Subject: FCC Certification Authorization Application under FCC PART

15, Subpart C, Sec. 15.247 - Direct Sequence Spread
Spectrum Transmitters operating in the frequency band 2400 -

2483.5 MHz.

Product: PCMCIA WIRELESS LAN CARD
Model No.: WL-211F
FCC ID: MXF-WL211F

Dear Sir or Madam:
As appointed agent for GEMTEK TECHNOLOGY CO., LTD., we would like to

submit the application to the Federal Communications Commission for certification
of the above product. Please review all necessary files uploaded to FCC OET site
for detailed information.

Since the rf exposure safety distance is small (2.4 cm) where the power density
reach 1mW/cm2 and the antenna is enclosed within the case, the RF exposure risk
is in-considerable. Therefore, the applicant wishes to apply for the exemption of the
SAR test requirements. Please kindly refer to the RF Exposure Warning for
compliance with FCC Rule 2.1093 in the “RF Exposure Info” Exhibit and User’s
Manual for detailed information.

Enclosed you will find copy of the engineering report, the necessary documents
and information pertaining to this submission, in addition, please refer to the
multiple listing letters of agreement from Gemtek Technology Co. Ltd. and
NgeeAnn Polytechnic.

If you have any queries, please do not hesitate to contact us.
Yours truly,

6.9.2. Method of Measurements

Refer to Exhibit 8, Sec. 8.4 of this test report and ANSI 63.4-1992, Para. 8 for detailed radiated emissions measurement
procedures.

The following measurement procedures were also applied:

•

Applies to harmonics/spurious that fall in the restricted bands listed in Section 15.205. the maximum permitted

average field strength is listed in Section 15.209. A Pre-Amp and highpass filter are used for this measurement.

•

For measurement below 1 GHz, set RBW = 100 KHz, VBW > 100 KHz, SWEEP=AUTO.

•

For measurement above 1 GHz, set RBW = 1 MHz, VBW = 1 MHz (Peak) & VBW = 10 Hz (Average),

SWEEP=AUTO.

•

If the emission is pulsed, modified the unit for continuous operation, then use the settings above for measurements,

then correct the reading by subtracting the peak-average correction factor derived from the appropriate duty cycle
calculation. See Section 15.35(b) and (c).

TEST BACKGROUND AND PROCEDURE.

According to FCC regulations [1], a direct sequence spread spectrum system must have a processing
gain, Gp of at least 10 dB. Compliance to this requirement can be shown by demonstrating a relative
bit-error-ratio (BER) performance improvement (and corresponding signal to noise ratio per symbol
improvement of at least 10 dB) between the case where spread spectrum processes (coding,
modulation) are engaged relative to the processes being bypassed. In some practical systems, the
spread spectrum processing cannot simply be bypassed. In these cases, the processing gain can be
indirectly measured by a jamming margin test [2]. In accordance with the new NPRM 99-231, if the
vendor has a system with less than 10 chips per symbol, the CW jamming results must be supported
by a theoretical explanation of the system processing gain.

THEORETICAL CALCULATIONS

a form of M-ary Orthogonal Keying. The BER performance curve is given by [5]:

For the case of the HFA3861A, the bit rates are 1, 2, 5.5, and 11 Mbps. The corresponding symbol
rates are 1, 1, 1.375, and 1.375 MSps. The chip rate is always 11 MCps, so the ratio of chip rate to
symbol rate is 11:1 for the 1 and 2 Mbps rates and 8:1 for the 5.5 and 11 Mbps rates. Since the
symbol rate to bit rate is less than 10 for the higher rates, we supply the theoretical processing gain
calculation for these cases where spread spectrum processing gain with embedded coding gain is
utilized. This is reasonable in that they cannot be separated in the demodulation process. If a
separable FEC coding scheme were used, we would not be comfortable making this assertion.

As can be seen from the curve of figure 1, the Es/N0 is 16.4 dB at the PER of 8%. This PER can be
related to a BER of 1e-5 on 1000 byte packets. With 8 bits per symbol, the Eb/N0 is then 7.4 dB or 9
dB less than the Es/N0. It is well known that the Eb/N0 of BPSK is 9.6 dB for 1e-5 BER, so
therefore the coding gain of CCK over BPSK is 2.2 dB. We add this to the processing gain of 9 dB
to get 11.2 dB overall processing gain for the CW jammer test.

Taking the calculations above, if the

Theoretical Process Gain for CCK Modulation

In the case of CCK modulation at higher data rate, the Chip Rate/Symbol Rate (8 dB) is not an actual Process Gain since
it is a combination of both Process gain and Coding Gain. The formula true formula for Processing Gain calculation will
be based on the CW Jamming Margin. Please refer to the attached theoretical Process Gain calculation written by Mr.
Carl Andren at Intersil Corporation for details.

TEST BACKGROUND AND PROCEDURE.

According to FCC regulations [1], a direct sequence spread spectrum system must have a processing
gain, Gp of at least 10 dB. Compliance to this requirement can be shown by demonstrating a relative
bit-error-ratio (BER) performance improvement (and corresponding signal to noise ratio per symbol
improvement of at least 10 dB) between the case where spread spectrum processes (coding,
modulation) are engaged relative to the processes being bypassed. In some practical systems, the
spread spectrum processing cannot simply be bypassed. In these cases, the processing gain can be
indirectly measured by a jamming margin test [2]. In accordance with the new NPRM 99-231, if the
vendor has a system with less than 10 chips per symbol, the CW jamming results must be supported
by a theoretical explanation of the system processing gain.

For the case of the HFA3861A, the bit rates are 1, 2, 5.5, and 11 Mbps. The corresponding symbol
rates are 1, 1, 1.375, and 1.375 MSps. The chip rate is always 11 MCps, so the ratio of chip rate to
symbol rate is 11:1 for the 1 and 2 Mbps rates and 8:1 for the 5.5 and 11 Mbps rates. Since the
symbol rate to bit rate is less than 10 for the higher rates, we supply the theoretical processing gain

calculation for these cases where spread spectrum processing gain with embedded coding gain is
utilized. This is reasonable in that they cannot be separated in the demodulation process. If a
separable FEC coding scheme were used, we would not be comfortable making this assertion.

As can be seen from the curve of figure 1, the Es/N0 is 16.4 dB at the PER of 8%. This PER can be
related to a BER of 1e-5 on 1000 byte packets. With 8 bits per symbol, the Eb/N0 is then 7.4 dB or 9
dB less than the Es/N0. It is well known that the Eb/N0 of BPSK is 9.6 dB for 1e-5 BER, so
therefore the coding gain of CCK over BPSK is 2.2 dB. We add this to the processing gain of 9 dB
to get 11.2 dB overall processing gain for the CW jammer test.

Taking the calculations above, if the

8.2. METHOD OF MEASUREMENTS - AC MAINS CONDUCTED EMISSIONS

•

AC Mains conducted emissions measurements were performed in accordance with the standard against appropriate

limits for each detector function.

•

The test was performed in the shielded room, 16'(L) by 16'(W) by 12'(H).

•

The test was performed were made over the frequency range from 450 kHz to 30 MHz to determine the line-to-

ground radio noise voltage which was conducted from the EUT power-input terminals that were directly connected to
a public power network.

•

The EUT normally received power from another device that connects to the public utility ac power lines,

measurements would be made on that device with the EUT in operation to ensure that the device continues to comply
with the appropriate limits while providing the EUT with power.

•

If the EUT operates only from internal or dedicated batteries, with no provisions for connection to the public utility

ac power lines, AC Mains conducted measurements are not required.

•

Table-top devices were placed on a platform of nominal size 1 m by 1.5m raised 80 cm above the conducting ground

plane.

•

The EUT current-carrying power lead, except the ground (safety) lead, was individually connected through a LISN to

the power source. All unused 50-Ohm connectors of the LISN was terminated in 50-ohm when not connected to the
measuring instruments.

•

The line cord of the EUT connected to one LISN which was connected to the measuring instrument. Those power

cords for the units of devices not under measurement were connected to a separate multiple ac outlet. Drawings and
photographs of typically conducted emission test setups were shown in the Test Report. Each current-carrying
conductor of the EUT shall be individually tested.

•

The EUT was normally operated with a ground (safety) connection, the EUT was connected to the ground at the

LISN through a conductor provided in the lead from the ac power mains to the LISN.

•

The excess length of the power cord was folded back and forth in an 8-shape on a wooden strip with a vertical prong

located on the top of the LISN case.

•

The EUT was set-up in its typical configuration and operated in its various modes as described in this test report.

•

A preliminary scan was made by using spectrum analyzer system with the detector function set to PEAK mode (9

KHz RBW, VBW > RBW), frequency span 450 kHz to 30 MHz.

•

The maximum conducted emission for a given mode of operation was found by using the following step-by-step

procedure:

Step1. Monitor the frequency range of interest at a fixed EUT azimuth.
Step2. Manipulate the system cables and peripheral devices to produce highest amplitude signal relative to the

limit. Note the amplitude and frequency of the suspect signal.

Step3. The effects of various modes of operation is examined. This is done by varying equipment operation

modes as step 2 is being performed.

Step4. After completing step 1 through 3, record EUT and peripheral device configuration, mode of operation,

cable configuration, signal levels and frequencies for final test.

•

Each highest signal level at the maximized test configuration was zoomed in a small frequency span on the spectrum

analyzer's display (the manipulation of cables and peripheral devices and EUT operation modes might have to be
repeated to obtain the highest signal level with the spectrum analyzer set to PEAK detector mode 10 KHz RBW and
VBW > RBW). The spectrum analyzer was then set to CISPR QUASI-PEAK detector mode (9 KHz RBW, 1 MHz
VBW) and AVERAGE detector mode (10 kHz RBW, 1 Hz VBW). The final highest RF signal levels and
frequencies were record.

Broad-band ac Powerline conducted emissions:- If the EUT exhibits ac Powerline conducted emissions that exceed

the limit with the instrument set to the quasi-peak mode, then measurements should be made in the average mode. If
the amplitude measured in the quasi-peak mode is at least 6 dB higher than the amplitude measured in the average
mode, the level measured in quasi peak mode may be reduced by 13 dB before comparing it to the limit.

for that combination.

§

The following method of measurement shall apply to both conducted and radiated measurements.

§

The radiated measurements are performed at the Ultratech Calibrated Open Field Test Site.

§

The measurement shall be performed using normal operation of the equipment with modulation.

Test procedure shall be as follows:

Step 1: Duty Cycle measurements

Ø

capture the envelope peaks and the duty cycle of the transmitter output signal;

Ø

The duty cycle of the transmitter, x = Tx on / (Tx on + Tx off) with 0<x<1, is measure and recorded in the test

report. For the purpose of testing, the equipment shall be operated with a duty cycle that is equal or more than

0.1.

Step 2: Calculation of Peak and Average EIRP

Ø

The peak output power of the transmitter shall be determined using a wideband, calibrated RF Peak Power

Meter with the power sensor with an integration period that exceeds the repetition period of the transmitter by a
factor 5 or more. The observed value shall be recorded as “P” (in dBm);

Ø

The Average EIRP. shall be calculated from the above measured power output “A”, the observed duty cycle x,

and the applicable antenna assembly gain “G” in dBi, according to the formula:

Peak EIRP = P + G
Average EIRP = Peak EIRP + 10log(1/x)

8.4. SPURIOUS EMISSIONS (CONDUCTED & RADIATED)

For both conducted and radiated measurements, the spurious emissions were scanned from the lowest frequency
generated by the EUT or 10 MHz whichever is lower to 10th harmonic of the highest frequency generated by the EUT.

8.4.1. Spurious Emissions (Conducted)

•

The radio was connected to the measuring equipment via a suitable attenuator.

•

The spectrum analyzer were used and set as follows:

- Resolution BW: 100 kHz

- Video BW: same or greater

- Detector Mode: Positive Peak

- Averaging: Off

- Span: 100 MHz

- Amplitude: Adjust for middle of the instrument’s range

- Sweep Time: Auto

•

The radiated emission measurements were performed at the UltraTech’s 3 Meter Open Field Test Site (OFTS)

situated in the Town of Oakville, province of Ontario. The Attenuation Characteristics of OFTS have been filed to
FCC, Industry Canada, ACA/Austel, NVLap and ITI.

•

The frequencies of emissions was first detected. Then the amplitude of the emissions was measured at the specified

measurement distance using required antenna height, polarization, and detector characteristics.

•

During this process, cables and peripheral devices were manipulated within the range of likely configuration.

•

For each mode of operation required to be tested, the frequency spectrum was monitored. Variations in antenna

heights (from 1 meter to 4 meters above the ground plane), antenna polarization (horizontal plane and vertical plane),
cable placement and peripheral placement were explored to produce the highest amplitude signal relative to the limit.

The maximum radiated emission for a given mode of operation was found by using the following step-by-step
procedure:

Step1: Monitor the frequency range of interest at a fixed antenna height and EUT azimuth.
Step2: Manipulate the system cables to produce highest amplitude signal relative to the limit. Note the amplitude

and frequency of the suspect signal.

Step3: Rotate the EUT 360 degrees to maximize the suspected highest amplitude signal. If the signal or another at

a different frequency is observed to exceed the previously noted highest amplitude signal by 1 dB or more,
go back to the azimuth and repeat Step 2. Otherwise, orient the EUT azimuth to repeat the highest amplitude
observation and proceed.

Step4: Move the antenna over its full allowable range of travel (1 to 4 meters) to maximize the suspected highest

amplitude signal. If the signal or another at a different frequency is observed to exceed the previously noted
highest amplitude signal by 1 dB or more, return to Step 2 with the highest amplitude observation and
proceed.

Step5: Change the polarization of the antenna and repeat Step 2 through 4. Compare the resulting suspected highest

amplitude signal with that found for the other polarization. Select and note the higher of the two signals.
This signal is termed the highest observed signal with respect to the limit for this EUT operational mode.

Step6: The effects of various modes of operation is examined. This is done by varying the equipment modes as

steps 2 through 5 are being performed.

Step7: After completing steps 1 through 6, record the final highest emission level, frequency, antenna polarization

and detector mode of the measuring instrument.

Calculation of Field Strength:

The field strength is calculated by adding the calibrated antenna factor and cable factor, and subtracting the Amplifier
gain (if any) from the measured reading. The basic equation with a sample calculation is as follows:

FS = RA + AF + CF - AG

Where FS = Field Strength

RA = Receiver/Analyzer Reading
AF = Antenna Factor
CF = Cable Attenuation Factor
AG = Amplifier Gain

Example: If a receiver reading of 60.0 dBuV is obtained, the antenna factor of 7.0 dB/m and cable factor of 1.0 dB are

added, and the amplifier gain of 30 dB is subtracted. The actual field strength will be:.

Field Level = 60 + 7.0 + 1.0 - 30 = 38.0 dBuV/m.
Field Level = 10

(38/20)

= 79.43 uV/m.

8.5. TRANSMITTED POWER DENSITY OF A DSSS SYSTEM

•

The radio was connected to the measuring equipment via a suitable attenuator.

•

Locate and zoom in on emission peak(s) within the passband

•

The spectrum analyzer were used and set as follows:

- Resolution BW: 3 kHz

- Video BW: same or greater

- Detector Mode: Normal

- Averaging: Off

- Span: 3 MHz

- Amplitude: Adjust for middle of the instrument’s range

- Sweep Time: 1000 seconds

•

Locate and zoom in on emission peak(s) within the passband. Set RBW = 3 KHz, VBW > RBW, Sweep = SPAN/3

KHz. For example, a span of 1.5 MHz, the sweep should be 1.6x106/3.0x103= 500 seconds. The measured peak level
must be no greater than +8 dBm.

•

For devices with spectrum line spacing greater than 3 KHz no change is required.

•

For devices with spectrum line spacing equal to or less than 3 KHz, the resolution bandwidth must be reduced below

3 KHz until the individual lines in the spectrum are resolved. The measurement data must then be normalized to 3
KHz by summing the power of all the individual spectral lines within 3 KHz band (in linear power units) to
determine compliance.

•

If the spectrum line spacing cannot be resolved on the available spectrum analyzer, the noise density function on

most modern conventional spectrum analyzer will directly measure the noise power density normalized to 1 Hz noise
power bandwidth. Add 30 dB for correction to 3 KHz.

•

Should all the above fail or any controversy develop regarding accuracy of measurement, the Laboratory will use HP

89440A Vector Signal Analyzer for final measurement unless a clear showing can be made for a further alternate.

8.6. PROCESSING GAIN OF A DIRECT SEQUENCE SPREAD SPECTRUM

The processing gain may be measured using the CW jamming margin method. Figure 1 shows the test configuration. The
test consists of stepping a signal generator in 50 KHz increments across the passband of the system. At each point, the
generator level required to produce the recommended Bit Error Rate (BER) is recorded. This level is jammer level. The
output power of the transmitting unit is measured at the same point. The Jammer to Signal (J/S) ratio is then calculated.
Discard the worst 20% of the J/S data points. The lowest remaining J/S ratio is used when calculating the Process Gain.

The signal to noise ratio for an ideal differentially coherent detection of a differentially encoded BPSK receiver can be
derived from the Bit Error Probability (Pb) versus Signal-to-Noise ratio. See attached plot for detailed information.

For measurement of the (S/N)o we use the Pb of 1.0x10-5 minimum.

Ref.: Viterbi, A.J. Principles of Coherent Communications (New York: McGraw-HILL 1966), Pg. 207

Using equation (1) shown above, calculate the signal to noise ratio required for your chosen BER. This value and the
measured J/S ratio are used in the following equation to calculate the Process Gain (Gp) of the system.

Gp = (S/N)o+Mj+Lsys

Where:

(S/N)o: Theoretical signal to noise ratio required to maintain the normal operation just before the BER

appears. In real measurements the maximum error of 0.001 is allowed in an ideal system using
their modulation scheme with all codes turned off (i.e. no spreading or processing gain).

Mj: Maximum jammer to Signal Ratio that recorded at the detected BER.

Lsys: System losses such as non-ideal synchronization, tracking circuitry, non-optimal baseband receiver

filtering and etc... These losses can be in excess of 3 dB for each transmitter and receiver pair. For
the purpose of this processing gain calculation we assume a Lsys at its minimum value of 2 dB.

Ref.: Dixon, R, Spread Spectrum Systems. (New York: Wiley, 1984), Chapter 1.

•

(S/N)o: Refer to attached curves, BER versus (S/N)o for Differential Coherent Detection of Differentially Encoded

BPSK

Processing gain Gp = (S/N)o + Lsys + Mj = (S/N)o + 2 + Mj
