What is the total number of 5G devices that are being released right now 
illimeter wave offerings from our customers for the past few years.
So we expect it to continue to grow. Again, we're on the front end of something that's going to play out over the next decade because of the progression in millimeter wave spectrum from 20 to 40 to 70 to 90 gigahertz. And then with 6G coming in with terahertz, so there is a big long-term road map that's playing out. Specific to your question on 5G, maybe I can offer a data point.
If you think of the certification being a critical parameter for 5G devices, about 150 devices are being certified right now. About 30% of them have millimeter wave in it. So, you know, that paints the picture, hopefully. And the total number of 5G devices right now that are being released is about 700.
So it sort of gives you maybe a framing on where we are. It's still very early days.

Your next question will come from Samik Chatterjee of J.P. Morgan. Please go ahead.
Joe Cardoso -- J.P. Morgan -- Analyst
Hi. Yes, this is Joe Cardoso on for Samik Chatterjee. I just wanted to follow up on the last question, particularly around the supply chain issues that have been impacting companies industrywide. I guess just a clarification on my part.
You know, in this quarter, did you see an impact from supply issues on your top line and margins? And if so, what was the impact -- can you quantify the impact? And then relative to the guidance, are you guys baking in any headwind, material headwinds on the top line, or margins? Thank you.
Ron Nersesian -- Chairman, President, and Chief Executive Officer
Hi, this is Ron. As you know, in the last quarter, we exceeded our revenue guidance. And you've seen our guide for the next quarter, very pleased with the performance and how we've been able to deliver the revenue despite what's going on in the world. Of course, we see some COVID manufacturing decreases in capacity, as well as some supply chain components shortages.
However, we planned ahead. We fought for those. And the most important part is that when you look at custom ICs, which have a very, very long lead time for many folks in the industry, we have an on-site fab that creates and produces all of our custom ICs. So that enables us to basically have complete control of that supply chain for the critical custom parts.
We're very confident in the guide that we have. But there's no doubt that we have built backlog and our order book is strong. So as the world situation unravels, we could increase revenue even more and more in the future.

Your next question will come from John Pitzer of Credit Suisse. Please go ahead.
John Pitzer -- Credit Suisse -- Analyst
Yeah, good afternoon, guys. Congratulations on a strong quarter. Ron, I'm just kind of curious, with the recent C-band auctions in the U.S. now behind us, can you help me better understand how that kind of impacts your view on your comms business as we go throughout the balance of this year? And as you do that, I'd be kind of curious as to the sort of geographic distribution specifically.
As you think about next quarter and beyond, how much more important is China? Or are you actually starting to see things percolate in the U.S. and beyond?
Satish Dhanasekaran -- Chief Operating Officer
Yeah, John, you know, it's a good question. With regard to the deployment scenarios globally, you know, as we all know, China started to lead the 5G deployments. And with the C-band auction coming in, the major announcements from the U.S. operator referencing a road map to deploy more 5G in the country, we view it as a positive.
We saw an uptick of our -- in our business in the U.S., specifically for capabilities in the C-band this quarter, and we view the funnel and pipeline to be strong there. But again, not to get too siloed on one spectrum, because at the end of the day, our customers are looking to test for creating devices and products that cater to the global marketplace. And right now, we have 9,000 different band combinations that our customers have to test for
illimeter wave offerings from our customers for the past few years.
