In summary, the conversation discusses the appearance of output waves in WiFi and Bluetooth in the time and frequency domains. The conversation also mentions using an oscilloscope and a spectrum analyzer to observe these waveforms. The conversation concludes with a decision to move the topic to an EE forum.

In what domain? In the time domain it looks like a blur during the packet transmissions. In the frequency domain it looks like multi-lobed frequency bands. Is this for a schoolwork assignment or general interest?

In that case, I'll move the thread to the EE forum to get more views.

@Benjamin_harsh -- Does my post above make sense? Have you used an oscilloscope to look at communication waveforms of any kind? Have you used a spectrum analyzer to look at RF communication bands? :smile:
 

FAQ: What does the RF waveform of wifi/bluetooth look like?

What is an RF waveform?

An RF waveform is a type of electromagnetic signal that is used to transmit information wirelessly. It is a type of radio frequency (RF) signal that carries data, such as audio or video, over the airwaves.

What does the RF waveform of wifi look like?

The RF waveform of wifi is a series of oscillating electromagnetic waves that have a specific frequency and amplitude. It is typically represented as a sine wave, with peaks and valleys that represent the strength of the signal at a given time.

How does the RF waveform of bluetooth differ from wifi?

The RF waveform of bluetooth is similar to wifi in that it is also a series of oscillating electromagnetic waves. However, the frequency and amplitude of bluetooth signals are different from wifi, as they operate in a different frequency range and have a lower power output.

Can the RF waveform of wifi/bluetooth be seen?

No, the RF waveform of wifi and bluetooth cannot be seen with the naked eye. They are electromagnetic signals that are invisible to the human eye. However, they can be measured and visualized using specialized equipment, such as an oscilloscope.

How is the RF waveform of wifi/bluetooth used in communication?

The RF waveform of wifi and bluetooth is used to transmit data wirelessly between devices. The information is encoded into the waveform and then decoded by the receiving device. This allows for wireless communication and connectivity between devices, such as laptops, smartphones, and smart home devices.
