Bluetooth technology has potential for widespread use within the Department of Defense and the Air Force. An office environment using Bluetooth technology can wirelessly connect computers, printers, and other office equipment in order to share information over short distances. The clutter and annoyance of cables connecting equipment can be eliminated. Bluetooth provides a standard interface for connection, as opposed to many different proprietary cables. The research is conducted indoors in a climate controlled environment, with minimal obstructions, to closely follow free-space signal propagation. Four different antenna orientations are used. The factors varied are the distance between devices, and the antenna orientation. This research determined that two of the four cards tested have a specific distance where a change from Data High rate packets and Data Medium rate are used. The change occurs at 2 meters for one and 3 meters for the other. This research also shows that manufacturers transmit identical data in identical formats. Also, this research shows that antenna orientation, and receiver signal strength indicator values have no predictive value in determining packet type used for transmission.
