GLS MT Installation 4/1/2004 VER 2.8 DOC 3 Installation of the Mobile Terminal (MT) on an Aluminum Roof Trailer The following describes the proper materials and steps required for installing the MT on an Aluminum Roof Trailer. Strict adherence to the following procedures is paramount to ensuring a secure and safe installation. Installation Environment Caution! • DO all installations in a clean, dry, and properly prepared environment. Temperature should be maintained above 32°F for a minimum of 30 minutes before and after installation! • DO NOT attempt to install the MT in the rain or fog, or if signs of snow, ice or condensation are evident on the trailer roof. It is extremely important that the mounting surface be clean and dry prior to installing the unit. • Failure to follow these installation procedures could allow the Mobile Terminal to separate from the vehicle resulting in possible injury or death! Materials Required for MT Installation Contact Skybitz Customer Service before making any substitutions to the items listed below: • Skybitz Mobile Terminal Mounting Kit including Bracket with Pre-applied VHB Tape • Skybitz Mounting Hardware kit including 4 ea. Torx #15 Security with a #8- 32 - ½” screws with thread lock, 4 ea. #8 lock washers, and 4 ea. #8 flat washers. • Skybitz Mobile Terminal Safety Tether Kit including tether guard • 3M Primer 94 • Small paint brush (when not using ampoules with integrated applicator) • Medium Duty abrasive pad (Preferred Product - 3M Scotch-Brite Pad #9650) • Clean, lint-free towels or paper towels • 50% to 70% Isopropyl Alcohol and water solution – (Preferred Product - 3M Prep-Solvent 70) • RTV sealing compound • 6ft. of masking tape • Power drill with 3/16” drill bit • Torx security driver bit #15 or Torx security wrench • 1/8” Hex Key Wrench (Safety Tether Screw) • 3/8” open End Wrench (Safety Tether Nut) GLS MT Installation 4/1/2004 VER 2.8 DOC 4 Location of the MT on the Trailer Roof The recommended mounting location on the trailer roof is approximately 3ft. back from the front of the trailer, and about 1ft. in from the left road-side rail. This location is intended to minimize the potential for damage from low hanging tree branches and to maximize the Mobile Terminal’s view of the sky when the trailer is backed into a dock. The Mobile Terminal(with integral antenna used for this transmitter) must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Installing the MT, Mounting Bracket, and Safety Tether 1. Begin by installing the MT and tether loosely to the mounting bracket. Do not fully tighten the MT to the bracket at this time. The MT must be free to float within the bracket at this stage of the installation. Tightening of the MT to the bracket at this time could impede the bonding of the MT bracket to the trailer roof! FRONT MT and Tether Loosely Mounted to Bracket Orient the terminal in the bracket so the screw holes align and the connector is at the open end of the “U”. Install the tether to the MT using a Torx Security stainless steel screw with a lock washer. Insert the screw through the tether tab, then the MT bracket, and into the front roadside hole in the MT. Orient the tab with the tether towards the front of the bracket and partially install the screw leaving the MT free to move in the brac…

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 August 24, 2004 RE: SkyBitz Incorporated FCC ID: SAE-000MTXB After a review of the submitted information, I have a few comments on the above referenced Application. 1) Internal photographs can not simply be held confidential. Further justification must be provided before confidentiality can be granted on this exhibit. Additionally, if only certain pages of this exhibit are to be held confidential, then the exhibit must be separated into 2 parts, one not held confidential, and one that is. 2) For the RF exposure, the device does not require MPE testing and is therefore excluded from this “evaluation” per the FCC rules, not the RF exposure requirements or calculations. Therefore, it is still required that you provide MPE calculations. Please add this information to the current RF exposure exhibit. 3) Users Manual section 4.0 and the test report page 3 of 26 mentions an EIRP of < 2 Watts, while 700 mW + 5.5 dBi given in the MPE evaluation is 2.5 Watts. Please explain (this may be affected in part by #7 below). 4) Please explain the derivation of the 700 mW, since this never appears to have been measured. 5) Is direct antenna conducted measurements possible. If so, the FCC likes also to see the conducted output power measurements on this type of device. Also, other antenna conducted measurements should be provided for spurious if the capability exists. 6) Section 5.0 discusses the installation as normally located > 20 cm, etc. Note that the users manual must specifically instruct how this must be installed and/or used to meet the RF exposure requirements. This type of device should state the following or similar. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. This device must transmit with a source-based time-averaging duty factor not exceeding __% (This part may or may not be applicable). 7) Correction factors are for power and are typically corrected based upon 10(log)(RBW1/RBW2). Please correct data that is affected throughout the report (RF Exposure, power measured, etc.) that may be affected. Note this will likely affect item 3 above. 8) For this type of TX, section III, Items 6(c) and (d) must be filled out on the 731 and match information presented in the application. Please adjust 6(b) for any final EIRP in Watts, due to item 7) above. 9) For Occupied BW - The SA "Reference Level" should be equal to the total power from the transmitter as if you measured it with a power meter and not the maximum emission of the spectrum. Ideally, your bandwidth measurement is relative to the total (or unmodulated power when possible) unless stated in the rules. Additionally, when not specified in the regulations, the occupied bandwidth should be measured at 26 dB down for the FCC (See ANSI C63.4). Therefore your 26dBc points would be down from the reference level - not the peak of your emission. 10) The mean power of spurious emissions shall be attenuated below the mean output power of the transmitter in accordance with 25.202(f). This means the reference level for Figure 2, 3 should be positioned as given in 9) above. Additionally, the measurements should be made using a 4 kHz RBW or larger based upon the requirements. Please comment or correct as necessary. z Page 2 August 24, 2004 11) Please explain where compliance to 25.216(i) may be found. 12) Please explain the DC voltages and currents applied into the several elements of the final radio frequency amplifying device for normal operation over the power range Timothy R.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 August 31, 2004 RE: SkyBitz Incorporated FCC ID: SAE-000MTXB After a review of the submitted information, I have a few comments on the above referenced Application. 1) A stronger justification for the internal photographs being held confidential is necessary as given in an earlier email. 2) Occupied BW was not tested with a 4 kHz or larger RBW as specified in the requirements. Note also that the correction factor you specify is used for amplitude, not bandwidth displacement. You can not simply correct bandwidth for a ratio of RBW used. Additionally only a 300 Hz bandwidth was used, which is not considered close to 4 kHz. Please provide measurements using a >= 4 kHz RBW. For purposes of bandwidth measurements, the 4 kHz should be considered the minimum. 3) The Carrier off state DOES NOT show compliance to 25.215(i) for -80 dBW/MHz and in fact shows over the limit in Figure 4. Also figure 6 & 7 would not apply since compliance was shown for 700 Hz bandwidth measurements, not 1 MHz. Also please note, that we have seen where LO’s increase when the TX is turned off or in an idle state, thus this mode should be investigated. Timothy R.

Further justification must be provided before confidentiality can be granted on this exhibit. Additionally, if only certain pages of this exhibit are to be held confidential, then the exhibit must be separated into 2 parts, one not held confidential, and one that is. R. The letter has been expanded to provide clearer justification. Please see exhibit “000MTXB Cover Letter - RFC Rev 1.pdf”. 2) For the RF exposure, the device does not require MPE testing and is therefore excluded from this “evaluation” per the FCC rules, not the RF exposure requirements or calculations. Therefore, it is still required that you provide MPE calculations. Please add this information to the current RF exposure exhibit. Response to ATCB Comments FCC ID: SAE-000MTXB 2 R. The original MPE exhibit was submitted with incorrect data. A new MPE exhibit containing calculations using measured values has been prepared. Please see exhibit “000MTXB RF Exposure Info – New.pdf”. 3) Users Manual section 4.0 and the test report page 3 of 26 mentions an EIRP of < 2 Watts, while 700 mW + 5.5 dBi given in the MPE evaluation is 2.5 Watts. Please explain (this may be affected in part by #7 below). R. The original MPE exhibit is in error. Please discard this exhibit. 4) Please explain the derivation of the 700 mW, since this never appears to have been measured. R. The actual output power was measured and is reported in the revised test report. Please see exhibit “000MTXB Test Report Rev 1.pdf”. 5) Is direct antenna conducted measurements possible. If so, the FCC likes also to see the conducted output power measurements on this type of device. Also, other antenna conducted measurements should be provided for spurious if the capability exists. R. The device incorporates an integral antenna making conducted measurements at an antenna terminal unachievable. 6) Section 5.0 discusses the installation as normally located > 20 cm, etc. Note that the users manual must specifically instruct how this must be installed and/or used to meet the RF exposure requirements. This type of device should state the following or similar: “The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. This device must transmit with a source-based time-averaging duty factor not exceeding __%.” (This part may or may not be applicable). R. Please see the revised User Manual: exhibit “000MTXB User Manual Rev 1.pdf”, page 4. 7) Correction factors are for power and are typically corrected based upon 10(log)(RBW1/RBW2). Please correct data that is affected throughout the report (RF Exposure, power measured, etc.) that may be affected. Note this will likely affect item 3 above. R. The test report has been revised using a correction bandwidth correction based on 10(log)(RBW1/RBW2). 8) For this type of TX, section III, Items 6(c) and (d) must be filled out on the 731 and match information presented in the application. Please adjust 6(b) for any final EIRP in Watts, due to item 7) above. R. Please see exhibit “000MTXB Application Form - 731 revised.pdf”, which now includes items 6(c) and 6(d). The output power listed is the actual measured power. 9) For Occupied BW - The SA "Reference Level" should be equal to the total power from the transmitter as if you measured it with a power meter and not the maximum emission of the spectrum.

Therefore your 26dBc points would be down from the reference level - not the peak of your emission. R. The bandwidth plot has been corrected to show the 26dB bandwidth of the modulated signal. It was not possible to get an unmodulated signal on this device. 10) The mean power of spurious emissions shall be attenuated below the mean output power of the transmitter in accordance with 25.202(f). This means the reference level for Figure 2, 3 should be positioned as given in 9) above. Additionally, the measurements should be made using a 4 kHz RBW or larger based upon the requirements. Please comment or correct as necessary. R. Since an unmodulated carrier could not be obtained, the attenuation of spurious emissions was based on the modulated carrier, resulting in a worst case condition. The spurious emissions were measured using a RBW close to the 4kHz specified. A correction was applied to the measurement to adjust for the actual measurement bandwidth used. Additionally, the spurious emissions were not detectable using a larger bandwidth setting. 11) Please explain where compliance to 25.216(i) may be found. R. The unit already complies with the -80 dBW requirements of §25.216(d) in the transmit mode as shown in Figures 4 thr…

From: Greg Snyder [mailto:[email protected]] Sent: Tuesday, September 14, 2004 12:00 PM To: '[email protected]' Subject: Part 25.202(f) emission mask To: Lab Help Ref: Measurement Interpretation I have a client with a satellite terminal operating at 1643MHz for which they are trying to get certification under Part 25. The Satellite Provider has an authorized BW of 10kHz for this usage. The unit uses MSK modulation and has a 26dB bandwidth of about 7.2kHz. These parameters are already in use and specified via the satellite provider. The problem arises with the emissions mask specified under Part 25.202(f) when it talks about a "in any 4kHz band". With such a small authorized bandwidth (10kHz) there's no way the emission can comply with the in-band mask when measured with a 4kHz or larger bandwidth. Typically a RBW of 1% or larger of the emission bandwidth is used to measure emissions for emission mask measurement. Attached are 3 plots showing a CW signal from a signal generator measured with varying RBW's of 1kHz, 3kHz and 10kHz in comparison to the Part 25.202 emission mask. Based on a 10kHz authorized BW the CW doesn't comply with the mask using a 3k or 10k RBW. An additional emission mask plot showing the actual signal measured with a 300Hz RBW is also included. Is it acceptable to show compliance with Part 25.202(f) using a resolution bandwidth of 300Hz (>1% of Occupied Bandwidth) for this signal since the authorized bandwidth is only 10kHz?

Document 8183-MPE, Rev. 0 FCC ID: SAE-000MTXB RF Exposure Evaluation Washington Laboratories, Ltd August 2004 Maximum Permissible Exposure Calculations for Skybitz L-Band Mobile Terminal FCC ID: SAE-000MTXB August 30, 2004 WLL PROJECT #: 8183X This report may not be reproduced, except in full, without the prior written consent of Washington Laboratories, Ltd. RF Exposure Evaluation Document 8183-MPE, Rev. 0 FCC ID: SAE-000MTXB RF Exposure Evaluation Washington Laboratories, Ltd August 2004 1 Maximum Permissible Exposure Evaluation for FCC ID: SAE-000MTXB 1.0 Introduction This evaluation has been prepared on behalf of Skybitz Inc. L-Band Mobile Terminal to show compliance with the RF exposure requirements as defined in FCC §1.1307. 1.1 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: ƒ Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. ƒ Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. ƒ Portable Devices: a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). For this test report the Skybitz Inc. L-Band Mobile Terminal is classified as a “Mobile Device” and therefore must meet the limits as specified in §1.307. The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Occupational/Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: Document 8183-MPE, Rev. 0 FCC ID: SAE-000MTXB RF Exposure Evaluation Washington Laboratories, Ltd August 2004 2 ƒ Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. This exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Awareness of the potential for RF exposure in a workplace or similar environment can be provided through specific training as part of a RF safety program. If appropriate, warning signs and labels can also be used to establish such awareness by providing prominent information on the risk of potential exposure and instructions on methods to minimize such exposure risks. ƒ General Population/Uncontrolled Exposure: The general population / uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not considered sufficient to allow the device to be considered under the occupational/controlled category, and the general population/uncontrolled exposure limits apply to these devices. The Skybitz Inc. L-Band Mobile Terminal is evaluated to the General Population/Uncontrolled Exposure limits. 1.2 Radio Frequency Radiation Exposure Evaluation The highest RF output power of the unit was measured at 32.12dBm at 1643 MHz. According to §1.1310 of the FCC rules, the power density limit for General Population/Uncontrolled Exposure is 1mW/cm 2 . As this is a mobile device the MPE shall be calculated at 20cm to show compliance with the power density limit. The following formula was used to calculate the power density at 20cm: 2 4R PG S π = Where: S = Power Density P = Output Power at the Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna Document 8183-MPE, Rev. 0 FCC ID: SAE-000MTXB RF Exposure Evaluation Washington Laboratories, Ltd August 2004 3 For this device, the calculation is as follows: R = 20cm PG = Output Power (EIRP) = 1630 mW )20( 4 )1630( 2 ×× = π S = 0.324 mW/cm 2 (Based on continuous transmission) Based on the calculation above, the device complies with the minimal permissible expos…
