5G Broadcast (5GB), officially known as LTE-based 5G Terrestrial Broadcast, is a system for the distribution of television and other broadcast media content via terrestrial radio broadcast networks based on downlink-only LTE technology. [1] [2] 5G Broadcast focuses mainly on mobile use cases like smartphones and in-car radio.
It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth generation) long-term evolution standard. The 3GPP specification 38 series [3] provides the technical details behind 5G NR, the successor of LTE. The study of 5G NR within 3GPP started in 2015, and the first specification was made available by the end of 2017.
LTE is also called 3.95G and has been marketed as 4G LTE and Advanced 4G; [citation needed] but the original version did not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced.
LTE's Enhanced Multimedia Broadcast Multicast Services (E-MBMS) provides transport features for sending the same content information to all the users in a cell or to a given set of users (subscribers) in a cell using a subset of the available radio resources with the remaining available to support transmissions towards a particular user (so-called unicast services).
The specification is referred to as Evolved Multimedia Broadcast Multicast Services (eMBMS) when transmissions are delivered through an LTE (Long Term Evolution) network. eMBMS is also known as LTE Broadcast. [1] Target applications include mobile TV and radio broadcasting, live streaming video services, as well as file delivery and emergency ...
LTE (Long Term Evolution) is commonly marketed as 4G LTE, but it did not initially meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. Given the competitive pressures of WiMAX and its evolution with Advanced new releases, it has become synonymous with 4G. It was first ...
The pre-4G 3GPP Long Term Evolution (LTE) technology is often branded "4G – LTE", but the first LTE release does not fully comply with the IMT-Advanced requirements. LTE has a theoretical net bit rate capacity of up to 100 Mbit/s in the downlink and 50 Mbit/s in the uplink if a 20 MHz channel is used — and more if multiple-input multiple ...

In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union under the IMT-2020 ...
