Exhibit I Applicant seeks a two (2) year experimental license to conduct functional testing and propagation measurements for evaluating the viability of spectrum in the 3.4-4.2 GHz and millimeter wave bands to support fifth generation wireless communication systems (“5G systems”) and validating 5G system designs operating on that spectrum. The industry standards organization, 3rd Generation Partnership Project (“3GPP”), is currently developing 5G standards, which are expected for release beginning in 2018. The testing initially performed under this experimental license will provide valuable information for optimizing 5G system parameters being discussed in 5G standard activities and provide data on coverage, capacity, latency, and other key performance indices. AT&T intends to utilize this data both for studying potential designs for its own 5G systems as well as for contributing to the 3GPP 5G standards development process. Later testing will include evaluations of 5G systems based upon 3GPP 5G standards after they are released. 5G systems will utilize advanced antenna technologies with beamforming and multiple in multiple output (“MIMO”) technology, as well as more efficient coding and modulation schemes. These technologies are expected to result in higher spectral efficiencies, reduce latency to 1-5 milliseconds, and enable gigabyte per-second (Gbps) mobile and fixed broadband services, significantly faster than today’s average 4G speeds using long term evolution (“LTE) connections. The testing will involve communications between a fixed outdoor base station at 9825 Spectrum Drive, Austin TX 78717 and user equipment (“UEs”) operated from inside residential units, business units, and test vehicles located within three (3) kilometers of the base station. The 5G radio signal will be measured and analyzed in various types of radiofrequency (“RF”) propagation environments (e.g. line-of-sight, through foliage, built-up nearby structures, etc.). Applicant will coordinate with American Spectrum Resources, Inc. (“ASRI”) prior to performing any testing to insure non-interference to other operators in the 3.7-4.2 GHz bands. 1
