Box 358315 FAX: (408) 528-2740 Pittsburgh, PA 15251-5315 [email protected] Re: Certification request for the Symbol model DM4046 WLAN DS Radio Module Date: December 18, 2000 To The Commission: This certification request is for the Spectrum 24 model DM4046 WLAN DS Radio Module. The DM4046 is a 2.4 GHz direct sequence IEEE 802.11 compliant transceiver. The DM4046 is configured in a form factor for installation into two different models of Voice Over IP wireless phones. This request is for Limited Modular Approval of a Part 15 transmitting device operating under 15.247(c) and its associated antennas. Symbol is requesting a Limited Modular Approval for this device. This device meets seven of the eight requirements for modular approval. This device does not meet requirement #3 for onboard voltage regulation. This device will only be installed into end products with the necessary voltage regulation to ensure that the end product remains compliant. Symbol Technologies, Inc. manufactures information systems that are employed in commercial establishment to assist in controlling inventory. Spectrum 24 is a Wireless Local Area Network (WLAN) used along with hand held computers to assist in information collection typically in retail stores, warehouses, and factories. The following files are electronically submitted as attachments.

There are 3 antennas included in this submission. The radio board is used in two wireless voice communication devices. One of them uses one antenna and the other uses the remaining two antennas. Symbol Technologies, Inc. ("Symbol"), requests that the Block Diagram, Schematics, and Operational Description Exhibits of the above referenced application be withheld from routine availability for public DM4046 Cover Letter.doc Page 2 of 2 inspection pursuant to Section 0.459 of the Commissions Rules and Freedom of Information Act ("FOIA") Exemption 4, 5 U.S.C. 552(b)(4). These exhibits consist of "trade secrets [or] commercial or financial information obtained from a person and privileged or confidential", 5 U.S.C. 552(b)(4), and is therefore entitled to protection from disclosure under FOIA. The documents in question contain trade secrets: detailed technical descriptions, specifications and schematics for a product to be offered for sale. These materials provide particulars on the product design that can be ascertained from inspection of the product itself only with extraordinary expenditures of time and effort, if at all. This information would give Symbol's would-be competitors an unearned and unwarranted competitive advantage. Moreover, the documents contain "commercial information" within the scope of FOIA Exemption 4. This information is the product of Symbol's investment of money, personnel, and other resources. The result of that investment is a fairly earned position in the marketplace. Premature release of the information threatens substantial and unwarranted harm to Symbol's competitive position. For these reasons, Symbol has taken pains to keep this technical information confidential, and intends to continue doing so. Symbol customarily withholds this information from persons outside the employ of Symbol and certain of its suppliers and contractors, and even within these groups routinely limits access to persons having a particular need for the information. If the Commission were to make these documents public, it would be giving away hard won fruits of Symbol's labors without compensation. The filing fee required for this request is submitted by credit card account as entered on Form 159 mailed under separate cover. If there are any questions about this request, please call me at the number above. Thank you for your attention. Respectfully submitted, Norman H. Nelson

Answer: The LMA request letter is loaded. 3 Question Provide process gain data at the highest data rate for each chip/symbol ratio. What are the data rates and chip/symbol ratios? Do not submit copies of process gain data unless you verify that the device is electrically identical to the device tested for Process gain measurements. Answer: The DM4046 RF and base band processing are identical to the LA4021 WLAN PC Card. The PCB layouts and parts are the same. I have loaded the processing gain test as a test report. 4 Question Provide the theoretical process gain (spread rate/data rate) for each data rate. Answer: Please see the loaded processing gain test report. 5 Question There are discrepancies regarding RF safety. The device is a portable device not a mobile device. Provide SAR data, user manual RF safety information. Provide the manual for each phone. Answer: The SAR reports are loaded. Both phone Quick Reference Guides are loaded. The regulatory addenum for the QRG's is loaded. 6 Question For both devices, do they have provisions for belt use, body worn use, accessories such as headphones etc... which will affect the SAR requirements other than use of the devices as a headphone? Submit the RF exhibits into the RF exposure info folder of the filing. Answer: The phones are for hand use and belt use. All configurations were tested for the SAR reports as listed therein.

This module meets the following requirements of DA 00-1407: 1) The module has its own shielding so that it does not rely on the installed device for emissions shielding and to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. 2) The module has buffered digital inputs. The buffering is performed by a custom ASIC chip. 3) The module does not have its own voltage regulation. This is why we are requesting a LMA. The module will only be installed in products that have the necessary voltage regulation circuitry. 4) The antenna couplings are unique. Either a special spring makes contact with the sleeve of the screw in stud antenna or a Hirose FL series coaxial connector is used. 5) The transmitter was tested in a stand-alone configuration. 6) The modular transmitter is labeled with its own FCC ID number. 7) The modular transmitter complies with the specific rules of Part 15.247. Symbol Technologies will only integrate this module so there are no instructions to be submitted. 8) The modular transmitter complies with any applicable RF exposure requirements. A SAR test report for all configurations is included with this application.

Answer: Please change the FCC identifier from H9PDM4046 to H9PNP4046. 2 Question The label must be corrected and submitted. Answer: Please see the uploaded corrected label. 3 Question The the SAR report lists the "Stick on" antenna as 0 dBi while the latest exhibit lists it as 2 dBi. Answer: The SAR report is incorrect. The correct gain for the "Stick on" antenna is 2 dBi. 4 Question Indicate whether the device transmits simultaneously on both antennas when the "Stick on" antenna is installed. Answer: The device only transmits on one antenna at a time. 5 Question The RF safety needs revision. Remove the word Warning. Since SAR was tested, revise the statements to include only the following To comply with RF safety requrirements use the specific belt clip. All other belt clips should be avoided and may not comply with RF safety requirements. Answer: Please see the uploaded revised Regulatory Addendum. Page 1 of 1 Friday, June 15, 2001 01:54 PM

Confirm that they are the same exact transciever. Answer: The FCC ID is H9PLA4121. They are the same transciever. 1. The transmitters are the same. 2. The receivers are the same. The only difference between the devices are the outline of the PCB and parts of the digital control sections. Although the outline of the PCB is different the layer stackup and thicknesses are the same. I have included a picture of each transceiver so that you may compare them.

The duty cycle is the ratio of the maximum transmitter on time divided by the total cycle time which is composed of the maximum on time and the minimum off time. The maximum on time is dependent on the data rate. The 802.11 spec mandates what the maximum data payload for a packet may be. The data pay load along with packet addressing and other network overhead information determine the maximum size of a packet. The maximum transmitter on time is the longest time that it will take the radio to transmit the packet. In the case of Symbol’s Spectrum 24 products the 1 Mbps data rate is the slowest. For the cycle time the minimum off time consists of an acknowledgement from the receiver, the shortest carrier sense time and the shortest packet construction time. The acknowledgment an…
