1.0 EXECUTIVE SUMMARY
An RF interference analysis was conducted to determine the feasibility of locating a Verizon
radio system on a tower that is in close proximity to an existing radio tower in Raymer, CO.
This analysis was necessary to ensure Verizon's facility using the 850/1900 MHz
cellular/PCS bands do not cause degradation to operational performance to the nearby radio
system and no performance degradation is experienced by the Verizon system.
The Weld County tower currently uses analog UHF and 850 MHz FDMA radio systems on
an approximate 170 foot tower. The proposed Verizon tower location is 200 feet at a 25
degree bearing from true north from the Weld County tower with a height of approximately
200 feet. A worst case analysis was performed that used Verizon's fully configured set of
radio systems in the 850/1900 MHz cellular/PCS bands for future growth.
The commercial radio frequency interference analysis software program called ComSitePlus
was used to perform the RF interference study. Analysis results predict that signal levels will
be sufficiently low to preclude harmful interference (1) From Verizon transmitters to the
Weld County receivers and (2) From Weld County transmitters to Verizon receivers.
Interference analysis included receiver performance degradation due to transmitter noise,
receiver desensitization and transmitter/receiver produced IM.
A summary of the RF interference analysis results is depicted in the following Table.

2.0 SITE DESCRIPTION
Currently, Weld County operates 5 transmitters in the 800 MHz band and 1 transmitter in the
460 MHz land mobile band on an approximately 170' tower. The antenna center lines are
150' and 160' respectively.
The proposed Verizon site is an approximate 200 foot tower in Raymer, CO that is a distance
of 200' with a 25 degree bearing from true north from the Weld County tower. The worst-
case Verizon configuration for future growth uses multiple transmitters and antennas in a 3-
sector configuration. This worst-case configuration uses 7 CDMA cellular transmitters, 6
CDMA PCS transmitters and 5 analog cellular transmitters on each sector. The antenna
center line is 191'.
2.1 System Parameters
The analysis considered the following 6 Weld County RF channels on the tower: 1 UHF (460
MHz) channel and 5 FDMA 860 MHz channels.
The analysis also considered the following 54 Verizon RF channels: 21 total CDMA
channels at 850 MHz, 18 total CDMA channels at 1900 MHz, and 15 total AMPS channels at
850 MHz.

3.0 RF INTERFERENCE
Radio Frequency (RF) interference may cause degradation in operational performance to
wireless voice operators or other wireless users (wireless data transmission) resulting in poor
voice call quality, dropped voice calls, or degraded data rates. In general, there are three
main types of interference mechanisms that cause RF interference, namely intermodulation
interference,transmitter noise, and receiver desensitization.
3.1 Intermodulation
Intermodulation interference occurs when two or more transmitters combine (mix) to create
an on-channel signal, causing interference to a single receiver. The mixing process takes
place as it passes through any non-linear junction, and can occur in an active radio stage (IF,
mixer) or a passive external bi-metallic junction. For example, active mixing can occur
inside any transmitter or receiver at a collocation site or a site in close proximity. Passive
mixing can occur in dissimilar metals, unclean interconnects, or other anodic effects such as
corroded antenna connector or rusty chain link fence.
,/i-ECC Page 5
Intermodulation is created through variations of the fundamental and harmonics of
frequencies that are added or subtracted as it is transmitted through an active or passive non-
linear junction. Intermodulation is the multiplication of one frequency by other frequencies.
Generally, the IM products are odd-order,meaning that source frequencies are combined
algebraically with an exponent of 3, 5, 7, etc...
FREQUENCY: 3RD ORDER EXAMPLE
Source Transmit Signals (2) F1,F2
Math Representation (a+b)3=a3 +2a2b+2ab2+b3
Mixing Products Resulting 3F1 , 3F2 ,2F1 -F2 ,2 F2 -F1
ComSitePlus, a commercial radio frequency interference analysis software tool, will take as
an input all the source frequencies which are among the strongest at the co-location site, and
calculate all the possible mixing products up to the order specified. The number of IM
products will increase dramatically as the order increases.
3.2 Transmitter Noise
A transmitter radiates energy both in and out of its designated operating frequency band. The
out of band energy (noise), if not properly filtered at the transmitter, can fall within the
passband of a nearby receiver causing a noise floor rise in the operating frequency band of
this receiver. To avoid a problem, the transmitter noise should not raise the noise floor by
more than 1dB.
3.3 Receiver Desensitization
Receiver desensitization occurs when an undesired signal from a transmitter is close to a
nearby receiver's operating frequency, and not adequately attenuated by the receive filters. If
this undesired signal is of sufficient amplitude, it can overdrive the LNA causing it to
compress into its nonlinear region and degrade sensitivity. To avoid a problem, the transmit
carrier should be received at least 10dB below the compression point of the receiver.
ATECS Page 6
4.0 ANALYSIS & RESULTS
The ComSitePlus computer program was used to perform the RF interference study. The
system parameters of each communication system shown in section 2 were manually entered
into ComSitePlus along with the default parameters defined in Table 3.

Table 3. ComSitePlus default settings
4.1 Transmitter/Receiver Intermodulation
The first step of the transmitter/receiver intermodulation analysis is the formation of an
intermodulation (IM) 'hit list'. Using formulas shown in Section 3.1, the ComSitePlus
program calculates the IM products created by the mixing of both transmitter and receiver
frequencies for each of the 60 transmitters and 60 receivers used in this analysis. When a
resulting IM frequency is sufficiently close to the frequency of a receiver, the program
reports a `hit'.
Next, an IM signal analysis is performed on each of the IM hit analysis studies. The
calculation is performed for both transmitter and receiver produced IM. This will determine
the magnitude (signal level) of each hit, whether the hit is located in the passband of a
receive frequency and whether the signal level of the in-band hit degrades the performance of
a receiver (i.e. IM signal level is greater than receiver sensitivity). The calculation is
performed for both transmitter and receiver produced IM products.
An IM Hit analysis was run for ls` through 5th order products with up to 4 transmitters at a
time. Results show that for combinations of up to four transmitter frequencies, 449,317 IM
hits of order 1 through 5 affect receiver frequencies of the communication systems.
IM Signal analysis levels were reviewed for all IM products that were located in the receiver
bands of all 60 receivers. Results demonstrate that all interference signal levels were below
i / &CS Page 7
Rx signal level minimums. Thus, ComSitePlus program predicts that all IM products
affecting the 54 Verizon receivers will be of sufficiently low levels to preclude harmful
interference. In addition, the ComSitePlus program predicts that all IM products affecting
the 6 receivers of the Weld County communication systems will be of sufficiently low levels
to preclude harmful interference, including contributions from Verizon transmitters and
receivers.
Appendix A shows the output of the IM Hit List summary as well as a sample analysis of a
5th Order IM product (at 840.02 MHz) that falls in a Verizon receiver band (CH510 with
center Rx frequency at 840.3 MHz)where the IM product signal level (-155.6 dBm) is below
the Verizon receiver sensitivity level (worst case-120 dBm).
4.2 Transmitter Noise/Receiver Densensitization
The Noise/Desensensitization analysis is performed on each of the IM Hit analysis studies.
This analysis determines whether any transmitter is of sufficient signal level to overdrive any
receiver LNA causing it to compress into its nonlinear region and degrade sensitivity. The
ComSitePlus program predicts that transmitter signal levels are not sufficient to cause
transmitter noise or receiver desensitization interference. Isolation attenuation provided by
the distance separation between each communication site location contributes to this result.
4.3 Harmonic Interference
Transmitter harmonics are integer multiples (2,3,4, ...) of the carrier frequency that are
potential sources of interference. These harmonics are produced by non-linearity of the
transmitter system, primarily the RF power amplifier. Transmit frequency multiples that do
not fall near the frequency of any receivers at the site are of little concern.
Harmonics of the Verizon and Weld County transmit frequencies do not fall near the
frequency of the receivers at the site. Therefore harmful interference as a result of harmonics
is not expected to occur.
4.4 Spurious Interference
Verizon's and Weld County's base station equipment is expected to adequately suppress out-
of-band spurious emissions so that harmful interference will not occur.
TECS Page 8
5.0 CONCLUSION
The commercial radio frequency interference analysis software program called ComSitePlus
was used to perform the RF interference study. Analysis results predict that signal levels will
be sufficiently low to preclude harmful interference (1) From Verizon transmitters to Weld
County receivers and (2) From Weld County transmitters to Verizon receivers. Interference
analysis included receiver performance degradation due to transmitter noise, receiver
desensitization and transmitter/receiver produced IM.
