tnxTower Report - version 8.0.7.5
3.1) Analysis Method
tnxTower (version 8.0.7.5), a commercially available analysis software package, was used to create a
three-dimensional model of the tower and calculate member stresses for various loading cases.
Selected output from the analysis is included in Appendix A. When applicable, Crown Castle has
calculated and provided the effective area for panel antennas using approved methods following the
intent of the TIA-222 Standard.
tnxTower was used to determine the loads on the modified structure. Additional calculations were
performed to determine the stresses in the pole and in the reinforcing elements. These calculations are
presented in Appendix C.
3.2) Assumptions
1) The tower and structures were maintained in accordance with the TIA-222 Standard.
2) The configuration of antennas, transmission cables, mounts and other appurtenances are as
specified in Tables 1 and 2, and the referenced drawings.
This analysis may be affected if any assumptions are not valid or have been made in error. Tower
Engineering Professionals should be notified to determine the effect on the structural integrity of the
tower.

Emissions Analysis for Site: CTNL815A
EBI Consulting was directed to analyze the proposed T-Mobile facility located at 557 Rte. 82 in Oakdale,
Connecticut for the purpose of determining whether the emissions from the Proposed T-Mobile
Antenna Installation located on this property are within specified federal limits.
All information used in this report was analyzed as a percentage of current Maximum Permissible Exposure
(% MPE) as listed in the FCC OET Bulletin 65 Edition 97-01and ANSI/IEEE Std C95.1. The FCC regulates
Maximum Permissible Exposure in units of microwatts per square centimeter (µW/cm2). The number of
µW/cm2 calculated at each sample point is called the power density. The exposure limit for power density
varies depending upon the frequencies being utilized. Wireless Carriers and Paging Services use different
frequency bands each with different exposure limits; therefore, it is necessary to report results and limits
in terms of percent MPE rather than power density.
All results were compared to the FCC (Federal Communications Commission) radio frequency exposure
rules, 47 CFR 1.1307(b)(1) – (b)(3), to determine compliance with the Maximum Permissible Exposure
(MPE) limits for General Population/Uncontrolled environments as defined below.
General population/uncontrolled exposure limits apply to situations in which the general population may
be exposed or in which persons who are exposed as a consequence of their employment may not be
made fully aware of the potential for exposure or cannot exercise control over their exposure. Therefore,
members of the general population would always be considered under this category when exposure is not
employment related, for example, in the case of a telecommunications tower that exposes persons in a
nearby residential area.
Public exposure to radio frequencies is regulated and enforced in units of microwatts per square
centimeter (W/cm2). The general population exposure limits for the 600 MHz and 700 MHz frequency
bands are approximately 400 W/cm2 and 467 W/cm2, respectively. The general population exposure
limit for the 1900 MHz (PCS), 2100 MHz (AWS) and 11 GHz frequency bands is 1000 W/cm2. Because
each carrier will be using different frequency bands, and each frequency band has different exposure limits,
it is necessary to report percent of MPE rather than power density.
Occupational/controlled exposure limits apply to situations in which persons are exposed as a
consequence of their employment and in which those persons who are exposed have been made fully
aware of the potential for exposure and can exercise control over their exposure.
Occupational/controlled exposure limits also apply where exposure is of a transient nature as a result of
incidental passage through a location where exposure levels may be above general population/uncontrolled
limits (see below), as long as the exposed person has been made fully aware of the potential for exposure
and can exercise control over his or her exposure by leaving the area or by some other appropriate
means.
Additional details can be found in FCC OET 65.
CALCULATIONS
Calculations were done for the proposed T-Mobile Wireless antenna facility located at 557 Rte. 82 in
Oakdale, Connecticut using the equipment information listed below. All calculations were performed per
the specifications under FCC OET 65. Since T-Mobile is proposing highly focused directional panel
antennas, which project most of the emitted energy out toward the horizon, all calculations were
performed assuming a lobe representing the maximum gain of the antenna per the antenna manufacturer’s
supplied specifications, minus 10 dB for directional panel antennas and 20 dB for highly focused parabolic
microwave dishes, was focused at the base of the tower. For this report, the sample point is the top of a
6-foot person standing at the base of the tower. For power density calculations, the broadcast footprint
of the AIR6449 antenna has been considered. Due to the beamforming nature of this antenna, the actual
beam locations vary depending on demand and are narrow in nature. Using the broadcast footprint
accounts for the potential location of beams at any given time.
For all calculations, all equipment was calculated using the following assumptions:
2 LTE channels (600 MHz Band) were considered for each sector of the proposed installation.
These Channels have a transmit power of 30 Watts per Channel.
1 NR channel (600 MHz Band) was considered for each sector of the proposed installation.
This Channel has a transmit power of 80 Watts.
2 LTE channels (700 MHz Band) were considered for each sector of the proposed installation.
These Channels have a transmit power of 30 Watts per Channel.
4 GSM channels (PCS Band - 1900 MHz) were considered for each sector of the proposed
installation. These Channels have a transmit power of 30 Watts per Channel.
2 LTE channels (PCS Band - 1900 MHz) were considered for each sector of the proposed
installation. These Channels have a transmit power of 60 Watts per Channel.
2 LTE channels (AWS Band – 2100 MHz) were considered for each sector of the proposed
installation. These Channels have a transmit power of 60 Watts per Channel.
1 LTE channel (BRS Band - 2500 MHz) was considered for each sector of the proposed
installation. This Channel has a transmit power of 120 Watts.
1 NR channel (BRS Band - 2500 MHz) was considered for each sector of the proposed
installation. This Channel has a transmit power of 120 Watts.
All radios at the proposed installation were considered to be running at full power and were
uncombined in their RF transmissions paths per carrier prescribed configuration. Per FCC
OET Bulletin No. 65 - Edition 97-01 recommendations to achieve the maximum anticipated
value at each sample point, all power levels emitting from the proposed antenna installation
are increased by a factor of 2.56 to account for possible in-phase reflections from the
surrounding environment. This is rarely the case, and if so, is never continuous.
For the following calculations, the sample point was the top of a 6-foot person standing at the
base of the tower. The maximum gain of the antenna per the antenna manufacturer’s supplied
specifications, minus 10 dB for directional panel antennas and 20 dB for highly focused
parabolic microwave dishes, was used in this direction. This value is a very conservative
estimate as gain reductions for these particular antennas are typically much higher in this
direction.
The antennas used in this modeling are the RFS APX16DWV-16DWV-S-E-A20 for the 2100
MHz channel(s), the RFS APXVAALL24_43-U-NA20 for the 600 MHz / 600 MHz / 700 MHz
/ 1900 MHz / 1900 MHz channel(s), the Ericsson AIR 6449 for the 2500 MHz / 2500 MHz
channel(s) in Sector A, the RFS APX16DWV-16DWV-S-E-A20 for the 2100 MHz channel(s),
the RFS APXVAALL24_43-U-NA20 for the 600 MHz / 600 MHz / 700 MHz / 1900 MHz /
1900 MHz channel(s), the Ericsson AIR 6449 for the 2500 MHz / 2500 MHz channel(s) in
Sector B, the RFS APX16DWV-16DWV-S-E-A20 for the 2100 MHz channel(s), the RFS
APXVAALL24_43-U-NA20 for the 600 MHz / 600 MHz / 700 MHz / 1900 MHz / 1900 MHz
channel(s), the Ericsson AIR 6449 for the 2500 MHz / 2500 MHz channel(s) in Sector C. This
is based on feedback from the carrier with regard to anticipated antenna selection. All
Antenna gain values and associated transmit power levels are shown in the Site Inventory and
Power Data table below. The maximum gain of the antenna per the antenna manufacturer’s
supplied specifications, minus 10 dB for directional panel antennas and 20 dB for highly focused
parabolic microwave dishes, was used for all calculations. This value is a very conservative
estimate as gain reductions for these particular antennas are typically much higher in this
direction.
The antenna mounting height centerline of the proposed antennas is 180 feet above ground
level (AGL).
Emissions values for additional carriers were taken from the Connecticut Siting Council active
database. Values in this database are provided by the individual carriers themselves.
All calculations were done with respect to uncontrolled / general population threshold limits.

Summary
All calculations performed for this analysis yielded results that were within the allowable limits for general
population exposure to RF Emissions.
The anticipated maximum composite contributions from the T-Mobile facility as well as the site composite
emissions value with regards to compliance with FCC’s allowable limits for general population exposure
to RF Emissions are shown here:

Sector C: 4.26%
T-Mobile Maximum
MPE % (Sector A): 4.26%
Site Total: 12.52%
Site Compliance Status: COMPLIANT
The anticipated composite MPE value for this site assuming all carriers present is 12.52% of the allowable
FCC established general population limit sampled at the ground level. This is based upon values listed in
the Connecticut Siting Council database for existing carrier emissions.
FCC guidelines state that if a site is found to be out of compliance (over allowable thresholds), that carriers
over a 5% contribution to the composite value will require measures to bring the site into compliance.
For this facility, the composite values calculated were well within the allowable 100% threshold standard
per the federal government.
