Executive SummaryOn January 10, 2009, Pinnacle Telecom Group (PTG) performed on-site

measurements of radiofrequency (RF) levels associated with a Sprint wireless

base station antenna operation located at 5411 Amboy Road, Staten Island, NY.

The site is the Our Lady Star of the Sea School and Church. Sprint refers to the

site by the code NY61XC174B and its directional panel antennas are mounted

on the roof of the gymnasium area of the school.

The purpose of the measurements was to assess and document compliance with

the applicable Federal Communications Commission (FCC) limit for maximum

permissible exposure (MPE) of the general public to the RF emissions from

antennas.

Measurements were performed on the school grounds as well as inside the

school. The equipment used to perform the measurements automatically

registers the effects from all RF sources in the area, not just the Sprint antennas.

The results of the measurements expressed as simple percentages of the FCC

MPE limit were as follows:

On the school grounds, the highest measured RF level was 1.5 percent of

the FCC MPE limit; in other words, the highest RF level is 66 times below

the FCC limit.

Inside the school, the highest measured RF level was 2.5 percent of the

FCC MPE limit; in other words, the highest RF level is 40 times below the

FCC limit.

The results of the measurements demonstrate compliance with the FCC limit. In

addition, an on/off test was performed to assess whether the RF effects from

the Sprint antennas were incrementally significant. The result of that test

demonstrated that there were no measurable differences in the RF levels with

the Sprint transmitters turned on versus turned off.

OverviewOn-site RF measurements were performed at the subject site to assess and

document compliance with the FCC MPE limit to the RF emissions from the

antennas. The MPE limit in question applies to uncontrolled exposure of the

general public what the FCC terms the general population MPE limit.

At the time the measurements were taken, a new church was under construction,

replacing the older church, on which had been cellular base station antenna

operations for other wireless service providers. These operations have been

relocated to two nearby buildings on Huguenot Street, immediately west of the

school property (approximately 230 feet from the school). The new church is in

the same location as the old church.

Measurements of RF levels were taken on the grounds of the property around

the school building, as well as inside the school in the classrooms, the corridors

and the gymnasiums.

The results of a compliance assessment can be described in laymans terms by

expressing the measured RF levels as simple percentages of the FCC MPE limit.

If the normalized reference for that limit is 100 percent, then measured RF levels

higher than 100 percent indicate the MPE limit is exceeded and there is a need

to mitigate the potential exposure. On the other hand, measured RF levels

consistently below 100 percent serve as a clear and sufficient demonstration of

compliance with the MPE limit.

The measurement equipment used by PTG provides automatic readouts of the

RF levels as percentages of the FCCs limit. The equipment is broadband,

covering a frequency range from 300 kHz to 50 GHz, and reflects the frequency-

shaping of the FCCs MPE limit (i.e., the different MPE values applicable to

different frequency ranges see Appendix B). The measurement results

automatically reflect the cumulative effects of all RF sources in the area, not just

the antennas that may be the intended subject of the compliance demonstration.

At the specific request of Sprints landlord, Our Lady Star of the Sea, Stewart

Maurer, Ph.D. and Professional Engineer, performed measurements at the same

time, in the same areas of interest, and under the same conditions. The

measurement equipment used by Dr. Maurer reported RF levels in the form of

raw field strength (volts/meter), and the equipment was not sensitive to the

frequency-shaped nature of the FCC MPE limit. Nevertheless, Dr. Maurer

agreed that his measurement results demonstrated compliance, and by

comfortable margins. We understand Dr. Maurer will be issuing a separate

report describing the results of his measurements and the related compliance

analysis.

The remainder of this report provides information on the site, a description of the

measurement equipment and procedure, the results of the measurement in each

area of interest, and an analysis of those results with respect to FCC compliance.

In addition, three appendices are included. Appendix A provides photographs of

the site. Appendix B provides background on the FCC MPE limit, along with a

list of references on compliance. Appendix C provides a summary of the expert

qualifications of the individual certifying FCC compliance for the subject antenna

site.

Site DescriptionSprint operates directional panel antennas at the site, arrayed in three sectors

with each sector pointing in a different direction. The antennas are mounted on

the roof of the schools gymnasium areas, mounted at and above the parapet

wall, facing away from the roof, approximately 34 feet above ground level.

During the site visit, we observed that there are other cellular antenna operationson the rooftops of two buildings west of the school property, approximately 230

feet from the school. The directional panel antennas are all mounted

approximately 30 feet above ground level.

Measurement Equipment and ProcedureThe RF measurements by PTG were performed using a Narda model 8722 RF

probe and Narda model 8715 RF meter. Both the probe and meter are capable

of broadband RF measurements, covering a range of 300 kHz to 50 GHz.

The equipment is calibrated by the manufacturer annually (as recommended),

with the most recent calibration having been performed in September 2008.

Measurements of RF levels were performed in the accessible areas of interest

around the site. The measurements were taken in a manner consistent with

training provided by the equipment manufacturer, including the RF Field

Measurements for Antenna Sites videotape, developed by Richard Tell

Associates and included as part of the Narda equipment package.

Measurement ResultsThe results of the measurements taken on the grounds of the school, expressed

as a percentage of the FCC general population MPE limit, are overlaid on the

aerial photograph of the site on the next page. The letters A, B and C overlaid onthe upper center of the photograph depict the locations of the Sprint antennas on

the roof of the schools gymnasiums. The triangles overlaid on the lower left of

the photograph depict the locations of the other nearby cellular antenna

operations on the rooftops of two buildings adjacent to the school property.

Note that the photograph, taken from the Google Earth website, was taken

before the Sprint antennas were on the site and while the old church (noted in

the photo) still existed. The photograph does provide, though, a spatial referencefor the site.

The maximum measured RF level on the grounds around the school buildings,

whether the base station antennas were on or off, was 1.5 percent of the FCC

general population MPE limit, equivalent to 66 times below the limit.

Measurements of RF levels were also performed in various areas inside the

school building. The results of these measurements are listed in the table on the

next page that lists the locations where the measurements were taken and themaximum measured RF level in each area. Once again, the measurement

results are expressed as a percentage of the FCC general population MPE limit.

Compliance ConclusionThe results of the on-site measurements in all areas of interest showed that the

RF levels were all below the 100-percent reference for MPE compliance.

The results of the measurements provide a clear demonstration that the Sprint

antenna operation satisfies the FCC compliance requirements.

Appendix B: Background on the FCC MPE LimitAs directed by the Telecommunications Act of 1996, the FCC has established alimit for maximum continuous human exposure to RF fields.

The FCC maximum permissible exposure (MPE) limit represent the consensus offederal agencies and independent experts responsible for RF safety matters.Those agencies include the National Council on Radiation Protection andMeasurements (NCRP), the Occupational Safety and Health Administration(OSHA), the National Institute for Occupational Safety and Health (NIOSH), theAmerican National Standards Institute (ANSI), the Environmental ProtectionAgency (EPA), and the Food and Drug Administration (FDA). In formulating itsguidelines, the FCC also considered input from the public and technicalcommunity notably the Institute of Electrical and Electronics Engineers (IEEE).

The FCC RF exposure guidelines are incorporated in Section 1.301 et seqof itsRules and Regulations (47 CFR 1.1301-1.1310). Those guidelines specify MPE

limits for both occupational and general population exposure.

The specified continuous exposure MPE limits are based on known variation ofhuman body susceptibility in different frequency ranges, and a SpecificAbsorption Rate (SAR) of 4 watts per kilogram, which is universally considered toaccurately represent human capacity to dissipate incident RF energy (in the formof heat). The occupational MPE guidelines incorporate a safety factor of 10 orgreater with respect to RF levels known to represent a health hazard, and anadditional safety factor of five is applied to the MPE limits for general populationexposure. Thus, the general population MPE limit has a built-in safety factor ofmore than 50. Continuous exposure at levels equal to or below the applicableMPE limits is considered to result in no adverse health effects on humans.

The reason for two tiers of MPE limits is based on an understanding andassumption that members of the general public are unlikely to have hadappropriate RF safety training and may not be aware of the exposures theyreceive; occupational exposure in controlled environments, on the other hand, isassumed to involve individuals who have had such training, are aware of theexposures, and know how to maintain a safe personal work environment.

The FCCs RF exposure limits are expressed in two equivalent forms, usingalternative units of field strength (expressed in volts per meter, or V/m), andpower density (expressed in milliwatts per square centimeter, or mW/cm2). Thetable on the next page lists the FCC limits for both occupational and general

population exposures, using the mW/cm2

reference, for the different radiofrequency ranges.

1,500 - 100,000 5.0 1.0

The diagram below provides a graphical illustration of both the FCCs

occupational and general population MPE limits.

Because the FCCs RF exposure limits are frequency-shaped, the exact MPElimits applicable to the instant situation depend on the frequency range used bythe systems of interest.

The most appropriate method of determining RF compliance is to assess the RFpower density attributable to a particular system and compare that to the MPE

limit applicable to the operating frequency in question. The result is usuallyexpressed as a percentage of the MPE limit.

For potential exposure from multiple systems, the respective percentages of theMPE limits are added, and the total percentage compared to 100 (percent of thelimit). If the result is less than 100, the total exposure is in compliance; if it is

more than 100, exposure mitigation measures are necessary to achievecompliance.
