  • RF audio distribution system including IR presence detection
    Patent number: 8195091
    Abstract: A teacher microphone (30) is provided with an infrared (IR) transmitter to signal a connection request to a wireless audio access point (50) using a first IR request inquiry signal (331). In response to this first IR code, the wireless audio access point establishes a first RF communication link (300). After the first RF communication link is established, the teacher microphone conditionally transmits a first IR presence signal (332) to verify that it is still collocated in the local vicinity of the wireless audio access point, such as being in the same room. The wireless audio access point is capable of maintaining a connection with additional portable wireless devices, such as a student microphone (40).
