5G spectrum

- [Male Instructor] I would like us to start by recapping … the different bands used in 5G and what are the trade-offs. … So just looking at this here, … you can see we have two rough regions. … One is the sub-six gigahertz, which is 3.5 gig … and below gig what we talked about. … And then we do have the millimeter wave. … Anything below six gigahertz is very congested. … It's prime spectrum because hardware's cheap, … the actual deployment is quite cheap. … But the problem is it's very congested. … It's very difficult to find a free band … of significant bandwidth, … which is available around the world. … So we're starting to move into the millimeter wave range … where you see so many more free bands available today. … So what is the challenge in 5G? … The challenge is to bring together so many philosophies, … so many different bands, … so many different ways of doing things … when it comes to spectrum. … So just let's have a look at the different bands. … Here are three bands I talked about. …
