Ref: phn-1151_000v001

Abstract

This document analyses the operating and installation requirements to ensure

limits for RF Exposure compliance are not exceeded by the PTP54500 and

PTP58300 range of products with integrated antennas. The guidelines in FCC

Bulletin 65 are used for the analysis.

MOTOROLA IN CONFIDENCE OPERATIONAL PARAMETERS OF THE PTP54500/PTP54300 PRODUCT 1 Scope The purpose of this brief working paper is to identify the RF power produced by the PTP54500/PTP54300 equipment under various operating conditions. This mean RF power plus the antenna gain used in specific installations identifies the effective power density (dBm/cm2) that is to be compared against allowed limits for human exposure.

MOTOROLA IN CONFIDENCE Maximum Transmit Power during the transmit period (total for both polarisations) for PTP54500/PTP54300 equipments in production is set to not exceed 5dBm to ensure that the Maximum EIRP requirement during the burst (27.76 dBm) is not exceeded when the product is used with the supplied integrated antenna (G = 23dBi). The PTP54500/PTP54300 equipments operate on a TDD basis using the same frequency for up/down link.

MOTOROLA IN CONFIDENCE In the case of PTP 54500/PTP54300 Channel BW = 15 MHz. Allowance for source-based time-averaging: Maximum Tx duty cycle = 50% or 3.0dB Allowed EIRP = 11 + 11.76 - Actual Antenna Gain + 6 + Actual Antenna Gain = 28.76 dBm EIRP used for MPE calculation = 27.78 -3.0 = 25.76 dBm or 376mW 5.
