2. Ubiquitous Network Definitions
Ubiquitous came from Latin word which means exist everywhere.
The word is popular in IT industry after Mark Weiser from Xerox Inc., Palo Alto, California propose the concept of ubiquitous computing in 1988.
ICT Convergence that can be access by anybody, in anywhere, anytime and by anydevice.
