Wireless is the transfer of information between two or more points that are not physically connected. Distances can be short, such as a few metres for television remote control, or as far as thousands or even millions of kilometres for deep-space radio communications. It encompasses various types of fixed, mobile, and portable , cellular telephone, (PDAs), and . Other examples of wireless technology include GPS units, or garage doors, wireless computer mice, keyboard and Headset, , , satellite televisi..
A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other Social relation between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures. ξ1 The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and ..
