Request for Confidentiality Date: November 8, 2013 Subject: Confidentiality Request for: FCC ID: VJB-OPTICOMGPS3 IC ID: 7275A-OPTICOM3 Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit Short Term Permanent Block Diagrams Short Term External Photos Short Term Permanent* 1 Internal Photos Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Parts List & Placement/BOM Short Term Permanent Tune-Up Procedure Short Term X Permanent Schematics Short Term Test Setup Photos Short Term Permanent* User’s Manual Global Traffic Technologies LLC has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of N/A days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. NOTE for Industry Canada Applications: The applicant understands that until such time that IC distinguishes between Short Term and Permanent Confidentiality, either type of marked exhibit above will simply be marked Confidential when submitted to IC. 1 - The asterisked items (*) require further justification before permanent confidentiality will be allowed. These also currently require review by the FCC under their Permit-But-Ask policy before the grant is issued and can delay completion of an application. Further justification should be added to the note above. One such example for a potted device would be: “The EUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable damage to internal circuitry. See photographs exhibits that outline the device before and after potting.”

The discriminator output is connected to an A/D converter. The A/D converter samples the discriminator output using multiple samples per bit. The A/D converter is connected to a high speed data port (uPP) on the processor. The Omap processor recovers the data using signal processing algorithms. The first IF frequency is 110.59 MHz and the second IF is 10.7 MHz. 2.2.2 Transmitter In order to duplicate the modulation of the legacy system without the need for tuning, the modulation is performed digitally. The processor calculates the in-phase and quadrature components of the signal. The signal is transferred to a pair D/A converters which directly modulates the RF carrier signal. The output of the RF modulator is bandpass filtered, and then drives the RF power amplifier. The frequency of the oscillator the feeds the modulator is at the TITLE: GTT Module Theory of Operation DATE: 1/9/14 FILENAME: GTT Theory of Operation.docx REVISION: 2.0 PAGE: Page 5 of 6 transmit frequency. The RF amplifier output is lowpass filtered before connecting to the antenna. Output power is adjustable by means of a programmable attenuator following the modulator but before the power amplifier. 2.2.3 Channel Selection Frequency selection is by means of an integrated phase lock loops and local oscillators. The three oscillators will only have to tune to a new hop frequency and not from receiver IF frequency to transmit frequency during the frame. Since this only has to be done once per frame, it allows longer tuning time and lower phase noise of the oscillators. PSEUDORANDOM HOPPING SEQUENCE. A new hop channel is selected every 333ms. 2 50 58 4 52 6 8 60 10 48 42 12 46 44 40 62 38 64 14 16 66 18 32 20 68 22 30 72 1 74 34 36 24 28 26 3 70 53 5 55 59 9 49 7 47 51 11 45 61 13 63 41 39 15 43 65 19 37 67 69 17 21 73 31 29 33 71 75 27 35 25 23 56 57 54 RECEIVER SYNCHRONIZATION AND RECEIVER INPUT BANDWIDTH.
