In fewer than 20 years, wireless networks will carry information at the speed of the human brain.

5G networks operate in frequency bands ranging from 600 MHz up to 6 GHz, called sub 6GHz, and also in the frequency bands from 24GHz to 100GHz, called millimeter wave. 5G provides up to 50X more speed, 1/10th the latency, and 1,000X more capacity than 4G. Additionally, Wi-Fi 6, delivers 4X times the capacity and 75 percent lower latency than Wi-Fi 5.

Dr. Ted Rappaport, professor at NYU Tandon School of Engineering and founding director of NYU Wireless, suggests that future terahertz frequencies will likely be the first wireless signals to provide real-time computations comparable to the speed of the human brain and capable of remote human cognition.

The Problem

High-frequency signals, which are used in 5G, 6G and Wi-Fi 6 lose significant signal strength going through physical barriers including glass, wood and concrete. This loss in signal strength results in lower data rates and generates latency resulting in significant performance degradation inside of buildings. Telecom carriers are working to ensure this doesn’t happen by investing and testing next-generation technologies that leverage existing infrastructure to propagate the signal.

To deliver on the promise of digital transformation of the enterprise and home, connectivity inside buildings must be solved.

The Solution

PHYTunes has developed a patent-pending breakthrough technology that can efficiently deliver multiplexed wireless spatial streams and control channels over common wireline infrastructure utilizing an intermediate frequency (IF) band. This effectively extends the range of wireless signals around the barriers that limit propagation of high-frequency signals, thereby enabling lower latency, higher efficiency, lower power consumption, and being environmentally friendly as a result.

PHYTunes understands the value proposition of a converged user experience and is working with leading service providers and private network builders around the world to enhance performance in the home and business. With wireless wireline convergence at the edge, we can bring the network closer to the customer, and solve the in-building connectivity problem thereby enabling the full potential of 5G and Wi-Fi.

Cellular Subscriber Lines (CSL), the invention of PHYTunes, is the technology innovation that addresses in-building signal coverage and delivery. As shown in the diagram below, CSL technology leverages existing wire-line infrastructure such as telephone lines, fiber-optic cables, ethernet wires, and coaxial to quickly and inexpensively extend the coverage of high-frequency signals including 5G and Wi-Fi, inside homes and buildings.
