Exhibit I The proposed experimentation involves feature testing and Wi-Fi coexistence evaluation of a new cellular system that additionally utilizes the unlicensed frequencies to enhance the overall system capacity and provide better telecommunication experience. We are planning to install two Smallcell eNodeB base stations inside a building in Austin with mobile handset units being tested in and around that building. The eNodeB base stations will be operating on the LTE band 4 (B4) as well as the UNII-1 and UNII-3 bands. The base station antennas could be directional but the testing would point the antennas in 0 to 360 degrees in horizontal plane and -5 to -10 degrees in vertical plane. The equipment will be provided by manufacturers such as Ericsson and Nokia in compliance with the LTE-Unlicensed (LTE-U) and LTE-License Assisted Access (LTE-LAA) specifications. This experimentation is expected to report as to how well the LTE-U/LTE-LAA and Wi-Fi can coexist under the test conditions and also provide a measure of performance of the LTE-U/LTE-LAA system. The experimentation results will pave the way for utilization and/or improvement of the LTE-U/LTE-LAA specifications. These frequencies have been coordinated with the FCC. The FAA Coordination Numbers are: • NG T160223 • NG T160224 1
