The Way to 1 Gbps on Smartphones
One might inquire, “Aren’t current 5G speeds fast enough?”
It's a valid question!
1 Gbps opens up lots of possibilities. You can stream high-resolution videos and games, get large files in a flash, and even use virtual reality technology - that's something you just can't do with slower speeds. So if you're looking for an upgrade, 1 Gbps is definitely the way to go!
In a March 2020 report, Cisco predicted that average 5G mobile network connection speed will reach 575 Mbps by 2023. However, many are questioning whether 5G is really much better than 4G LTE. A headline in a January 2023 edition of The Wall Street Journal summed it up:
“It's Not Just You: 5G Is a Big Letdown.”
At TransSiP, We are Making Waves in the 5G Ecosystem.
Rakon has established itself as a world-leading provider of the must-have component for all technology - oscillators used in reference clocks. As the 5G frequency spectrums become increasingly extensive, Rakon met this challenge by creating an exceptionally low noise oscillator to meet the heightened 5G phase noise requirement that is unparalleled globally.
However, Rakon discovered there is a fundamental problem that limits the performance of 5G systems in real-world settings - the quality of the power supplies.
Creating a high-grade power supply for 5G technology is no small feat due to its expense. When Rakon and other vendors test their oscillators or 5G chipsets in the lab, they need equipment capable of providing a DC bias with adequately low level of noise. It typically worths more than US$2,000 - if not hundreds of thousands of US dollars as provided by the Keysight E5052B - something not achievable by handset and base station makers outside the laboratory setting.
According to Ookla, during Q4 of 2022, the overall median 5G mobile download speeds among the most popular devices in the U.S. was 134.63 Mbps – a far cry from 1 Gbps.
With the TransSiP's Harmony PI Filter, despite using a noisy power supply, we were able to achieve an impressive improvement in phase noise of the 5G reference clock to 6 times! This translates to a significant increase in the signal-to-noise (SNR) ratio of the RF ADC inside a 5G transceiver to 15dB!
This suggests that even the most economical power supplies commonly used in the real world can be transformed into high-quality, low-noise power supplies.
At present, we are working with a 5G lab and another national institute to see what other results we can get at the system level!
TransSiP and Rakon jointly experimented on a possible circuit topology.
The initial results are very promising.
Something is amiss here, with speeds falling far short of their projected marks.
