According to Statista, there is a projected 30 billion Internet of Things (IoT) devices to be connected by 2020. That would be over a 400% increase in connected IoT devices from 2014. Most of these IoT devices will need to be connected through at least one type of wireless radio frequency (RF) communication.
With so much hype around 5G over the last few years, it’s understandable that business leaders would be skeptical of its promises. As Larry Downes points out in Harvard Business Review, the implications for 5G for businesses are so diffuse and novel that many business leaders have a hard time imagining them, much less putting financial trust in them. So, will 5G’s promises be fulfilled?
All signs point to yes, though it will probably take a few years. But don’t let that fool you into thinking there’s time to waste.
History shows us that when new technologies disrupt industry, it happens at lightning speed. The businesses most poised to benefit from the era of 5G are those that are laying the foundation by building and offering 5G solutions today.
Keep reading to learn what 5G is, where its future is headed, and why now is the time to invest in 5G infrastructure.
The Internet of Things (IoT) is a broad term which encompasses the multitude to wirelessly connected devices that surround us. It applies not only to smartphones and tablets, but to millions of machines, devices, and new twists on traditional products which were previously not connected to the internet. But what makes it all possible? How do these devices connect to the internet and communicate with each other?

In case you haven’t heard, Passive WiFi is an amazing innovation poised to revolutionize wireless communications, beginning with the internet of things (IoT) or industrial internet. It promises a future of WiFi communication that is 10,000 times more energy efficient.
Inside Frequency Control was able to get a back-stage pass to this exciting technology when we had a chat with one of the co-inventors, Shyam Gollakota. Check out the interview where we learned more about Passive Wi-Fi (you can read their research paper here) AND the process the researchers used to bring this innovation to life.
