5th generation mobile networks or 5th generation wireless systems, abbreviated 5G, are the 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. 5G research and development also aims at lower latency than 4G equipment and lower battery consumption, for better implementation of the Internet of things. The Next Generation Mobile Networks Alliance defines the following requirements that a 5G standard should fulfill:
1) Data rates of tens of megabits per second for tens of thousands of users
2) Data rates of 100 megabits per second for metropolitan areas
3) 1 Gb per second simultaneously to many workers on the same office floor
4) Several hundreds of thousands of simultaneous connections for wireless sensors
5) Spectral efficiency significantly enhanced compared to 4G
6) Coverage improved
7) Signalling efficiency enhanced
8) Latency reduced significantly compared to LTE.[3][4]
In addition to providing simply faster speeds, they predict that 5G networks also will need to meet new use cases, such as the Internet of Things (internet connected devices), as well as broadcast-like services and lifeline communication in times of natural disaster. Carriers, chipmakers, OEMS and OSATs, such as Advanced Semiconductor Engineering (ASE) and Amkor Technology, Inc., have been preparing for this next-generation (5G) wireless standard, as mobile systems and base stations will require new and faster application processors, basebands and RF devices.
