LTE Advanced Pro (LTE-A Pro, also known as 4.5G, 4.5G Pro, 4.9G, Pre-5G, 5G Project) [1] [2] [3] [4] is a name for 3GPP release 13 and 14. [5] [6] It is the next-generation cellular standard following LTE Advanced (LTE-A) and supports data rates in excess of 3 Gbit/s using 32-carrier aggregation. [7] It also introduces the concept of License Assisted Access, which allows sharing of licensed and unlicensed spectrum.

The 3rd Generation Partnership Project (3GPP) is a standards organization which develops protocols for mobile telephony. Its best known work is the development and maintenance of:

LTE Advanced

LTE Advanced is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project (3GPP) in March 2011 as 3GPP Release 10.

Carrier aggregation is a technique used in wireless communication to increase the data rate per user. Thereby multiple frequency blocks are assigned to the same user. The maximum possible data rate per user is increased the more frequency blocks are assigned to a user. The sum data rate of a cell is increased as well because of a better ressource utilization. In addition load balancing is possible with carrier aggregation.

Additionally, it incorporates several new technologies associated with 5G, such as 256-QAM, Massive MIMO, LTE-Unlicensed and LTE IoT, [8] [9] that allow evolution of existing networks into supporting the 5G standard. [10]

5G the latest generation of cellular mobile communications

5G is generally seen as the fifth generation cellular network technology that provides broadband access. The industry association 3GPP defines any system using "5G NR" software as "5G", a definition that came into general use by late 2018. Others may reserve the term for systems that meet the requirements of the ITU IMT-2020, which represents more nations. 3GPP will submit their 5G NR to the ITU. It follows 2G, 3G and 4G and their respective associated technologies.

Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme. The two carrier waves of the same frequency are out of phase with each other by 90°, a condition known as orthogonality and as quadrature. Being the same frequency, the modulated carriers add together, but can be coherently separated (demodulated) because of their orthogonality property. Another key property is that the modulations are low-frequency/low-bandwidth waveforms compared to the carrier frequency, which is known as the narrowband assumption.

MIMO Use of multiple antennas in radio

In radio, multiple-input and multiple-output, or MIMO, is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi), IEEE 802.11ac (Wi-Fi), HSPA+ (3G), WiMAX (4G), and Long Term Evolution. More recently, MIMO has been applied to power-line communication for 3-wire installations as part of ITU G.hn standard and HomePlug AV2 specification.

Voice over LTE Voice over LTE wireless network

Voice over Long-Term Evolution (VoLTE) is a standard for high-speed wireless communication for mobile phones and data terminals — including IoT devices and wearables. It is based on the IP Multimedia Subsystem (IMS) network, with specific profiles for control and media planes of voice service on LTE defined by GSMA in PRD IR.92. This approach results in the voice service being delivered as data flows within the LTE data bearer. This means that there is no dependency on the legacy circuit-switched voice network to be maintained. VoLTE has up to three times more voice and data capacity than 3G UMTS and up to six times more than 2G GSM. Furthermore, it frees up bandwidth because VoLTE’s packets headers are smaller than those of unoptimized VoIP/LTE.

LTE in unlicensed spectrum is a proposed extension of the Long-Term Evolution (LTE) wireless standard intended to allow cellular network operators to offload some of their data traffic by accessing the unlicensed 5 GHz frequency band. LTE-Unlicensed is a proposal, originally developed by Qualcomm, for the use of the 4G LTE radio communications technology in unlicensed spectrum, such as the 5 GHz band used by 802.11a and 802.11ac compliant Wi-Fi equipment. It would serve as an alternative to carrier-owned Wi-Fi hotspots. Currently, there are number of variants of LTE operation in the unlicensed band, namely LTE-U, License Assisted Access (LAA), and MulteFire.

MulteFire is an LTE-based technology that operates standalone in unlicensed and shared spectrum, including the global 5 GHz band. Based on 3GPP Release 13 and 14, MulteFire technology supports Listen-Before-Talk for fair co-existence with Wi-Fi and other technologies operating in the same spectrum. It supports private LTE and neutral host deployment models. Target vertical markets include industrial IoT, enterprise, cable, and various other vertical markets.
