The new products will support both Non-Standalone (NSA) operation, where control signaling is sent over LTE, and Standalone (SA) operation, where all control signaling and user data are sent over 5G NR. This is line with a Qualcomm-backed industry proposal for a NSA-based intermediary 5G standard already in 2019. Qualcomm says it plans to have its chips ready for inclusion in commercial handsets and network launches in 2019.
The new members of the Snapdragon X50 5G modem family are designed to support multi-mode 2G/3G/4G/5G functionality in a single chip, providing simultaneous connectivity across both 4G and 5G networks. The single chip also supports integrated gigabit LTE capability.
