What is Bluetooth and how does it work?
Bluetooth is a wireless personal area network technology that allows devices to communicate with each other over short distances, typically up to 30 feet. It uses radio waves to transmit data between devices, and operates on the 2.4 GHz frequency band. Bluetooth devices use a process called frequency hopping spread spectrum to minimize interference from other devices.
Bluetooth devices are categorized into three classes, each with a different range of operation. Class 1 devices have the longest range, up to 100 meters, while Class 3 devices have a shorter range of up to 1 meter. Bluetooth devices also have different power consumption profiles, with some devices using more power than others. This affects the battery life of devices that use Bluetooth.
What is WiFi and how does it work?
WiFi is a wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It uses radio waves to transmit data between devices, and operates on the 2.4 GHz and 5 GHz frequency bands. WiFi devices use a process called spread spectrum to minimize interference from other devices. WiFi networks use a device called a router to connect devices to the internet or to each other.
WiFi devices are categorized into different speed categories, such as 802.11ac, which is the latest and fastest WiFi standard.
