'First 5G mobile net connection' claimed by Qualcomm

Today, 02:31 AM

Qualcomm has demonstrated mobile internet speeds of 1Gbps using 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 does not yet exist, but it promises faster data speeds and more bandwidth to carry more web traffic.

Qualcomm is describing the demonstration as a "major milestone", but one expert is playing it down.

1Gbps is equivalent to 1,000Mbps, and this speed would enable you to download a one-hour TV programme in HD from BBC iPlayer in less than six seconds.

"It's not a big deal," Prof William Webb, a independent consultant and author of the book The 5G Myth: When vision decoupled from reality, told the BBC.

"5G is not yet clearly defined, they've just postulated what they think it will look like.

"It's not 5G in its final form, so it's premature to say it's a 5G demonstration."

Prof Webb added that speeds higher than 1Gbps were already achievable on 4G.

For example, Huawei's Kirin 970 chipset offered mobile speeds of up to 1.2Gbps when used with compatible network equipment.

Qualcomm said the demonstration, at its laboratories in San Diego, had used its first dedicated 5G chip, the Snapdragon X50 NR modem chipset, on the 28GHz millimetre wave spectrum band.

"This demonstration... was only the first data connection on this 5G mode," said a spokesman for the firm.

"When it is finished and ready to ship to smartphone makers, it will be capable of 5Gbps speed, which no 4G LTE chip currently available can support.

"What our announcement represents is the first steps we are taking to counter sceptics like Prof Webb: yes, millimetre wave 5G is a viable technology for mobile devices and networks, and our achievement proves the steady progress we are making."

What is 5G?

Today's 4G mobile networks currently make use of the sub-6GHz frequencies, but these are now heavily crowded.

Mobile operators are running out of capacity to carry the huge amounts of web traffic generated by consumers on billions of mobile devices, in addition to data being sent from internet-enabled sensors in smart devices.

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

Some of the technologies involve optimising the current 4G network by making the transit of data more efficient, in order to offer greater capacity and higher speeds.

But there are also plans to make use of the currently unused 28GHz and 39GHz millimetre wave spectrum bands, which are found in the electromagnetic spectrum between microwaves and infrared waves.

Millimetre waves offer far more bandwidth than the sub-6GHz frequencies, but the radio signal deteriorates if data is transmitted over more than a few kilometres.

"There are many different definitions of 5G, some of which could be implemented by 2019, and those that wouldn't be, such as millimetre wave, which will probably take a lot longer," said Prof Webb.

Qualcomm takes issue with this analysis, saying that it aims to have millimetre wave-capable smartphones in users' hands before July 2019, when it expects the first compatible networks to have become available.

Child safety smartwatches ‘easy’ to hack, watchdog says

Today, 02:30 AM

Some smartwatches designed for children have security flaws that make them vulnerable to hackers, a watchdog has warned.


The Norwegian Consumer Council (NCC) tested watches from brands including Gator and GPS for Kids.
It said it discovered that attackers could track, eavesdrop or even communicate with the wearers.

The manufacturers involved insist the problems have either already been resolved or are being addressed.

UK retailer John Lewis has withdrawn one of the named smartwatch models from sale in response.

The smartwatches tested essentially serve as basic smartphones, allowing parents to communicate with their children as well as track their location.
Some include an SOS feature that allows the child to instantly call their parents.

They typically sell for about £100.

The NCC said it was concerned that Gator and GPS for Kids' watches transmitted and stored data without encryption.
It said that meant strangers, using basic hacking techniques, could track children as they moved, or make a child appear to be in a completely different location.

Consumer rights watchdog Which? criticised the "shoddy" watches and said parents "would be shocked" if they knew the risks.

Spokeswoman Alex Neill said: "Safety and security should be the absolute priority. If that can't be guaranteed, then the products should not be sold."

John Lewis stocks a version of the Gator watch, although it is not clear whether it suffers from the same security flaws as the watches tested.

The firm said it was withdrawing the product from sale "as a precautionary measure" while awaiting "further advice and reassurance from the supplier".
GPS for Kids said it had resolved the security flaws for new watches and that existing customers were being offered an upgrade.

The UK distributor of the Gator watch said it had moved its data to a new encrypted server and was developing a new, more secure app for customers.

Hurricane Irma will be 'devastating' to US - Fema head

08 September 2017 - 01:01 PM

Hurricane Irma will "devastate" either Florida or neighbouring states, the head of the US federal emergency agency has said.

Brock Long said parts of Florida would be without power for days. Half a million people in the state have been ordered to leave their homes.

Hurricane Irma has left a trail of destruction in the Caribbean, affecting an estimated 1.2m people.
At least 20 people are known to have died so far.

It has been downgraded to a category four storm, but officials warn that it remains "extremely dangerous".
The US National Weather Service says that Irma was expected to bring wind speeds of around 165mph (270km/h) over the weekend as it hits Florida.
"Hurricane Irma continues to be a threat that is going to devastate the United States in either Florida or some of the south-eastern states," Mr Long said.
"The entire south-eastern United States better wake up and pay attention," he added.
 
Florida Governor Rick Scott said all Floridians should be prepared for possible evacuation, and issued a stark warning to those in threatened areas.
"We are running out of time. If you are in an evacuation zone, you need to go now," he told reporters.
"Remember, we can rebuild your home, we can't rebuild your life."
The death toll continued to rise on Friday in the Caribbean.

France's Interior Minister Gérard Collomb said nine people were dead and seven missing in the French territory on St Martin, an island shared with the Netherlands, and St Barthélemy, known more commonly as St Barts. Another death - the second - has been confirmed in the Dutch territory of Sint Maarten.

French officials said six out of 10 homes on Saint-Martin were so badly damaged that they were uninhabitable.

The US Consulate General in Curacao said it believes an estimated 6,000 Americans are stranded on the island.
French, British and Dutch military authorities have deployed aid - including warships and planes equipped with food, water and troops - to their territories

Reporting from another badly damaged island, Barbuda, the BBC's Laura Bicker says the destruction there is worse than feared.
 
Where is Irma - and where next?
The storm lashed the Turks and Caicos islands and brought torrential rain to the Dominican Republic and Haiti, before battering the north coast of Cuba and the central Bahamas.

A huge evacuation of south-eastern, low-lying coastal areas in the Bahamas has been ordered. The tourism ministry said in a video statement that thousands of tourists left before the storm's arrival.
Meanwhile Mr Long predicted a "truly devastating" impact on Florida.
South Florida "may be uninhabitable for weeks or months" because of the storm, the US National Weather Service said.

On the archipelago of Turks and Caicos, with its population of about 35,000, one witness described a drop in pressure that could be felt in people's chests.
Irma ripped off roofs on the capital island, Grand Turk, flooded streets, snapped utility poles and caused a widespread black-out.
Governor John Freeman told the BBC that people in low-lying areas were evacuated and sent to shelters. The islands' highest point is only 50m (163ft).
Irma also caused some damage to roofs, flooding and power outages in the northern parts of the Dominican Republic and Haiti.

Turks and Caicos Islands: widespread damage, although extent unclear
Barbuda: the small island is said to be "barely habitable", with 95% of the buildings damaged. Antigua and Barbuda Prime Minister Gaston Browne estimates reconstruction will cost $100m (£80m). One death has been confirmed
Anguilla: extensive damage with one person confirmed dead
Puerto Rico: more than 6,000 residents of the US territory are in shelters and many more without power. At least three people have died
British Virgin Islands: widespread damage reported
US Virgin Islands: damage to infrastructure was said to be widespread, with four deaths confirmed
Haiti and the Dominican Republic: Both battered by the storm, but neither had as much damage as initially feared
