Which is the wireless LAN technology that connects devices in a small area.
Bluetooth is the wireless LAN technology that connects devices in a small area.
Bluetooth uses FHSS technology in the ISM band of 2.4 to 2.485 GHz to connect devices such as keyboards, pointing devices, audio headsets, printers, PDAs, and cell phones.
In another usage, a personal area network (PAN) is a technology that could enable wearable computer devices to communicate with other nearby computers and exchange digital information using the electrical conductivity of the human body as a data network.
The main difference is that Bluetooth is primarily used to connect devices without using cables, while Wi-Fi provides high-speed access to the internet. Bluetooth is a wireless technology standard that is used to exchange data over short distances (less than 30 feet), usually between personal mobile devices.
A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.
