RE: New Cingular Wireless PCS, LLC / AT&T Mobility Proposal Letter of Compliance — SN77
Edmonds Beach
Dear Reviewing Parties;
The existing AT&T Mobility facility proposed antennas swap out at 9227 Olympic View Dr, Edmonds,
WA 98026 will comply with the public maximum permissible exposure (MPE) levels set by the Federal
Communications Commission (FCC) in all publicly accessible areas. These FCC rules constitute a
national RF exposure standard that reflects the consensus agreement of the federal agencies charged with
protecting the public health and the environment.
To demonstrate compliance with the FCC radio frequency (RF) exposure limits, the power density
contributed by the ATT antenna facility has been predicted based on calculations provided by the FCC's
Office of Engineering Technology in OET Bulletin 65, Edition 97-01, released August 1997. This
determination is based on site -specific engineering data used to predict the RF power density in the
vicinity of the antennas and compares those levels with the public MPE limits (typically are less than 1 to
6% of the FCC Limit). The result of the predictive analysis (at the transmit power we plan on using)
demonstrates that the highest power density in a publicly accessible area is in compliance with FCC
requirements.
Sincerely,
Amy Wang
Radio Frequency (RF) Engineer
