An Android phone, showing that it is connected to a 5G network. 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 requirements, which outline performance targets for speed, latency, and ...
4G networks provide even higher bitrates and many architectural improvements, which are not necessarily visible to the consumer. The current 4G systems that are deployed widely are WIMAX and LTE. The two are pure packet based networks without traditional voice circuit capabilities. These networks provide voice services via VoIP or VoLTE.
Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e.g. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories. Networks on LTE band 20 (LTE-FDD) are suitable for roaming in ITU Region 1 only. Networks on LTE band 5 (LTE-FDD) are suitable for roaming in ITU Regions 2 and 3.
From the latest published version (Rel. 18) of the respective 3GPP technical standard (TS 38.101), [5] the following tables list the specified frequency bands and the channel bandwidths of the 5G NR standard. Note that the NR bands are defined with prefix of "n". When the NR band is overlapping with the 4G LTE band, they share the same band number.
