LTE to 5G Evolution May 2025
LTE is a global success with over 6.6 billion subscriptions, connecting nearly two-thirds of mobile users worldwide. LTE is specified by 3GPP as a single global standard for paired and unpaired spectrum users. The vast majority of the standard is the same for frequency-division duplex and time-division duplex.
LTE has evolved through various 3GPP technology releases, covering the introduction of LTE-Advanced and then LTE-Advanced Pro, which significantly improved the capabilities of LTE networks. From 3GPP Release 15, the community has been defining 5G networks, starting with non-standalone 5G systems that integrate with existing LTE networks and moving onto standalone 5G systems with substantially different network configurations.
This report provides an independent, in-depth status update and analysis of the global 4G/LTE, LTE-Advanced and 5G markets. Information is obtained, analysed and verified by GSA.
