Less than three decades ago, connecting two computers required a physical cable. Networking meant drilling holes through walls, running Cat5 cables, and dealing with the constant frustration of loose connectors. Today, we take for granted the ability to stream 4K video from a laptop while wearing wireless headphones that receive audio from a smartphone in another room.

Bluetooth and Wi-Fi are distinct, complementary wireless technologies utilizing the 2.4 GHz spectrum, with Bluetooth acting as a low-power, short-range "cable replacement" for devices, while Wi-Fi provides a high-speed backbone for internet connectivity. While Bluetooth employs adaptive frequency hopping for low-power personal networks, Wi-Fi utilizes OFDM to prioritize high-speed, data-intensive tasks.
