WDM-PON bearer 5G application scenarios and technology research
1. WDM-PON bears 5G application scenarios 1.1 Pre-transmission network architecture definition With the rapid development of mobile Internet and the emergence of a variety of new applications such as the Internet of Things, in order to cope with the future explosive mobile data traffic growth and massive device connectivity, the fifth generation of mobile communication (5G) technology came into being. In 2015, ITU-R officially defined three typical application scenarios for 5G: eMBB, mMTC and URLLC. eMBB corresponds to large-capacity mobile broadband services such as 3D/Ultra HD video. mMTC corresponds to large-scale Internet of Things services, while URLLC corresponds to services such as driverless, industrial automation, etc. that require low latency and high reliability. On November 28, 2016, China Mobile released a white paper on the 5G C-RAN requirements, architecture and challenges.
