6.0 Receiver Desensitization Analysis
Receiver desensitization interference occurs when an undesired signal from a nearby "011-frequency" transmitter is sufficiently close to a receiver's operating frequency. The signal may get' through the RF selectivity of the receiver. If this undesired signal is of sufficient amplitude, the receiver's critical voltage and current levels are altered and the performance of the receiver is degraded at its operating frequency. The gain of the receiver is reduced, thereby reducing the performance of the receiver.
A transmitter can be operating several megahertz away from the receiver frequency and/or its antenna can be located several thousand feet from the receiver's antenna and still cause interference.
The analysis predicts each transmitter's signal level present at the input of each receiver. It takes into account the transmitter's power output, frequency separation, transmission line losses, filters, duplexers, combiners, isolators, multi-couplers and other RF devices that are present in both systems. Additionally, the analysis considers the antenna separation space loss, horizontal and vertical gain components of the antennas as well as how they are mounted on the structure. The gain components are derived from antenna pattern data published by each manufacturer.
The analysis determines how much isolation is required, if any, to prevent receiver performance degradation caused by receiver desensitization interference. The Table below depicts the results of this analysis. For each receiver, the transmitter that has the worst-case impact is displayed. The Signal Margin represents the margin in dB, before the receiver's performance is degraded. A negative number indicates that the performance is degraded and the value indicates how much additional isolation is required to prevent receiver performance degradation.

7.1 Transmitter Generated Intermodulation Analysis
Intermodulation in transmitters occurs when a signal from another transmitter is impressed on the nonlinear final output stage circuitry, usually via antenna coupling. The power level of the 1M product is determined by the power level of the incoming extraneous signal from another transmitter and by a conversion loss factor. The conversion loss factor takes into account the mixing efficiency of the transmitter's final output stage. Conversion loss differs with transmitter design, adjustment, frequency separation of the source signals, and with the order of the 1M product.
The analysis calculates all possible 1M product frequencies that could potentially interfere with receivers at the communications site based on each receiver's individual bandwidth. It then predicts each 1M signal level present at the input of each affected receiver. For each 1M frequency, the analysis considers all possible sources of 1M generation in the transmitters. For example, if there are four transmitters involve, the analysis will calculate the 1M signal level that would be generated in each transmitter. For this example, that would be four possible mixing conditions.
The analysis takes into account the transmitter's power output, modulation bandwidth, conversion losses, transmission line losses, filters, duplexers, combiners, isolators, multi-couplers and other RF devices that are present in each system. Additionally, the analysis considers the antenna separation space loss, horizontal and vertical gain components of the antennas as well as how they are mounted on the structure. The gain components are derived from antenna pattern data published by each manufacturer.
The analysis determines how much isolation is required to prevent receiver performance degradation for each 1M interference signal that occurs. Receivers experiencing transmitter generated intermodulation interference are depicted in the following Table.

8.0 Transmitter Harmonic Output Interference Analysis
Transmitter harmonic interference is due to non-linear characteristics in a transmitter. The harmonics are typically created due to frequency multiplers and the non-linear design of the final output stage of the transmitter. If the harmonic signal falls within the passband of a nearby receiver and the signal level is of sufficient amplitude, it can degrade the performance of the receiver.
The analysis takes into account the transmitter's harmonic characteristics, output level, transmission line losses, filters, duplexers, combiners, isolators, multi-couplers and other RF devices that are present in each system. Additionally, the analysis considers the antenna separation space loss, horizontal and vertical gain components of the antennas as well as how they are mounted on the structure. The gain components are derived from antenna pattern data published by each manufacturer.
The analysis determines how much isolation is required to prevent receiver performance degradation for any harmonics that fall within a receiver's· passband. Receivers experiencing transmitter harmonic interference are depicted in the following Table.

10.0 Conclusion
Based upon the data received regarding the existing radio equipment utilized by the existing commercial wireless carriers and the proposed radio configuration for the Sprint installation, there will not be any negative impact to the performance of any of the existing commercial wireless radio systems or to that of any radio system owned by the City of Frederick from the proposed Sprint installation
This analysis was performed solely based upon radio configuration data provided by AlcatelLucent and Sprint as well as queries from the FCC ULS database and EBI's internal database of existing carriers in the area. In certain instances where assumptions were required industry standard values were utilized. The scope of this study was limited to radio systems present on this tower exclusively. It does not take into account emissions from surrounding radio sources.
Additionally, this analysis was also performed assuming that all radio equipment including lines and antennas are performing to manufacturers specifications. Each system was analyzed assuming proper filtering was used to maintain compliance with all FCC licenses and reduce out of band emissions.
