A new Wi-Fi standard known as 802.11ac Wave 2 was recently certified by the Wi-Fi Alliance. Here are the six details you need to know.

The Wi-Fi Alliance, a global nonprofit association of companies that determine the interoperability of Wi-Fi technology, recently certified the 802.11ac Wave 2 standard. The new standard brings a host of updates that could eventually affect the daily connectivity of consumers and businesses alike

Here are six performance changes that we will see with 802.11ac Wave 2.

1. It opens up gigabit Wi-Fi possibilities

With all the hype around products like Google Fiber, AT&T GigaPower, and Verizon Fios, it’s safe to say that gigabit internet is hot right now. However, it’s mostly constrained to a hardline connection. Using the Wave 1 standard, gigabit speeds have been achieved in lab settings, but not commonly in the real world.

The Wave 2 standard could open the door for gigabit Wi-Fi, though. The PHY (physical) rate, which in turn affects the throughput rate of data transfer, is much higher in Wave 2. Wave 1 PHY rate maxes out at 1.3 Gbps, while Wave 2 can be 2.34 Gbps. Even if the throughput was 50% lower than the theoretical PHY rate for Wave 2, in theory it would still be above 1 Gbps.

2. It supports more connected devices

Wave 2 offers offers greater density than Wave 1in that it supports multiuser multiple input, multiple output (MU-MIMO). This means that the spectrum is used more efficiently for multiple connected devices, and devices can more easily get on and off of the network.

Gartner research vice president Tim Zimmerman said it is: “The ability for the access point to communicate simultaneously with multiple mobile devices in a single coverage area.” The access point will be able to talk to up to four, single stream devices at one time going downstream.

The support of MU-MIMO is important for consumer users, as most people tend to have multiple connected devices in their home or on their person, but it’s also good new for businesses. The growing number of mobile devices and IoT-connected devices have created some frustrations for network admins, and the addition of MU-MIMO support could help alleviate some of those headaches.

3. It offers stronger performance

In addition to the stronger PHY rate, it also adds the option for 160 MHz channel width. Previously, in Wave 1, the only options were 20, 40, and 80 MHz. In theory this will make it easier to access and transfer large files.

The Wave 2 standard also adds a fourth spatial stream, up from the three streams offered in Wave 1. According to the Wi-Fi Alliance, “Device speeds are proportional to the number of spatial streams.” So, more streams should mean better overall performance.

4. It brings more bandwidth and flexibility

One of the biggest updates that comes with 802.11ac Wave 2 is that it supports additional 5 GHz channels. If these channels are designated for Wi-Fi use, it could help support more users and devices overall. Most devices (65% according to the Wi-Fi Alliance) now are dual-band, meaning they can operate in both the 2.4 and 5 GHz frequencies.

5. It is certified for interoperability with five devices

With the certification of 802.11ac Wave 2, the Wi-Fi Alliance listed five products that it has certified for interoperability:

1. Broadcom BCM94709R4366AC
2. Marvell Avastar 88W8964
3. MediaTek MT7615 AP Reference Design and MT6632 STA Reference Design
4. Qualcomm IPQ8065 802.11ac 4-stream Dual-band, Dual-concurrent Router
5. Quantenna QSR1000 4×4 802.11ac Wave 2 Chipset Family

6. It won’t be widely available immediately

Wi-Fi.org lists 24 products that have compatibility with 802.11ac Wave 2 features. However, not many of them are hardware-related. As with most new technologies, it will take some time for adoption to ramp up and for supporting products to be released. We will likely see more Wave 2-enabled hardware hit the market by the end of the year.

“You’ll see them in the devices in a near time frame, but the roll into the end-user, whether it be in the consumer or whether it be in the enterprise, it’s going to be a little bit slower,” Zimmerman said.

Google fiber is coming to your town. But not without a fight. After Louisville, Kentucky approved legislation that would allow Google Fiber to piggyback on pre-existing telecommunication infrastructure, AT&T sued the city.

“The ordinance in question, known as “One Touch Make Ready,” essentially allows Google (or any other ISP) to install its equipment on existing utility poles, including those owned and maintained by AT&T. Despite strong opposition from AT&T and Time Warner Cable, the ordinance passed with a 23-0 vote.”

AT&T claimed a need to defend past infrastructure investment, and that the ordinance violates current telecommunication rules. The city of Louisville countered claiming, “gigabit fiber is too important to our city’s future.” Google pledged to support the city.

Google Fiber Offering Super Fast Internet for $70 Per Month

Google officially became a service provider with the launch of Google Fiber, which will provide 1 gigabit Internet access and TV service.

“Google Fiber is 100 times faster than today’s average broadband. No more buffering. No more loading. No more waiting. Gigabit speeds will get rid of these pesky, archaic problems and open up new opportunities for the Web,” Google said in a blog post.

Initially, Google Fiber will only be available in Kansas City – Kansas and Missouri – and will only roll out after enough people in a given neighborhood sign up for the service.

Google today encouraged residents in the region to pre-register and get their neighbors to sign on, too. Pre-registration is $10 and is open until Sept. 9, at which point Google will see how many people have signed up and decide where Google Fiber will roll out. Neighborhoods need between 5-25 percent of homes to sign up for internet access in order for it to be cost effective, Google said.

Google is offering three service packages.

The Web-only Gigabit Internet plan is $70 per month and includes a network box with advanced Wi-Fi and 1TB of cloud storage. The selection includes a one-year service agreement, though you can waive that by paying the $300 installation fee.

With Gigabit + Google Fiber TV, Google promised hundreds of channels and on-demand shows, as well as 2TB of DVR storage and eight tuners. Subscribers will get a new Nexus 7 tablet, which will serve as a remote control. The package will cost $120 per month and include a two-year contract unless you pay the $300 construction fee.

A list of available TV channels is on the Google Fiber website and they include Viacom channels like MTV, BET, Nickelodeon, and Comedy Central. Missing at this point are Disney-owned channels like ESPN, the Disney Channel, and ABC Family, so Google has likely not secured a deal with Disney just yet. Premium channels like Showtime and Starz are on the list, but HBO and Cinemax are not.

“This channel lineup is only a representative lineup and is subject to change,” Google said in the fine print.

Google is also offering free Internet access to those who pay the $300 construction fee. Subscribers will get 5 Mbps Internet access at no monthly cost, though they can spread the $300 fee out over 12 months. Google promised that the free Internet option will be available for at least seven years.

None of the plans include data caps, Google said.

What if you have a service issue? Google said its customer support line will be open from 8 a.m. to 11 p.m. CST on weekdays and from 9 a.m. to 5 p.m. on weekends. The company also has a “Fiber Space” in Kansas City, MO. where customers can speak with a Google Fiber team member, but it’s unclear if Google Fiber technicians would be on call like other U.S. cable providers.

Google expects to have fiber connections built to the top 50 percent of “fiberhoods” by mid-2013. After Sept. 9, the company will publish a calendar with an estimated construction order.

Google first announced that it would develop ultra high-speed broadband networks back in Feb. 2010. At the time, it promised fiber-to-the-home (FTTH) connections that are “100 times faster than what most Americans have access to today.” By March 2011, Google selected Kansas City for its first network, and earlier this year there were rumors that the search giant would also be offering TV service.

In a statement, FCC chairman Julius Genachowski championed Google Fiber. “Abundance in broadband speeds and capacity – moving from megabits to gigabits – will unleash breakthrough innovations in healthcare, education, business services, and more,” he said. “Today’s announcement by Google, the Gig.U projects across the country, and similar continued advances by providers and municipalities are important and welcome developments that are pushing frontiers in speed and bandwidth, while also enhancing consumer choice.”
