It’s in our houses, connected to our phones, and our tablets. Sometimes it’s even in our cars, thermostats, and fridges, but does anyone really know how Wi-Fi works?

Welcome back to the 5G Guys podcast! Our guest today is Qualcomm’s Director of Technology Standards, Dr. Jim Lansford. Join us as he explains the history of Wi-Fi and how it’s become the worldwide standard for connecting billions of people around the globe. 

It’s easy to forget that Wi-Fi is its own separate entity in the wireless industry, especially when it comes to connecting with our everyday devices. Listen in as Dr. Jim breaks down just how Wi-Fi works and the common misconceptions you might have when it comes to routers, modems, ethernet, and more. 

Dr. Jim helps us understand how Wi-Fi works on the spectrum, what regulation looks like in this space, and why it’s free to use. You’ll learn the differences between cellular and Wi-Fi, especially when it comes to speed and creating a stronger signal. As well as the difference between cellular 5G and Wi-Fi 5G, how the whole world shares the same Wi-Fi spectrum, and the future enhancements they’re making to make Wi-Fi more reliable and available.
