4G is the fourth generation of broadband cellular network technology, succeeding 3G.  The International Telecommunication Union (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) = 12.5 megabytes per second), where coverage is possible and meets all specific 4G technological requirements.
