By 2022, 28.5 billion fixed and mobile personal devices and connections will help drive global IP traffic to reach 4.7 zettabytes annually. To support this traffic, we see the following trends emerging:  Edge, fog and serverless computing will redefine cloud computing and increase the criticality of always-on connectivity; PoE will become a powering strategy for wider array of higher-wattage devices and IoT applications; single-pair Ethernet will emerge as cost-effective transport for power, connectivity and security to the billions of IoT edge devices; enterprises will continue network densification strategies to support evolving 200/400G backbones; and Wi-Fi 6 or 802.11ax will make their way into new installations.
