ILAC MRA 0528 Lab Code: 200102-0 FCC ID: NKRBT500 ADT No.: 910222R03 RF Exposure Measurement (Mobile Device) 1. Introduction 2.4 GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC), and the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. 2. Classification The antenna of the product, under normal use condition, is at least 20 cm away from the body of the user. Warning statement for keeping 20 cm separation distance and the prohibition of operating next to a person has been printed on the users manual. So, this product is classified as the Mobile Device. 3. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b).

If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 5.

Page 1 of 11 PG Results 23 March 2001 Filename: BlueCore01_BC01b_PG_Results_v2.1 MEMORANDUM Distribution:Peter Flittner, Robert Young, James Collier cc: Prepared By:Alex Busteed Subject:Results of Processing Gain Tests for FCC Qualification 1 INTRODUCTION This memo presents the results of the Processing Gain (PG) tests carried out for FCC qualification of the Cambridge Silicon Radio BC01B Bluetooth chip. The FCC states that the PG from a hybrid Bluetooth receiver must be greater than 17 dB when measured in accordance with the Continuous Wave (CW) jamming margin method. Testing of the BC01b has found the PG due to the DS section to be approximately 5 dB and the PG due to the FH part to be approximately 15 dB. It is therefore concluded that the BC01B complies with the FCC PG requirements for radio communication systems. The rest of this paper outlines the PG measurement technique and discusses the test results. Appendix A contains a list of test equipment and Appendix B contains a printout of the measurement results. 2 METHOD 2.1 PG Definition The Processing Gain from a frequency hopping communication system is derived from two parts, the FH section and the DS section. The PG due to FH is given by a simple equation and is constant. However measurement of the PG due to DS is a little more complex. One technique is to use the CW jamming margin method. This method measures PG due to DS using the following algorithm: A CW signal generator is stepped in 50kHz increments across the passband of the system, recording at each point the generator level required to produce the 0.1% Packet Error Rate (PER). This is the jammer level. This level is then referenced to the output power of the intended Bluetooth signal and the Jammer to Signal Ratio JSR is thus calculated. The worst 4 Page 2 of 11 PG Results 23 March 2001 JSR measurements are discarded and the worst remaining JSR is used to calculate the PG due to DS as follows: sysp LJSRSNRG++= min where G p = the processing gain of the system, SNR = the signal to noise ratio required for 0.1% BER, JSR min = minimum J/S ratio and L sys = system losses. 2.2 PG Measurement Technique Figure 1 provides an overview of the PG measurement technique. The measurement is performed in two parts, measurement of the system SNR and measurement of JSR min . Figure 1: PG Measurement Technique The system SNR is calculated using the following algorithm. Generate Bluetooth PRBS-9 packets using a BC01B emulator (1) and a Vector Signal Generator (2). Combine this signal with white noise of a constant level, which is generated using a noise source (4) and a CW Signal Generator (3). Then vary the level of the Bluetooth signal until the BER measured by the BC01B (7) is 0.1%. The resulting SNR is the signal level divided by the Noise level. Page 3 of 11 PG Results 23 March 2001 The JSR for a given jamming frequency is calculated using the following algorithm. Generate Bluetooth PRBS-9 packets using the BC01B emulator (1) and the Vector Signal Generator (2). Combine this signal with a constant CW tone at the jamming frequency using a CW Signal Generator (5) and a combiner (6). Then vary the level of the Bluetooth signal until the PER measured by the Casira Bluetooth Module (7) is 0.1%. The resulting JSR is the signal level divided by the jamming level. 3 RESULTS 3.1 Overview The measurements found that the PG due to DS caused by the access code in page and inquiry mode is found to be approximately 5dB when the access code is a relatively random mixture of 1's and 0's. A random access code causes the most Inter Symbol Interference (ISI) and hence the worst PG for a hybrid system. Therefore only the results for this access code are used in the PG calculation. The PG due to FH is given as PG FH = 10 log 10 (number of frequency hops) The number of hops in a Bluetooth system is 32, therefore the PG due to FH is approximately 15 dB. When this is added to the PG due to DS, the total PG for the BC01B is approximately 20 dB, above the minimum PG requirement for FCC qualification. 3.2 Detailed Results Test Date:17/11/00 Sample Time: 30 seconds Access Code: c6967e Signal Frequency:2.432GHz Receiver Sensitivity: -88.7 dBm Jammer Signal Level:-85.7 dBm Measured SNR: 18.8dB System Losses: 2dB To calculate processing gain, ignore the worst 20% of data points and then apply the following formula: Page 4 of 11 PG Results 23 March 2001 sysp LJSRSNRG++= min Where G p = Processing Gain of the module SNR = signal to noise ratio of the module JS min = minimum J/S ratio after the worst 20% of J/S samples have been discarded L sys = System losses A total of 20 samples were taken by stepping the jamming signal frequency offsets in 50kHz increments over the bandwidth of the receiver. The worst 4 samples were found at –500kHz, -450kHz, -400kHz and 500kHz and were discarded. The remaining minimum J/S ratio was found to be -15.4dB at an offset of +350kHz Thus, the processing gain due to direct sequence spreading in page and inquiry mode is dBG p 4.524.158.18=+−= -500-400-300-200-1000100200300400500 -30 -25 -20 -15 -10 -5 0 5 Jamming Frequency Offset (kHz) J/S (dBs) J/S ratio performance for Proce…
