'''4G''' refers to the fourth-generation of [[cellular network]] technology, first introduced in the late 2000s and early 2010s. Compared to preceding third-generation ([[3G]]) technologies, 4G has been designed to support [[all-IP]] communications and [[Mobile broadband|broadband]] services, and eliminates [[circuit switching]] in voice telephony.<ref name=":2" /> It also has considerably higher data bandwidth compared to 3G, enabling a variety of data-intensive applications<ref>{{Citation |last1=Li |first1=Zhengmao |title=From 5G to 5G+ |date=2020-08-11 |work=5G+ |pages=19–33 |url=http://dx.doi.org/10.1007/978-981-15-6819-0_3 |access-date=2022-08-03 |place=Singapore |publisher=Springer Singapore |doi=10.1007/978-981-15-6819-0_3 |isbn=978-981-15-6818-3 |s2cid=225014477 |last2=Wang |first2=Xiaoyun |last3=Zhang |first3=Tongxu|url-access=subscription }}</ref> such as [[HDTV|high-definition]] [[Streaming media|media streaming]] and the expansion of [[Internet of things|Internet of Things]] (IoT) applications.<ref name=":2" />

The earliest deployed technologies marketed as "4G" were [[LTE (telecommunication)|Long Term Evolution]] (LTE), developed by the [[3GPP]] group, and [[WiMAX|Mobile Worldwide Interoperability for Microwave Access]] (Mobile WiMAX), based on [[IEEE]] specifications.<ref>{{Cite web |last=Eberle |first=Dieter |title=LTE vs. WiMAX 4th generation telecommunication networks |url=https://3g4g.co.uk/Lte/LTE_WiMAX_WP_1101_BIT.pdf |website=3g4g.co.uk}}</ref><ref>{{Cite web |title=LTE vs WiMAX |url=https://www.networkworld.com/article/730980/wireless-lte-vs-wimax-2.html |access-date=2025-02-26 |website=Network World |language=en}}</ref> These provided significant enhancements over previous 3G and [[2G]].
