Gigabit Wi-Fi Enables Digital Learning Ecosystems

by Moderator a week ago - last edited a week ago

Paperless classrooms were once more of a dream than a reality. Not anymore. Just listen to how pervasive, reliable and secure Wi-Fi is transforming education at Woodland Joint Unified School District in Woodland, California.

 

“Five years ago I started attending conferences on technology and was frustrated to see all the things I could accomplish, but was unable to,” says Jerry Delsol, a high school science teacher with over 30 years of teaching experience.

 

“Now,” he continues, “our district has a robust and reliable wireless network. This has revolutionized my classroom by allowing me to build the digital ecosystem that I’ve envisioned. All of my students are able to participate wirelessly with our district-issued devices as well as their own smartphones, tablets and laptops.”

Classroom flipping is a hot topic among educators across the country, including at Derby Public Schools in Derby, Kansas. There, modern computing technologies are making flipped classrooms practical.

 

“I teach a paperless, modified flip class,” reports Laura Hayden, eighth-grade digital studies and yearbook teacher at the Derby Middle School. “It’s essential for my students to get to their online material quickly and our wireless system enables them to do just that. It’s significantly faster than our old wired network.”

Wi-Fi Mobilizes the Common Core

by Moderator 3 weeks ago - last edited 3 weeks ago

Springfield’s investment in wireless networking is essential to supporting all 21st Century educational models at the district. This includes the transition to the Common Core State Standards. “Educators and students are becoming more dependent on a wireless network for teaching and learning. So the role of our WLAN is becoming more important every day as teachers increasingly rely on technology to share content, engage their pupils and improve collaboration among students.”

Adding a Lane to Your Wi-Fi Commute

by Moderator a month ago - last edited 4 weeks ago

Have you ever sat in traffic and wished there was another lane? I’ve been making this wish a lot lately, as my commute seems to be getting longer each day. While sitting in traffic this morning I started thinking about what causes traffic congestion and I realized there are a number of parallels between traffic and RF engineering.

 

Whether you are talking about more cars on the road or more devices on the Wi-Fi network, traffic and RF engineers both need to figure out how to make the best use of a fixed resource.  I’m not sure about the life of a traffic engineer, but the life of an RF engineer got a lot better with the introduction of 802.11ac.

 

802.11ac brings gigabit speeds to Wi-Fi and doubles the channel width of 802.11n by allowing 80-MHz channels in 5 GHz. By doubling the channel width, you double the speed. Faster speeds mean devices take less airtime to receive the data, so you can support more devices on the network with less congestion.

 

Aruba maximizes this opportunity by supporting all five 80-MHz channels available in the U.S.  Whether you’re deploying 802.11ac in a large campus or a retail store, the ability to use all five channels reduces the performance-robbing effects of co-channel interference and maximizes channel re-use.

 

There are actually six 80-MHz channels available, but channels between 116 and 132 are used for weather radar, so the maximum available for Wi-Fi is five 80-MHz channels: 36E (36, 40, 44, 48), 52E (52, 56, 60, 64), 100E (100,104,108,112) and 132E (132,136,140,144) and 149E (149,153,157,161).

I was bit surprised that Cisco only recently started talking about radio management support for 80MHz channels and shocked when I found out that they don’t even support all available channels. I guess they don’t mind sitting in traffic. As you can see below, Cisco does not support 132E, since Channel 144 is missing.

 

 Cisco traffic.png

 

 

 

By supporting all five 80-MHz channels, Aruba has an immediate 25% performance advantage.

The next time you’re stuck in traffic, ask yourself how great life would be with that extra lane.

The IT Desk Formula for Microsoft Lync

by Moderator on ‎03-17-2014 11:38 PM - last edited Tuesday by Community Manager

People prefer making calls on cell phones. You may also be surprised to learn that water is wet and the Pope is Catholic.

 

When I ditched my house phone about eight years ago, it was because it rarely rang and when it did it was either an international call from my mother-in-law or a robocaller. Needless to say, I couldn’t ditch it fast enough.

 

My desk phone at work took a little longer to transition, but now it’s also on the way to becoming a relic of the past. Thankfully, my employer, Aruba Networks, just recently liberated me, removing my desk phone and offering me Microsoft Lync 2013 across all my devices.

Five new Wi-Fi technologies that mimic self-driving cars

Living in the Bay Area, it’s not unusual to see Google’s autonomous cars humming along sans driver on the commute to work.  Personally, I cringe at the thought of turning the wheel over to a robot. I’m even holding out on the move to an automatic transmission. But a recent car crash that may (or may not) have resulted from me taking off my car’s traction control had me thinking… robots are probably way better, safer, more law abiding drivers than us feeble humans. And the same can be said of networks. Let's take a look at five new technologies that Aruba is announcing today and how they bring the world of driverless cars to our Wi-Fi.

If you’ve read about #GenMobile, then you know that the appetite for connectivity – 69% of younger GenMobile employees want to connect at work via Wi-Fi.  So more than ever, business continuity relies on your Wi-Fi network being “always on.”

 

That’s why Aruba networks has ensured that even when our Aruba Central management service isn’t available, you can still run and manage your network.  If your WAN link goes down, or if your subscription expires, your Aruba access points still operate perfectly, and you retain network monitoring and configuration.

Free Market Radius

by Moderator on ‎01-09-2014 10:27 AM

Over the holiday period I helped my mother-in-law setup her new Aruba Gigabit Instant AP. A gift that allows me to stream Premier League soccer matches to my MacBook Air at the same time my kids are streaming videos from Netflix and playing Minecraft.

 

The installation could not have been easier.  The network consisted of a cable modem, 8-port Gigabit Netgear switch, and the new Aruba Gigabit Instant AP. Three different vendors and everything just worked. How come things aren’t this easy in enterprise networking? 

 

The industry is full of standards, but multivendor interoperability is always a challenge. This is due in part to a vendor’s ability to extend standards with specific attributes. A vendor’s economic philosophy and willingness to do what’s best for IT also plays a big part.

 

So when it comes to multivendor interoperability, I’m taking sides with Adam Smith and Vincent de Gournay and embracing free-markets. It’s a far better world for IT without coercive monopolies and markets devoid of competition.

 

Aruba employs a free-market approach for enterprise mobility and ClearPass is a perfect example. ClearPass offers innovations in policy definition, guest access, device onboarding, and certificate management.

 

While each innovation is unique, one of the biggest differentiators is its vendor independence. ClearPass can be deployed with any vendor’s wired, wireless or VPN products.

 

With over 100 built-in RADIUS dictionaries to support different vendor products, ClearPass eliminates the need for lengthy onsite professional services contracts and you don’t need to purchase any additional infrastructure.

 

Unlike Aruba, Cisco takes a closed-market approach with its Identity Services Engine. This approach is tied to a single-vendor-network philosophy without the necessary market pressures that fuel innovation and keep prices inline.

 

Cisco will claim it’s open and supports RADIUS, but it offers no built-in dictionaries to support third-party vendors. It also requires additional hardware, commonly referred to as “inline nodes,” if you have any third-party products in your network.

 

In addition to increasing costs, this introduces yet another layer of complexity in your network that needs to be managed. It’s simply a veiled attempt to lock enterprise IT into one vendor, exercise control over your buying decisions, and sell more networking gear.

 

And once you’re locked in, you’ll fall prey to the infamous Cisco Customer Loyalty Tax.

 

Whether you want to simply replace your end-of-life Cisco ACS servers or deploy a policy management system, ask yourself if you’re ready to put free-markets filled with innovation and freedom of choice on ISE.
