Wifi Sends Data Through the Air. Here's How.

WiFi seems invisible, but it works like traffic in a crowded city. Multiple devices like phones, laptops, and smart TVs constantly compete for the same airwaves. Most home networks operate on the 2.4 GHz and 5 GHz bands, which are strictly governed by IEEE 802.11 standards. While a single modern router can manage dozens of connections at once, physical walls, distance, and electronic interference will reshape and weaken every signal before it reaches its destination.
