      1.1    Reason for amendment.

             This report has been modified to include the following sentence in
             section 2.0:

             “The EUT uses the same radio card and the same RF section for both the
             5.7GHz and 4.9GHz band.”

             Bandwidth measurements were repeated on 30 December 2009 with a
             video bandwidth of 1MHz.

             This report includes and makes obsolete both NCEE Labs report
             R101309-02-02 and R101309-02-02A.

2.0     EUT Description
The Equipment Under Test (EUT) was an wireless network adapter PCI module capable
of multi-band operation including 802.11 a, a turbo, b, g and g turbo. This functionality
of the EUT is covered by NCEE Test Report R101309-02-01. This report covers only
operation in the Public Safety Band from 4960MHz to 4980MHz. The EUT uses the
same radio card and the same RF section for both the 5.7GHz and 4.9GHz band.

       2.3    EUT Setup
       The EUT was tested on an adapter board. The board included two transmitters,
       only one was active. The EUT was set to operate on the highest and lowest
       frequency (Channel 40 and 80) in the 4.9GHz emergency band. Only the
       functionality of these frequencies were tested and covered in this report.

       2.4     Objective
       This report is prepared on behalf of 3e Technologies Int. in accordance with Part
       2 and Part 90 of the Federal Communication Commission’s rules. The objective
       of the manufacturer is to determine compliance with FCC rules for output
       power, power spectral density occupied bandwidth and spurious emissions.

     Test Result:          Complies                       Date: 2 Dec 2009

     Test Description
     Per FCC §2.1046 and §90.205, the maximum power spectral density of the
     transmitter for mobile station is 21.00dB/MHz.

     Test Environment
     Testing was performed at the NCEE Labs Lincoln facility. Laboratory
     environmental conditions varied slightly throughout the test:
            Relative humidity of 40 ± 5%
            Temperature of 20 ± 2º Celsius

     Test Setup
     The RF output of the transceiver was connected to a spectrum analyzer through
     20dB attenuators. The spectrum analyzer was used to make power spectral
     density measurements. The resolution bandwidth and video bandwidths were
     set to 1MHz, and the frequency span set to 15MHz. The plots on the following
     page include all correction factors from attenuation.

     Test:                 FCC §2.1049, §90.209, §90.210

     Test Result:          Complies                     Date: 30 Dec 2009

     Test Description
     The occupied bandwidth is required to be less than the maximum authorized
     bandwidth of 50MHz.

     Test Setup
     The RF output of the transmitter was connected to the input of the receiver in
     spectrum analyzer mode through sufficient attenuation. The resolution
     bandwidth was set at 1 kHz and the bandwidth was measured 20dB below from
     the peak emission.

     Test Environment
     Testing was performed at the NCEE Labs Lincoln facility. Laboratory
     environmental conditions varied slightly throughout the test:
            Relative humidity of 40 ± 5%
            Temperature of 20 ± 2º Celsius

     Test:                  FCC §2.1051 and §90.210

     Result:                Complies                    Date: 2 Dec 2009

     Test Description
     On any frequency removed from the center of the assigned channel by more
     than 150 percent at least: 53 + 10 log (P) dB = -34.40dBm. Emissions must also
     comply with Mask M from Part 90.210.

     Test Environment
     Testing was performed at the NCEE Labs Lincoln facility. Laboratory
     environmental conditions varied slightly throughout the test:
            Relative humidity of 40 ± 5%
            Temperature of 20 ± 2º Celsius

     Test Setup
     The RF output of the transceiver was connected to a spectrum analyzer through
     appropriate attenuation. The resolution bandwidth of the spectrum analyzer was
     set at 300 kHz. Sufficient scans were taken to show any out of band emissions
     up to 40GHz. The test setup can be seen in Figures 2 through 4 of appendix A.

     Test Results
     The spurious emissions at the antenna terminals were found to comply with FCC
     §2.1051 and §90.210.

     3.5       Spurious Emission

     Test:                 FCC §2.1053 and §90.210

     Result:               Complies                       Date: 20 Nov 2009

     Test Description
     The measurement antenna was placed at a distance of 10 meters from the EUT.
     During the tests, the antenna height and polarization as well as EUT azimuth
     were varied in order to identify the maximum level of emissions from the EUT.
     The test was performed by placing the EUT on 3-orthogonal axis. The frequency
     range up to 40GHz was investigated.

     The EUT was then removed and the replaced with a substitution antenna of the
     same model as the receiving antenna. A signal generator was connected to the
     substitution antenna by a non-radiating cable. The absolute levels of the spurious
     emissions were measured by the substitution. Spurious emissions in dB = 10 log
     (TXpwr in Watts/0.001) which is the absolute level.

     Test Environment
     Testing was performed at the NCEE Labs Lincoln facility in the 10m semi-
     anechoic chamber. Laboratory environmental conditions varied slightly
     throughout the test:
            Relative humidity of 40 ± 5%
            Temperature of 20 ± 2º Celsius

     Test Setup
     The transmitter was placed on a wooden turntable, and it was transmitting into a
     non-radiating load which was also placed on the turntable.

     Test Results

      Notes:
         1. Cable factor from signal generator to transmit antenna is less than 1dB.
         2. Antenna and cable factor for the receiving antenna are taken into account in the
             pre-scan level.
         3. Limit = 10 log (TXpwr in Watts/0.001)

3.6       Carrier Frequency Stability

Test:                    FCC §90.213

Test Method:             TIA-603-C, Section 3.2.2

Result:                  Complies                     Date: 20 Nov 2009


Tested per TIA-60-C:2004. Conducted power was measured on a spectrum analyzer
with resolution bandwidth and video bandwidth set to 100KHz. The center frequency
was found by measuring the frequency of the signal 10dB below the peak on the high
and low end of the signal. The frequency half way in between these frequencies was
recorded as the center frequency. The EUT support board is supplied by 5VDC. This
input voltage was varied by (+/-)15% for each temperature setting.

          Test Setup:




          Test Procedure:

          Channel 40 nominal: 4960.000MHz
          Channel 80 nominal: 4980.000MHz

          Allowed deviation: 0.494MHz
          Channel 40: 4959.510 – 4960.494MHz
          Channel 80: 4979.510 – 4960.494MHz

          See the standard for test procedures.
