Once you have installed the hardware and software, you can set up a personal area network (PAN) to connect your notebook to other Bluetooth devices via a secure radio link. Whenever your Bluetooth devices come within range of each other, communication can occur to automatically synchronize your schedule, phone book, and other databases and applications. With BlueView management software you can define and limit access of Bluetooth devices on your personal area network (PAN). Frequently-Asked Questions (FAQ) Q: What is Bluetooth? A: Bluetooth is the name for a short-range radio frequency (RF) technology that operates at 2.4 GHz and is capable of transmitting voice and data. The effective range of Bluetooth devices is 32 feet (10 meters). Bluetooth transfers data at a rate of up to 1 Mbps, which is from three to eight times the average speed of parallel and serial ports, respectively. Q: Why is the technology called Bluetooth? A: The heart of the Bluetooth brand identity is the name, which refers to the Danish king Harald “Bluetooth” Blaatand who unified Denmark and Norway. In the beginning of the Bluetooth wireless technology era, Bluetooth was aimed at unifying the telecom and computing industries. Ericsson and Nokia, founding members of the Bluetooth Special Interest Group, were influential in selecting the name. Q: How is Bluetooth used? A: Mobile professionals primarily use Bluetooth to wirelessly synchronize and transfer data among devices. Bluetooth can be thought of as a cable replacement technology. Typical uses include automatically synchronizing contact and calendar information among desktop, notebook and palmtop computers without connecting cables. Bluetooth can also be used to access a network or the Internet with a notebook computer by connecting wirelessly to a cellular phone or to a Bluetooth access point connected to a wired LAN.

A: Convenience & Organization l Eliminates cables – Offers wireless freedom to communicate with multiple devices. No need to hook up cables to several devices as the cables are replaced by radio links. l Organizes data - Automatically synchronizes data (with required application software) among devices without user intervention; ensures consistent, updated data in all devices. l Saves time - Transfers data 3 to 8 times faster than parallel and serial ports. l Adds flexibility – The Bluetooth personal area network is portable and travels with the user and the devices. Bluetooth devices can be used in the office, at home, and on the road. Low Cost of Ownership l No lost or broken cables to replace. l No need to stock numerous cables to support various mobile phone and computing device types. Global Wireless Solution l Bluetooth spectrum (2.4Ghz) is available in more than 95% of countries worldwide. Q: How secure is a Bluetooth network? A: Bluetooth employs several layers of data encryption and user authentication measures. Bluetooth devices use a combination of the Personal Identification Number (PIN) and a Bluetooth address to identify other Bluetooth devices. Data encryption (128-bit) can be used to further enhance the degree of Bluetooth security. The transmission scheme (FHSS) provides another level of security in itself. Instead of transmitting over one frequency within the 2.4 GHz band, Bluetooth radios use a fast frequency hopping spread spectrum (FHSS) technique, allowing only synchronized receivers to access the transmitted data. Q: What is Frequency-Hopping Spread Spectrum (FHSS)? A: Frequency Hopping Spread Spectrum (FHSS) is a spread spectrum modulation scheme that uses a narrowband carrier that changes frequency in a pattern known to both transmitter and receiver. Properly synchronized, they maintain a single logical channel. To an unintended receiver, FHSS appears as short-duration impu…

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 …
