One of the biggest issues with cellular broadband performance is that WiFi and LTE radios can't send and receive information at the same time—but a hardware solution involving a circulator could offer a creative solution.
Experimentation from a group of engineers from the University of Texas reveals that the use of a solid-state circulator can isolate transmission and reception loops, making it easier for the signals to be picked up by the radio and create the ability for the system to be tuned in real-time. This hardware-based solution makes it so that the process of transmitting and receiving data does not interfere with one another. Considering the dependence on LTE and WiFi systems, this has the potential to be a huge breakthrough in radio frequency technology.
