5G high-speed data ‘milestone’ claims


Qualcomm has shown that mobile internet speeds of 1Gbit / s over a 5G-smartphone-chip.

The chipset manufacturer claims this is the first working 5G data connection on a mobile device.

The fifth generation of the mobile network is not yet available, but it promises faster data speeds and more bandwidth, more web traffic.

Qualcomm describes the demonstration as “an important milestone”, but is an expert, play it down.

1Gbit / s is equivalent to 1,000 Mbit / s, this speed allows you to download a hour TV-program in HD from BBC iPlayer in less than six seconds.

“It’s not a big deal,” Prof William Webb, an independent consultant and author of the book the 5G myth: If the vision is decoupled from reality, told the BBC.

“5G is not yet defined clearly, you have posited is only what you think, it will look like.

“It is not 5G in its final form, so it is premature to say it is a 5G demonstration.”

Prof Webb said, adding that speeds of more than 1Gbit / s have already been achievable on 4G.

For example, Huawei’s Kirin 970 chip set of the mobile speed of up to 1.2 Gbit / s when used with compatible network equipment offered.

Qualcomm said the demonstration at his laboratory in San Diego, had mm his first dedicated 5G-chip, the Snapdragon-X50-NR-modem chip set, in the 28GHz-wave spectrum band.What is 5G?

Today’s 4G mobile networks currently use the sub-6GHz frequencies, but these are now overcrowded.

Mobile operator runs the capacity to carry the huge amounts of web traffic generated by consumers and billions of mobile devices, in addition to the data sent by internet-enabled sensors in smart devices.

The specifications for 5G have not yet been defined by the global mobile standards body 3GPP, so that different parts of the industry try out the different technologies, with the hope that 5G will be ready by 2019.

Some of the technologies include the optimization of the current 4G network by the transit of data in a more efficient, more capacity and higher speeds.

But there are also plans currently unused 28GHz and 39GHz Millimeter-wave spectrum bands in the electromagnetic spectrum between microwaves and infrared waves.

Millimeter-waves offer far more bandwidth than the sub-6GHz frequencies, but the radio signal deteriorates when data are transmitted, the more than a few kilometers.

“There are many different definitions of 5G, some of which could be implemented until 2019, and those not, would be that the mm-wave, which is likely to take much longer,” said Prof Webb.
