A piconet is a small Bluetooth network that connects mobile devices wirelessly over a short range of 10m radius, using ultra-high frequency (UHF) radio waves, to form a personal area network (PAN).A piconet can be formed by at most 8 stations, one of which is the master node and the ... Read More

A scatternet is a type of Bluetooth network that is formed by the interconnection between two or more individual Bluetooth networks, called piconets. The devices in the scattered should be Bluetooth enabled so that they can communicate wirelessly over a short range of within 10m radius using ultra-high frequency (UHF) ... Read More

Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. For example, a person is an object which has certain properties such as ... Read More

Orthogonal frequency division multiple access (OFDMA) is a multi-user version of digital data modulation scheme OFDM (orthogonal frequency division multiplexing). In OFDM, a single stream of data is divided into several separate sub-streams for transmission via multiple channels. OFDM uses the principle of frequency division multiplexing (FDM), where the available ... Read More
