The Case for Boosting Mobile Application QoE via Smart Band Switching in 5G/xG Networks

5G and future 6G networks support diverse combinations of access technologies, architectures, and radio frequencies, with each combination termed as a "band" henceforth. Through comprehensive measurements in 12 cities across 5 countries, we …

Vivisecting Mobility Management in 5G Cellular Networks

With 5G's support for diverse radio bands and different deployment modes, e.g. standalone (SA) vs. non-standalone (NSA), mobility management - especially the handover process - becomes far more complex. Measurement studies have shown that frequent …

A Variegated Look at 5G in the Wild: Performance, Power, and QoE Implications

Motivated by rapidly expanding deployment of 5G services, we carry out an in-depth study to understand how 5G impacts application performance and energy efficiency. We examine the effects of 5G deployment strategies such as Non-Standalone (NSA) 5G …

About 5G NR in General

5G has already been deployed in so-called Non-Standalone Deployment (NSA). Vendors such as Verizon, AT&T and T-Mobile adapt the novel milimeter Wave (mmWave) technology to provide extremely high bandwidth and low latency through the celluar network.
