5G stands for 5 th generation wireless system. Current wireless standards are limited by the speed and bandwidth. 5G is a theoretical standard which will vastly improve upon current standard. 5G is also referred to as beyond 2020 mobile communications technologies. 5G does not describe any particular specification in any official document published by any telecommunication standardisation body.

It is a term used in some research papers and projects to denote the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards.

Although updated standards that define capabilities beyond those defined in the current 4G standards are under consideration, those new capabilities are still being grouped under the current 4G standards. Li-Fi, or light fidelity, is a 5th generation visible light communication network. Li-Fi uses light-emitting diodes to transmit data, rather than radio waves like Wi-Fi.

It offers the following features:


worldwide cellular phones


Extraordinary data capabilities


High connectivity


More power & features in hand held phones Large phone memory, more dialling speed, more clarity in audio and video


High resolution, bi-directional large bandwidth shaping.

Advanced billing interfaces: attractive and effective.

Subscriber supervision tools for fast action.

High quality services based on Policy to avoid error.

Large broadcasting of data (GB) supports almost 65,000 connections.

Transport class gateway with unparalleled consistency.

More accuracy by traffic statistics.

Remote management :better and fast solution

Remote diagnostics

25 Mbps connectivity speed.

Virtual private network.

All delivery service out of business prospect.

High uploading and downloading speed

Enhanced and available connectivity just about the world.

A new mobile generation has appeared approximately every 10th year since the first 1G system was introduced in 1981. The first 2G system started to roll out in 1992, the first 3G system first appeared in 2001 and 4G systems fully compliant with IMT Advanced were standardised in 2012. The development of the 2G (GSM) and 3G (IMT-2000 and UMTS) standards took about 10 years from the official start of the R&D projects, and development of 4G systems started in 2001 or 2002.

Predecessor technologies have occurred on the market a few years before the new mobile generation, for example the pre-3G system CdmaOne/IS95 in the US in 1995, and the pre-4G systems Mobile WiMAX in South-Korea 2006, and first release-LTE in Scandinavia 2009. Mobile generations typically refer to non –backwards-compatible cellular standards following requirements stated by ITU-R, such as IMT-2000 for 3G and IMT-Advanced for 4G. In parallel with the development of the ITU-R mobile generations, IEEE and other standardisation bodies also develop wireless communication technologies, often for higher data rates and higher frequencies but shorter transmission ranges.

Application Layer Presentation layer


Session Layer

Open Transport Protocol

Transport Layer Network Layer

Upper network layer

Lower network layer Datalink Layer

Physical Layer

Open Wireless Architecture


Physical Layer and Data Link Layer define the wireless technology. For these two layers the 5G mobile network is likely to be based on Open Wireless Architecture (OWA) OSI Layer1 + OSI Layer2 = OWA


 

All mobile networks will use Mobile IP and each mobile terminal will be Foreign Agent. A mobile can be attached to several mobile or wireless networks at the same time. The fixed IPv6 will be implemented in the mobile phone Separation of network layer into two sub-layers: Lower network layer (for each interface) and Upper network layer (for the mobile terminal)

The middleware between the Upper and Lower network layers maintain address translation from Upper network address (IPv6) to different Lower network IP addresses (IPv4 or IPv6), and vice versa.


Wireless network differs from wired network regarding the transport layer. In all TCP versions the assumption is that lost segments are due to network congestion. In wireless, the loss is due to higher bit error ratio in the radio interface 5G mobile terminals have transport layer that is possible to be downloaded and installed. Possibility to download (e.g., TCP, RTP etc. or new transport protocol) version which is targeted to a specific wireless technology installed at the base stations. Transport layer + Session layer = OTP


Provides intelligent Quality of Service management over variety of networks Provides possibility for service quality testing & storage of measurement information in information database in the mobile terminal Select the best wireless connection for given services Parameters, such as, delay, losses, BW, reliability, will be stored in DataBase of 5G mobile Presentation layer + Application layer = Application

5G Hardware: 

Uses UWB (Ultra Wide Band) networks with higher BW at low energy levels. BW is of 4000 Mbps, which is 400 times faster than today’s  wireless networks Uses smart antenna and CDMA (Code Division Multiple Access)

5G Software: 

5G will be single unified standard of different wireless networks, including LAN technologies, LAN/WAN, WWWW- World Wide Wireless Web, unified IP and seamless combination of broadband Software defined Radio, Encryption, Flexibility, and Anti-Virus.

Wearable devices with AI (Artificial Intelligence) capabilities

Pervasive (Global) networks

Media independent handover

Radio resource management

VoIP (Voice over IP) enabled devices with 6th sense technology

In 2008, the South Korean IT R&D program of "5G mobile communication systems based on beam-division multiple access and relays with group cooperation" was formed.

On 8 October 2012, the UK's University of Surrey secured £35M for new 5G research centre, joint funded between the British government's UK Research Partnership Investment Fund (UKRPIF) and a consortium of key international mobile operators and infrastructure providers –including Huawei, Samsung, Telefonica Europe, Fujitsu Laboratories Europe, Rohde & Schwarz, and Aircom International. It will offer testing facilities to mobile operators keen to develop a mobile standard that uses less energy and radio spectrum whilst delivering faster than current 4G speeds, with aspirations for the new technology to be ready within a decade.

On 1 January 2013, the ICT Labs project 5GrEEn (Towards Green 5G Mobile Networks) starts its activity under the EIT framework, and linked with the project carrier METIS.

On 12 May 2013, Samsung Electronics stated that they have developed the world's first "5G" system. The core technology has a maximum speed of tens of Gbps (gigabits per second). In testing, the transfer speeds for the “5G”  network sent data at 1.056 Gbit/s to a distance of up to 2 kilometres. In July 2013, India and Israel have agreed to work jointly on development of fifth generation (5G) telecom technologies. On November 6, 2013, Huawei announced plans to invest a minimum of $600 million into R&D for next generation 5G networks capable of speeds 100 times faster than modern LTE networks
