New OneAdvisor-800 Application Note: 4G/5G Signal Analysis

Published: 19th April 2021

VIAVI OneAdvisor is the ideal field test solution for 4G & 5G radio access networks, performing a comprehensive tests suite for an effective maintenance and optimization of the radio access network.

The radio access characteristics of 4G-LTE and 5GNR technologies have some commonalities and interdependencies that allow the industry, including mobile operators and network element manufacturers, to have a gradual migration and evolution based on different applications.

An important commonality is the signal format, both technologies use orthogonal frequency division multiple access (OFDMA) transmission structure, which maximize the spectrum resources by allocating resource elements based on frequency and time.

Having the same OFDMA signal structure created opportunities of inclusion of 5G-NR into a well-established 4G-LTE network, which is the case of Dynamic Spectrum Sharing (DSS) where conventional 4G-LTE channels can also transmit 5G-NR data sharing resource block in frequency and/or time. Similarly, is the case of initial 5G-NR deployments that needed dual connectivity or in non-standalone operation, establishing all the user equipment (UE) control signaling through a 4G-LTE channel and UE data traffic through a different 5G-NR channel.
