Pyramid Communications FCC ID: LRUSVR-250V Report Number: R1012204-90 Page 10 of 26 FCC Part 90 Test Report 4 FCC §2.1091 - RF Exposure Information 4.1 Applicable Standards FCC §2.1091 (a) Requirements of this section are a consequence of Commission responsibilities under the National Environmental Policy Act to evaluate the environmental significance of its actions. See subpart I of part 1 of this chapter, in particular §1.1307(b). According to §1.1310 and §2.1091 RF exposure is calculated. Limits for Exposure Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3-3.0 614 1.63 *(100) 6 3.0-30 1842/f 4.89/f *(900/f 2 ) 6 30-300 61.4 0.163 1.0 6 300-1500 / / f/300 6 1500-100,00 / / 5.0 6 (B) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 842/f 2.19/f *(180/f 2 ) 30 30-300 27.5 0.073 0.2 30 300-1500 / / f/1500 30 1500-100,000 / / 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density Note 1 to Table 1: Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational/controlled limits apply provided he or she is made aware of the potential for exposure. Note 2 to Table 1: General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure. Pyramid Communications FCC ID: LRUSVR-250V Report Number: R1012204-90 Page 11 of 26 FCC Part 90 Test Report Antenna: The manufacturer does not specify an antenna. A typical vehicle antenna has a gain of 3 dBi was used with this device. This device has provisions for operation in a vehicle, or a fixed location . Operating Configuration and exposure conditions: Device category: Mobile per Part 2.1091 Environment: Controlled Exposure Typical use qualifies for a maximum duty cycle factor of 50%. The manufacturer also markets this device only for occupation use. MPE Prediction Predication of MPE limit at a given distance, Equation from OET Bulletin 65, Edition 97-01 S = PG/4πR² Where: S = power density P = power input to antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna Conclusion The device complies with the MPE requirements by providing a safe separation distance of 20 cm between the antenna, including any radiating structure, and any persons when normally operated. Maximum peak output power at antenna input terminal (dBm): 33.52 Maximum peak output power at antenna input terminal (mW): 2250 Maximum output power at antenna input terminal with 50% Duty Cycle (mW): 1125 Prediction distance (cm): 20 Prediction frequency (MHz): 160.1 Maximum Antenna Gain, typical (dBi): 3.0 Maximum Antenna Gain (numeric): 2.0 Power density of prediction frequency at 20 cm (mW/cm 2 ): 0.447 MPE limit for uncontrolled exposure at prediction frequency (mW/cm 2 ): 1.0
