North America By attaching themark to this product, we confirm: This equipment complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesirable operation. IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the following antenna installation and device operating configurations must be satisfied: The device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter. Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment. This device has been designed to operate with an antenna that has a maximum gain of 0 dB. Antennae that have a higher gain are strictly prohibited as per regulations of Industry Canada. The required antenna impedance is 50 ohms. 44 44 To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that required for successful communication.

Cover Letter(s)

Response to TCB findings FCC ID: PEYBLADE2 Hi Mark, We have reviewed the application and have identified the following issues: 1. The processing gain (PG) data is for a different device than that for which certification is sought. The FCC has stated that processing gain data is dependent on layout and component selection. Data from the chip set alone is not enough to prove compliance. If generic data from a different device using the same chipset is to be accepted, a letter must be provided which states that the layout and all component values in the RF path are identical in the device for which data is presented. Please submit PG data for the device or submit a letter which documents that the device is identical to the device measured for processing gain. We did note the comments in your email. Response: The applicant provided the email below: Barry, attached is the response from Joe Dichoso to Chris Neal (Cambridge Silicon Radio) regarding the processing gain of the BC01 radio modem/ baseband chip. This email is the response to the one that Neil Evans forwarded to you last week. Hope this helps. Regards.

Operational Description

Bluetooth radio and baseband operation: a summary Bluetooth operates using frequency hopping spread spectrum techniques (FHSS) with Gaussian frequency shift keying (GFSK). The parameters of these techniques are described in more detail below. For more information please refer to the Radio and Baseband specification chapters of the Bluetooth Core specification at http://www.bluetooth.com/developer/specification/Bluetooth_11_Specifications_Book.pdf Bluetooth channel definition The Bluetooth channel is represented by a pseudo-random hopping sequence hopping through 79 RF channels. The hopping sequence is unique for each piconet (a group of units comprising a master and up to 7 slaves all sharing the same channel) and 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 frequencies. The nominal hop rate is 1600 hops/s. All Bluetooth units participating in the piconet are time- and hop- synchronized to the channel. Time slots The channel is divided into time slots, each 625 ms in length. The time slots are numbered according to the Bluetooth clock of the piconet master. The slot numbering ranges from 0 to 2 27 -1 and is cyclic with a cycle length of 2 27 . In the time slots, master and slave can transmit packets. A time division duplex scheme is used where master and slave alternatively transmit. The master shall start its transmission in even-numbered time slots only, and the slave shall start its transmission in odd-numbered time slots only. The packet start shall be aligned with the slot start. Packets transmitted by the master or the slave may extend over up to five time slots. 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. The RF hop frequency in the first slot after a multi-slot packet shall use the frequency as determined by the current Bluetooth clock value. 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. Modulation and bit rate The data transmitted has a symbol rate of 1 Ms/s. A Gaussian-shaped, binary FSK modulation is applied with a BT product of 0.5. A binary one is represented by a positive frequency deviation, a binary zero by a negative frequency deviation. The maximum frequency deviation shall be between 140 kHz and 175 kHz. Modulation and characteristics The Modulation is GFSK (Gaussian Frequency Shift Keying) with a BT=0.5. The Modulation index must be between 0.28 and 0.35. A binary one is represented by a positive frequency deviation, and a binary zero is represented by a negative frequency deviation. The symbol timing shall be better than ±20 ppm. For each transmit channel, the minimum frequency deviation (Fmin = the lesser of {Fmin+, Fmin-}) which corresponds to 1010 sequence shall be no smaller than ±80% of the frequency deviation (fd) which corresponds to a 00001111 sequence. In addition, the minimum deviation shall never be smaller than 115 kHz. The zero crossing error is the time difference between the ideal symbol period and the measured crossing time. This shall be less than ± 1/8 of a symbol period.

EXHIBIT BB – Processing Gain FCC ID O2Z-BT2 Page 1 of 11 Properties/Title v2 15 February 2001 MEMORANDUM – PROCESSING GAIN REPORT FOR INTEL(R) PERSONAL WIRELESS MODULE 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 Intel(R) Personal Wireless Module 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 Intel(R) Personal Wireless Module “B” Bluetooth chip 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 Intel(R) Personal Wireless Module Bluetooth Chip 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 …
