What is the estimated latency of real 5G networks 
 ultrawideband, and potentially even Millimeter Wave. Driven by this market recognition and potential, we expect 2021 to be the breakout year for our XBAR technology. Turning to Slide 4.
There's a ton of excitement in the media around the promises of 5G, and understandably so as it will affect every industry and broadly improve many parts of our day-to-day lives. However, I'd like to spend some time clarifying where we are and where we are headed as it relates to the rollout of 5G, as well as the ultrafast next-generation networks such as Wi-Fi and ultrawideband, which are often dependent upon each other and are critical to the connected world we all envision in the future. The improvements in speed and latency with their foundation in power handling at high frequency and wide bandwidth, the next-generation networks require to open the door to massive connectivity between people and things are taking shape on a broader scale. Mobile phones, smart devices, home appliances, connected vehicles, and many more applications are poised to benefit from this real-time communication.
And all of the networks powering these applications need RF filter solutions such as the ones Resonant's XBAR technology enables. While the network operators are working hard to deliver nationwide 5G coverage in its initial form, bringing the very early stages in its performance and capability, we are essentially rounding first base with today's 5G as it's only available in relatively few cities across a limited number of expensive devices that exhibit less than marketed performance. The revolutionary improvements that 5G networks will provide is not yet available. Real 5G data speeds will be 100 times faster than 4G with -- with latency 25 times that of 4G, and this will only be achievable with protection against interference.
In January, U.S. mobile network operators spent over $80 billion to acquire new Sub-6 gigahertz RF spectrum, upon which their 5G network services will be built, a new record. This is another indication of our forecast that the second wave of 5G deployment will be in the Sub-6 gigahertz range and it won't be until 5G's third wave for full Millimeter Wave deployment. What this means is in the absence of XBAR technologies being deployed, the market would leverage aluminum nitride BAW, which has shorter range, requiring more base stations to be deployed in the operators' networks, which equals higher cost.
We believe there is a potential for billions of dollars of spectrum that could be wasted in the U.S. alone due to interference degrading spectral efficiency or based on the increased number of base stations to deliver the same coverage. 5G will also depend on next-generation networks such as Wi-Fi 6E and ultrawideband, which bring additional capacity and speed, as well as extreme location accuracy. These new networks serve as a backstop to the 5G cellular network, which can easily reach capacity and become overloaded.
Turning Slide 5. The challenge that exists with these networks is unlike any other in the history of wireless technology. Delivering state of performance to these next-generation networks requires every device to have high-performance RF filters. It's well-documented that the RF filters that were designed for 4G requirements are not technically well-suited and cannot scale to meet the demands of these next-generation networks due to the physics behind the base technology not having the required power handling and bandwidth at high frequencies.
But let's take a few minutes to explore what would happen in a world where Resonant's XBAR technology did not exist. The handset OEMs are going to demand that the market's leading providers of RF filters deliver the best solutions they can that can support the standards of 5G operation. Remember, 98% of the RF filter market is controlled by seven companies. Turning to Slide 6.
Without XBAR, those legacy filter technologies will be adapted to deliver the best solutions available, pushing the boundaries of their existing performance by adding external components or creating modu
