It defines a small cell called Piconet which is a collection of devices connected in an ad-hoc fashion.

Integrated Access Points (APs) for data/voice.īluetooth topology is referred to as a scattered ad-hoc topology.

Bluetooth is inexpensive personal area ad-hoc network operating in unlicensed lands and owned by the user.īluetooth SIG involves three applications based scenario However, it has an embedded mechanism to assist the application. Compared with Wifi, Bluetooth has a reduced data rate.

OFDM (Orthogonal frequency division multiplexing) and QAM (Quadrature Amplitude Modulation)īluetooth is an open specification (universal) for short-range wireless voice and data communications. Inventors of Bluetooth are Ericsson, Nokia, IBM, Toshiba and Intel formed a Special Internet Group (SIG) to expand the concept and to develop a standard under IEEE 802.15 WPAN (Wireless Personal Area Network).īluetooth is the first widespread technology for a short-range ad-hoc network that is designed for combined voice and data application.

It provides support for a large number of users It is more complex and requires configuration of hardware and software. Wireless adapter on all the devices of the network and a wireless router.įairly simple to use and switching between devices is easier. Content: Bluetooth Vs Wifiīluetooth adapter on all the devices connecting with each other. Wifi provides high bandwidth as the speed of internet is an important factor. On the other hand, Wifi provides access to more number of users.īluetooth is used when speed is not our concern and low bandwidth is allocated to it. Another difference between Bluetooth and Wifi is that limited number of devices have provision to connect with other devices in Bluetooth.
