 9. Frequency Stability

    9.1 Limits

         Manufactures of U-NII devices are responsible for ensuring frequency stability such
         that an emission is maintained within the band of operation under all conditions of
         normal operation as specified in the users manual.

    9.2 Test SET-UP (Block Diagram of Configuration)

                                                           Power Source


    9.3 Test Procedure

         1. The EUT was placed inside the environmental test chamber and powered by
            Power source.
         2. Turn the EUT on and couple its output to a spectrum analyzer.
         3. Turn the EUT off and set the chamber to the highest temperature specified.
         4. Allow sufficient time (approximately 30 min) for the temperature of the chamber to
            stabilize, turn the EUT on and measure the operating frequency after 2, 5, and 10
            minutes.
         5. Repeat step 2 and 3 with the temperature chamber set to the lowest temperature.
         6. The chamber was allowed to stabilize at +20 degree C for a minimum of 30
            minutes. The supply voltage was then adjusted on the EUT from 85% to 115% and
            the frequency record.
            Note: The EUT set at un-modulation mode during frequency stability test.

10.2 Measurement Procedure

a. Blow 1GHz, the EUT was placed on the top of a rotating table 0.8 meters above the ground
   at a 3 meter semi- anechoic chamber room.
b. For the radiated emission test above 1GHz:
   The EUT was placed on the top of a rotating table 1.5 meters above the ground at a 3 meter
   full anechoic chamber room. The table was rotated 360 degrees to determine the position of
   the highest radiation. Place the measurement antenna away from each area of the EUT
   determined to be a source of emissions at the specified measurement distance, while
   keeping the measurement antenna aimed at the source of emissions at each frequency of
   significant emissions, with polarization oriented for maximum response. The measurement
   antenna may have to be higher or lower than the EUT, depending on the radiation pattern of
   the emission and staying aimed at the emission source for receiving the maximum signal.
   The final measurement antenna elevation shall be that which maximizes the emissions. The
   measurement antenna elevation for maximum emissions shall be restricted to a range of
   heights of from 1 m to 4 m above the ground or reference ground plane.
c. The EUT was set 3 meters away from the interference-receiving antenna, which was
   mounted on the top of a variable-height antenna tower.
d. The height of antenna is varied from one meter to four meters above the ground to
   determine the maximum value of the field strength. Both horizontal and vertical polarizations
   of the antenna are set to make the measurement.
e. For each suspected emission, the E UT was arranged to its worst case and then the antenna
   was tuned to heights from 1 meter to 4 meters and the rotatable table was turned from 0
   degrees to 360 degrees to find the maximum reading. The test-receiver system was set to
   peak detect function and specified bandwidth with maximum hold mode.
f. A Quasi-peak measurement was then made for that frequency point for below 1GHz test.
   PK and AV for above 1GHz emission test.

        Remark:(1) Emission level (dB)V = 20 log Emission level V/m
               (2) The smaller limit shall apply at the cross point between two
                   frequency bands.
               (3) As shown in 15.35(b), for frequencies above 1000MHz, the
                   field strength limits are based on average detector, however,
                   the peak field strength of any emission shall not exceed the
                   maximum permitted average limits, specified above by more
                   than 20dB under any condition of modulation.
               (4) The frequency range scanned is from the lowest radio
                   frequency signal generated in the device which is greater than
                   9 kHz to the tenth harmonic of the highest fundamental
                   frequency or 40 GHz, whichever is lower.
               (5) §15.247(d) specifies that emissions which fall in the restricted
                   bands, as defined in §15.205 comply with radiated emission
                   limits specified in §15.209.

  11. Antenna Application

    11.1 Antenna requirement

      According to of FCC part 15C section 15.203:

      An intentional radiator shall be designed to ensure that no antenna other than that
      furnished by the responsible party shall be used with the device. The use of a
      permanently attached antenna or of an antenna that uses a unique coupling to the
      intentional radiator, the manufacturer may design the unit so that a broken antenna can
      be replaced by the user, but the use of a standard antenna jack or electrical connector is
      prohibited. The structure and application of the EUT were analyzed to determine
      compliance with section 15.203 of the rules.

      And according to 47 CFR section 15.407(a), if the transmitting antennas of directional
      gain greater than 6dBi are used, the transmit power and power spectral density shall be
      reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi.



    11.2 Measurement Results

     The EUT has two external antennas, which are:

    As the antenna connectors of EUT are non-standard and the antennas are specified above
    by manufacturer; it is considered to meet the standard requirements.
