RF Architecture – A new technology to increase spectral purity that will contribute to an increase in transmission speeds in 5G

Company Overview

RF Architecture is a new firm, founded in June, 2016, which has developed a new, patent-pending technology to clean up the sine wave spectrum, which is the base of all wireless communication. Telecommunication transmissions through clean spectrum can bring down the rate of bit errors while increasing efficient transmission speeds. RF Architecture business model is to license this technology to 5G chip vendors, thereby contributing to the spread of 5G.

Reasons for joining the 5GMF

RF Architecture was only recently founded and was unsure where to find firms working on 5G. But in order to contribute to the spread of 5G, we feel it is necessary to participate in future discussions on standards. Many different maker firms participate in meetings at the 5GMF. Since we believe it is important to be involved from the beginning of these discussions in order to have our technology adopted, we think the 5GMF is the place where we can actively build our network.

Activities related to 5G

The technology developed by RF Architecture is able to produce a clean sine wave transmitted wirelessly from base stations. Until now, as the frequency increases “the spectrum purity”, or the phase noise of the sine wave, has degraded with the use of a common type of semiconductor, Voltage Controlled Oscillators (VCO). At the higher frequency bands, fluctuation of oscillation causes an increase in bit errors and limits the increase in data speeds.

RF Architecture’s new technology, however, will keep spectrum purity degradation at a minimum at even the highest frequencies by using surface acoustic wave (SAW) oscillators. The technology enabling a stable saw oscillator had been difficult to stabilize, but now spectrum purity can be ensured in high frequency sine waves. Use of RF Architecture’s new technology can ensure a spectrum purity of up to 1000 times more than now.

Comparison between conventional VCO oscillator and our new oscillator

Currently, the rate of bit errors has been too high so potential modulation methods for high speed transmissions (such as 256 QAM) have had needed to been replaced with modulation methods for lower speeds with higher stability (such as 16QAM). With the use of RF Architecture’s technology, with a high spectral purity and the rate of bit errors is lowered and controlled, data transmissions can use modulation methods that are able to facilitate high speed transmissions. This would result in an increased transmission capacity for 5G, as this technology will be able to be used in the proposed 5G transmissions bands, especially the 1GHz to 10GHz.

IoT Capabilities

This technology that will increase spectral purity can be used not only with downloading from base stations to devices but with uploading from devices to base stations, which is expected to allow for the increase in transmission speed and capacity. Since in the future IoT is expected to bring about a large increase in upstream transmission, this new technology to increase spectral purity will ensure the upload capacity in 5G systems overall.

Additionally, in RF Architecture’s technology also possesses the ability to down convert a signal even as weak and strong signals are received at the same time. Using this technology, IoT wireless transmissions, mostly at the 900MHz band, weak signals will be transmitted to long distance sensors while strong signals can be transmitted to nearby sensors at the same time. This will provide for a greater transmissions coverage area.

Message to current and future 5GMF members

RF Architecture wishes to discuss our new technology with 5GMF members who are hardware vendors, a membership category which is expected to increase in the future. Firms participating in 5GMF meetings can talk with each other regardless of the size of the firm, something that cannot happen outside the 5GMF. We hope even more firms join the 5GMF in the future to allow for more deep and meaningful discussions on the future path of 5G.
