Is a Wireless Audio Transmitter Feasible with 2.4GHz Band and an Audio Codec?

Click For Summary
SUMMARY

The discussion centers on the feasibility of building a wireless audio transmitter operating in the 2.4GHz band using an audio codec. The proposed design involves interfacing the audio codec with a System on Chip (SoC) that supports 2.4GHz transmission and reception. Key considerations include the audio codec's ability to handle microphone inputs and drive speakers, as well as compliance with FCC regulations regarding radio transmission. Engaging with local amateur radio clubs is recommended for practical advice and legal guidance.

PREREQUISITES
  • Understanding of audio codecs and their functionalities
  • Familiarity with System on Chip (SoC) architecture
  • Knowledge of I2S and SPI communication protocols
  • Awareness of FCC regulations regarding wireless transmission
NEXT STEPS
  • Research audio codec options compatible with I2S and SPI interfaces

Hi All,
we are planning to build a wireless audio transmitter. In 2.4GHz Band.
I would acknowledge that this is my first audio interfacing project.
So i have a lot of doubts about the way i can interface audio and stream the data out.
we plan to use an audio codec which can take Mic ( line in ) inputs and also should be able to drive a speaker ( let's consider the impedance later).
the audio codec will be interfaced to an SOC which has 2.4GHz TX/RX capability.
the idea is to interface the audio codec to the controller on I2S of Audio codec onto SPI of Controller(SOC).
Please throw some light on the feasibility.

Thanks,
Chandra

Radio transmitters need a license from the FCC. The FCC also sets the requirements for acceptable transmitters.

The most practical advice I can offer is to visit your local amateur radio club. Those HAMS are very knowledgeable, and could advise you on ways to do your project that are both feasible and legal.
