Patents & Technologies
We have developed a strong portfolio of patents on innovative and essential technologies for 5G and 6G mobile networks. The list below are patents granted by USPTO. More are pending. Many of the USPTO granted patents have also been granted in Europe and China with the rest in process.
Our granted patents have broad claims that are essential to massive MIMO, overcoming the large power consumption in massive MIMO, intelligent network deployment to reduce cost and increase performance, RF transceivers, smart mmWave repeaters and CPEs, etc.
In addition to claims covering a broad range of standard-essential 5G technologies, our patents cover critical 6G technologies that are in development, including Integrated Access and Backhaul (IAB), Cell-Free Mobile Networks, and bringing AI and machine learning to the physical over-the-air channels.
