What is the current state of the 5G market in terms of install base and global demand?

Thanks. Good morning. Could you provide a little more detail on how you're reviewing the 5G opportunity? Just how large is that addressable market? And how quickly do you expect it to ramp?
Bob Patterson -- Chairman, President, and Chief Executive Officer
Yes. So I think it's going to -- well, first of all, for -- 5G is going to take place -- there's going to be a global pull for it. I would say that -- I probably talked about this on our last call and my recent visit to China where you can just see towers going up on every other corner and block. So they're going to be a leader in terms of getting out there and actually getting an install base.
I think that what you'll see is actually something that probably looks similar to how other generations have expanded. So even if you look at 4G right now or the predecessor technologies, they don't encompass the entire United States, if I pick the U.S., for example, right, there is still plenty of places that don't have access to the latest technology. So one of the things that I like most about 5G is that this is a multiyear growth opportunity for this business and for our segment. It's not something that's going to happen in one year.
And I really believe it will take place over the course of 12 or 15 years. But be a very solid and steady double-digit grower for us. So that's how to put that in perspective. Notwithstanding just kind of all the noise around Huawei and all that stuff that's going on right now.
Technology is going to move forward, right? And people are going to put this in if they perceive it's better. And so I don't see that changing as time moves on.

And regarding performance, products and solutions. How are you evaluating your strategic options for that business at this point in time?
Bob Patterson -- Chairman, President, and Chief Executive Officer
I don't think there is anything different to say about that with respect to how we think about our portfolio. So no new news.

And on that segment, would you say that second quarter represented just the catch up from maybe business that was lost due to weather in the first quarter? Or how sustainable are your second-quarter results in PP&S?
Bob Patterson -- Chairman, President, and Chief Executive Officer
Well, I mean I think there is certainly -- first of all, yes, you're right in pointing out that the first quarter was very difficult just in terms of how things started off with -- from a weather impact in the construction space. So I think there is some pick up. Year over year, I'd still say construction is down. And as a result of that you see the PP&S segment impacted by it.
But much better than what we saw in the first quarter. And I believe that's sustainable. So my sense is that if you just want to put things into perspective here for the balance of the year, you'll see some traditional seasonality with respect to Q3 and Q4. But I'm not expecting anything else beyond that.
So my view of where we're at is quite sustainable.

Hi, Kevin.
Kevin Hocevar -- Northcoast Research -- Analyst
Brad, cash flow is pretty strong in the quarter, and in particular, looks like working capital did -- you controlled that quite well. So wondering what drove that, and what type of cash generation do you think you can realize this year?
Brad Richardson -- Executive Vice President and Chief Financial Officer
Well, Kevin, as you know, I mean, we continue to have laser line-of-sight focus on our working capital. I think we're best in class in terms of our working capital as a percent of revenue and the organization clear
