Design, integration and analysis of wireless technologies for 5G networks

2013年至2014年，全球移动数据流量增长69%，2014年末达到每月2.5艾字节(EBS)。2000至2014年间，全球互联网流量增长了2900%。2014年增加了近5亿台移动设备和连接，其中包括4.39亿部智能手机。到2018年，100亿个移动连接产生的流量将超过15 EB[思科]。巨大的流量增长还受到云计算、智能电网、医疗保健、物流、自动化、Netflix等许多领域的推动。此外，目前的人与人(H2H)连接将得到物联网(IoT)和机器对机器(M2M)的补充，到2020年，物联网和机器对机器(M2M)将推出超过500亿台需要无线连接的在线设备。H_2H和M_2M的共存提出了额外和不同的要求。

Global mobile data traffic grew 69% between 2013 and 2014 and reached 2.5 exabytes (EBs) per month at the end of 2014. Global Internet traffic increased 2900% between 2000 and 2014. Almost 500 million mobile devices and connections were added in 2014, including 439 million smartphones. By 2018, 10 billion mobile connections will generate more than 15 EB of traffic [Cisco]. The massive traffic growth is also driven by cloud computing, smart grid, health care, logistics, automation, Netflix and many others. Moreover, current human-to-human (H2H) connections will be complemented by Internet of Things (IoT) and Machine-to Machine (M2M), which will introduce more than 50 billion online devices by 2020 that need wireless connections. The coexistence of H2H and M2M imposes additional and diverse requirements.
