In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention. All radio access technologies have to solve the same problems: to divide the finite RF spectrum among multiple users as efficiently as possible. GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM.
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 ...
LTE Advanced signal indicator in Android LTE Advanced signal indicator on Xiaomi phones LTE Advanced signal indicator (4G+) on Samsung Galaxy phones in Europe. LTE Advanced (LTE+, LTE-A; [1] on Samsung Galaxy and Xiaomi phones — 4G+) is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard.
It is one of the two mobile data transmission technologies of the Long-Term Evolution (LTE) technology standard, the other being Long-Term Evolution Frequency-Division Duplex (LTE-FDD). While some companies refer to LTE-TDD as "TD-LTE" for familiarity with TD-SCDMA, there is no reference to that abbreviation anywhere in the 3GPP specifications.
3.5G is a grouping of disparate mobile telephony and data technologies designed to provide better performance than 3G systems, as an interim step towards the deployment of full 4G capability. The technology includes: High-Speed Downlink Packet Access; Evolved HSPA
5G succeeds 4G LTE wireless technology. Developments have been focused on enabling low-latency communications, and promises of a minimum peak network speed of 20 gigabits per/second (20 times faster than the equivalent on 4G LTE networks), and uses within Internet of things and smart city technology.
5G Broadcast (5GB), officially known as LTE-based 5G Terrestrial Broadcast, is a system for the distribution of television and other media content via terrestrial broadcasting networks. [ 1 ] 5G Broadcast focuses mainly on mobile use cases like smartphones and in-car radio.
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 ...
