Marianne Bosley From: Chris Harvey [[email protected]] Sent: Friday, August 13, 2004 2:01 PM To: 'Chris Harvey'; 'Jenny Chen' Cc: [email protected]; 'william chua'; Chris Harvey Subject: RE: Additional information needed Nakamichi MT#15846 8/13/2004 Jenny, per our phone conversation this morning I looked back into the technical information for this Nakamichi application and find that the Report seems to document Frequency Hopping capability. The information provided during the phone conversation seemed to imply that this device is not a FHSS system. You indicated that this device operates using Amplitude Shift Key (ASK) modulation. In FCC 15.247 for operation at 2.4GHz band you can either be a FHSS device or a Digital Transmission System (DTS). FHSS devices must comply with the following sections: 15.247(a)(1), 15.247(a)(1)(iii) , 15.247(b)(1, 2 & 4), 15.247(g), 15.247(h) DTS (Digitally Modulated Systems) must comply with the following sections: 15.247(a)(2), 15.247(b)(3), 15.247(c), 15.247(d) The original request was to show compliance with the 15.247(a)(1) and 15.247(a)(iii) and 15.247(h): 3) Please provide the following items defining the FHSS operation of this device: a) Is the hopping sequence pseudorandom, based on the technical description? (Op Description states random but predictable) b) Is each channel used equally on average, based on the technical description? c) Does the associated system receiver have a compliant input bandwidth, based on the measured 20 dB emission bandwidth? d) Does the associated system receiver have the ability to hop in synchronization with the transmitter, based on the technical description? e) Does the frequency hopping system comply with the non-coordination requirement? Please either address the questions above or show that this device complies with all the requirements for a Digitally Modulated System (DTS). If this is a DTS device, please amend the test report to show compliance with the DTS requirements listed earlier in this e-mail. I think the confusion in this application is that the test report seems to partially document compliance as an FHSS device and partially as a DTS device. I look forward to your reply to clarify the intent of this application and exhibits.

The response for Question #3 does not address the questions being asked. From the description provided this does not sound like Frequency Hoipping Spread Spectrum. Please ask the customer for assistance in providing full technical response to the specific questions to determine if this device operates using the FCC definitions of FHSS (by the way Bluetooth devices do meet the FCC definition, but I do not see in the documentation that this device meets the Bluetooth requirements). I am still awaiting the manual revision with the RF Exposure statements per question #4. Please note that each attachment must be uploaded. In the future, please try to submit one PDF file for each exhibit type. So for example, please submit one PDF document for the Schematic exhibit. When you submit 20 separate exhibits, even if they are zipped into a compressed folder, this causes much extra work when uploading these documents to the FCC. There is a 4MB file size restriction, so please make sure to reduce the resolution to that necessary to view the file correctly if file size is an issue.

The Wireless Transceiver module. The wireless Transceiver module is a digital wireless audio module which operates in ISM Band. The module consists of a master and one or more slaves. The Master sends audio stream data and the slaves receive the audio stream data. Main Features : • 4: 1 Audio Compression and Decompression. • Supports 16/24-bit stereo audio format. • Supports 44.1 KHz/ 48KHz sampling frequency. • Modulation Mode : o Frequency Hopping Spread Spectrum (FHSS) o Adaptive Frequency Selection (AFS) • Use 2.4GHz ISM Band • Forward Error Correction • Device ID setting • Operation voltage: 4.5V to 7V. Modulation Mode : Frequency Hopping Spread Spectrum (FHSS) is a transmission technology used in WLAN transmissions where the data signal is modulated with a narrowband carrier signal that "hops" in a random but predictable sequence from frequency to frequency as a function of time over a wide band of frequencies. But device using this hopping method receives a lot of interference from other devices that use 2.4GHz range frequency such as WLAN, and also from other Bluetooth devices that resides near it. FHSS, being built to avoid interfering with other devices, rather interferes a lot with devices that has high output power using 2.4GHz frequency range and with other FHSS devices. Therefore, the wireless Transceiver module also has adopted improved frequency hopping method called Adaptive Frequency Selection (AFS). During the initialization, the module scans 79 channels and selects the clear, non-interfered, and reliable channel and starts the communication between the master and slave. During the channel link, if the channel becomes unreliable and the error detection from FEC block exceeds the preset error threshold value, the module executes setup scanning, as in initialization, and reselects new clear and reliable channel. Through this method, high quality wireless audio can be achieved by avoiding any interference from WLAN, and other 2.4GHz frequency range devices. Device ID Setting To establish communication channel properly, hopping frequency and Syncword of each packet should be determined by Device ID(Identification). Device ID is unique value of each device, master and slaves. Only master and slaves with same Device ID can communicate each other. Device ID can be set manually in case selected master and slaves do not communicate together. With this the security of the transceiver can be achieved.
