AZAD RIM,being duly sworn, deposes and says:
1. I am a radio frequency engineer for New Cingular Wireless PCS, LLC
(hereinafter "AT&T"). As a radio frequency engineer, I am trained to identify service
deficiencies in AT&T's wireless telecommunications network and to evaluate the ability of
proposed antenna sites to remedy these service deficiencies. I am fully familiar with AT&T's
wireless telecommunications network in Suffolk County.
2. I submit this affidavit in support of AT&T's application for approval to install a
wireless telecommunications facility at the Premises. Pursuant to this application, the applicant
requests approval to erect a telecommunications monopole, with antennas therein, and install its
related equipment as depicted in the plans submitted herewith.
3. AT&T is considered a public utility for zoning purposes under the laws of the
State of New York and is licensed by the Federal Communications Commission to serve the
public within Suffolk County and throughout much of the United States. AT&T strives to
provide reliable service throughout its licensed coverage area.
4. At present, there is a substantial service gap in AT&T's wireless network
coverage in the vicinity of the proposed site. A service gap exists if the user of an AT&T mobile
telephone cannot reliably transmit, receive or maintain a voice or data connection. The service
gap in coverage that now exists in the vicinity of the proposed site prevents AT&T from
providing reliable service in the area. This unreliability represents an inconvenience to users of
AT&T's services and can have serious consequences during times of emergency or disaster.
5. In order to understand why the proposed antenna site is needed, it is necessary to
understand how AT&T's system works from an engineering standpoint. AT&T's wireless
telecommunications system is designed so that low powered base stations are strategically
located at determined distances apart and at predetermined heights. Due to such factors as hills,
valleys, trees, buildings, and other physical obstructions and due to the nature of radio waves,
each coverage area or"cell"is irregularly shaped. With sufficient signal strength from each base
station, the AT&T user can reliably transmit, receive or maintain voice or data connections. The
sites are ordinarily engineered to cover a limited area so that an antenna facility will cover only
the area surrounding it but will not interfere with other sites in the system.
6. AT&T has established design criteria so that its wireless network will provide
reliable wireless service to its customers, whether those customers are on the street, in a vehicle,
or in a building. Providing reliable service to AT&T's customers within vehicles and buildings
is critical for AT&T to provide the quality of wireless service that customers demand and
successfully compete with other wireless providers.
7. To meet customer demands and expectations, AT&T strives to provide both In-
Vehicle (or In-Car) coverage and In-Building coverage. These coverage levels represent the
2
minimum signal strength and reliability of service needed to transmit, receive or maintain a voice
or data connection at the mobile handset as the environment changes.
8. To provide these levels of coverage, AT&T has scientifically determined the
strength of the wireless signal ("signal strength") necessary to provide In-Vehicle coverage and
In-Building coverage. Because wireless signals are attenuated (i.e. degraded or partially
blocked) by obstructions such as trees, automobile windows, automobile sheet metal, and
building materials such as wood, brick and metal, a wireless signal must be of sufficient strength
in the ambient environment (i.e. outside with no obstructions) to reliably penetrate into
automobiles and buildings.
9. Wireless signal strength is measured on a logarithmic power scale referenced to 1
milli-watt of power. Signal strength levels less than 1 milli-watt being negative. The smaller the
negative dBm number, the stronger the signal. For example, -75dBm is a stronger signal level
than —85dBm. An ambient signal level of—95dBm would provide reliable On-Street coverage.
AT&T's system requires an ambient signal level of —85dBm to provide reliable In-Vehicle
coverage, and an ambient signal level of —75dBm to provide reliable In-Building coverage.
These signal level requirements provide the basis for AT&T's design criteria.
10. AT&T's design criteria for wireless facilities serving an area are based upon
providing 95% reliable signal over a site's coverage area to ensure reliable service for customers.
This standard reflects a business judgment that 100% reliability is an unrealistic goal at this time
due to financial, technical and environmental constraints. A 95% level of reliability is consistent
with the level of service provided by AT&T's competitors and is the standard in the industry.
Providing service at this level allows AT&T to satisfy customers' demands and compete on an
equal footing with competitors serving the market.
3
11. To achieve the 95% reliable design goal, AT&T conducts extensive analysis
based upon AT&T's technology and the area served.
12. In order to eliminate the service deficiency in a particular area, AT&T performs
signal propagation studies to determine the height and location of the needed cell site. Based on
its studies, AT&T determined that an antenna facility would have to be established within a
narrowly defined search area in order to remedy the service gap in question. In this case, we
determined that the installation of the proposed facility will allow AT&T to provide reliable
service in the vicinity of the Premises.
13. The proposed antennas must be affixed at least as high as those depicted on the
plans submitted herewith in order to ensure that reliable service can be afforded to AT&T users
in the vicinity of the site. The location and height of the antennas is determined by some or all of
the following factors: availability of existing structures, willingness of property owners to enter
into leases, drive test data, location of existing antenna sites in the area, topography in the
surrounding area, land cover features in the area such as buildings and foliage, and the results
provided by computer propagation software that enables radio frequency engineers to predict the
anticipated signal propagation at a given height and location.
14. In order to illustrate the effect that the proposed site would have on coverage in its
vicinity, propagation maps are submitted herewith demonstrating the different coverage levels
summarized above. The maps depict the areas presently enjoying reliable service in the vicinity,
and the area to be served by the proposed site. As the maps indicate, the proposed facility is of
vital importance to AT&T 's efforts to provide reliable service to the area in question. Unless
this application is granted, AT&T will be unable to provide reliable service in the vicinity of the
Premises.

15. The antennas proposed will not interfere with radio or television service or public
safety telecommunications in the surrounding area.
