Resonant – a company specializing in RF filter designs for difficult bands, modules, and other complex RFFE requirements – has released a new infographic (opens in new tab) illustrating what it believes is needed in a 5G “Wave 2” device to deliver mobile bandwidth of more than 700 Mbps.
According to Resonant, today’s 5G “Wave 1” network is non-standalone, and is built on top of an existing 4G network, providing speeds of about 16 Mbps. And when 3GHz and higher 5G frequencies are available, this performance can increase to over 30 Mbps (doubled with multiple antennas).
However, this performance isn’t sustainable within existing 5G networks, and the noise interference present. And as more users join the network, Resonant says, interference increases further, and this performance drops dramatically. And its eradicating this filter interference that Resonant says will take us to the next stage of 5G, or “Wave 2” as it calls it.
“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.”(opens in new tab)
The infographic takes its lead from the Shannon–Hartley theorem, which predicts the maximum data rate over a communications channel. And it demonstrates the impact of interference on 5G “Wave 2” performance by measuring the download time for a 3GB movie file.
With interference the file took over 20 minutes to download, but on a 5G “Wave 2” network connection (more than 700 Mbps), the same file downloaded in just 34 seconds.
