 1.2         EUT Description
 The Qualcomm LAA Release 13 Small Cell Model: MTP9900 is a 2x2 Tx system that uses two LTE carriers to
 transmit simultaneously in a licensed band and an unlicensed band. It is also possible to transmit on a 40MHz
 channel by using both LTE carriers in the unlicensed band at the same time. The test hardware SKU
 identification number is 65-F5230-910. For this MPE evaluation, the power density is determined from the
 highest measured conducted power in LTE and LAA modes along with the addition of a 6dBi max antenna
 gain.

1.3         MPE Requirements Overview
Three different categories of transmitters are defined by the FCC KDB 447498 D01 v06. These categories are
fixed installation, mobile, and portable and are defined as follows:

      o     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.

      o     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.

      o     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).

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:

      o     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.

      o     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 Qualcomm LAA Release 13 Small Cell FCC ID: J9CMTP9900LAA is evaluated to the Mobile Device
requirements and is considered a device to be used by the General Population/Uncontrolled Exposure.

1.4         Procedure
The procedure used to determine the RF power density was based upon a calculation for determining
compliance with the MPE requirements. The power generated by each antenna output used in this product
was initially measured by a spectrum analyzer and the powers were recorded. Through use of the Friis
transmission formula and knowledge of the maximum 6dBi antenna gain to be used, the power density level is
calculated at a distance of 20cm.

Friis Transmission Formula

Friis transmission formula: Pd = (Pout*G) / (4πr2)

Where,

Pd = Power Density (mW/cm2)                              π = 3.1416
Pout = output power to antenna (mW)                      r = distance between observation point and center of the radiator (cm)
G = gain of antenna in linear scale

Calculated MPE

The power density limit for General Population/Uncontrolled Exposure at each frequency is determined based
on the information in Table 1-1.

There is no co-location between the electric fields of any two transmitters therefore following power densities
are calculated for each individual transmitter by frequency at 20cm spacing:

1.5         Simultaneous Transmission
Simultaneous transmission results are calculated by adding the highest EIRP in LTE Band 2 or Band 4 and
adding it to the highest 5GHz EIRP to compare with its respective power density limits. This is performed for
both chains such that a total of 4 transmitters are active.
