How does WiFi carry data between your device and the router?
Show answer & explanation
Answer: It encodes data into radio waves that the router and device exchange
It passes data through a nearby coil using magnetic induction — WiFi uses propagating radio waves, not a nearby coil's magnetic induction. Radio waves contain both electric and magnetic fields; the difference is how the signal travels, not whether magnetism exists.
It bounces signals off satellites orbiting above the Earth — Satellites are not needed for the local WiFi link between your device and router. A router might get its internet connection through a satellite service, but that is a separate link.
It encodes data into radio waves that the router and device exchange ✓ — WiFi encodes data in radio signals exchanged between a device and an access point, often built into a home router. The receiver decodes the signal back into data. Walls and distance can weaken reception.
