1 Introduction
Qualcomm's technologies powered the smartphone revolution and connected billions of people.
We pioneered 3G and 4G – and now we are leading the way to 5G and a new era of intelligent,
connected devices. Our products are revolutionizing industries, including automotive, computing,
IoT, healthcare and data center, and are allowing millions of devices to connect with each other in
ways never before imagined. Qualcomm Incorporated includes our licensing business, QTL, and
the vast majority of our patent portfolio. Qualcomm Technologies, Inc., a subsidiary of Qualcomm
Incorporated, operates, along with its subsidiaries, all of our engineering, research and
development functions, and all of our products and services businesses, including, our QCT
semiconductor business. For more information, visit Qualcomm’s website, OnQ

This experimental license request would support a small communication network contained within
a 500-foot radius on Qualcomm’s campus in Sorrento Valley, California. The network will be
used for research and development of advanced wireless communications systems utilizing wide
transmission bandwidths.

The frequency range of 2.9-3 GHz will support experimental development only and this band is
not targeted for future wireless communication deployment.


2 Experiment Description
Qualcomm has designed a low power communications network to provide RF coverage within a
500-foot radius for purposes of developing next generation wideband wireless technologies
around several Qualcomm buildings in the Sorrento Valley area of San Diego.

The low power research and development network is summarized as:
    5 outdoor sites with directional antennas and maximum EIRP= 1W/100MHz (-50dBm/Hz)
    1 indoor fixed site with an omni antenna and maximum EIRP= 1W/100MHz (-50dBm/Hz)
    Up to 20 mobile units, each with a maximum EIRP= 0.4W/100MHz (-54 dBm/Hz) that
       operate within the fixed RF coverage area.

The fixed site physical locations are shown in Figure 1 with the specific location parameters
defined in Table 1. Mobile units will operate anywhere within the defined 500-foot radius.

As shown in Figure 2, the network has been specifically designed to keep the required RF energy
localized in the development area around the identified Qualcomm buildings. Some design
considerations include:
     Directional antennas are utilized to direct RF into the coverage
     Many antennas are orientated into the sides of large buildings greater than 5 stories tall
        to reduce RF propagation outside the coverage area.
     When possible, physical antenna down tilt has been used to reduce propagation to the
        horizon direction.

Table 2 lists the maximum transmit power of the fixed and mobile devices in the range of 2.9-3
GHz. Transmission is a 100 MHz bandwidth OFDM signal occupying the full 2.9-3 GHz.
