The way I look at this is, as I said, last five years, as we introduced new advanced breakthrough technologies, so the very clear life cycle. It takes good four to five, six months of POCs, because customers want to deploy, they want to test it out, they want to keep the buyers. So what we will see I think is that in Q3, and maybe some Q4 we last of POCs. These POCs are seeds in the ground, and then they start to accelerate customers and how to deployed, and if there's any, issues in some software installations or RF characteristics, they learn all that. So my sense is you will see some explanation for Wi-Fi 6 and probably 60 gigahertz and give up a lot of good strong exhibitions probably will come in '21. And as I said earlier, these technologies are deployed over two, three year periods. They're not just one or two quarters. And we have very good experience with our Medusa, which was Massive MUMIMO breakthrough technology or our Wi-Fi product lines. So my sense is that I think this will be, this is not a massive hockey stick suddenly and then it's going to be a nice ramp, which will go in '21, '22 and maybe '23 just start to decline, just forget a cycle you see. Let me address one more question you asked. In terms of -- these are very efficient technologies. So if not that suddenly the network will become very large with them, I think what you will see is they will coexist with the previous products. They will find new applications where we are not there. For example, when it comes to urban connectivity, Cambium really doesn't do much urban connectivity, but I think the 60 gigahertz could potentially open urban backhauling application for us, so small cell backhauling. So I think we will see lots more applications of this in Tier 2, Tier 3 service providers, large service providers might experiment, but generally, I would say Tier 2, Tier 3, the faster adopters of advanced technologies. That's kind of what I see in event '21.
