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

2013年至2014年间，全球移动数据流量增长了69%，到2014年底达到每月2.5艾字节（eb）。2000年至2014年间，全球互联网流量增长了2900%。2014年，全球新增了近5亿移动设备和连接，其中包括4.39亿智能手机。到2018年，100亿移动连接将产生超过15eb的流量[思科]。云计算、智能电网、医疗保健、物流、自动化、Netflix等诸多因素也推动了流量的大幅增长。此外，目前的人与人（H2H）连接将被物联网（IoT）和机器对机器（M2M）所补充，到2020年，需要无线连接的在线设备将超过500亿台。H2H和M2M的共存带来了额外的和多样化的需求。

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.
