(dba EBI Consulting) has been contracted by Sprint Nextel to conduct radio frequency electromagnetic (RF-EME) modeling for Sprint Site FSO4XC075 located at 1070 Broadway in Burlingame, California to determine RF-EME exposure levels from existing and proposed Sprint wireless communications equipment at this site. As described in greater detail in Section I I.0 of this report, the Federal Communications Commission (FCC) has developed Maximum Permissible Exposure (MPE) Limits for general public exposures and occupational exposures. This report summarizes the results of RF-EME modeling in relation to relevant FCC RF-EME compliance standards for limiting human exposure to RF-EME fields. This report contains a detailed summary of the RF EME analysis for the site. This document addresses the compliance of Sprint's proposed transmitting facilities independently and in relation to all collocated facilities at the site. ��T 21 B Street • Burlington, MA 01803 • 1.800.786.2346 1 , RF-EME Compliance Report Site No. FSO4XC075 EBI Project No. 62121882 1070 Broadway, Burlingame, California I.O LOCATION OF ALL EXISTING ANTENNAS AND FACILITIES AND EXISTING RF LEVELS This project involves the removal of three (3) existing antennas replaced with three (3) proposed Sprint wireless telecommunication antennas on a rooftop located at 1070 Broadway in Burlingame, California. There are three Sectors (A, B, and C) proposed to be replaced at the site, with one ( I) antenna that may be re-installed per sector. Based on drawings and aerial photography review, AT&T also has wireless antennas on the rooftop. These antennas were included in the modeling analysis. 2.0 LOCATION OR ALL APPROVED (BUT NOT INSTALLED) ANTENNAS AND FACILITIES AND EXPECTED RF LEVELS FROM THE APPROVED FACILITIES There are no antennas or facilities that are approved and not installed based on information provided to EBI and Sprint at the time of this report. 3.0 NUMBER AND TYPES OF WTS WITHIN I00 FEET OF THE PROPOSED SITE AND ESTIMATES OF CUMULATIVE EMR EMISSIONS AT THE PROPOSED SITE With the exception of the antennas mentioned in Section I.O, there are no other Wireless Telecommunication Service (WTS) sites observed within 100 feet of the proposed site. 4.0 LOCATION AND NUMBER OF THE SPRINT ANTENNAS AND BACK-UP FACILITIES PER BUILDING AND NUMBER AND LOCATION OF OTHER TELECOMMUNICATION FACILITIES ON THE PROPERTY Sprint proposes the removal of three (3)existing antennas replaced with three (3)proposed Sprint wireless telecommunication antennas on a rooftop located at 1070 Broadway in Burlingame, California. There are three Sectors (A, B, and C) proposed to be replaced at the site, with two (2) antennas that may be re-installed per sector. In each settor, there is proposed to be one antenna transmitting in the 800 MHz and the 1900 MHz frequency ranges. The Sector A antennas will be oriented 285° from true north. The Sector B antennas will be oriented 100° from true north. The Sector C antennas will be oriented 205° from true north. The bottoms of the antennas in all three sectors are 0 feet above the nearest walking service. Based on drawings and aerial photography review, AT&T also has wireless antennas on the rooftop. These antennas were included in the modeling analysis. 5.0 POWER RATING FOR ALL EXISTING AND PROPOSED BACKUP EQUIPMENT SUBJECT TO THE APPLICATION The operating power for modeling purposes was assumed to be 20 Watts per transmitter for the 800 MHz antenna and there will be one (I) transmitter operating at this frequency. Additionally, for modeling purposes it was assumed to be 20 Watts per transmitter and seven (� transmitters operating at the 1900 MHz. 6.0 TOTAL NUMBER OF WATTS PER INSTALLATION AND THE TOTAL NUMBER OF WATTS FOR ALL INSTALLATIONS ON THE BUILDING The effective radiated power (ERP) for the 800 MHz transmitter combined on site is 645 Watts. The ERP for the 1600 MHz transmitters combined on site is 1,449 Watts. The ERP for the 1900 MHz transmitters combined on site is 8,402 Watts. The ERPs for other carriers on site was not provided. ::�IEBI 21 B Street • Burlington, MA 01803 • 1.800.786.2346 RF-EME Compliance Report EBI Project No. 62121882 Site No. FSO4XC075 1070 Broadway, Burlingame, California 7.0 PREFERRED METHOD OF ATTACHMENT OF PROPOSED ANTENNA WITH PLOT OR ROOF PLAN INCLUDING: DIRECTIONALITY OF ANTENNAS, HEIGHT OF ANTENNAS ABOVE NEAREST WALKING SURFACE, DISCUSS NEARBY INHABITED BUILDINGS Based on the information provided to EBI, the information indicates that the proposed antennas are to be mounted atop the rooftop penthouse, operating in the directions, frequencies, and heights mentioned in section 4.0 above. The site building is surrounded by other commercial buildings and parking lots. 8.0 ESTIMATED AMBIENT RADIO FREQUENCY FIELDS FOR THE PROPOSED SITE Based on worst-case predictive modeling, the worst-case emitted power density may exceed the FCC's general public limit within approximately 16 feet of Sprint proposed antennas at the penthouse and penthouse roof levels. Modeling also indicates that the worst-case emitted power density may exceed the FCC's occupational limit within approximately 6 feet of Sprint proposed antennas at the penthouse and penthouse roof levels. At the nearest walking/working surfaces to the proposed Sprint antennas, the maximum power density is 2,505.30 percent of the FCC's general public limit (501.06 percent of the FCC's occupational limit). The composite exposure level from all other carriers existing on this site combined with Sprint's proposed antennas is 2,493.60 percent of the FCC's general public limit (498.72 percent of the FCC's occupational limit) at the nearest walking/working surFace to each antenna. Based on worst-case predictive modeling, there are no areas at ground level related to the proposed Sprint antennas that exceed the FCC's occupational or general public exposure limits at this site. At ground level, the maximum power density generated by the Sprint antennas combined with the existing other carriers antennas on site is 2.70 percent of the FCC's general public limit (0.54 percent of the FCC's occupational limit). The inpuu used in the modeling are summarized in the RoofViewOO export file presented in Appendix B. There are no modeled areas on the rooftop or ground that exceed the FCC's limits for general public or occupational exposure in front of the other carrier antennas. 9.0 SIGNAGE AT THE FACILITY IDENTIFYING ALL WTS EQUIPMENT AND SAFETY PRECAUTIONS FOR PEOPLE NEARING THE EQUIPMENT AS MAY BE REQUIRED BY THE APPLICABLE FCC ADOPTED STANDARDS (DISCUSS SIGNAGE FOR THOSE WHO SPEAK LANGUAGES OTHER THAN ENGLISH) Signs are the primary means for control of access to areas where RF exposure levels may potentially exceed the MPE. It is recommended that additional signage be installed for the new antennas making people aware of the antennas locations. There are fields in front of the proposed antennas and therefore barriers are recommended. Additionally, there are areas where workers elevated above the rooftop may be exposed to power densities greater than the general population and occupational limits. Workers and the general public should be informed about the presence and locations of antennas and their associated fields. Additionally, access to this site is accomplished via a roof access door located on the main roof. Access to the facility is monitored and as such, but it should be assumed that the general public is still able to access the rooftop. I 0.0 STATEMENT ON WHO PRODUCED THIS REPORT AND QUALIFICATIONS Please see the certifications attached in Appendix A below. ��T 21 B Street • Burlington, MA 01803 • 1.800.786.2346 1 RF-EME Compliance Report Site No. FSO4XC075 EBI Project No. 62121882 1070 Broadway, Burlingame, California I I.O FEDERAL COMMUNICATIONS COMMISSION (FCC) REQUIREMENTS The FCC has established Maximum Permissible Exposure (MPE) limits for human exposure to Radiofrequency Electromagnetic (RF-EME) energy fields, based on exposure limits recommended by the National Council on Radiation Protection and Measurements (NCRP) and, over a wide range of frequencies, the exposure limits developed by the Institute of Electrical and Electronics Engineers, Inc. (IEEE) and adopted by the American National Standards Institute (ANSI) to replace the 1982 ANSI guidelines. Limits for localized absorption are based on recommendations of both ANSI/IEEE and NCRP. The FCC guidelines incorporate two separate tiers of exposure limits that are based upon occupational/controlled exposure limits (for workers) and general public/uncontrolled exposure limits for members of the general public. Occupational/controlled exposure limits apply to situations in which persons are exposed as a consequence of their employment and in which those persons who are exposed have been made fully aware of the potential for exposure and can exercise control over their exposure. Occupational/ controlled exposure limits also apply where exposure is of a transient nature as a result of incidental passage through a location where exposure levels may be above general public/uncontrolled limits (see below), as long as the exposed person has been made fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. General pu6lic/uncontrolled exposure limits apply to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Therefore, members of the general public would always be considered under this category when exposure is not employment-related, for example, in the case of a telecommunications tower that exposes persons in a nearby residential area. Table I and Figure I(below), which are included within the FCC's OET Bulletin 65, summarize the MPE limits for RF emissions. These limits are designed to provide a substantial margin of safety. They vary by frequency to take into account the different types of equipment that may be in operation at a particular facility and are "time-averaged" limits to reflect difFerent durations resulting from controlled and uncontrolled exposures. The FCC's MPEs are measured in terms of power (mV1� over a unit surface area (cmz). Known as the power density, the FCC has established an occupational MPE of 5 milliwatts per square centimeter (mW/cm2) and an uncontrolled MPE of I mW/cm2 for equipment operating in the and 1900 MHz frequency range. For the Sprint equipment operating at 800 MHz, the FCC's occupational MPE is 2.66 mW/cm2 and an uncontrolled MPE of 0.53 mW/cm2. These limits are considered protective of these populations. ��T 21 B Street • Burlington, MA 01803 • 1.800.786.2346 1 RF-EME Compliance Report Site No. FSO4XC075 EBI Project No. 62121882 1070 Broadway, Burlingame, California Table I: Limits for Maximum Permissible Exposure (MPE) (A) Limits for Occupational/Controlled Exposure Frequency Range Electric Field Magnetic Field Averaging Time (MHz) Strength (E) Strength (H) Power Density (S) �E]Z, [H]2, or S (Vlm) �q�m� (mW/cm ) (minutes) 300-1,500 -- -- f/300 6 I,500- I 00,000 -- -- 5 6 (B) Limits for General Public/Uncontrolled Exposure Frequency Range Electric Field Magnetic Field Averaging Time (MHz) Strength (E) Strength (H) Power Density (S) �E�z� �H]�, or S (V/m) (A/m) �mW��m � (minutes) 0.3- I.34 614 I.63 ( I 00)* 30 I.34-30 824/f 2.

RF-EME Compliance Report Site No. FSO4XC075 EBI Project No. 62121882 1070 Broadway, Burlingame, California Personal Communication (PCS) facilities used by Sprint in this area operate within a frequency range of 800-1900 MHz. Facilities typically consist of: I) electronic transceivers (the radios or cabinets) connected to wired telephone lines; and 2) antennas that send the wireless signals created by the transceivers to be received by individual subscriber units (PCS telephones). Transceivers are typically connected to antennas by coaxial cables. Because of the short wavelength of PCS services, the antennas require line-of-site paths for good propagation, and are typically installed above ground level. Antennas are constructed to concentrate energy towards the horizon, with as little energy as possible scattered towards the ground or the sky. This design, combined with the low power of PCS facilities, generally results in no possibility for exposure to approach Maximum Permissible Exposure (MPE) levels, with the exception of areas directly in front of the antennas. Statement of Compliance A site is considered out of compliance with FCC regulations if there are areas that exceed the FCC exposure limits and there are no RF hazard mitigation measures in place. Any carrier which has an installation that contributes more than 5% of the applicable MPE must participate in mitigating these RF hazards. 12.0 LIMITATIONS This report was prepared for the use of Sprint Nextel. It was performed in accordance with generally accepted practices of other consultants undertaking similar studies at the same time and in the same locale under like circumstances. The conclusions provided by EBI are based solely on the information provided by the client. The observations in this report are valid on the date of the investigation. Any additional information that becomes available concerning the site should be provided to EB) so that our conclusions may be revised and modified, if necessary. This report has been prepared in accordance with Standard Conditions for Engagement and authorized proposal, both of which are integral parts of this report. No other warranty, expressed or implied, is made I 3.0 SUMMARY AND CONCLUSIONS EBI has prepared this Radiofrequency Emissions Compliance Report for the proposed Sprint telecommunications equipment at the site located at I 070 Broadway in Burlingame, California. EBI has conducted theoretical modeling to estimate the worst-case power density from Sprint antennas and the other carriers' existing antennas to document potential MPE levels at this location and ensure that site control measures are adequate to meet FCC and OSHA requirements. As presented in the preceding sections, based on worst-case predictive modeling, the worst-case emitted power density may exceed the FCC's general public limit within approximately 16 feet of Sprint proposed antennas at the penthouse and penthouse roof levels. Modeling also indicates that the worst-case emitted power density may exceed the FCC's occupational limit within approximately 6 feet of Sprint proposed antennas at the penthouse and penthouse roof levels. Signage is recommended at the site as presented in Section 9.0. Posting of the signage and installation of the recommended barriers brings the site into compliance with FCC rules and regulations. �ESI 21 B Street • Burlington, MA 01803 • 1.800.7862346 RF-EME Compliance Report EBI Project No. 62121882 Appendix A Certifications Site No. FSO4XC075 1070 Broadway, Burlingame, California �iIEBI 21 B Street • Burlington, MA 01803 • I.800.786.2346 RF-EME Compliance Report EBI Project No. 62121882 Preparer Certification I, Kyle Saunders, state that: Site No. FSO4XC075 1070 Broadway, Burlingame, California ■ I am an employee of EnviroBusiness Inc.
