2.0             PRODUCT INFORMATION

2.1         Equipment Description
The Equipment Under Test (EUT) is the LG Portable Handset FCC ID: ZNFD415. The test data contained in
this report pertains only to the emissions due to the EUT’s WLAN (DTS) transmitter.

2.2         Device Capabilities
This device contains the following capabilities:

850/1900 GSM/GPRS/EDGE, 850/1700/1900 WCDMA/HSPA, 802.11b/g/n WLAN, Bluetooth (1x, EDR, LE)

Note: 5GHz WLAN (DTS/NII) operation is possible in 20MHz, 40MHz, and 80MHz channel bandwidths. The
maximum achievable duty cycles for all modes were determined based on measurements performed on a
spectrum analyzer in zero-span mode with RBW = 8MHz, VBW = 50MHz, and detector = peak per the
guidance of Section 6.0 b) of KDB 558074 v03r01. The RBW and VBW were both greater than 50/T, where T
is the minimum transmission duration, and the number of sweep points across T was greater than 100. The
duty cycles are as follows:

3.0             DESCRIPTION OF TEST

3.1         Evaluation Procedure
The measurement procedures described in the American National Standard for Testing Unlicensed Wireless
Devices (ANSI C63.10-2009), and the guidance provided in KDB 558074 v03r01 were used in the
measurement of the LG Portable Handset FCC ID: ZNFD415.

Deviation from measurement procedure…………………………………………….....................................None

3.2         Radiated Emissions
The radiated test facilities consisted of an indoor 3 meter semi-anechoic chamber used for final measurements
and exploratory measurements, when necessary. The measurement area is contained within the semi-
anechoic chamber which is shielded from any ambient interference. For measurements above 1GHz
absorbers are arranged on the floor between the turn table and the antenna mast in such a way so as to
maximize the reduction of reflections. For measurements below 1GHz, the absorbers are removed. An ETS
Lindgren Model 2188 raised turntable is used for radiated measurement. It is a continuously rotatable, remote-
controlled, metallic turntable and 2 meters (6.56 ft.) in diameter. The turn table is flush with the raised floor of
the chamber in order to maintain its function as a ground plane. A 78cm high PVC support structure is placed
on top of the turntable. A ¾” (~1.9cm) sheet of high density polyethylene is used as the table top and is placed
on top of the PVC supports to bring the total height of the table to 80cm.

For all measurements, the spectrum was scanned through all EUT azimuths and from 1 to 4 meter receive
antenna height using a broadband antenna from 30MHz up to the upper frequency shown in 15.33(b)(1)
depending on the highest frequency generated or used in the device or on which the device operates or tunes.
For frequencies above 1GHz, linearly polarized double ridge horn antennas were used. For frequencies below
30MHz, a calibrated loop antenna was used. When exploratory measurements were necessary, they were
performed at 1 meter test distance inside the semi-anechoic chamber using broadband antennas, broadband
amplifiers, and spectrum analyzers to determine the frequencies and modes producing the maximum
emissions. Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them
to warm up to their normal operating condition. The test set-up was placed on top of the 0.8 meter high, 1 x
1.5 meter table. The EUT, support equipment, and interconnecting cables were arranged and manipulated to
maximize each emission. Appropriate precaution was taken to ensure that all emissions from the EUT were
maximized and investigated. The system configuration, clock speed, mode of operation or video resolution, if
applicable, turntable azimuth, and receive antenna height was noted for each frequency found.

Final measurements were made in the semi-anechoic chamber using calibrated, linearly polarized broadband
and horn antennas. The test setup was configured to the setup that produced the worst case emissions. The
spectrum analyzer was set to investigate all frequencies required for testing to compare the highest radiated
disturbances with respect to the specified limits. The turntable containing the EUT was rotated through 360
degrees and the height of the receive antenna was varied 1 to 4 meters and stopped at the azimuth and height
producing the maximum emission. Each emission was maximized by changing the orientation of the EUT
through three orthogonal planes and changing the polarity of the receive antenna, whichever produced the
worst-case emissions. For the EUT positioning, “H” is defined with the EUT lying flat on the test surface, “H2”
is defined with the EUT standing up on its side, and “V” is defined with the EUT standing upright.

6.2         Radiated Spurious Emission Measurements
§15.247(d) / §15.205 & §15.209; RSS-210 [A8.5]

Test Overview and Limit

All out of band radiated spurious emissions are measured with a spectrum analyzer connected to a receive
antenna while the EUT is operating at its maximum duty cycle (>98%), at maximum power, and at the
appropriate frequencies. All data rates and modes were investigated for radiated spurious emissions. Only the
radiated emissions of the configuration that produced the worst case emissions are reported in this section.

All out of band emissions appearing in a restricted band as specified in Section 15.205 of the Title 47
CFR must not exceed the limits shown in Table 6-2 per Section 15.209.

Test Notes

      1. The optional test procedures for antenna port conducted measurements of unwanted emissions per
            the guidance of KDB 558074 v03r01 were not used to evaluate this device for compliance to radiated
            limits. All radiated spurious emissions levels were measured in a radiated test setup.
      2. All emissions lying in restricted bands specified in §15.205 are below the limit shown in Table 6-10.
      3. The antenna is manipulated through typical positions, polarity and length during the tests. The EUT is
            manipulated through three orthogonal planes.
      4. This unit was tested with its standard battery.
      5. The spectrum is measured from 9kHz to the 10th harmonic of the fundamental frequency of the
            transmitter using CISPR quasi peak detector below 1GHz. Above 1 GHz, average and peak
            measurements were taken using linearly polarized horn antennas. The worst-case emissions are
            reported however emissions whose levels were not within 20dB of the respective limits were not
            reported.
      6. Emissions below 18GHz were measured at a 3 meter test distance while emissions above 18GHz
            were measured at a 1 meter test distance with the application of a distance correction factor.
      7. Average levels at -135dBm and peak levels at -125dBm represent the analyzer noise floor and signify
            that no emission was detected.

Sample Calculations

            Determining Spurious Emissions Levels

            o     Field Strength Level [dBV/m] = Analyzer Level [dBm] + 107 + AFCL [dB/m]
            o     AFCL [dB/m] = Antenna Factor [dB/m] + Cable Loss [dB]
            o     Margin [dB] = Field Strength Level [dBV/m] – Limit [dBV/m]


            Radiated Band Edge Measurement Offset

             o     The amplitude offset shown in the radiated restricted band edge plots in Section 6.8 was
                   calculated using the formula:
                   Offset (dB) = (Antenna Factor + Cable Loss + 10 dB Attenuator) – Preamplifier Gain
