2021's smartphones will greatly ease the 5G transition for US carriers – Android Police

Published

 on


While you can’t even buy more than two smartphones with Qualcomm’s brand-new X55 5G modem in the US right now, the company has already announced the part that will replace it: the Snapdragon X60, and it comes with some seriously important improvements for US cellular operators.

I know that topics like spectrum and carrier aggregation can make anyone’s eyes glaze over, but stick with me here, because this actually is kind of good stuff to know. Right now, most carriers in the US (and all of the “big four,” soon to be big three) rely on a large diversity of various spectrum holdings to provide their 4G LTE coverage. But because these many different “bands” aren’t contiguous, carriers employ a technology known as Carrier Aggregation (CA) to combine signal from all those various bands on demand to greatly improve connection speeds. Right now, phones like the Galaxy S10 can combine up to seven 20MHz chunks of 4G signal to achieve a much faster connection.

Qualcomm’s current 5G modems, the Snapdragon X50, X52, and X55, all still support 4G carrier aggregation, but none of them support the technology on 5G, at least on America’s largely FDD networks. The best that they can do is take a 5G mmWave signal (which remains exceedingly rare) and combine it with a 4G signal to slightly boost download speeds. But if a carrier deploys, say, four different bands of low or mid-band 5G, no smartphone can currently combine those bands into a single, much faster connection. Your phone just has to pick one.

As a result, 5G may actually be substantially slower than 4G on some carriers depending on where you are and how congested each network is.

This is a particular problem for AT&T, which employs the highest diversity of low frequency 4G bands that can be combined using carrier aggregation (Sprint, Verizon, and T-Mobile all use CA as well, but to a lesser extent). Right now, AT&T’s “5Ge” network, which is really just a name for its LTE Advanced (Pro?) network, heavily leverages carrier aggregation to achieve higher peak speeds in some of its most important and dense markets. But as AT&T’s low-band 5G network rolls out, it’s going to run into a real problem: even with technology like Dynamic Spectrum Sharing (DSS), it can’t redeploy too much of that 4G spectrum as 5G until a lot of its subscribers have smartphones that support 5G carrier aggregation. AT&T, though, is just the most affected by this issue: all US carriers will have to consider how and when to refarm their low-band spectrum to 5G, and 5G carrier aggregation is a key consideration in doing so.

Enter the Snapdragon X60. The X60 is the first 5G modem from Qualcomm that will support 5G carrier aggregation across a diversity of bands. It will be able to aggregate not only within sub-6GHz bands, but across mmWave and sub-6GHz bands, and do so regardless of whether those bands are TDD, FDD (the dominant standard in the US), or both. 5G carrier aggregation is a critical step as we move toward the deployment of standalone (SA) 5G networks that will see not just the periphery and edges of networks employ 5G standards, but carriers’ entire core network infrastructures. That will eventually lead to things like the ultra-low-latency networks we’ve been promised as part of the 5G experience. Still, it’s going to take years for this technology to proliferate, and 5G carrier aggregation is just one piece of a very, very large puzzle as we slowly make our way forward.

Unfortunately, we’re already hitting road blocks. T-Mobile has indicated to investors that an arguably even more important stepping stone in transitioning our legacy 4G low-band networks to 5G has hit a serious snag, saying that DSS is performing much more poorly than anticipated in initial testing (for what it’s worth, Verizon contests this characterization of the situation).

Ottawa orders TikTok’s Canadian arm to be dissolved

Published

 on

 

The federal government is ordering the dissolution of TikTok’s Canadian business after a national security review of the Chinese company behind the social media platform, but stopped short of ordering people to stay off the app.

Industry Minister François-Philippe Champagne announced the government’s “wind up” demand Wednesday, saying it is meant to address “risks” related to ByteDance Ltd.’s establishment of TikTok Technology Canada Inc.

“The decision was based on the information and evidence collected over the course of the review and on the advice of Canada’s security and intelligence community and other government partners,” he said in a statement.

The announcement added that the government is not blocking Canadians’ access to the TikTok application or their ability to create content.

However, it urged people to “adopt good cybersecurity practices and assess the possible risks of using social media platforms and applications, including how their information is likely to be protected, managed, used and shared by foreign actors, as well as to be aware of which country’s laws apply.”

Champagne’s office did not immediately respond to a request for comment seeking details about what evidence led to the government’s dissolution demand, how long ByteDance has to comply and why the app is not being banned.

A TikTok spokesperson said in a statement that the shutdown of its Canadian offices will mean the loss of hundreds of well-paying local jobs.

“We will challenge this order in court,” the spokesperson said.

“The TikTok platform will remain available for creators to find an audience, explore new interests and for businesses to thrive.”

The federal Liberals ordered a national security review of TikTok in September 2023, but it was not public knowledge until The Canadian Press reported in March that it was investigating the company.

At the time, it said the review was based on the expansion of a business, which it said constituted the establishment of a new Canadian entity. It declined to provide any further details about what expansion it was reviewing.

A government database showed a notification of new business from TikTok in June 2023. It said Network Sense Ventures Ltd. in Toronto and Vancouver would engage in “marketing, advertising, and content/creator development activities in relation to the use of the TikTok app in Canada.”

Even before the review, ByteDance and TikTok were lightning rod for privacy and safety concerns because Chinese national security laws compel organizations in the country to assist with intelligence gathering.

Such concerns led the U.S. House of Representatives to pass a bill in March designed to ban TikTok unless its China-based owner sells its stake in the business.

Champagne’s office has maintained Canada’s review was not related to the U.S. bill, which has yet to pass.

Canada’s review was carried out through the Investment Canada Act, which allows the government to investigate any foreign investment with potential to might harm national security.

While cabinet can make investors sell parts of the business or shares, Champagne has said the act doesn’t allow him to disclose details of the review.

Wednesday’s dissolution order was made in accordance with the act.

The federal government banned TikTok from its mobile devices in February 2023 following the launch of an investigation into the company by federal and provincial privacy commissioners.

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Google’s partnership with AI startup Anthropic faces a UK competition investigation

Published

 on

 

LONDON (AP) — Britain’s competition watchdog said Thursday it’s opening a formal investigation into Google’s partnership with artificial intelligence startup Anthropic.

The Competition and Markets Authority said it has “sufficient information” to launch an initial probe after it sought input earlier this year on whether the deal would stifle competition.

The CMA has until Dec. 19 to decide whether to approve the deal or escalate its investigation.

“Google is committed to building the most open and innovative AI ecosystem in the world,” the company said. “Anthropic is free to use multiple cloud providers and does, and we don’t demand exclusive tech rights.”

San Francisco-based Anthropic was founded in 2021 by siblings Dario and Daniela Amodei, who previously worked at ChatGPT maker OpenAI. The company has focused on increasing the safety and reliability of AI models. Google reportedly agreed last year to make a multibillion-dollar investment in Anthropic, which has a popular chatbot named Claude.

Anthropic said it’s cooperating with the regulator and will provide “the complete picture about Google’s investment and our commercial collaboration.”

“We are an independent company and none of our strategic partnerships or investor relationships diminish the independence of our corporate governance or our freedom to partner with others,” it said in a statement.

The U.K. regulator has been scrutinizing a raft of AI deals as investment money floods into the industry to capitalize on the artificial intelligence boom. Last month it cleared Anthropic’s $4 billion deal with Amazon and it has also signed off on Microsoft’s deals with two other AI startups, Inflection and Mistral.
