The headset contains a microphone and a receiver, and is intended for hands free communications with mobile telephones containing Bluetooth compatibility or any other device that has a Bluetooth Audio Gateway. Headset power is provided by a rechargeable battery. The battery can be charged with a vehicular charge adapter or an AC charge adapter. 2 User Operated Controls The headset has the following user operated controls: - 1. Boom Switch: The power is OFF when the microphone boom is in the closed position and the power is ON when the microphone boom is in the open position. - 2. Function Button: This button is pushed for various lengths of time to initiate a call, hang up a call, pairing, transferring a call to a headset, microphone mute and call waiting. - 3. Volume Rocker Switch: The upper portion of this switch is pushed momentarily to increase the receive volume in steps and the lower portion of this switch is pushed momentarily to decrease the receive volume in steps. 3 Indicators A Blue LED at tip of microphone boom flashes at various rates and durations to indicate Power ON/OFF, Charging, Search & Pairing, BT Link Established, Standby/Sniff Mode, and Audio Link (on a call). Tones in receiver vary in duration, duty cycle and frequency to indicate Volume Steps, Volume Min, Volume Max, Low Battery, Microphone Mute, Incoming Call, and Pairing. 4 RF Scheme of Operation The channel is represented by a pseudo-random hopping sequence hopping through the 79 RF channels. The unique hopping sequence is determined by the Bluetooth device address of the master; the phase in the hopping sequence is determined by the Bluetooth clock of the master. The channel is divided into time slots where each slot corresponds to an RF hop frequency. Consecutive hops correspond to different RF hop fre-quencies. The nominal hop rate is 1600 hops/s. All Bluetooth units participating in a piconet are time- and hop-synchronized to the channel. The channel is divided into time slots, each 625 μs in length. In the time slots, master and slave can transmit packets. A TDD scheme is used where master and slave alternatively transmit. The RF hop frequency shall remain fixed for the duration of the packet. For a single packet, the RF hop frequency to be used is derived from the current Bluetooth clock value. For a multi-slot packet, the RF hop frequency to be used for the entire packet is derived from the Bluetooth clock value in the first slot of the packet.

If a packet occupies more than one time slot, the hop frequency applied shall be the hop frequency as applied in the time slot where the packet transmission was started. In total, 5 types of hopping sequences are defined: - A page hopping sequence with 32 unique wake-up frequencies distributed equally over the 79MHz, with a period length of 32. - A page response sequence covering 32 unique response frequencies that all are in an one-to- one correspondence to the current page hopping sequence. - An inquiry sequence with 32 unique wake-up frequencies distributed equally over the 79MHz, with a period length of 32. - A inquiry response sequence covering 32 unique response frequencies that all are in an one- to-one correspondence to the current inquiry hopping sequence. - A channel hopping sequence which has a very long period length, which does not show repetitive patterns over a short time interval, but which distributes the hop frequencies equally over the 79MHz during a short time interval.

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 Processing Gain FCC Testing Page 5 of 11 PG Results 23 March 2001 APPENDIX A - TEST EQUIPMENT LIST Reference:Instrument TypeName 1BlueCore Emulator BoardN/A 2Vector Signal GeneratorIFR2052 3CW Signal GeneratorIFR2025 4White Noise GeneratorHP33120A 5RF MixerM8HC-7 6RF Combiner6 dB loss combiner 7Bluetooth Motherboard and BC01B Module Casira Development Kit 85V, 4A DC Power SupplyN/A 9Spectrum AnalyserHP E4405B Page 6 of 11 PG Results 23 March 2001 APPENDIX B - TEST RESULTS Timestamp: 14:42.43, 16/11/2000 Signal Freq = 2.432 GHz Jammer Level = -85.7 dBm Jammer Offset = -500 kHz Level = -68.7 dBm BER = 0.03% PER = 0.01% SER1 = 0.01% SER2 = 0.01% Level = -70.7 dBm BER = 0.32% PER = 0.79% SER1 = 0.79% SER2 = 0.79% Level = -69.7 dBm BER = 0.11% PER = 0.18% SER1 = 0.18% SER2 = 0.18% Level = -68.7 dBm BER = 0.04% PER = 0.03% SER1 …
