tests of the 5G the fifth generation of mobile networks, began to leave the role in 2015, but only in this year have been conducted significant changes of the technology industry to bring this new technology to consumers. Industry giants chip such as Qualcomm and Intel, players in the area of infrastructure such as Ericsson and Nokia, and, of course, the main mobile telephony operators have surprised with the announcement of numerous advances in the development of technology and field testing in the last few months. On the face of it, to give an idea to the reader of projects that are in progress, Computerworld made a schedule of the tests with a 5G that are in progress.
Two of the projects the most talked-about technology 5G started in 2014 ─ a was NTT DoCoMo, of Japan, and the other of the AT & T, at Middletown, in the USA, but tests on a large scale does not descolaram until recently.
The new wave of ad networks 5G began, in reality, at the Mobile World Congress this year. However, a number of operators, suppliers of smartphones and the networks had announced in ferevereiro testing of 5G. But the main news was that the the Federal Communications Commission (FCC), responsible for regulating the telecommunications sector in the us, decided free up the frequency bands that the technology 5G will need to use.
The Ericsson and Nokia, in particular, have been very active and been involved in numerous tests with numerous partners. This protgagonismo makes sense, given that the technology 5G can generate a cycle of modernisation of the networks particularly lucrative ─ a large number of base stations smaller, deployed to cover the areas of demand dense, will control a large part of the networks 5G.
Qualcomm has also assumed a role of the bow in relation to technology 5G, as a large proportion of data 5G, especially in the USA, trafegarão for terminals that use its semiconductors. The manufacturer of the chip has been involved deeply in the tests and in the research of the technology, usually in partnership with carriers and hardware manufacturers.
The accelerated pace of research and development means that we are closer than ever’s patterns and functional reference design for 5G, which is a prerequisite for mass deployment of the technology.
Is pereciso warn that operators, equipment manufacturers and other parties involved have been unstinting in trumpeting that they are working on technology 5G, but disclose precise dates and the specific nature of their tests. This suggests that these companies think that there is some competitive differentiation to be achieved.
The main operators of the U.S., particularly, have remained relatively silent on the subject. But this does not mean that they do not have projects 5G. Sprint, for example, has demonstrated its technology of centimeter wave (15 GHz) in a game of football at the Copa America, in Philadelphia, providing download speeds of 4 Gbps for the participants and viewing live video feeds of 4 K.
The recent test of the technology of millimetre wave (70 GHz) of NTT DoCoMo provided 48 Gbps of throughput (transfer fee), and T-Mobile says it has reached 12 Gbps with less than 2 milliseconds of latency.
These numbers are more than attractive, no doubt, but they are a drop of water in the ocean, given that the target speed real-connectivity-5G is around 100 Mbps to 1Gbps, depending on the context and who is speaking, which reflects the great demand load of an environment in the real world. But even at the lower limit, it is worth noting that this is approximately ten times faster than the average connections 4G in the U.S., according to a report released in February by the OpenSignal.
The timeline for the general availability of 5G provides that the labour standards will be completed by 2018 or 2019, and the deployment on the clients should occur by 2020. The Ericsson, one of the main protagonists in the development of 5G, recently announced that about a quarter of the mobile devices existing in the world will use the technology 5G up to 2022, which approximates the forecast of many analysts that provide for 2023 as the approximate date of availability of networks 5G.
to be true is that the technology 5G should still take time to reach out to the consumers, since even there is a long way to go. Even because the International Telecommunications Union (ITU) only provides for setting the specifications in 2020.
