Fifth generation or 5G is the latest generation to succeed the 4G, 3G, and 2G systems of cellular mobile communications. 5G infrastructure consists of enhanced mobile broadband with reduced latency and targets data rate, cost-reduction, energy saving, and higher system capacity. It is likely to witness better spectrum management, data segregation, and routing. 5G infrastructure would promote enhanced content delivery, assisted driving & transportation services, and remote healthcare & medical intervention. In addition to faster means of communication, 5G would significantly benefit those working into robotics, industry-automation, and IoT.
