O2Z-BT1Ambler Bluetooth Module

EXHIBIT TT - Response to Item #1 FCC ID O2Z-BT1 1.0 Eligibility Requirements for Regulatory Module Approval As part of Intel’s solution for Bluetooth wireless technology in mobile PCs, Intel will provide regulatory approvals for certain countries in the form of a Module Approval (MA) grant, which can be utilized by PC manufacturers. This section lists the requirements that must be met in order for Intel’s customers to utilize the MA grant. The Intel MA applies only to computer laptop devices. The MA grant is not authorized for any other electronic devices. The Intel Ambler module with Bluetooth wireless technology is a radio device that transmits and receives radio signals in accordance with the spectrum regulations for the 2.4-GHz unlicensed frequency range. Regulatory approval is required for each country throughout the world where the end-user wishes to operate the Ambler module and communicate to other Bluetooth devices. There are two methods by which Intel customers may obtain regulatory approvals for their platform designs: standard type approval for radio transmitters or the MA. The MA is only valid in countries that have accepted the MA process. For countries that have not accepted the MA process, PC manufacturers must submit the laptop for a conventional radio transmitter “type approval” for each country of interest. PC manufacturers may disregard the requirements of this section if they accept the full responsibility for regulatory-type approval of the electronic device with an integrated Ambler module. 1.1 User Guide Information PC manufacturers are required to place specific text in the user’s guide for a notebook PC alongside other regulatory information. The information may be segmented by geographic world region if desired, but the exact text shown below must be maintained. The user’s guide must contain the following items: United States of America Requirements The following text must be copied exactly into the products user’s guide: “This device 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 undesired operation. Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.” General Requirements The following text must be copied exactly into the product’s user’s guide: “This product contains a radio transmitter with Bluetooth wireless technology which has been tested and found to be compliant with the applicable regulations governing a radio transmitter in the 2.400 GHz to 2.4835 GHz frequency range. The countries where this product is authorized for sale and use by Intel are: United States of America Belgium Germany Italy Netherlands Spain Sweden Switzerland United Kingdom Sale or use in any other country is not authorized by Intel and is the sole responsibility of the notebook PC manufacturer.” 1.2 Exterior Laptop Labeling An FCC label, along with specific text, must be placed on the notebook PC that contains an Intel Ambler module with Bluetooth wireless technology. The following exact text must be placed beneath the FCC label on the exterior of the laptop. “Contains one of the Transmitter Modules” FCC ID: To be determined FCC ID: To be determined 1.3 Design Requirements To be eligible to utilize the Intel MA grant, the Intel Ambler module with Bluetooth wireless technology must be designed into the notebook PC following certain design requirements. These requirements are listed below. General The Intel Ambler module with Bluetooth wireless technology may not be altered or modified in any way upon receipt from Intel. Additionally, no external component can be added which changes the radio frequency (RF) characteristics of the transmitted signals. This includes all components both passive and active such as RF filters, RF amplifiers, RF switches, etc. RF components may not be placed between the output pin of the Ambler module and the Intel enabled antennas except the RF transmission line that interconnects them. Antennas Only antennas selected by Intel may be used with the Intel Ambler module with Bluetooth wireless technology. These antennas are designed to be compatible with the RF transmission line impedance and frequency range of the Intel Ambler module with Bluetooth wireless technology. These antennas may not be modified in any way from the design baseline as indicated by the antenna data sheets from the manufacturer. The antennas selected by Intel have been specifically tested with the Intel Ambler module with Bluetooth wireless technology, and they are certified through the regulatory agencies indicated in section 1.1.2 for authorized use. Use of antennas in a platform other than the antennas selected by Intel voids the MA grant for that platform. Transmission Line Interconnection There are specific requirements that must be met when designing a transmission line interconnection between the Intel Ambler module with Bluetooth wireless technology and the antennas. The Intel Ambler module with Bluetooth wireless technology has been specifically designed as a miniature component to be integrated into portable electronic devices. As such the RF connection is not a standard connector, but a ball grid array solder connection. The module should be mounted on a PCB directly or mounted in a specially designed socket that is mounted to a PCB. 1.3.1.1 Impedance The transmission line must be designed to be a 50-Ohm impedance. 1.3.1.2 Physical Implementation [This specific physical implementation of the transmission line interconnection is Intel confidential] 1.4 OEM Regulatory Compliance Instructions The Intel MA may be used by the OEM manufacturers if the manufactures strictly adhere to all items in Sections 1.1 through 1.3. Below are the instructions that must be followed to comply with the…

EXHIBIT J – Description of Frequency Hopping System FCC ID O2Z-BT1 The Equipment Under Test (EUT) is the Intel Corporation Ambler Bluetooth  module, a spread spectrum transmitter that uses frequency hopping modulation. This device is intended to be sold to Original Equipment Manufacturers (OEMs) for integration into laptop computers. This device will be integrated with one of five Intel sponsored antennas which are being recommended to be used with this device. The module will allow laptop computers to communicate with other consumer electronics containing Bluetooth  devices. This will allow a laptop computer to communicate to and share files and data with other devices such as digital cameras, cellular phones, wireless mice, wireless joysticks, wireless keyboards, etc. Within the Bluetooth  protocol, frequency hopping is governed by one and only one Bluetooth  unit in any given communications group. The master unit determines the pseudo random hopping sequence and conveys this information to other “slave” units that are in the communications group with the master. Because the master unit generates the hopping sequence independently without any external information, there is no coordination with other FHSS systems. The Bluetooth  protocol relies on Forward Error Correction (FEC) along with re- transmissions to accommodate for multiple transmitters and interference on specific frequencies. Under two specific modes (page mode and inquiry mode) of the Bluetooth  protocol, fewer than 75 hopping frequencies are used for a very short period of time. These two modes are used to search for and acquire new devices in the surrounding area. The amount of time that a Bluetooth  device spends in these two modes represents a very small portion of the overall communications time. The data transmitted during these two modes is Direct Sequence modulated. Even though the transmitter is still hopping to a pseudo-random hopping sequence (less than 75 frequencies), the data transmitted at each frequency is Direct Sequence modulated. In this regard, the transceiver qualifies as a Hybrid System under the Part 15.247 rules. Because the Bluetooth  protocol contains these modes, and because these modes do not meet the minimum number of hopping channels specified in Part 15.247, the Bluetooth  transmitter is categorized as a Hybrid system for these two modes and the hybrid-mode processing gain calculations apply. Because the Bluetooth ? protocol contains these modes, and because these modes do not meet the minimum number of hopping channels specified in Part 15.247 for frequency hopping, the Bluetooth ? transmitter is categorized as a hybrid system for these two modes and the hybrid- mode processing gain calculations apply. Frequency Bands and Channel Arrangement29 November 199919 BLUETOOTH SPECIFICATION Version 1.0 Bpage 19 of 1082 Radio Specification 2 FREQUENCY BANDS AND CHANNEL ARRANGEMENT The Bluetooth system is operating in the 2.4 GHz ISM (Industrial Scientific Medicine) band. In a vast majority of countries around the world the range of this frequency band is 2400 - 2483.5 MHz. Some countries have however national limitations in the frequency range. In order to comply with these national limitations, special frequency hopping algorithms have been specified for these countries. It should be noted that products implementing the reduced frequency band will not work with products implementing the full band. The products implementing the reduced frequency band must therefore be consid- ered as local versions for a single market. The Bluetooth SIG has launched a campaign to overcome these difficulties and reach total harmonization of the frequency band. Channel spacing is 1 MHz. In order to comply with out-of-band regulations in each country, a guard band is used at the lower and upper band edge. GeographyRegulatory RangeRF Channels USA, Europe and most other countries 1) Note 1. Japan, the MPT announced at the beginning of October 1999 that the Japanese frequency band would be extended to 2400-2483.5 MHz, effective immediately. Testing of devices by TELEC may however need some time to change. The previ- ously specified special frequency-hopping algorithm covering 2471-2497 MHz remains as an option. 2.400-2.4835 GHzf=2402+k MHz, k=0,...,78 Spain 2) Note 2. There is a proposal in Spain to extend the national frequency band to 2403- 2483.5 MHz. The Bluetooth SIG has approached the authorities in Spain to get a full harmonization. The outcome is expected by the beginning of year 2000. 2.445-2.475 GHzf=2449+k MHz, k=0,...,22 France 3) Note 3. The Bluetooth SIG has established good contacts with the French authorities and are closely following the development of harmonization. 2.4465-2.4835 GHzf=2454+k MHz, k=0,...,22 Table 2.1: Operating frequency bands GeographyLower Guard BandUpper Guard Band USA2 MHz3.5 MHz Europe (except Spain and France)2 MHz3.5 MHz Spain4 MHz26 MHz France7.5 MHz7.5 MHz Japan2 MHz2 MHz Table 2.2: Guard Bands Physical Channel29 November 199943 BLUETOOTH SPECIFICATION Version 1.0 Bpage 43 of 1082 Baseband Specification 2 PHYSICAL CHANNEL 2.1 FREQUENCY BAND AND RF CHANNELS Bluetooth operates in the 2.4 GHz ISM band. Although globally available, the exact location and the width of the band may differ by country. In the US and Europe, a band of 83.5 MHz width is available; in this band, 79 RF channels spaced 1 MHz apart are defined. In Japan, Spain, and France, a smaller band is available; in this band, 23 RF channels spaced 1 MHz apart are defined. 2.2 CHANNEL DEFINITION The channel is represented by a pseudo-random hopping sequence hopping through the 79 or 23 RF channels. The hopping sequence is unique for the piconet 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 d…

EXHIBIT QQ – Response to Items #5 & 6 FCC ID O2Z-BT1 . . . . . . . . . . . . . . . . . . . . . . . . . Int e l Corporation Dear Application Examiner: I. The following is in response to Item 5 of your email to us on 7/25/2000, summarized as follows: “With the device in the acquisition mode, it is a Hybrid transmitter. The dwell time in the acquisition mode was not submitted. Hybrid transmitters must also comply with Section 15.247(a)1. Please address the requirements in this Section. What is the channel separation. How is the hop sequence derived and supply an example of a sequence. How are the frequencies used equally. What is the receiver input bandwidth and how does the receiver synchronize to the acquisition signal?” a) Dwell time in the acquisition mode: Please refer to Figures 4, 5, and 6 for Page Mode operation and Figures 7, 8, and 9 for Inquiry mode operation. These figures are part of the file described as “Supplemental Test Report1A.pdf” which has been forwarded and attached to the application filing for this equipment. An individual transmission on a channel in page mode is 182 microseconds long. During a 12.8 sec time period, the total dwell time on a given channel is 116.5 milliseconds in page mode. In inquiry mode, an individual transmission on a channel is 182 microseconds long. During a 12.8 second time period, the total dwell time on a given channel is 98.5 milliseconds in inquiry mode. The following analyzer settings were used. Span = 0 centered on hopping channel Resolution Bandwidth = 1 MHz Video Bandwidth =Resolution Bandwidth Sweep = as necessary to capture the entire dwell time per hopping channel Detector = peak Trace = max hold b) Channel Separation: Response: By system architecture channels are 1 MHz apart c) Derivation of Hop Sequence: Response: The pseudorandom sequence is generated in a nine-stage shift register whose 5 th and 9 th stage outputs are added in a modulo-two addition stage with the result fed back to the input of the first stage. This produces a pseudorandom sequence length of 31 bits for page and inquiry modes and provides for transition to a 511 bit pseudorandom sequence length for data mode of operation. 2200 Mission College Blvd. P.O.
