NTT is forecasting a global network load of 40 zettabytes by 2020 driven by a nation wide migration to ultra high-definition video (4K/8K), multi-angle viewing and multiple devices per person.
The shift from hardware-intensive to software-defined network control will also be seen in the wireless domain. NTT foresees Wi-Fi frequency interference evasion by using dynamic cell-based software controls. This will create cooperative WLANs. Data transmission efficiency will also be addressed by better, next-gen, high-compression technology (HEVC) and better multicasting.
