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

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

Aereo Founder to Unveil Wireless Internet Access Startup Dubbed Starry Next Week (Exclusive)

Project Decibel registered a trademark for “Starry” last fall. That trademark application covers “wireless and wired telecommunications and data networking hardware; network routers; wireless routers; wireless access points” as well as “providing access to the Internet; providing access to digital content; Internet access provider services,” amongst other things. […] The company also incorporated a new entity called “Starry Inc.,” which has since registered with the IEEE – a standards body for the wireless industry — to build wireless devices. Separately, Project Decibel became part of the Wi-Fi Alliance, further suggesting that it will build Wifi-based hardware. – Janko Roettgers, Variety

Brand new Wi-Fi standard reaches twice as far and uses less power

According to the Wi-Fi Alliance, 802.11ah “HaLow” is a new standard that features a number of exciting benefits compared to current Wi-Fi technologies. The new standard uses the 900 MHz band and allows wireless signals to reach almost twice as far as current Wi-Fi radios while using less power to broadcast. This will impact not just Wi-Fi routers, which will become far more efficient at killing dead spots, but also mobile phones and IoT devices that will be able to communicate over greater distances while conserving battery life. – Zach Epstein, BGR

New Wireless Tech Will Free Us From the Tyranny of Carriers

Project Fi, which is still invite-only, is a wireless service that rides on both T-Mobile and Sprint’s networks, depending on which one has the strongest signal. If local WiFi is available, it will switch to that network, and even route calls over it. Instead of paying a monthly fee to both T-Mobile and Sprint, customers pay Google a lump fee, and Google handles paying out the carriers. – Klint Finley, WIRED

Comcast slowly rolls out DOCSIS 3.1 for 1Gbps speeds over cable infrastructure

DOCSIS, which stands for Data Over Cable Service Interface Specification, is a standard used to transfer data over the existing network that was installed to provide cable TV service. Most modern internet providers use DOCSIS 3.0 for internet service, often topping out at 100Mbps, or about one tenth the speed of Comcast’s new service. The DOCSIS 3.1 standard is actually capable of up to 10Gbps downstream speeds, but tops out at 1Gbps uploads. – James Risley, GeekWire

New York is finally installing its promised public gigabit Wi-Fi

The full network will install more than 7,500 public hubs throughout the city, each replacing a pre-existing phone booth. Once completed, the hubs will also include USB device charging ports, touchscreen web browsing, and two 55-inch advertising displays. The city estimates that ads served by the new hubs will generate more than $500 million in revenue over the next 12 years. – Russell Brandom, The Verge

Here’s What Wi-Fi Would Look Like If We Could See It

Wifi waves travel through space as rapid, data encoded pulses or waves. A freeze frame of these pulses would show that the pulses are about 6 inches apart (as shown by the lightly colored bands traveling through space in this image). Wifi routers are basically antenna that can send data over multiple frequencies all at the same time. These multiple frequencies are shown as blue, green, yellow, and red colors that pervade the space around the mall. The data from these multiple frequencies swirls around in space as shown here, but can be translated using a common tag system understood by wireless devices. – Meghan Neal, MOTHERBOARD
