5th generation mobile networks or 5th generation wireless systems is abbreviated as 5G, and proposed next telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G planning aims at higher capacity than current 4G, allowing a higher density of mobile broadband users, and supporting device-to-device, ultra reliable, and massive machine communications. It’s research and development also aims at lower latency than 4G equipment and lower battery consumption, for better implementation of the Internet of things.
