peak frequency error is recorded (worst case). The test voltages are 3.4 volts to 4.2 volts. NOTE: Below 3.4V and above 4.2V, the device stops transmitting.
