This experimental license request is in support of a small 5G R&D development and demonstration
network contained planned for operation within a 0.5-mile radius of Qualcomm’s campus in Sorrento
Valley area of San Diego, California. The R&D network will utilize two 100 MHz transmission bandwidths
within the frequency range of 4.4-4.94 GHz.

The requested frequency range of 4.4-4.94 GHz is for technology development purposes only and not
targeted for future non-federal wireless communication deployment in the United States.


2 Experiment Description
The network supported by this experimental license is critical for Qualcomm to develop, validate, and
then demonstrate 5G technology wireless communications systems.

Qualcomm designed the network to generate the smallest amount of RF interference to incumbents in the
requested frequency range while also providing the RF coverage area required for engineering
development and showcasing advanced wireless technology for indoor, outdoor, static and mobility user
environments. The network is required to support both conventional passive antennas configurations as
well as advanced beam forming technologies that will be utilized by 5G networks.

Deliberate placement and positioning of directional antennas limit the usable engineering RF test
coverage area to a 0.5-mile radius. Although the EIRP for the fixes sites has been reduced below target
EIRP values proposed by 5G network operators, Qualcomm anticipates the carefully designed network
will still provide the required engineering value need for the technology development goals.

The network utilizes four fixed sectors to provide the RF coverage area to a maximum of 30 mobile
devices anywhere within the 0.5-mile coverage area. Three of the locations utilize one directional
antenna while the third site has two directional antennas. The mobile devices can be used in static
locations, in vehicles, or in human mobility scenarios. Most mobile testing occurs at ground level but
some mobiles may on occasion be located inside buildings exceeding one story.

The intent is to operate the networks 24 hours per day, 7 days per week.

3 Transmitter Information
The test network utilizes a single TDD 100 MHz channel bandwidth transmitted in the range of 4.4-4.94
GHz at a fixed center frequency. The license requests a frequency range wider than a 100 MHz
frequency span to provide center frequency flexibility if needed to address technical or interference

   challenges that may occur during testing. The intent is to identify at least two 100MHz channel
   bandwidths within the frequency range for testing. Both fixed and mobile transmitters use OFDM
   modulation with a FCC emission designator of 100M00W7W.

   Table 1 describes the technical parameters of the four fixed sites required for the network that are located
   on three different buildings. Building “AY” has two directional antennas while the other three sites have
   only one directional antenna. The EIRP in Table 1 represents the highest EIRP MIMO beamforming
   operation mode of operation resulting from the achieved beamforming array gain. The EIRP is lower
   when operating in a non-beamforming mode.

   The directional fixed site antennas planned for use have not been selected but are planned to follow the
   antenna pattern shown in Figure 1 when operating in a beamform configuration. In the beamforming
   mode, the 3dB beamwidth is anticipated to be approximately 8° in elevation and approximately 2° in
   azimuth while tracking a target receiver. Without beamforming, the 3dB beamwidth is approximately 8° in
   elevation and approximately 74° in azimuth. In both cases, the front to back lobe ration is expected to
   exceed 20dB. Mobile devices use omni directional antennas.

   Figures 2 shows the test network area location in San Diego and Figure 3 provides a visual of the
   resulting RF coverage area required for the engineering activities.
