Tethering your laptop and phone can be a bit of a hassle. Google’s Chrome OS has long offered a solution called Instant Tethering that makes the process automatic, but so far, this only worked for a small set of Google’s own Chromebooks and phones, starting with the Nexus 6. Now Google is officially bringing this feature to a wider range of devices after testing it behind a Chrome OS flag for a few weeks. With this, Instant Tethering is now available on an additional 15 Chromebooks and more than 30 phones.
The promise of Instant Tether is pretty straightforward. Instead of having to turn on the hotspot feature on your phone and then manually connecting to the hotspot from your device (and hopefully remembering to turn it off when you are done), this feature lets you do this once during the setup process and then, when the Chromebook doesn’t have access to a Wi-Fi network, it’ll simply create a connection to your phone with a single click. If you’re not using the connection for more than 10 minutes, it’ll also automatically turn off the hotspot feature on the phone, too.
Tethering, of course, counts against your cell plan’s monthly data allotment (and even most “unlimited” plans only feature a limited number of GB for tethering), so keep that in mind if you decide to turn on this feature.
You can find the full list of newly supported devices, which include many of today’s most popular Android phones and Chromebooks, below.

Last year, four of the largest U.S. cell carriers were caught selling and sending real-time location data of their customers to shady companies that sold it on to big spenders, who would use the data to track anyone “within seconds” for whatever reason they wanted.
At first, little-known company LocationSmart was obtaining (and leaking) real-time location data from AT&T, Verizon, T-Mobile and Sprint and selling access through another company, 3Cinteractive, to Securus, a prison technology company, which tracked phone owners without asking for their permission. This game of telephone with people’s private information was discovered, and the cell carriers, facing heavy rebuke from Sen. Ron Wyden, a privacy-minded lawmaker, buckled under the public pressure and said they’d stop selling and sharing customers’ locations.
And that would’ve been that — until it wasn’t.
Now, new reporting by Motherboard shows that while LocationSmart faced the brunt of the criticism, few focused on the other big player in the location-tracking business, Zumigo. A payment of $300 and a phone number was enough for a bounty hunter to track down the participating reporter by obtaining his location using Zumigo’s location data, which was continuing to pay for access from most of the carriers.
Worse, Zumigo sold that data on — like LocationSmart did with Securus — to other companies, like Microbilt, a Georgia-based credit reporting company, which in turn sells that data on to other firms that want that data. In this case, it was a bail bond company, whose bounty hunter was paid by Motherboard to track down the reporter — with his permission.
Everyone seemed to drop the ball. Microbilt said the bounty hunter shouldn’t have used the location data to track the Motherboard reporter. Zumigo said it didn’t mind location data ending up in the hands of the bounty hunter, but still cut Microbilt’s access.
But nobody quite dropped the ball like the carriers, which said they would not to share location data again.
T-Mobile, at the center of the latest location-selling revelations for passing the reporter’s location to the bounty hunter, said last year in the midst of the Securus scandal that it “reviewed” its real-time location data sharing program and found appropriate controls in place. To appease even the skeptical, T-Mobile chief executive John Legere tweeted at the time that he “personally evaluated the issue” and promised that the company “will not sell customer location data to shady middlemen.”
It’s hard to see how that isn’t, in hindsight, a downright lie.
Sounds like word hasn’t gotten to you, @ronwyden. I’ve personally evaluated this issue & have pledged that @tmobile will not sell customer location data to shady middlemen. Your consumer advocacy is admirable & we remain committed to consumer privacy. https://t.co/UPx3Xjhwog

This time around, T-Mobile said it “does not have a direct relationship” with Microbilt but admitted one with Zumigo, which, given the story and the similarities to last year’s Securus scandal, could be considered one of many “shady middlemen” still obtaining location data from cell carriers.
Legere later said in a tweet late Wednesday that the company “is completely ending” its relationships with location aggregators in March, almost a year after the company was first implicated in the first location-sharing scandal.
It wasn’t just T-Mobile. Other carriers were also still selling and sharing their customers’ data.
AT&T said in last year’s letter it would “protect customer data” and “shut down” Securus’ access to its real-time store of customer location data. Most saw that as a swift move to prevent third-parties accessing customer location data. Now, AT&T seemed to renege on that year-ago pledge, saying it will “only permit the sharing of location” in limited cases, including when required by law.
Sprint didn’t say what its relationship was with either Zumigo or Microbilt, but once again — like last year — cited its privacy policy as its catch-all to sell and share customer location data. Yet Sprint, like its fellow carriers AT&T and T-Mobile, which pledged to stop selling location data, clearly didn’t complete its “process of terminating its current contracts with data aggregators to whom we provide location data” as it promised in a letter a year ago.
Verizon, the parent company of TechCrunch, wasn’t explicitly cleared from sharing location data with third-parties in Motherboard’s report — only that the bounty hunter refused to search for a Verizon number. (We’ve asked Verizon if it wants to clarify its position — so far, we’ve had nothing back.)
In a letter sent last year when the Securus scandal blew up, Verizon said it would “take steps to stop” sharing data with two firms — Zumigo and LocationSmart, an intermediary that passed on obtained location data to Securus. But that doesn’t mean it’s off the hook. It was still sharing location data with anyone who wanted to pay in the first place, putting its customers at risk from hackers, stalkers — or worse.
Wyden. who tweeted about the story, said carriers selling customer location data “is a nightmare for national security and the personal safety of anyone with a phone.” And yet there’s no way to opt out — shy of a legislative fix — given that two-thirds of the U.S. population aren’t going to switch to a carrier that doesn’t sell your location data.
It turns out, you really can’t trust your cell carrier. Who knew?

After a recent update some AT&T phones now have a 5G E icon. This icon replaces the one indicated the phone is running on a 4G network. But here’s the thing: The phone is still on a 4G network. AT&T has played these games before, too.
This nonsense is a marketing ploy by AT&T. The so-called 5G E (5G Evolution) network is just a beefed-up 4G network and not true 5G, which is still far from being ready for general consumption. AT&T used the same deceptive tactics before launching its LTE network.
Right now only select phones in a few markets will see the change. The wireless carrier intends to roll out this madness to even more phones and even more markets throughout the year.
Disclosure: TechCrunch is a Verizon Media company.

Google’s Project Fi wireless service is getting a major update today that introduces an optional always-on VPN service and a smarter way to switch between Wi-Fi and cellular connections.
By default, Fi already uses a VPN service to protect users when they connect to the roughly two million supported Wi-Fi hotspots. Now, Google is expanding this to cellular connections, as well. “When you enable our enhanced network, all of your mobile and Wi-Fi traffic will be encrypted and securely sent through our virtual private network (VPN) on every network you connect to, so you’ll have the peace of mind of knowing that others can’t see your online activity,” the team writes in today’s announcement.
Google notes that the VPN also shields all of your traffic from Google itself and that it isn’t tied to your Google account or phone number.
The VPN is part of what Google calls its “enhanced network” and the second part of this announcement is that this network now also allows for a faster switch between Wi-Fi and mobile networks. When you enable this — and both of these features are currently in beta and only available on Fi-compatible phones that run Android Pie — your phone will automatically detect when your Wi-Fi connection gets weaker and fill in those gaps with cellular data. The company says that in its testing, this new system reduces a user’s time without a working connection by up to 40 percent.
These new features will start rolling out to Fi users later this week. They are off by default, so you’ll have to head to the Fi Network Tools in the Project Fi app and turn them on to get started. One thing to keep in mind here: Google says your data usage will likely increase by about 10 percent when you use the VPN.

Everyone seems to be insisting on installing cameras all over their homes these days, which seems incongruous with the ongoing privacy crisis — but that’s a post for another time. Today, we’re talking about enabling those cameras to send high-definition video signals wirelessly without killing their little batteries. A new technique makes beaming video out more than 99 percent more efficient, possibly making batteries unnecessary altogether.
Cameras found in smart homes or wearables need to transmit HD video, but it takes a lot of power to process that video and then transmit the encoded data over Wi-Fi. Small devices leave little room for batteries, and they’ll have to be recharged frequently if they’re constantly streaming. Who’s got time for that?
The idea behind this new system, created by a University of Washington team led by prolific researcher Shyam Gollakota, isn’t fundamentally different from some others that are out there right now. Devices with low data rates, like a digital thermometer or motion sensor, can something called backscatter to send a low-power signal consisting of a couple of bytes.
Backscatter is a way of sending a signal that requires very little power, because what’s actually transmitting the power is not the device that’s transmitting the data. A signal is sent out from one source, say a router or phone, and another antenna essentially reflects that signal, but modifies it. By having it blink on and off you could indicate 1s and 0s, for instance.
UW’s system attaches the camera’s output directly to the output of the antenna, so the brightness of a pixel directly correlates to the length of the signal reflected. A short pulse means a dark pixel, a longer one is lighter, and the longest length indicates white.
Some clever manipulation of the video data by the team reduced the number of pulses necessary to send a full video frame, from sharing some data between pixels to using a “zigzag” scan (left to right, then right to left) pattern. To get color, each pixel needs to have its color channels sent in succession, but this too can be optimized.
Assembly and rendering of the video is accomplished on the receiving end, for example on a phone or monitor, where power is more plentiful.
In the end, a full-color HD signal at 60FPS can be sent with less than a watt of power, and a more modest but still very useful signal — say, 720p at 10FPS — can be sent for under 80 microwatts. That’s a huge reduction in power draw, mainly achieved by eliminating the entire analog to digital converter and on-chip compression. At those levels, you can essentially pull all the power you need straight out of the air.
They put together a demonstration device with off-the-shelf components, though without custom chips it won’t reach those
A frame sent during one of the tests. This transmission was going at about 10FPS.
microwatt power levels; still, the technique works as described. The prototype helped them determine what type of sensor and chip package would be necessary in a dedicated device.
Of course, it would be a bad idea to just blast video frames into the ether without any compression; luckily, the way the data is coded and transmitted can easily be modified to be meaningless to an observer. Essentially you’d just add an interfering signal known to both devices before transmission, and the receiver can subtract it.
Video is the first application the team thought of, but there’s no reason their technique for efficient, quick backscatter transmission couldn’t be used for non-video data.
The tech is already licensed to Jeeva Wireless, a startup founded by UW researchers (including Gollakota) a while back that’s already working on commercializing another low-power wireless device. You can read the details about the new system in their paper, presented last week at the Symposium on Networked Systems Design and Implementation.

SteelSeries has two new Arctis Pro gaming headsets out, and they pack a lot of tech and versatility into a comfortable, visually attractive package. The SteelSeries Arctis Pro Wireless and Arctis Pro + GameDAC are both incredibly capable headsets that deliver terrific sound, and depending on your system needs, should probably be your first choice when looking for new gaming audio gear.
The Arctis Pro Wireless is, true to its name, wire-free, but also promises lossless 2.4GHz transmission to ensure lag-free audio, too – a must for competitive gaming. The combination of the wireless functionality, the long-wearing comfort of the suspension system headband and the included transmitter base that can hold and charge a swappable battery as well as display all key information on an OLED readout makes this a standout choice.
There are some limitations, however – compatibility is limited to either PS4 or PC for this one, for instance. The wired Arctis Pro (without GameDAC) is compatible with the Xbox One, but both the wireless version and the version that connected to the wired DAC will only work with either Sony’s latest consoles or with a Windows or Mac-based gaming PC.
I’m a bit saddened by that since I’m a big fan of PUBG on Xbox, and also lately of Sea of Thieves, but I also do regularly play PS4 and PC games, and the Arctis Pro Wireless is my weapon of choice now when using either, either for multiplayer or single player games. The wearability and sound quality (which includes DTS X 7.1 surround on PC) is so good that I’ll often opt to use them in place of my actual 5.1 physical surround system, even when I don’t need to chat with anyone.

Other options, like the Turtle Beach Elite Pro Tournament Headset, offer different advantages including more easily accessible fine-tune control over soundscape, balance of chat and game audio and other features, but the SteelSeries offers a less complicated out-of-box experience, and better all-day wearability thanks to taking cues from athletic wear for its materials and design.
The GameDAC option additionally has Hi-Res Audio certificate, which is good if you’re looking to stream FLAC files or high-res audio from services like Tidal. The DAC itself also makes all audio sound better overall, and gives you more equalization options from the physical controller .
The main thing to consider with the Arctis Pro + DAC ($249.99) and the Arctis Pro Wireless ($329.99) is the cost. They’re both quite expensive relative to the overall SteelSeries lineup and those of competitors, too. But in this case, cost really is reflective of quality – channel separation and surround virtualization is excellent on these headsets, and the mic sounds great to other players I talked to as well. Plus, the Pro Wireless can connect to both Bluetooth and the 2.4GHz transmitter simultaneously, so you can use it with your phone as well as your console, and the retractable mic keeps things looking fairly stylish, too.
