P-801T SAR Analysis Dave Gribble June 27, 2000 Summar y This document will present an electromagnetic environmental evaluation for the P-801T portable radio. Emphasis will be placed on deriving a maximum likely exposure level. This analysis will show that, based on projected worst-case parameters, the P-801T does not present an excessive RF exposure risk and comfortably meets the FCC Human Exposure limits. References: • CFR 47, 2.1093 “Radiofrequency radiation exposure evaluation: portable devices.” • FCC OET Bulletin 65, Supplement C “Additional Information for Evaluating Compliance of Mobile and Portable Devices with FCC Limits for Human Exposure to Radiofrequency Emissions” Exposure Limits: Portable devices are subject to a routine environmental evaluation for RF exposure prior to equipment authorization or use. The P-801T radio will be sold exclusively to public safety / public service customers, and never to the general public. Therefore, the P-801T will be evaluated against the “Occupational / Controlled” exposure limits (reproduced below, emphasis added). CFR 47, 2.1093 (d) (1) Limits for Occupational/Controlled exposure: 0.4 W/kg as averaged over the whole-body and spatial peak SAR not exceeding 8 W/kg as averaged over any 1 gram of tissue (defined as a tissue volume in the shape of a cube). Exceptions are the hands, wrists, feet and ankles where the spatial peak SAR shall not exceed 20 W/kg, as averaged over any 10 grams of tissue (defined as a tissue volume in the shape of a cube). Occupational/Controlled limits apply when persons are exposed as a consequence of their employment provided these persons are fully aware of and exercise control over their exposure. Awareness of exposure can be accomplished by use of warning labels or by specific training or education through appropriate means, such as an RF safety program in a work environment. The P-801T user’s manual (and training materials) will include discussion of electromagnetic exposure. Users will be warned to keep their transmit time limited and to hold the antenna at least 2 inches away from them at all times, in all configurations. Analytical Parameters The P-801T transmitter is designed for 3 Watts maximum power, in the 806-824 MHz frequency band. It is shipped with a 0dBi antenna. The user is cautioned not to hold the antenna closer than two (2) inches. The P-801T operates in two modes: analog and digital. In the analog mode, the radio limits transmission times to 30 seconds, but the transmitter is on 100% of the transmit time. In the digital mode, the radio also limits transmission time to 30 seconds, and the waveform used is a 2-slot time-division-multiple-access (TDMA), so the transmitter is on only 50% of the transmit time. Since the analog mode produces more exposure, the analog mode will be used for this analysis. In both modes, the P-801T is designed to be used in an industry-standard “90-5-5” usage model. Under this model, the radio is monitoring the channel 90% of the time, receiving (with active audio) 5% of the time, and transmitting for the final 5% of the time. For this analysis we will consider that a user might operate with a maximum 20% duty factor. This will represent a worst-case level of exposure. The FCC rules (reproduced below) allow us to make this assumption. CFR 47, 2.1093 (d): (4) For purposes of analyzing portable transmitting devices under the occupational/controlled criteria, the time-averaging provisions of the MPE guidelines identified in §1.1310 of this chapter can be used in conjunction with typical maximum duty factors to determine maximum likely exposure levels. Rather than use extensive computational modeling, this analysis will presume that the human body is not at all reflective to electromagnetic energy. In other words, this analysis will assume that the portion of the body under RF exposure will absorb all of the incident energy, and reflect none. Also, for this analysis, the human body will be considered to have only three densities. The densities used are taken from OET Bulletin 65, Supplement C. We will use 1035 kg/m 3 (=1.035 g/c m 3 ) for flesh (brain / muscle) and we will use 1850 kg/m3 (=1.85 g/cm 3 ) for bone (skull). Anal ysis Consider the case of the user operating the transmitter with the antenna two (2) inches from his head. The transmitter maximum output power is radiated from the antenna in a spherical pattern (because the antenna has 0dBi gain). Consider a series of concentric spheres centered at the antenna. The first sphere which touches the users head will have the highest power density. The surface area of this sphere is: 2 4 rAsphere π= Since the antenna is isotropic, we can assume that the power is spread evenly over the surface of this sphere. This means that: 2 4 r P tyPowerDensi π = At a radius of 2 inches (r=5.1cm), the power density on the surface of the sphere is 9.2 mW/cm 2 . Now consider the flesh that the sphere is touching. The peak exposure limit is written in terms of W/kg, averaged over any 1 gram of tissue in the shape of a cube. To relate tissue mass (grams) to power absorption, we need to determine how much of the sphere is subtended by the tissue in question. Since we are assuming the tissue is in the head, it seems appropriate to use skull tissue (density=1.85 g/cm 3 ). 1 gram of skull tissue would then correspond to a 0.54 cm 3 sized cube. This cube of skull tissue would measure 0.81 cm on each side, and would cover approximately 0.66cm 2 of the radiation sphere’s surface area. Surprisingly, due to its lower density, it is more appropriate to assume that the users head is made of flesh (muscle or brain) rather than skull. The lower flesh density (=1.035 g/cm 3 ) leads to a 1 gram flesh cube measuring 0.99 cm on each side. This cube covers approximately 0.98cm 2 of the radiation sphere’s surface area. Since the tissue cube covers 0.98cm 2 of the radiation sphere, and since the sphere’s power density is 9.2mW/cm 2 , we can see that the tissue…

SAR COMPLIANCE TESTING OF M/A-COM MODEL P-801T PORTABLE PUSH-TO-TALK RADIO FINAL TECHNICAL REPORT October 24, 2000 Submitted to:Mr. A. E. (Andy) Moysenko Manager, Technology Programs M/A-Com, Inc. 1011 Pawtucket Blvd. Lowell, MA 01853-3295 Submitted by:Om P. Gandhi Professor of Electrical Engineering University of Utah 50 S Central Campus Dr., Rm. 3280 Salt Lake City, UT 84112-9206 i SAR COMPLIANCE TESTING OF M/A-COM MODEL P-801T PORTABLE PUSH-TO-TALK RADIO Summary A widely-accepted finite-difference time-domain (FDTD) computational technique has been used for a heterogeneous, anatomically-based model of the human to determine maximum peak 1-g specific absorption rates (SAR) for four typical configurations of M/A-Com Model P- 801T Portable Push-to-Talk Radio for two midband frequencies of the transmission bands. The FDTD-calculated gains of the two antennas of -0.1 and -3.2 dBi compare extremely well with gains of 0 and -3.0 dBi measured for these antennas. The maximum 1-g SARs for the four considered configurations of the radio for the analog (100% duty cycle mode) vary from 1.53 to 7.02 W/kg with the highest SAR when the "microphone" is mounted on the lapel at the shoulder. The SAR values are less than the FCC occupational limit of 8.0 W/kg for any 1-g of tissue. For a vast majority of situations, the radio will be used in the TDMA mode with 50% duty cycle. Under these conditions, the maximum 1-g SARs would be one-half of the above values and would vary from 0.77 to 3.51 W/kg for the four configurations, respectively. 1 SAR COMPLIANCE TESTING OF M/A-COM MODEL P-801T PORTABLE PUSH-TO-TALK RADIO I. Introduction The U.S. Federal Communications Commission (FCC) has adopted limits of human exposure to RF emissions from mobile and portable devices that are regulated by the FCC [1]. The FCC has also issued Supplement C (Edition 97-01) to OET Bulletin 65 defining both the measurement and the computational procedures that should be followed for evaluating compliance of mobile and portable devices with FCC limits for human exposure to radiofrequency emissions [2]. The partial-body SAR limits prescribed by the FCC are 8.0 W/kg for occupational/controlled exposures and 1.6 W/kg for general population/uncontrolled exposures. The maximum partial-body SAR is to be obtained by averaging over any 1 g of tissue defined as a tissue volume in the shape of a cube [1, 2]. The M/A-Com Model P-801T Two-Way Portable Radio FCC ID#BV8P-801T can radiate up to a maximum power of 3 W over the frequency bands 806-824 MHz and 851-870 MHz. According to the manufacturer, the equipment is to be sold exclusively to public safety/public service agencies and not to the general public. Training will be required on use of this equipment prior to issue to users. SAR compliance testing is thus required for the peak 1-g SAR of 8.0 W/kg for occupational/controlled exposures [1, 2]. According to FCC 96-326 [1], "use of appropriate numerical and computational techniques, such as FDTD analysis, is acceptable for demonstrating compliance with the SAR values. Studies by O. P. Gandhi and others indicate that such techniques offer valid means to determine energy absorption characteristics in exposed subjects." For SAR compliance testing of the M/A-Com Model P-801T Portable Radio, we have used the widely accepted FDTD method for the anatomically-based model of the human body [3, 4]. Some reasons for selecting the numerical method, rather than the experimental phantom model, are as follows: 1. The experimental phantom models of the face or the human waist, two of the locations where the two-way radio is held in operation are not readily available. 2 2. Anatomically-based models have the advantage of modeling the curved shapes as well as the heterogeneities of the tissues. 3. Flat phantom models may be used. But, as given in Table 4, these models tend to grossly overestimate the SARs because of lack of curvature such as for the face and the body. Using the numerical method results in putting some of the tissues at realistic distances which are generally greater than those for a flat phantom model (see Figs. 3, 6, 9, 10 for visualization of the Radio P-801T vis à vis the human model). 4. Some individuals have alluded to leakage electromagnetic fields from the electronic components in the handset. There is, however, no proof for this allegation. In fact, as given in [5], the experimentally-determined SARs for 10 experimental wireless handsets five each at 835 and 1900 MHz were within ± 20 percent (± 1 dB) of those determined from the FDTD computational method. This slight difference of ± 1 dB may well be due to the fact that the numerical method uses a 15 tissue heterogeneous anatomic model of the head and neck while the experimental phantom uses a relatively thin shell with a homogeneous liquid in it. 5. Lastly, the manufacturer uses a well-shielded chassis of the handset thus minimizing any leakage radiation from the internal electronic components. This is described in detail in Section II. II. The M/A-Com Model P-801T Portable Push-to-Talk Radio A photograph of the M/A-Com Model P-801T Radio is given in Fig. 1. As aforementioned, the radio transmits in the frequency band 806-824 MHz and 851-870 MHz with a maximum ERP of three watts or 34.8 dBm. The approximate dimensions of the radio are as follows: width 2.3", depth 1.5" and height 6.1". As seen in Fig. 1, a sleeve type, nominal half wave dipole antenna is mounted in the back right-hand corner at the top of the die cast aluminum chassis in rugged polycarbonate housing of the handset. The sleeve type antenna has the following dimensions: 3 Diameter of unshielded wire (for the upper part of the antenna) = 1.7 mm Diameter of the rubber sheathing around the antenna = 0.22" (5.6 mm) Unshielded length of the antenna = 159 mm Length of the metallic shielding sleeve (at the base of the antenna) = 16 mm Diameter of the shielding sleeve = 0.75" (19.05 mm) Thickness of the rubber sheathing around …
