Report: New circuit design could double cellular and Wi-Fi bandwidth

A group of engineers at the University of Texas in Austin is claiming to have solved one of the most significant limitations on cellular broadband performance. Both Wi-Fi and LTE radios are limited to either sending or receiving data within a given span of time, a fundamental limit in traditional RF technology.

The engineers are relying on the creative use of a circulator, a device that's used to transmit a radio signal through a series of ports and to ensure that signals transmitted through one port exit only through a second port: Port 1 always comes out of Port 2, Port 2 always links to Port 3, and so on. "The University of Texas team claims that by using a solid-state circulator (without a typical magnetic field) it can isolate transmission and reception loops," according to ExtremeTech.
