Bluetooth

Bluetooth enables short-range wireless communication between devices. While crucial for mobile connectivity, its applications extend beyond just audio.

Key capabilities:

• Connects devices within ~30 feet range
• Enables data transfer between paired devices
• Supports multiple simultaneous connections
• Functions without internet connectivity

Common applications:

• Audio streaming to wireless headphones/speakers
• File sharing between nearby devices
• Connection to wearables and fitness trackers
• Smart home device control
• Car entertainment system integration

The rise of Bluetooth accessories, particularly wireless earbuds, has influenced hardware design—many smartphones now omit headphone jacks entirely in favor of wireless connectivity.
