Roku is testing its own Wi-Fi extender to improve streaming reliability

The Relay is a small white gadget that plugs into a power outlet and rests alongside the wall. Instructions show that it’s meant to be used with Roku devices to improve their Wi-Fi connection; it isn’t stated whether other devices can be connected to it, too. The product is seemingly being marketed as an extension of Roku players, with the manual directing people to install the Relay halfway between their router and TV. – Jacob Kastrenakes, The Verge » https://ift.tt/2SMmIwx

Wi-Fi branding to get a lot simpler with upcoming “Wi-Fi 6”

The 802.11 group produces dated standards every few years, most recently 802.11-2016, and then publishes amendments to these standards. The amendments are named alphabetically, and it’s these amendment names that have come to be used to refer to particular Wi-Fi technology. For example, the original 802.11-1997 standard was amended by 802.11a (54Mbit/s over 5GHz radio), 802.11b (11Mbit/s over 2.4GHz radio), and 802.11g (54Mbit/s over 2.4GHz) and, correspondingly, we see devices claiming to support 802.11a/b/g. Most of the other letters are also used to define additional features. – Peter Bright, Ars Technica https://ift.tt/2IyzTMt

What is WPA3, why does it matter, and when can you expect it?

WPA, an acronym for Wi-Fi Protected Access, authenticates devices with a pre-shared cryptographic cipher using the Advanced Encryption Standard (AES) protocol. Specifically, it employs a four-way handshake to prevent eavesdroppers from snooping on traffic passing between a Wi-Fi access point (like a router) and a Wi-Fi client (like a smartphone or laptop). Encryption prevents man-in-the-middle attacks that attempt to intercept data in transfer. – Kyle Wiggers, VentureBeat https://ift.tt/2Ivz32e

Roombas will soon build a Wi-Fi coverage map while they clean

As the robot roams around your house cleaning, it will now periodically log the Wi-Fi signal strength throughout the house. The data will be saved in a new Wi-Fi coverage map, which will live inside the Roomba app alongside the cleaning coverage map. Wi-Fi mapping will launch later this month as part of an app update and will mark the launch of a new beta program for the Roomba app. – Ron Amadeo, Ars Technica http://ift.tt/2lNAGz0

Denver has the fastest WiFi of any airport in North America

The folks at Speedtest have done us all a favor and surveyed the offerings at North American airports to suss out the worst to the… surprisingly not-worst. Interestingly enough, a state that legalized recreational marijuana also has the highest uploads and downloads. Denver International Airport boasts 78.22 Mbps downloads and 78.29 Mbps on average, with Speedtest reporting that this actually increased by over 25 percent since its last look. Aéroport Montréal-Trudeau Airport in Canada fared the worst for WiFi, with 1.92 Mbps down and 2 Mbps up on average. – Timothy J. Seppala, Engadget http://engt.co/2urHCru

New York City’s free gigabit WiFi comes to Brooklyn

As before, the LinkNYC kiosks aren’t just about free internet access. You also have free domestic calls (including easy connections to 311 and 911) and USB ports to charge your mobile devices. While you can’t browse the web from them like you could early on, they’re potentially crucial to the homeless, travelers and others who don’t have guaranteed internet and phone service in the Big Apple. – Jon Fingas, Engadget http://ift.tt/2fTC8vQ

Germany plans to remove owner liability for piracy on open Wi-Fi hotspots—report

The country’s coalition government has agreed to change the “Störerhaftung” law, which has led to many people receiving fines for piracy carried out by others using their Wi-Fi connections. The aim is to bring changes in quickly, with a new law coming into force this autumn. Der Spiegel says that both individuals, and businesses offering Wi-Fi as an ancillary service, will be covered by the new exemption. This would represent a dramatic change from the present situation, which has resulted in far fewer open Wi-Fi networks in Germany compared to other countries, according to the report. – Glyn Moody, Ars Technica

We’ve seen the light! Li-Fi is the future of wireless connectivity

Professor Harald Hass started researching this back in 2003, because he saw the upcoming spectrum crunch. He correctly predicted that the lack of radio frequency spectrum for mobile devices would become a real problem. (These days, it’s very difficult to get a connection on some Wi-Fi frequencies if you’re in an urban area.) Around the same time, new LED light technology hit the market, and Hass saw an opportunity to bring the two together. He found a way to use these electronic lighting components for high speed data communication, without interfering with existing radio frequency infrastructures. – Simon Hill, Digital Trends

FCC Allows Further Testing of LTE Service in Unlicensed Spectrum Used by Wi-Fi

The FCC on Friday approved further testing of the approach, known as LTE-U (U for unlicensed), which has been at the center of a struggle between tech heavyweights. For months now, Verizon, Qualcomm and others have been pushing LTE-U, promising that it would allow for more efficient data use by cellular devices while also insisting that it can be a good neighbor with Wi-Fi devices. – Ina FriedIna Fried, Re/code

Super high-speed internet delivered over the air isn’t as crazy as it sounds

[M]illimeter waves, has been achieving this kind of speed over the air for years. As far back as 1997 startups were raising money with the promise of using it to deliver wireless broadband internet service. But the wave of companies that rose during the dot-com boom largely perished because of technical hurdles and an unsustainable business model. The question for Starry is, has the technology improved enough in the last two decades to compete with wireline broadband in terms of reliability, and has the customer base for broadband expanded enough for the business model to flourish. – Ben Popper, The Verge
