Abstract: Systems and methods are provided for operating an intercom system using a wireless access point. A codec is selected (501) from a plurality of available codecs. In some implementations, the available codecs present a tradeoff between audio quality and intercom device capacity. The access point operates (505) using the selected codec and, in response to detecting a new intercom device connecting to the intercom system (507) through the access point, the access point transmits a signal to the new intercom device identifying the selected codec. In response to a determination that the new intercom device does not have the selected codec stored in its memory, the access point automatically uploads (515) the codec to the new intercom device and transmits communications with the intercom device—including, for example, audio stream data—using the selected codec.

Abstract: A wireless communication system including a transmitter and a receiver. The transmitter includes a first mixing module, a phase-locked loop module, reference oscillator, and a second mixing module. The first mixing module is configured to combine a low-frequency data signal and an audio signal, and to generate a first combined signal. The phase-locked loop module is configured to generate a phase error signal based on a reference signal and a frequency modulated signal. The reference oscillator generates the reference signal having a frequency based on the low-frequency data signal. The second mixing module is configured to combine the first combined signal and the phase error signal, and to generate a second combined signal. The transmitter generates the frequency modulated signal based on the second combined signal and transmits the frequency modulated signal. The receiver is configured to receive the frequency modulated signal, and extract the low-frequency data signal and the audio signal.
