Resonant Infographic Shows Path to 5G Networks Offering Bandwidth of More Than 700 Mbps

5G Performance Is Essential To Meet Streaming Video Needs; Resonant’s Shannon-Hartley Theorem Analysis Shows How 5G Can Deliver more than 700 Mbps

GOLETA, Calif., June 09, 2020 (GLOBE NEWSWIRE) -- Resonant Inc. (NASDAQ: RESN), a leader in transforming the way radio frequency, or RF, front-ends are being designed and delivered for mobile handset and wireless devices, today released a new infographic that details what is needed in a 5G “Wave 2” device to deliver mobile bandwidth of more than 700 Mbps.

Today’s 5G “Wave 1” network is non-standalone (built on top of an existing 4G network) and offers speeds of about 16 Mbps. When 3GHz and higher 5G frequencies are available, this performance can increase to over 30 Mbps, and can double again to more than 60 Mbps on mobile devices with multiple antennas.

This performance improvement is significant, but it’s not sustainable. As more users join the network, interference increases and this performance drops dramatically to just 19 Mbps. Overcoming this interference with a 5G radio frequency (RF) filter and 3GHz and higher 5G bandwidths can deliver throughput of over 700 Mbps – which is true 5G “Wave 2” performance.

“Early mobile users have pointed out the drawbacks to 5G “Wave 1,” but we’re believers in 5G technology and put together this infographic as a resource to show the importance of RF filters in reaching the maximum 5G throughput and the true promise of the technology,” said George Holmes, Chairman and CEO of Resonant. “5G has many use cases, but by far the most important is video and streaming media, which requires the maximum throughput.”

The infographic analysis utilizes the Shannon–Hartley theorem which predicts the maximum data rate over a communications channel. Inputs to the theorem include channel bandwidth (RF frequency), number of channels (multiple antennas) and signal reception quality.

The infographic also demonstrates the impact of interference on 5G “Wave 2” performance by measuring the download time for a 3GB movie file. With the expected  5G “Wave 1” network performance (19.2 Mbps), the movie file downloads in 20 minutes and 50 seconds. With a 5G “Wave 2” network connection (more than 700 Mbps), the same file downloads in just 34 seconds.

Resonant has developed its XBAR resonator technology to provide 5G “Wave 2” performance in mobile devices and wireless infrastructure. XBAR is critical to 5G “Wave 2,” delivering up to hundreds of megahertz of bandwidth, support for high radio frequencies, rejection of interfering signals and high power signal for increased coverage.
