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.

Live webinar on 27th Jan 2021: Voice over 5G – evolution, deployment, technology and testing aspects

Voice services have been reality since decades and the industry wants to continue their success story in wireless networks also with 5G. Find out the technology aspects behind incorporating voice services in 5G networks and outlines possible deployment scenarios. To achieve best user experience, we will also demonstrate how to test voice capabilities of 5G smartphones in different deployment scenarios by using the unique R&S®CMX500 radio communication tester and the R&S®CMsquares 5G test software solution from Rohde & Schwarz.
