Sincerely, Allan Fischer Real Estate Manager II Enclosures Sprint Nextel - NEPA RF compliance Spn nt Together with NEXTEL 6240 Sprint Parkway, Overland Park, Kansas 66251 - Office (913) 762-9233 - Fax (913) 523-0436 Date: September 23, 2005 To: City of Carlsbad 1635 Faraday Avenue Carlsbad, CA 92008 Attn: Mr. Scott Donnell From: David Kirk Site Address: 2560 Orion Way, Carlsbad, CA 92008 Site Description: rooftop Site Owner: Sprint The purpose of this letter is to demonstrate compliance with FCC standards in regard to the electromagnetic emissions from the antennas located on the parapet wall at site SD03XC155 at the following address: 2560 Orion Way, Orion Way, Carlsbad, CA 92008 The FCC, in regulating electromagnetic radiation, applies a modified version of the standards developed by the American National Standards Institute (ANSI) and the Institute of Electrical and Electronics Engineers (IEEE) to include the NCRP standard for Specific Absorption Rate or SAR, for PCS bands. These standards, when converted over to the more familiar power density specification, set a maximum power density level for public areas at 1 .OOmW/cm2 (milliwatts per square centimeter) for general population exposure and 5.00mW/cm2 for occupational exposure. For a measure of safety, this level is set 50 times lower than levels the standards committees felt could potentially be harmful for constant exposure. PCS technology uses very low power transmitters especially when compared with TV and Radio broadcasting which can be hundreds of thousands of times more powerful than a PCS station. Our antennas are designed to concentrate the majority of their signal power out of the front of the antenna in a very thin beam. Signal strength coming from the back of an antenna and from positions well below an antenna is typically hundreds of times lower than the signal in the main beam at the front of the antenna. Through software modeling techniques we can calculate the power density from a Sprint PCS installation at a variety of locations around the proposed site. The site in this instance is a parapet wall installation using a 65 degree beam width antenna. Sprint PCS evaluates all sites, to determine the percent of exposure incurred by the general public as well as occupational exposure resulting from the operation of our antennas. This is an issue we take very seriously, and much effort and manpower goes into maintaining NEPA compliant sites. In addition to this, regular audits are conducted to ensure accuracy and completeness. We have developed several proprietary software programs exclusively used to determine Power Density levels and to compute Maximum Exposure limits. It is also our policy that when a site is changed in any manner that would impact exposure levels, a new analysis is performed. All data is saved and available to the FCC upon request. The following contains information on the current FCC standards, the type of modeling Sprint PCS uses to ensure compliance to the standards, and the results of the study for this particular site. Current FCC-adopted Exposure Limits In FCC 96-326, the FCC adopted new exposure guidelines. The guidelines are given in terms of mW/cm2 and the maximum limits are termed 'Maximum Permissible Exposure' (MPE) for both occupational and general cases. Because these guidelines are based upon the same SAR limits as those in the IEEE/ANSI and NCRP guidelines, they also include the safety factors of 10 and 50 for occupational and general public scenarios respectively. The graph in Figure 1-1 shows the current FCC MPE guidelines. The two arrows indicate the cellular (-850 MHz) and PCS (-1900 MHz) frequencies. The exposure limits for PCS, expressed in terms of "power density", are 1.0 and 5.00mW/cm2 for general public and occupational cases, respectively. FCC Exposure Limits Genera Pilillc Frequency, MHz Figure 1-1: FCC Exposure Limits Current FCC Rules/Regulations The current regulations are contained in CFR Title 47, Sections 1.1307 and 1.1310. A brief summary of the current regulation is as follows: In general, all facilities, operations and transmitters regulated by the Commission must comply with the exposure limits put forth in the NEPA rules of Title 47, Part 1, Section 1.1307 and 1.1310. Applications to the Commission ... must contain a statement confirming compliance with the limits unless ... categorically excluded. Technical information showing the basis for this statement must be submitted to the Commission upon request. In the case of multiple fixed transmitters, any action necessary to bring the facility into compliance is the shared responsibility of all licensees whose transmitters contribute more than 5% of the exposure limit applicable to that transmitter. Spherical Modeling The concept of the spherical model is to assume that the EIRP of the actual antenna is being applied to a point source (true isotropic radiator). This is really only valid in the center of the main beam of the antenna but it guarantees a worst-case view everywhere else. The power density is then calculated by dividing the EIRP by the surface area of the sphere (4?r2), for the distance r away from the antenna. In general, we will consider the shortest distance between the antenna and a six (6) foot area above the roof or ground where a person might stand. Additionally, we must multiply the EIRP by a power reflection coefficient to account for the fact that reflections from the roof or ground could add constructively with the incident wave at the point in question. The equation for power density is the following: EIRP- PRO O — Where: S is power density in mw/cm2 EIRP is in watts is the power reflection coefficient (we will use 2.56 for most applications, as specified by the EPA) is the radius, direct distance from antenna (bottom) to point of interest, meters Cylindrical Modeling The concept of the cylindrical model is to take the power actually delivered to the antenna, Pt (NOT EIRP) and assume it is equally distributed over the surface of a cylinder of the same length as the antenna. If the antenna is a directional antenna then we reduce the surface area of the cylinder by BW/360 (BW is the 3-dB beam-width in degrees). This is a good near-field model. Additionally, if the antenna is mounted above the level, the average power density in a 6-foot tall area immediately above the rooftop level (or where a person might be standing or located), is reduced according to how far above/below the person is in relation to where the antenna is mounted. The equation for the power density is the following: Where: S is the power density in mw/cm2 Pt is the actual (or worst case assumed) power delivered to the antenna, watts K(Ha,La) is the correction factor for antenna mounting height Ha is the antenna mounting height, feet La is the length of the antenna, meters Rh is the horizontal distance along roof from antenna to point of interest, meters BW is the 3-dB beam-width of antenna K(Ha,La) 0.99013-0.14656*Ha 0 <= Ha < 6 0.17532-0.01076*Ha 6 <= Ha < 10 0.06772 10 <= Ha K(Ha,La) makes corrections for antennas mounted lower than the roof level and for antennas shorter than 6 feet. D Atema 0 RDtfcrOnidLad A Exposure Modeling Using Spherical and Cylindrical Modeling, it is the policy of Sprint PCS to perform sufficient analysis on each site to assure that the above mentioned FCC Rules and Regulations are being met. Sprint PCS proprietary software is used to model RF exposure conditions on rooftops and in any other areas that our antennas are used. In this situation, the antennas are mounted on the parapet wall. The following are a summary of the results obtained from our in-house modeling tools for this site; Front Transmit Power Frequency Antenna Height Length of Antenna Beam-width Exposure Limit Percent 100% 50% 33% 5% of Sprint's Antennas Cylindrical Model General 1 3.4311 6.8621 10.2932 68.6212 21.7 1900 0 4.27 65 Distance Watts MHz Feet Feet Degrees Occupational 5 mw/cm2 0.6862 Feet 1.3724 Feet 2.0586 Feet 13.7242 Feet Figure 1-2: Result for SD03XC155 (Front of Sprint's Antennas) Cylindrical Model 100 10 11 12 13 14 15 16 17 18 19 20 General —Occwpat iona1 Figure 1-3: Percent ofMPE vs. Horizontal Distance for SD03XC155 (Front ofSprint's Antennas) The results of the analysis show in Figure 1-3 that to incur 100% of the Maximum Permissible Exposure levels an individual would have to be directly within 3.4311 feet of the front of the antenna in it's main beam. This could only occur if an individual climbed in front of the antenna or placed a bucket truck less than 4 feet from the front of the antenna. Figure 1-3 shows how rapidly the power density levels fall off (in percent of FCC maximum) as the distance increases.

In other words, the person would have to be behind the antenna and closer than 0 inches. Maintenance Safeguards Routine maintenance near the antennas is no cause for concern. If for some reason the antennas need to be moved or handled then the regional RF Manager at Sprint PCS should be notified or you may call at 1-888-859-1400 to facilitate a power down. Summary As can be seen from the data, these antennas are mounted on the parapet wall above ground level. An individual would have to come within less than 4 feet of the front of Sprint's antennas (worst case) or within 0 inches of the back of Sprint's antennas to reach anywhere close to FCC maximum exposure limits. Since these antennas are mounted above ground level, with limited access, this is unlikely to occur. Exposure to Radio Frequency Electromagnetic Fields is of great concern to Sprint PCS and we evaluate all sites for compliance to current FCC rules and regulations. We are continually striving to improve the quality of our modeling techniques through continuous improvement of our software tools and training procedures. We recognize our role as an industry leader to place the health and welfare of the public and occupational workers in high regard and we will continue to do so through mandatory modeling and measurements as required. We determine the hazard that is present and inform occupational workers through training and appropriate signage. Please don't hesitate to call if you should have any questions or are in need of any further information regarding the RF emissions from this site.
