Can Constraints Drive Innovation?

Oren Binder


By: Oren Binder, Director – Service Provider Marketing


Demand for mobile connectivity is growing rapidly, and the required wireless spectrum is a finite resource. In 2015, the FCC took a groundbreaking new approach to spectrum allocation, establishing the new Citizens Broadband Radio Service (CBRS) for shared wireless broadband use of the 3550-3700 MHz band (3.5 GHz Band) in the U.S. You can read more about this straight from the FCC here.
Innovation band. Historic shift. Paradigm change. These are just a few of the superlatives used to describe the way the FCC chose to address the spectrum constraints with CBRS. Here at Ruckus we tend to agree. The promise of shared spectrum is to deliver the advantages of licensed LTE in performance without the vast associated spectrum costs. OpenG_Blog-01

At Ruckus we were really excited about the potential of this new spectrum allocation model and specifically with CBRS—see our OpenG announcement here. But we know that while the FCC took the first bold step, it will be up to the industry to make the innovation a reality.

And so, we worked with five other wireless technology leaders—Alphabet (Google’s parent company), Federated Wireless, Intel, Nokia and Qualcomm—and today together launched the official CBRS Alliance.

Our goal, in a nutshell, is to make LTE-based solutions in the CBRS band widely available. In order to achieve this, the Alliance has started the development efforts, is putting together a product certification program, and will soon start running LTE CBRS field trials. In parallel, we plan to expand our strong eco-system with more motivated entities that will continue to work together to achieve the organization’s goals.

There’s a New Cloud in Town



By: Wendy Stanton, Marketing Manager


Back in the day, we only thought of clouds as  big, white, fluffy objects in the sky that held a large collection of tiny droplets of water or ice crystals. When full, the clouds release those tiny droplets, known as rain. Obviously that kind of cloud still exists but that’s old news. For awhile now, there’s been a new type of Cloud in town, and instead of holding water, it holds data—lots of data!

Chromebooks, iPads, laptops and smart phones are just a few of the devices that teachers, administrators and students are using in the education sector, and they are expecting these smart devices to be continuously connected inside and outside the classroom. To keep students engaged and focused in this digital era, teachers are looking for ways to leverage smart devices in classroom learning. What is the key? A reliable and high performance wireless network. 6a00d8341ea9ee53ef01b7c87fee2c970b-320wi

But schools need more than that. Once they have that high-performance, always on Wi-Fi network—which presumably has access points (APs) sophisticated enough to handle the amount of data connectivity required in a busy educational environment—they need an easy way to manage it. One great way to ensure schools have the Wi-Fi they need with a simple, easy-to-manage interface for their time-strapped IT administrators is cloud-managed Wi-Fi, a.k.a. Ruckus Cloud Wi-Fi. Ruckus Cloud Wi-Fi is a new WLAN management-as-a-service that enables enterprises with limited IT resources to easily set-up, monitor and manage a high-performance multi-site WLAN of any size, without compromising on Wi-Fi performance.

Schools like the Minooka School District in Minooka, Illinois, are thrilled with its new addition of the Ruckus Cloud, with its easy set up and simple management. No more figuring out which AP isn’t working—the cloud is in control. And when it comes to the students and teachers—the IT staff is no longer dealing with a stack of help tickets—the Cloud and great Wi-Fi work perfectly together. Also enjoying its new Ruckus Cloud Wi-Fi is the Belleville School District. With its single interface and mobile app, the flexibility of being able to work from anywhere has made the IT team’s job so much easier.

Everybody’s talking about the new cloud in town—Ruckus Cloud.

Ruckus Cloud Wi-Fi Opens The Door To New Customer Applications



By: Devang Bhatt, Enterprise Product Marketing


It’s been an educational experience being a part of the Ruckus Cloud Wi-Fi early access program (EAP). Sixteen customers across 10 states were included in the program, which kicked off six months ago.

After ripping-and-replacing previous non-Ruckus WLAN infrastructure, customers were ecstatic when they discovered blazingly fast Wi-Fi in high-density scenarios and an intuitive management interface. Compared to previous installations, customers found they only needed to deploy approximately half the number of APs. 

Since Cloud Wi-Fi could easily support dozens of active devices and equal level of throughput per user it opened the door for scenarios that just weren’t possible before.

Immersive Learning

One such scenario involved using an augmented reality mobile app (Aurasma) to enable immersive learning experiences at a K-12 school. Over 90 students gathered at the library roaming with their smartphones taking pictures scattered around the building. The app converts static images into augmented reality sessions, which included interactive video streams.

Students were excited about learning and more engaged. And when it was time for a break, they could finally enjoy a smooth Pokémon Go experience!  Cloud_Blog

Accelerated Deployment

One of the biggest challenges associated with deploying large-scale distributed wireless networks is the time-to-deployment. It can take several weeks for physical installation, provisioning and configuration of APs, switches and firewalls. To avoid that challenge, a number of customers took advantage of Cloud Wi-Fi mobile app, which significantly reduced AP install and provisioning time to a matter of days or even hours.  

With its scan-and-deploy functionality, users were able to scan serial numbers of APs to the desired venue in rapid succession prior to physical installation. One customer in particular was able to install 7 APs/hour including physical installation time and cloud onboarding of APs.

Satisfied Guests  

Another successful customer application was at a large car dealership. The dealership noticed that customer satisfaction ratings were dropping significantly, and surveys indicated that the difficulty of signing on to the captive portal and inconsistent Wi-Fi connectivity was the culprit.

After replacing the wireless network with Cloud Wi-Fi APs across 11 dealerships, customers can now quickly sign-on to a captive portal and surf the web from anywhere in the dealership. The dealerships are already seeing improvement in customer satisfaction across locations.

In just a short time, Cloud Wi-Fi has enabled customers to take advantage of new applications and experiences beyond what they thought were possible.  The journey has just begun…stay tuned.

Wi-Fi and Cloud: A Pairing Worth the Wait, Like a Great Wine



By: Dan Rabinobitsj, COO


Remember Orson Welles quoting Paul Masson in the famous commercial? “We will sell no wine before it is time.” It is such a great line. If only he hadn’t crashed and burned later! But the notion remains strong. Some good things take a while to make. And that’s true for us at Ruckus.

Today, we announced the general availability of Ruckus Cloud Wi-Fi, which pairs our awesome Wi-Fi with the public cloud. Although Ruckus is not first-to-market, we’re confident that we are “best-to-market” for those lean IT organizations small and large that want an affordable, intuitive WLAN and don’t want to sacrifice performance to get it.

Two years ago, Ruckus introduced the Virtual SmartZone (vSZ) to address an important market segment and enable large scale sophisticated WLAN deployments without a physical controller appliance. Today vSZ is deployed by more than a thousand customers that are managing over a quarter of a million APs in aggregate. On the SOHO and SMB end of the scale, Ruckus provides the Xclaim and Unleashed product lines. Pairing_blog_OneAP

Now we’re introducing Cloud Wi-Fi—based on a public cloud architecture—to support organizations of all shapes and sizes, at any scale. It pairs the high performance of Ruckus APs with public cloud for simple set-up and management. As we were planning and designing, we knew the ideal cloud offering from Ruckus would have the following attributes:

  • Scale – we took the same virtualized controller architecture of vSZ and made it the foundation for our public cloud offering.
  • Simplicity – we interviewed dozens of customers and developed a user experience (UX) design so easy to use that an untrained technician can easily set up and manage even a sophisticated WLAN architecture.
  • Open extensibility – In our network functions virtualization (NFV)-inspired architecture, capabilities are added to the cloud platform in the form of virtual network functions (VNFs) that can be built using any software architecture or programming language, as long as they have the requisite APIs. So neither we nor third-party vendors need to start from scratch.

The result of this two-year journey is what we call the Ruckus Cloud. Today, we’ve made available Cloud Wi-Fi, the first service enabled by the Ruckus Cloud. But there is more to come. In the future, we intend to bring Brocade switches, OpenG and Cloudpath into this platform for complete integration.

With that, I’d like to toast a great new pairing – Ruckus high-performance Wi-Fi and the simplicity of cloud.

K-12 Wi-Fi: One AP Per Classroom, Is It Necessary?

Phal Nanda


By: Phal Nanda, Director Product Line Management


Is it even recommended? Better Wi-Fi depends on some key elements (1) static factors such as coverage area, materials used for constructions, and planning, (2) known dynamic factors such as typical devices per room (20 to 30 devices), apps used during classroom and online testing, as well as (3) unpredictable dynamic factors such as sticky clients, networking gear failures (a part of the network, APs, switches), recent configuration changes impacting service, etc. Let’s look at each of those parameters more closely and determine the reasoning behind whether or not one AP per classroom has merit.

First of all, let’s look at cost. More APs per classroom means more APs of course, but there is more. More wiring - sometimes wiring cost is as high or more than cost of APs - more PoE switches (to power the APs), and more subscriptions in the cloud or more licenses for your Wi-Fi controller. There is cost everywhere, and these additional costs can add up.

Alternatively, less APs usually require a pre-deployment RF planning (some cost) and smarter Wi-Fi technology that can handle both static and dynamic variability of the environment. BlogCloud_OneAP

K-12 class rooms are small – about 35ftx35ft (or 1,225 sq.ft.). Walls between classrooms can be anything from accordion room dividers to drywall to concrete - though most are wooden structures with studs and drywall separating linearly constructed U.S. elementary and middle school classrooms. Rooms themselves are quite open. RF propagation would have minimal impact in covering upwards of 60-90 feet or more. All of those without even considering the value some Wi-Fi vendors bring with their RF innovations (such as Beamflex, ChannelFly, etc.).

In the classroom, kids are typically given one device each, for mobile learning as well as online testing, and we can expect to have 30 devices active per classroom at any time (not to mention connected devices in a backpack, purse or on a wrist.) The most taxing online traffic would likely be downloading video streaming services (between 2-5Mbps) during e-learning sessions.

With the unpredictable network conditions , such as class time running late and more kids waiting outside who are now connected to the same APs. In addition,  all APs are designed for classrooms; auditoriums and cafeterias require “stadium-like” client density handling.

The overwhelming simplicity of cloud management has provided school’s IT teams with the dilemma: while some controller-based Wi-Fi technologies provide better RF, the simplicity of Cloud is a decent compromise.

What if they had a choice? The best Wi-Fi and cloud management, would result in half the number of APs needed per school district, half the number of cloud subscriptions to buy and renew, half the number of PoE switch ports needed, and half the cost of cabling, half as many devices to fail… you get the idea. All of those, without compromising on cloud simplicity? Would you try it? What would your district do with a ‘Wi-Fi tax refund’ this year?

Ms. Lo Goes to Washington



By: Laurie Falconer, Director of Integrated Communications


On Friday, Ruckus Wireless Business Unit CEO Selina Lo was in Washington, D.C. speaking alongside White House administrators and industry leaders at an event marking the launch of the Advanced Wireless Industry Consortium, a $400 million initiative announced by the Obama Administration and led by the National Science Foundation. In addition to Selina, speakers included FCC Chairman Tom Wheeler, Director of the Office of Science and Technology Policy Dr. John P. Holdren, National Science Foundation Assistant Director Dr. Jim Kurose and US Ignite Executive Director William Wallace.

While the event did not require a 24-hour filibuster, Selina spoke about the importance of public/private partnerships to provide city- and community-wide technology to improve citizens’ lives, not to mention business. Selina talked about the smart city installations Ruckus is involved in, including those in San Jose, Paris, Hamburg, Singapore, Ghandinagar (India) and Tshwane (South Africa), and how Wi-Fi is an affordable public wireless technology capable of operating at speeds of up to a gigabit per second. White-House

Highlighting the biggest challenge as dependability (or lack thereof) in radio-frequency challenged environments, which characterize most urban communities, Selina shared the history of Ruckus aggressively going after this problem. Ruckus’ innovation in adaptive antenna technology has allowed the company to deliver optimum coverage and throughput in RF-challenged locations throughout the world. These include smart city deployments which are government funded, but increasingly, bankrolled by public/private partnerships.

Governments may provide right-of-way and power in exchange for giving their citizens and visitors free Wi-Fi access, while private enterprises might supply fiber, hardware, software and services in exchange for marketing promotion, analytics or the opportunity to sell other chargeable services. The ecosystem for the smart city industry is vast, including governments and policy makers, service providers, system integrators, applications developers, street furniture suppliers and owners, advertising companies, analytics companies, so on.

Highlighting that the work the NSF and US Ignite are doing will greatly ease the twists and turns for smart city researchers and entrepreneurs, Selina said, “I have personally benefitted from great research from our universities, access to venture capital, a vast network of people with experience and expertise I can draw on, as well as an ecosystem of companies that I can partner with. Along with federal R&D investment, our government’s innovative spectrum policy to provide more unlicensed spectrum access, and its support of programs such as US Ignite, will further fuel innovation and create new opportunities for entrepreneurs that dare to change our communities, our cities and our world.”

Having Trouble Keeping Up with the Pokémon Go Ruckus Without Wi-Fi? We’ve Got You Covered.


By: Sundar Sankaran, Chief Wireless Architect


You might have read about it in the newspaper. You might have heard about it on the radio. You might have watched the pundits exalt about the 25% surge in stock price. You might have event talked about it at the water cooler or come across the charts showing its explosive growth. But ultimately, you need to experience it for yourself to understand what all the hoopla is about. In fact, that chart doesn't even capture it all.  It is just a small fraction of the teenagers I saw earlier this evening near the Mountain View Library and City Hall -- almost every one of them staring intensely at their smartphone with occasional bursts of excitement and joy. They are on a mission to catch them all. On a mission to catch Pokémon. MtView

What attracts these pocket monsters to the Mountain View City Hall of all places, I wondered? And why are so many of the Pokéstops close to or inside these buildings? Is the adjacent park too wide open for them to hide? What is so special about that location? Then it dawned on me. All those monster busters -- Pokémon Goers -- needed Wi-Fi. The newest and fastest Wi-Fi. Now that Mountain View made the smart move to Ruckus, this helps teens catch them all and advance to the next level.

But let’s back up a bit. Looking into it a bit more, we found that Pokémon Go uses a combination of local Wi-Fi and GPS satellites. But because most of the game requires you to step outside, you often step away from a Wi-Fi connection and have to rely on using your cellular data. As a result, you can say goodbye to your data plan faster than you can say ‘Bulbasaur.’

The fact is that Pokémon Go is just the latest in a string of mobile apps to suck your data plan dry. In fact, it wasn’t that long ago that consumers were complaining about Snapchat’s heavy data consumption. Fortunately, mobile carriers are starting to recognize the need to keep up with their customers’ insatiable demand for data intensive applications and are adopting Smart Wi-Fi systems that make the process of connecting to Wi-Fi as easy as connecting to a 3G/4G service.

In the same vein, many cities across the U.S. today are implementing free public Wi-Fi networks, similar the one Ruckus deployed in Mountain View, as a way to attract more businesses into the community, increase tourism, enable new public services, and support internal city operations. The good news is that at the same time as cities are trying to benefit local businesses, they are also unintentionally benefitting your growing Pokédex.

Now go out into the world and keep throwing those Poké Balls!

The Theory of Wi-Fi Evolution and IEEE 802.11 Selection



By: Sundar Sankaran, Chief Wireless Architect


September 2015 marked the 25th anniversary of IEEE 802.11, commonly referred to as Wi-Fi. Over these 25 years, Wi-Fi has ascended from a technology that enabled computers to wirelessly transfer data at 2 Mbps to winning a spot in Maslow’s pyramid as the most basic human need.

IEEE 802.11 got here, as Lewis Carroll suggested, by running twice as fast. The standard has continuously advanced itself by introducing amendments, such as 802.11n, 802.11ac and 802.11ax. These amendments support higher data rates to meet ever-increasing application demands through the adoption of higher-order modulation schemes such as 64-, 256-, and 1024-QAM, by supporting channel bonding up to 160 MHz and by employing MIMO techniques to transmit multiple streams to single client. In addition to increasing the peak data rate, efforts have been made to improve the spectral efficiency, which characterizes how well the system uses the available spectrum (how many bits of data can be pumped per second in 1 Hz of spectrum). Multi-user techniques such as MU-MIMO and OFDMA have been introduced in 802.11ac and 802.11ax to improve spectral efficiency and network capacity.

The following table summarizes the key ingredients of various IEEE 802.11 amendments ranging from 802.11b to the recently ratified 802.11ac to the upcoming 802.11ax. As evident from this table, peak PHY data rate supported by IEEE 802.11 has gone up by a factor of 5000, and spectral efficiency has improved by a factor of 625. Enhancements like this have enabled Wi-Fi to become one of the basic needs of life on par with water, air and fire.

Cities Get Super with Ruckus




By: Wendy Stanton, Marketing Manager

What happened to the days of pay phone booths where Superman used to change his clothes, manual cash registers with the comforting “brrrring!” and parking lots where employees collected cash instead of automated pay machines? Those days are long gone. Remember watching the cartoon, The Jetsons, and thinking how great it would be to live in that era? Guess what? We’re there! Technology is not just in our homes, but throughout our communities. Smart Cities are popping up all over the globe, which employ new technologies that integrate urban infrastructure with powerful data analytics.

Relying on digital technology, Ruckus Wireless enables cities to become smart to help improve the quality of its citizen’s lives. By deploying broadband wireless connectivity, cities will attract more businesses to the community, increase tourism, enable a host of new public services and support municipal operations.

Delivering a Seamless Guest Experience



Author: Diana Shtil, Product Marketing Manager


The Hospitality Industry Technology Exposition and Conference (HITEC) 2016 took place in New Orleans last week, bringing together over 300 companies who all specialize in products, services, and solutions for the hospitality industry. From pay management systems, robots that deliver room service, and even high-resolution televisions, HITEC showcased true innovation that any hotel guest would wish to have. HITEC

So what is all the hype about? Isn’t a robot a little bit over the top? Well, HITEC and the broader hospitality community would argue no, it is just what is needed! Hotels are becoming an extension of the home and when traveling for a day or a month, customers want an unforgettable experience. A clean bed and mint on the pillow are no longer enough. Hoteliers are finding new ways of going above and beyond, whether it is shorter check-in times, additional in-room amenities, or personalized promotions.

Sure, not all hotels can afford to offer an unlimited amount of amenities, so it is key that they provide what all travelers are looking for. And this is food, shelter, electricity, and reliable Wi-Fi. When people are on the go, they carry multiple devices; a phone, tablet, and laptop to name a few. And they expect to connect seamlessly, especially when not at home. Hotels have to provide wireless connectivity that delivers reliable service despite interference from neighboring devices and high-density surges. ACCOR Hotels knew this challenge all to well, and partnered with Ruckus Wireless to deploy reliable connectivity at over 4,000 properties world-wide. It is more than just connecting your guests, but connecting with your guests to provide an unforgettable experience that makes them come back again and again.
