Fi techniques to achieve Hi-Fi solutions. Here’s why: 1. If you use computer design tools, the tool starts to impact what you do. But if it’s your hand, some lead, some paper and you, then there are no rules. 2. You’re never going to get it right on the first try.

Add to them some 25 to 50 billion new connected Internet of Things devices such as wearables, sensors, connected house applications, cars, infrastructure, and manufacturing equipment. The current mobile infrastructure can’t support the coming needs for data
