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

AI Thread Summary
A wireless audio transmitter using the 2.4GHz band is being planned, with an audio codec for mic inputs and speaker outputs. The project involves interfacing the audio codec to a system-on-chip (SoC) with 2.4GHz transmission and reception capabilities via I2S and SPI protocols. There are concerns about the feasibility of this setup, particularly regarding audio interfacing and streaming. Additionally, it is important to note that wireless transmitters require FCC licensing and compliance with regulatory standards. Consulting with local amateur radio clubs is recommended for practical advice on legal and technical aspects of the project.

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.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
