What is the expected contribution of the 5G market to the global economy over the next decade? 
ur XBAR technology. Our solutions were developed to be the best in the industry and now more than ever, this is quickly being recognized by the market and by the major players within the ecosystem.
But as we look at the competitive landscape for addressing the requirements of 5G, 6G mobile, Wi-Fi, 5, 6, and 7, ultrawideband and potentially millimeter wave, we believe our export-based solutions will be the best solutions to unlock the true potential for these next-generation wireless networks. Turning to Slide 4. Those who have been closely following the industry know, we are in the very early days of 5G when it comes to performance. With the 5G market expected to contribute roughly $7.6 trillion to the global economy over the next decade, it's easy to understand why the investment going into the space on the front end continues to ramp up.
In January, mobile network operators in the U.S. spent over $80 billion to acquire new sub-6 gigahertz RF spectrum on which the next generation of 5G network services will be built. This was a momentous step in the advancement of 5G network deployments, and this validates the national infrastructure of next-generation mobile networks is still in development. But what does it tell us about today's 5G? In this current form, true 5G has yet to expand into many cities and in few locations where there is 5G coverage that exhibits subpar performance.
In order for networks to reach the high data speeds of true 5G, there are several critical items that need to occur and considerations the market needs to address. I've talked a lot about the potential of Resonant's XBAR technology. But let me spend a few minutes discussing what this would look like in a world without XBAR-based filters. The newly acquired sub-6 gigahertz RF spectrum I just mentioned, is a strong indication that the next wave of 5G deployment will be in the sub-six gigahertz range.
Without XBAR, 5G networks would likely utilize today's aluminum nitride BAW RF filters, which were developed specifically for 4G. Due to their limited high-frequency RF performance, these legacy filters would require many more base stations deployed across the network to deliver the same coverage and consumer experience. Rolling out these additional base stations would be possible, but it's an incredibly more costly approach to achieve true 5G performance. Further, the spectrum wasted due to interference degrading spectral efficiency would be massive.
The inefficiency impact would be in the billions of dollars, and that is in just the U.S. Turning to Slide 5. Let me continue under the premise of a world where XBAR does not exist. There is clearly the potential for massive spectral efficiency issues driven by the challenges associated with using RF filters designed with technology developed for 4G on these next-generation networks.
Legacy BAW Filter technology inherently does not have the required power handling or bandwidth at high frequencies, causing devices such as handsets and routers that utilize these filters to suffer with degraded connectivity and performance. Now let's compare mobile devices, leveraging legacy filter technology against devices with Resonant's state-of-the-art XBAR technology. You will see that the difference in performance is substantial. The delay in mobile download times is just an example of the differences between using legacy filter technologies versus Resonant's XBAR technology.
In the modern environment, where smart devices, home appliances, connected vehicles, healthcare, and many more applications will rely on optimal speed and low latency. We believe our XBAR technology will be fundamental in meeting the connectivity requirements and performance expected by consumers to these next-generation networks. Turning to Slide 6. When we discuss the benefits of XBAR when compared to legacy filter technology, the differences in performance are measurable and can be demonstrated.
Let's dive into the exact challenges that existing BAW technologies have when it comes to meeting the bandwidth requirements of next-generation netwo
