The Physics of Wi-Fi: Invisible Waves That Connect Us

  1. Wi-Fi uses radio waves to send data wirelessly between devices.
  2. These waves fall in the microwave range of the electromagnetic spectrum.
  3. Routers convert digital information into radio signals for transmission.
  4. Your device’s antenna picks up the signals and decodes them back into data.
  5. Wi-Fi commonly operates at 2.4 GHz and 5 GHz frequencies.
  6. Higher frequencies allow faster speeds but shorter range.
  7. Interference from walls or other devices can weaken Wi-Fi signals.
  8. Encryption protocols like WPA2 secure data traveling through the air.
  9. Wi-Fi standards (like Wi-Fi 6) boost speed, reliability, and efficiency.
  10. Physics of waves makes it possible to stream, work, and connect wirelessly.
