What is the expected growth rate for Certus 200 in the full year 
 space that are sort of starting to mature. I think they are years away from implementation and no one's really committed to implementing them yet. So I think that's a longer-term trend that will happen in the industry that we obviously will keep track of and consider how we might evolve to it.
By the way, our underlying systems continue to sort of evolve to meet what I would call 5G or 3G PP kind of standards overall. In terms of the overall smartphones, obviously, I've responded to that in the last several earnings calls, told you that we believe that's a strong focus for us. You can tell in our results that we are ideally positioned for personal communications across a wide variety of areas, both stand-alone, and we believe long term in terms of supporting that in all kinds of consumer devices, including smartphones. I'm not really prepared to talk any further about sort of detailed plans on that until we're able to give plans, but we have been working on it for quite a while.

Landon Park -- Morgan Stanley -- Analyst
Great. Thank you. And I was wondering if you could update us on the broadband side and just how you think the cadence is going to look for the full year? And maybe on the Certus 100 side, are there any particular new products that you see coming that are particularly exciting from your standpoint?
Matt Desch -- Director and Chief Executive Officer
OK. Well, broadband continues to, I think, pace our expectations here as we continue to have more products from our partners that we're able to meet more market segments like moving beyond maritime and land into aviation and government as we move down from the original sort of Certus 700 products to Certus 200 and Certus 100, we continue to see growing activations, growing adoption. I think I think we're kind of becoming the de facto L-band standard for anything non-Inmarsat in the industry, which are all the VSAT players that do not make up the sort of ViaSat Inmarsat continuum, continuing to kind of be able to be more and more cost effective to go from the larger ships to smaller ships or from commercial aircraft to general aviation and UAV. So I would say -- I'd expect continued kind of quarter-over-quarter growth, particularly as we progress through the year and into the bigger parts of the summer, and that continues to be a strong market for us.
It's obviously growing at double-digit rates, and we expect that will happen for a long period of time. As far as Certus 100 goes, you have the portfolios of products that our partners are putting together continue to expand. We're seeing initial activations and across a wide variety of areas from drones to devices on chips to systems on aircraft and land mobile applications. We're going to see, I think, more IoT services coming about.
I'd say ones I'm particularly excited about, I'm excited about all of them. I think you're going to start sort of seeing that product hit the consumer segment this year and next year where anybody can sort of buy a product that could work say on the clear sheet of a small airplane or on a boat or on -- it can be portable devices, moving from sort of power devices into the portable range. So yes, I'm very bullish on what Certus 100 will kind of do to us long term. It's really a sweet spot for us.
Landon Park -- Morgan Stanley -- Analyst
Great. And just one clarification on the SG&A guidance. So should we be looking at about $120 million for the full year? Is that the right number?
Tom Fitzpatrick -- Chief Financial Officer
Well, we said it would be about 20%. So --

OK. OK. Thanks very much.
