Fourth generation, 4G: This was an all-IP based technology capable of providing data rates up to 1 Gbps.The original technology was enhanced to allow data up to 14 Mbps and more. Third generation, 3G: The aim of this technology was to provide high speed data.Second generation, 2G: These were based around digital technology and offered much better spectrum efficiency, security and new features such as text messages and low data rate communications.Although revolutionary in their time they offered very low levels of spectrum efficiency and security. First generation, 1G: These phones were analogue and were the first mobile or cellular phones to be used.The new releases also contain updates for previous systems - Release 14, for example contained many new elements of functionality for LTE as well as updates etc, for UMTS and GSM.Īs the different generations of cellular telecommunications have evolved, each one has brought its own improvements. As 5G started to be developed, it too was incorporated into the standards. Previous releases contained the standards for GSM, UMTS and LTE. The 3GPP standards are updated as specific releases - each release refining elements that have already been described, and introducing new functionality.
Also as the standard are international not only can different companies work on different elements of the system and know they will interoperate, but also for the user, capabilities like roaming are available, and the cost of phones, calls, etc are reduced as a result of the savings of scale, etc. In this way the standards are written and developed.īy having a main industry organisation that controls the standards, interested parties are able to influence the standards to ensure that the required functionality is obtained. They draw on industry expert who give of their time and are sponsored by relevant mobile communications companies. Building on 2G GSM, 3G UMTS and then 4G LTE, the 5G standard come under the auspices of 3GPP - Third generation Partnership Project.ģGPP has a number of different work groups, each addressing different elements of the required standards.
WHAT IS 5G TECHNOLOGY PPT SERIES
Like all widely used systems, the 5G mobile communications is governed by a series of standards. The new 5G technology has been driven by specific uses ad applications.ĥG mobile communications has been driven by the need to provide ubiquitous connectivity for applications as diverse as automotive communications, remote control with haptic style feedback, huge video downloads, as well as the very low data rate applications like remote sensors and what is being termed the IoT, Internet of Things.ĥG is able to provide much greater flexibility and therefore it is able to support a much wider range of applications, from low data rate Internet of Things requirements through to very fast data rate and very low latency applications. Previous systems had evolved driven more by what could be done with the latest technology. The new 5G technology is not just the next version of mobile communications, evolving from 1G to 2G, 3G, 4G, but it provides a new approach giving ubiquitous connectivity.ĥG technology is very different. The 5G mobile communications system provides a far higher level of performance than the previous generations of mobile communications systems. 5G Technology: 5G mobile communications The new 5G mobile communications system will enable many new mobile capabilities to be realised - offering high speed, enormous capacity, IoT capability, low latency and much more it provides the bearer for many new applications.ĥG Cellular Technology Tutorial Includes:ĥG Technology 5G Requirements 5G NR, New Radio 5G NG NextGen Network 5G waveforms & modulation 5G multiple access scheme 5G mmWave Massive MIMO & beam-forming Frequency bands & channels Data channels: physical, transport & logical Voice over New Radio, VoNR
