FCC ID: BQI01DR-10000 SECTION 7 RF EXPOSURE INFO FCC ID: BQI01DR-10000 7.0 RF Safety Requirements to 2.1091/95.1125 for Mobile Transmitters Part 95 transmitters are considered categorically excluded from routine environmental evaluation as given in 47 CFR 2.1091. However, the following information is presented to prove compliance with the limits. Power Output The EUT’s maximum output power as measured directly from the transmitter module is +12.0 dBm (15.8 mW). The EUT may utilize 2 different types of antenna’s (patch @ + 2 dBi, monopole @ 0 dBi). Frequency of Fundamental (MHz) Measurement (Watt)* Antenna Gain (dBi) P ERP (Watt) 608.6656- 612.898133 0.01582.00.0251 Source Based Time Averaging Source Time Averaging has not been evaluated regarding this product. MPE Calculations The limits for this unit (uncontrolled exposure) are 0.4 mW/cm 2 . Taking the RF Density Field Equation: S = (EIRP in mW)/(4πR 2 ) and solving for Distance R R = SQRT (EIRP in mW)/(S4π) Solving the above equation yields R (cm) = SQRT (25.1(mw))/(0.4(mW/cm 2 )*4*π) = 5.0 cm Since the EUT is designed only for mobile applications (where the expected separation distance between antenna and humans is greater than 20 cm), all manual instructions have specified 20 cm as the minimum exposure distance.

The DR-10000 is a wireless Access Point (AP) designed for use in medical monitoring applications. The DR- 10000 receives patient monitoring data from similar radios (FCC ID: BQI00DT-4500) attached to the patients in that hospital. The DR-10000 is linked to other DR-10000's through a 10Base-T Ethernet backbone. This backbone allows the AP's to pass patient data back to the end user of the system - a nurses monitoring station. The DR-10000 is composed of two 608-614 MHz wireless transceivers and Ethernet conversion circuitry that passes data from these transceivers to the Ethernet backbone. The DR-10000 may operate with two different types of antennas: a 0 dBi monopole to provide omni-directional coverage and a +2 dBi patch antenna to provide unidirectional coverage. The unit requires external DC power but has its own internal voltage regulation. The DR-10000 is self contained in a plastic package and is designed to be installed on the ceiling of a hospital hallway. The EUT has been previously approved under FCC ID: BQI00DR-10000 by the FCC on 9/8/00 (original certification) and 12/28/00 (permissive change). For the permissive change application, the transmitter modules were modified as follows: 1) The SAW RF bandpass filter (reference designator F5 in the transmit chain has been replaced by a third order, top capacitively coupled LC filter. This change will result in increased yield. 2) The power amplifier transistor, HBFP450 (reference designator Q3) in the transmit chain has been replaced by transistor BFP450. The replacement transistor is the functional and performance equivalent of the original transistor. The change is in place to allow alternate supply to facilitate planning. Since only a portion of the tests needed to be performed for the permissive change application, this application includes data from the both the original submittal and the permissive change application. FCC ID: BQI01DR-10000 Related Submittal(s)/Grant(s) The EUT has been previously approved under FCC ID: BQI00DR-10000 on September 8, 2000 under Part 15.242 and with a permissive change on December 28, 2000. The EUT is being resubmitted under FCC ID: BQI01DR-10000 to new requirements specified in Part 95 of the rules. Additionally, the EUT will be used with other transceivers (already submitted and approved under FCC ID: BQIOODT-4500). FCC ID: BQI01DR-10000 SECTION 2 TESTS AND MEASUREMENTS FCC ID: BQI01DR-10000 TESTS AND MEASUREMENTS Configuration of Tested System The sample was tested per ANSI C63.4, Methods of Measurement from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (1992). Conducted and radiated emissions data were taken with the test receiver or spectrum analyzer's resolution bandwidth adjusted to 9 kHz and 120 kHz, respectively. All measurements are peak unless stated otherwise. The video filter associated with the spectrum analyzer was off throughout the evaluation process. Interconnecting cables were manipulated as necessary to maximize emissions. A block diagram of the tested system is shown in Figure 1. Test configuration photographs for spurious and fundamental emissions are shown in Figure 2. Test Facility Testing was performed at US Tech's measurement facility at 3505 Francis Circle, Alpharetta, GA. This site has been fully described and submitted to the FCC, and accepted in their letter marked 31040/SIT. Additionally this site has also been fully described and submitted to Industry Canada (IC), and has been approved under file number IC2982. Modifications No modifications were made by US Tech, to bring the EUT into compliance with FCC Part 95 limits for the transmitter portion of the EUT or the Class A Digital Device Requirements. Test Equipment Table 2 describes test equipment used to evaluate this product. FCC ID: BQI01DR-10000 FIGURE 1 TEST CONFIGURATION Transceiver (EUT) Monitor Computer Keyboard Mouse AC Adapter Patc…

FCC ID: BQI01DR-10000 Field Strength Of Spurious Emissions (47 CFR 95.1115(b)) Measurements were made using a peak detector. Field strength of Spurious Emissions are shown in Tables 4a through 4b and Figures 3a through 3b. For comparison to the average limits, duty cycle corrections were made as shown below. Both Radios were checked (one radio with patch antennas and the other with monopoles). The results from each radio were similar, but preliminary data showed that the Radio with the monopole antennas to be worse case. Therefore all results shown are for the radio configured with the monopole antennas (for a low and high channel). Duty Cycle Correction During 100 msec: The system is designed that the system hops at 35 msec per channel. The system will only be on one channel in any 100 msec period of time. During this 35 msec per channel, each transmitter is allotted only a small duration of this period (5 msec max). Therefore the worse case duty cycle is: Duty Cycle Correction = 20 log (0.05) = -26.0 dB FCC ID: BQI01DR-10000 TABLE 4a FIELD STRENGTH OF SPURIOUS EMISSIONS Test Date:October 3, 2000 UST Project:01-0406 Customer:VitalCom, Inc.
