What is Bluetooth and how does it work?
0:02
Definition. Bluetooth is a wireless
0:05
communication technology that allows
0:07
devices to exchange data over short
0:10
distances using radio waves and the 2.4
0:13
GHz frequency band. Explanation
0:16
Bluetooth replaces cables by enabling
0:19
devices like phones, laptops, speakers,
0:22
and headphones to connect wirelessly. It
0:25
uses low power radio signals making it
0:28
ideal for short range energy efficient
0:31
communication. How it works? One,
0:34
pairing to Bluetooth enabled devices
0:36
detect each other and create a secure
0:39
connection. Two, radio transmission.
0:42
Data is transmitted using microwave
0:45
radio waves to point for gigahertz band.
0:48
Three, frequency hopping. Bluetooth
0:51
constantly changes frequencies up to
0:53
1,600 times per second to avoid
0:57
interference from Wi-Fi or other signals
1:00
for low energy use. Uses minimal power,
1:04
making it suitable for portable gadgets
1:06
like earbuds and smart watches. Imagine.
1:09
Think of Bluetooth like an invisible
1:11
handshake between your phone and
1:14
headphones. Once paired, they share
1:16
information back and forth using radio
1:18
waves without needing wires. In simple
1:21
terms, Bluetooth is a wireless cable
