LLT167 01 18 May 2010 Page 1 of 2 QP4016 07- Tech Note Template Technical Note Subject: FCC Submission - Telecell RF Radiation Exposure Levels Date: 18 May 2010 Document ref: LLT167 01 1 Summary This document outlines RF radiation exposure level calculations for the NEMA and Conduit Telecells. Levels are specified as a power density. Limits are those defined in FCC § 1.1310 Radio frequency radiation exposure limits. In summary, the RF radiation exposure levels at a distance of 20 cm are below the specified FCC limits. 2 FCC § 1.1310 Limits 2.1 Limits for Occupational/Controlled Exposures This is appropriate for the Telecells since they are deployed by trained personnel and fixed to the top of streetlight luminaires. Limit: 300 lim f PD= mW/cm 2 , where f is the frequency in MHz. At the minimum frequency of 910.5 MHz, the limit is 3.03 mW/cm 2 . 3 RF Radiated Exposure Calculations 3.1 Power Density Expression The power density, PD, at a range R from the transmitter with an effective isotropic radiated power EIRP, is given by: 2 4R EIRP PD π =. To calculate the closest range at which the power density reaches the FCC limits, the following expression is used. lim 4PD EIRP R π = . 3.1.1 Power Density at 20 cm A worst case EIRP of 100 mW is assumed for the Telecell. At 20 cm, the power density is 0.02 mW/cm 2 , which is below the FCC limit of 3.03 mW/cm 2 . This is based on a duty cycle of 100%. However, during normal operation, the transmit duty cycle will typically be less than 1% when averaged over a 30 minute period which will mean that in practice the averaged power density will be closer to 0.0002mW/ cm 2 . LLT167 01 18 May 2010 Page 2 of 2 QP4016 07- Tech Note Template 3.1.2 Minimum safe distance Assuming a worst case EIRP of 100mW and a duty cycle of 1%, the power density meets the FCC limit at a distance of 0.16 cm.
