5G stands for fifth generation wireless technology. It is the latest iteration of cellular technology that has three
main features:
- Greater speed
- Lower latency
- The ability to connect a lot more devices simultaneously.
A commercials 5G wireless network is expected to be deployed by 2020.This paper provides a brief introduction to 5G wireless technology.
5G Wireless Technology
Wireless communication technology has grown and advanced significantly over the years through research and innovation. The time has come when we can connect various wireless technologies, networks, and applications simultaneously. This latest technology is called 5G. The fifth generation wireless system (or 5G for short) is now the next generation of wireless communication systems.
It is the next major phase of mobile telecommunications standards beyond the current 4G. 5G moves us beyond
networks design for mobile devices alone toward systems that connect different types of devices operating at high speeds.
The key features of 5G include
- improved spectrum efficiency
- reduced latency
- better mobility support
- high connection density.
It supports interactive multimedia, voice, video, Internet, and other broadband services. To support increased throughput requirements of 5G, new spectrum has been assigned to 5G in mmWave bands. 5G will use Multiple Input Multiple Output (MIMO) to significantly increase network capacity [1].The move to 5G wireless communication standard is an action in response to the growth of the Internet of Things and the rise in demand for access to video and services over wireless broadband [2]. Although 5G is not expected until 2020, an increasing number of companies are investing now and are creating 5G products. Development of the new mobile wireless standard is being led by companies such as Intel, Qualcomm, Nokia, Ericsson, BT, Verizon, AT&T, and Samsung.
