Coverage Justification
EG46
ATT is proposing a new site , near the intersection of Amazon Drive and Fox Hollow Rd. in the city of Eugene, Oregon.
&
Exhibits A Exhibit B
This is an ATT service area that has weak signal coverage as shown in and also in even after the
&
EG46
addition of another proposed new sitenear Blanton Ridge. As can be seen, there is a large 4G LTE 700 MHz coverage
gap in all areas not shaded in green. While the target coverage area has voice grade service today, it does not have adequate
4G LTE service within the 700 MHz frequency band. As ATT’s technology improves and expands from 2G and 3G to 4G LTE,
&
the company is committed to meeting all wireless communication needs of its customers by delivering faster data speeds and
more reliable and expansive voice and data connections, whether its customers are in buildings, in vehicles, or outdoors.
ATT’s addition of new technology will also reduce the number of dropped calls and otherwise address its customers’ reported
&
service issues in the area.
The gap was determined as a result of analyzing a combination of customer complaints, service requests, and from RF
engineering design analysis. The planned service coverage improvement is mostly along Amazon Drive between HilyardStreet
and Snell Street, and the surrounding residential areas on the to East sides of Amazon Drive and also to the West going up the
hill along portion of Fox Hollow Rd..
Exhibit C
shows the projected coverage from the proposed candidate with an antenna tip height of 70 feet. This is the height
where an ATT wireless device can be reliably used to make and receive telephone calls and use data service in the presence
&
of varying signals.The proposed antenna tip height is the minimum necessary to fill the LTE 700 MHz coverage gap relative to
nearby complementary wireless facilities.
Exhibits D, E, and F
show the coverage from alternate site candidates on existing light standards near the proposed site. Two
antenna heights are required since antennas are flush mounted to pole and a second mounting height is needed to complete
the array. As illustrated in these exhibits, the alternate candidates are not adequate to fill the LTE 700 MHz coverage gap or
are otherwise not feasible.

Analyses of Alternate Site Locations
•AT&T Engineers evaluated 3
other candidates to see if the
towers would work
•Alternate#1 is an existing 30-ft
light standard near the proposed
site with an 18-ft permitted
extension. Coverage is shown
in Exhibits D[1,2]. Antenna
Alternate Site# 2
height is below the surrounding
tree height which significantly
Proposed
impacts the coverage of this
Candidate
site. It is ineffective as shown.
•Alternate#2 is an existing 45-ft
light standard near the proposed
Alternate Site# 1
site with an 18-ft permitted
extension. Coverage is shown
in Exhibits E[1,2]. Antenna
height is below the surrounding
tree height which significantly
impacts coverage of this site. It
is ineffective as shown.
•Alternate#3 is an existing 30-ft
light standard near an assisted
living center with an 18-ft
permitted extension. Coverage
is shown in Exhibits F[1,2].
Alternate Site# 3
Site location is too far south
which significantly impacts the
coverage of this site. It is
.
ineffective as shown
In addition to the radio frequency analysis of these sites,
AT&T considered factors like zoning, space for ground
equipment, and lease availability in determining the location
