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 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
