4G connectivity in Australia
In telecommunications, 4G is the fourth generation of cell phone mobile communications standards. It is a successor to the third generation standards. A 4G system provides mobile "ultra-broadband" Internet access. Major Australian telecommunications companies, and most resellers that use one of these major telcos, have been rolling out and continuing to upgrade 4G since 2011/2012.
