EXHIBIT 2 This program of research and experimentation is a wireless CDMA communications system. We will utilize small terminals with a CDMA Modem, up and down converter with an IF of 70 MHz and RF output of 20 or 30 GHz and directional antennas. In addition, we will utilize the Advanced Communications Technology Satellite (ACTS) to conduct our satellite experiments. This experiment will help us to validate our link budget and our CDMA waveform. This CDMA Communications system is technologically state of the art. When complete it will utilize less radio frequency bandwidth and great flexibility to provide users with an integration of multiple services such as voice, data and video anywhere, anytime.
