9.1 RF Human Exposure - FDTD Analysis and SAR Testing
9.1.1 Applicable FCC Rules
FCC Subpart 24.51 - Applications for Type Approval of transmitters
operating within the PCS region must determine that the equipment
complies with IEEE C95.1-1991, “IEEE Standards for Safety Levels
with Respect to Human Exposure to Radio Frequency Electromagnetic
Fields, 3 kHz to 300 GHz” as measured using methods specified in
IEEE C95.3 - 1991, “Recommended Practice for the Measurement of
Potentially Hazardous Electromagnetic Fields - RF and Microwave.”
9.1.2 Typical Test Configuration
This MPE analysis was completed for a worse case situation, with a
typical roof top antenna (six feet high) PWAN Base Station installation.
Characteristics used for this typical MPE are shown in Table 9.1.
Each PWAN Base Station installed will include an MPE analysis with
data and required paperwork being stored and filed with the FCC as per
regulatory requirements.
9.1.3 Typical MPE Test Results
The PWAN Base Station meets the required FCC regulatory part 24
requirements as shown in the following figures. Figure 9.1 illustrates
horizontal distance versus power density, while Figure 9.2 provides
graphical data of horizontal distance versus uncontrolled MPE.
As shown in Table 9.2, a typical PWAN Base installation meets FCC
MPE requirements. Per regulations, all installations will include an
MPE analysis with data being stored and filed appropriately.
