Box 358315 Pittsburgh, PA 15251-5315 Re: Certification request for the Symbol model LA-4111 Wireless LAN PCMCIA card FCC ID: H9PLA4111 Date: September 28, 1999 To The Commission: This certification request is for the Spectrum 24 model LA-4111 PCMCIA WLAN Module. The LA4111 is a 2.4 GHz direct sequence 11 Mb/s transceiver incorporated into a PCMCIA package. This request is for certification of a Part 15 transciever composite device consisting of integrated transmitter operating under 15.247(c) and receiver operating under 15.247(b). 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.

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 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

Also, Provide the official DOC Certificate because the Certificate in the report was blank with no name, address etc... and was not signed. A new corrected label was uploaded to the OET web site. An error occurred when converting the DOC report to electronic format. The completed and signed DOC Certificate page was incorporated into the DOC report and uploaded to the OET web site. 3) Provide a list of antennas. For each antenna, indicate the model number, antenna gain, the output power and the total EIRP. Provide a photo for each antenna or antenna specification sheet for each antenna.

From:Joe Dichoso [email protected] FCC Application Processing Branch Re:FCC ID H9PLA4111 Applicant:Symbol Technologies Inc Correspondence Reference Number:11692 731 Confirmation Number:EA95624 Date of Original E-Mail:01/28/2000 1) I did not understand your response to the output power discrepancy. It appears that the device can operate at 100 mW and 500 mW and the device was only tested at 60 mW. Please explain. Can the device operate at higher output power? Additional tests may be required. The device is a 60 mW device only. Due to miscommunication between engineering and technical publications the preliminary version of the users manual misstated the power level of the device. As shown in the response to 11167 all mention of power level has been removed from it. 2) The DOC label exhibit was unreadable. Please resubmit it. Done. Conf. No. EA95624Correspondence Ref. 11692 3) Verify that the list of antennas provided is complete. Antenna #'s 7,8,13 and 14 were not listed or shown in the photo's. Please explain. In the antenna section for these particular antennas I stated “Not certified with this radio”. Perhaps a better choice of words is “Not submitted with this device”. The antenna list is complete without 7, 8, 13, and 14. 4) The RF safety exhibit has never been submitted. Please provide it and place it in the RF exposure info folder. In correspondence number 11149 paragraph 4 you state “The RF exposure information identified 19 antennas, .....” I will submit a new RF Exposure Info attachment. Hopefully it will not generate more confusion. I hope these answers are satisfactory. Respectfully, Norman H. Nelson

It is available from Amphenol through distributors but not commercial electronic parts retailers. Special tools and advanced assembly skills are necessary to attach this connector to a cable. The Amphenol part number is 908-43300. Drawings of these connectors are attached. The other end of the coaxial cable is attached to a polarized BNC connector. The polarized BNC connector is similar to a regular BNC type connector but is made unique by swapping the inner conductor sex. This connector and its mate can be purchased from the manufacturer, M/A COM Inc. A drawing of this connector is attached. In some cases the coax cable is directly soldered to the antenna. The following antennas are options for antennas for the LA 3000/4000 family of WLAN PC Cards. Spectrum 24© RF Exposure Safety: Symbol Technologies, Inc. uses a uniform approach across our line of Spectrum 24© Wireless LAN devices. Spectrum 24© utilizes PC cards that can be purchased in either a 100mW or 350mW versions at 1 and 2 MB/s or 60 mW at 11 MB/s. All antennas in the Spectrum 24 family are compliant with exposure levels when used with the highest output power radios. Symbol Technoloiges, Inc. bases its conformance to safe RF exposure limits on its two worst case situations using the 350 mW version of the PC card using the same antennas as the 100 mW version. The worst case situations for RF exposure are the Parabolic Grid for mobile devices and the body worn WWC1049 terminal with internal1040 antenna. Both use the high power version of the PC Card H9PLA3021-500. MPE distance Calculations Calculations of the MPE distance for each antenna are based on using equation (3) of OET Bulletin 65. Equation (3) was used instead of equations (11) through (18) for ease of computation justified by the fact that equation (3) leads to calculations of higher field strength and a greater MPE distance. All distances are calculated using 350 mW, the worst case situation across the Spectrum 24© product line R=SQRT(PG/4πS)S=1mW/cm2 P=350mWG=10^(9.5 dBi/10)=8.9 R=SQRT(350*8.9/4π)=15.7cm In the case of the Parabolic Grid the MPE distance is 15.7 cm.
