Smart Meters - Public Service Commission

EIRP = PG
ERP = 1.64 EIRP
where:
EIRP = is equivalent (or effective) isotropically radiated power
referenced to an isotropic radiator
ERP = is equivalent (or effective) radiated power referenced to a
half-wave dipole radiator
Analysis input assumptions
1. SMART Meters [SK9AMI-4] have two RF transmitters (antennas)
and are the type of smart meters typically installed on most buildings.
They contain two antennas that transmit RF signals (916 MHz LAN
and 2405 MHz Zigbee). The antennas CAN transmit simultaneously,
and thus the maximum RF exposure is determined by the summation
of power densities (from the FCC Certification Exhibit titled RF
Exposure Report for FCC ID: SK9AMI-4).
Model SK9AMI-4 transmits on 915 MHz is designated as LAN
Antenna Gain for each model.
a. Transmitter Power Output (TPO) used is as shown on the grant
issued by the Telecommunications Certification Body (TCB).
b. Antenna gain in dBi (decibels compared to an isotropic
radiator) used comes from the ACS Certification Exhibit.
2. Collector Meters [SK9AMI-2A] have three RF transmitters (antennas)
