It’s the network, stupid

Enterprise IoT Deployments require a bottoms up approach to be successful

James Carville, famed campaign strategist for Bill Clinton
in 1992, facing an incumbent President with a post-Gulf War approval rating of
90%, a year and a half before the election, coined the phrase, “the economy,
stupid”, to remind all staffers to concentrate on the importance of economic
issues.  It was short, pointed and
effective.  Similarly, when I look at
enterprises trying to deploy IoT networks, too many are focusing on a specific
use case or some payoff from big data, when they must remember, all successful
IoT deployments starts with the network.

Network

Enterprise IoT deployments need a bottoms up approach

First, some definitions:

  • Bottoms up = build wireless network (Wi-Fi +
    IoT).  Stable, scalable, secure – then
    build solutions on top of it
  • Top down = find a solution to focused
    problem.  Create an overlay network to
    connect app to a “thing”. 

Every house needs a solid foundation.  You would not want your electrician pouring
concrete, nor would you want your brick layer to work on your plumbing.  So why do we feel comfortable with sensor,
device or manufacturers of “things” providing the components for an enterprise network?  We shouldn’t. 
Thing vendors make things, and network vendors make networks. In
addition, each device vendor only cares about their own device, which means
their own network. Deploying a network for one device type adds complexity,
adds cost, is highly redundant and has the potential to create security
holes. 

Benefits of a bottoms up network

Just as James Carville beseeched his staffers to focus on the economy as a primary driver for success, so to do I beseech Enterprise IT and OT managers to think about the network first.  It will serve you well and provide significant benefits. And here are things to consider in making make a stable, scalable, secure, cost-effective IoT access network that can meet the needs of an enterprise IoT ecosystem.

Ruckus talks 5G and IoT at MWC 2019

The Ruckus Room recently caught up with Ruckus CTO Mehmet Yavuz and Ruckus VP Greg Beach on the sidelines of a very busy MWC 2019 to discuss 5G and the IoT.

5G

As
Yavuz tells The Ruckus Room, 5G is an
extremely hot topic at the conference in Barcelona. While enhanced mobile
broadband is certainly something to look forward to, says Yavuz, the deployment
of 5G also brings its own set of very real challenges, particularly since 80%
of mobile data is consumed indoors.

“The traditional cellular deployment model has big macros outside with outdoor
antennas. This is a really good model for wide-area outdoor coverage. However, 5G
uses the spectrum band – at the higher end of the spectrum at 3.5 gigahertz or even
higher,” he explains.

“[This makes it] difficult for the signal to penetrate indoors. So, you really need an indoor solution [such as CBRS private LTE] to help solve these indoor data demands. The indoor solution also needs to be scalable, low-cost and easy to deploy.”

Another important aspect of 5G, says Yavuz, is its expected ability to support mission-critical applications.

“You hear about ultra-reliable low latency or millisecond latency and these are targeted at high-end applications,” he elaborates. “It may be a venue [with a need to support] AR/VR, or it may be a factory [supporting] automation. [These applications] all require edge compute capabilities because you don’t have the luxury of using traditional mobile core networks ”

Yavuz also touched on the IoT, noting that there are a plethora of available technologies on the market today.

“We bring all these [disparate] technologies together under one umbrella with our Ruckus IoT suite,” he says. “For the IT department or the operational department, this means there is only one network to manage. For us, what is really important is simplicity, performance and the complete solution.”

Overall, notes Yavuz, the picture for 2019 and beyond looks quite exciting.

“We have all these great technologies coming together with our partners. We’re bringing all these great applications …

The Evolution of Wi-Fi 6: Part 5

In part four of this series, we explored a range of Wi-Fi 6 (802.11ax) features, including target wake time (TWT), 1024-QAM and Long OFDM Signal. In this blog post, we’ll take a closer look at the benefits of Wi-Fi 6 (802.11ax) for new and legacy devices, as well as the expected feature set arriving in Wi-Fi 6 (802.11ax) Wave 1 and Wave 2.

Wi-Fi 6

Wi-Fi 6: Current and legacy devices

Although there are relatively few Wi-Fi 6 devices (802.11ax) on the market today (90% of the devices of are still Wi-Fi 5), it is important to note that the industry faced a similar situation when Wi-Fi 5 (802.11ac) was first introduced. From our perspective, there are several reasons to begin moving to Wi-Fi 6 (802.11ax) as soon as possible.

Firstly, a Wi-Fi 6 access point (AP) can serve new Wi-Fi 6 (802.11ax) devices, along with legacy Wi-Fi 5 (802.11ac) and Wi-Fi 4 (802.11n) devices. Secondly, a number of manufacturers are already selling Wi-Fi 6 (802.11ax) clients. Thirdly, Wi-Fi 6 (802.11ac) and legacy clients can co-exist just like Wi-Fi 5 (802.11ac) and Wi-Fi 4 (802.11n). Last, but certainly not least, both Wi-Fi 6 (802.11ax) and non-Wi-Fi 6 clients benefit from Wi-Fi 6 technologies.

For example, Wi-Fi 6 clients are more efficient, thereby freeing up more spectrum for Wi-Fi 5 (802.11ac) devices. This is perhaps analogous to a carpool lane, in which the first two lanes are for Wi-Fi 6 (802.11ax) devices. More specifically, let’s say 50% of the devices are Wi-Fi 5 (802.11ac) and 50% are Wi-Fi 6 (802.11ax). We put all the Wi-Fi 6 (802.11ax) devices in the carpool lane, allowing them to operate more efficiently. Concurrently, the remaining Wi-Fi 5 (802.11ac) clients benefit because we took half the cars from all the lanes – which frees up contention for the Wi-Fi 5 (802.11ac) devices.

This provides higher throughput and performance for
networks, with beacon intervals occurring every 100 milliseconds. So, how does
this work? Well, the AP ‘says’ that it will use …

New e-book links poor network access security to data breach risk

Ruckus has just published a new e-book titled “Seven Network Access Security Risks—and How They Can Lead to a Data Breach.” It focuses on faulty network access security as a risk area that can lead to data compromise. As the title implies, this e-book outlines seven distinct risk areas that IT organizations should be aware of, especially when it comes to providing connectivity for BYOD and guest users.

As detailed in a previous Ruckus blog, “What’s wrong with PSKs and MAC authentication for BYOD?”, default methods of network onboarding and authentication have serious security flaws that can leave you open to data compromise. These security holes get less attention that more high-profile threats like ransomware, but the dangers are still very real. Sometimes it’s the attack surface that you aren’t thinking about that attackers seek to exploit.   

Linking IT security risk
areas to the potential for a data breach

Sometimes the link between a threat vector and the risk of data
compromise is obvious. Keylogging malware tracks a user’s every keystroke,
including when they type in their username and password for cloud-based
business applications. Email phishing attacks compromise credit card numbers or
other sensitive data by tricking users into entering them into a website that
spoofs a legitimate site. Misconfigured cloud storage can leave sensitive data
just hanging out there on the web for attackers to steal. All of those are
obvious ways that attackers can get at your data.

Network access security is a category where the linkages may
be less obvious. The point of the new e-book is to help clarify the connection
between this risk area and a potential breach. It’s a highly accessible way to
increase your knowledge of this often-overlooked area of the IT security domain—a
five-minute read covering an underestimated attack surface in modern IT
environments. This document can help you keep other stakeholders in your
organization informed about the risks as well, so feel free to pass it along. We
should emphasize that no registration is required to …

A New Age for Public Safety Video Surveillance

Video
surveillance is one of the most powerful tools law enforcement has in its
arsenal. It’s used to protect citizens and investigators, collect evidence, and
prevent crime. Unfortunately, law enforcement officials don’t always have the
lead time they need to set up equipment. While wireless IP video cameras help
facilitate rapid deployment, there’s still the legacy network infrastructure to
contend with. For that, law enforcement agencies need “pop-up” security enabled
by a solution that is cost-effective and easily deployed, virtually anywhere.

Video Survellance

The
development of IP-based video cameras gave law enforcement officials more
flexibility in terms of camera placement, but the network infrastructure
remained a barrier to achieving cost effective, rapid deployment. Wireless
connectivity over cellular networks like 4G LTE is simply too expensive. Plus,
it’s not unusual for service providers to throttle bandwidth, resulting in
performance issues. Other wireless solutions use a low bit rate at short range,
recording one frame every five seconds. While this may be suitable for
situational awareness, it doesn’t meet requirements for investigative cases
requiring real-time data.

Time
is of the essence during a criminal investigation. To benefit from video
surveillance in these scenarios, law enforcement agencies must be able to
quickly deploy video surveillance when and where it’s needed—without filing for
permits, installing fiber infrastructure, or incurring exorbitant fees. This
can be achieved with Ruckus Video Mesh Distribution.

Ruckus Video Mesh Distribution is an easily deployable surveillance network that delivers high bandwidth and full frame rate with low latency. Ruckus SmartMesh provides backhaul over a WiFi network, enabling law enforcement agencies to achieve visibility virtually anywhere there’s power—including locations where running copper or Fiber cable is unfeasible. The self-forming, self-healing, and self-optimizing technology makes mesh networking easy to deploy and manage.

Video Mesh Distribution…

  • Lowers installation and operating costs by reducing the need for Ethernet cabling and RF planning.
  • Delivers consistent bandwidth. Traffic is never throttled as it is with cellular providers.
  • Automates configuration, enabling Smart Mesh Networking WLANs to be deployed and operational in half the time of conventional WLANs.
  • Works

E-rate apocalypse?! Not so fast.

If you work for, or with schools and libraries you have most
certainly heard or asked the following questions over the past year:

“What will happen to E-rate next year?” or, “Will E-rate go back to the two-in-five-year rule?”

…and then of course there’s the gravest of questions, “Is E-rate going away?”

E-rate

Perhaps the easiest of these questions to answer is whether E-rate is “going away.”  Simply put, no. E-rate is a U.S. Federal subsidy program available to schools and libraries in support of deploying and maintaining affordable Broadband Internet access for instructional purposes.  Funding for this program continues to be collected today, as it has since its inception in 1996 via the Universal Service Fee on every U.S. phone bill. Despite changes to the oversight of this fund from the Universal Service Administrative Company (USAC) to the U.S. Treasury, assurances remain that this funding will not be reappropriated. Short of an act of Congress, the money is there.

In the absence of clear and concise guidance from the FCC
& USAC (nothing about E-rate is clear and concise) on potential changes to
the program, we can certainly read the proverbial tea leaves and arrive at some
relatively confident assumptions until more information is released. I base my
conclusions on what we know about the E-rate program historically, a recent
report published by the FCC and recent conversations with FCC & USAC
officials.

Let’s try and understand a little more about the current E-rate
program and what is at stake. In December of 2014, the same month I started at
Ruckus, the FCC issued its “Second
E-rate Modernization Order
.” This order detailed the commission’s
intent to improve performance and achieve the program’s goals of increasing
broadband access (Internet) in schools and libraries, particularly where such
access is limited. The initiative is subsidized based on level of need (Free
& Reduced Lunch) and student population (~$150 per student).  This is a relatively crude summary, although
it should provide a 100,000 foot “blog” view. 

One of the biggest changes was …

In part three of this series, we took an in-depth look at OFDMA, MU-MIMO and BSS Coloring. In this blog post, we’ll explore target wake time (TWT), 1024-QAM and Long OFDM Signal.

Wi-Fi 6

Target Wake Time (TWT) and Wi-Fi 6

Target wake time (TWT) is another mechanism introduced in the Wi-Fi 6 (802.11x) standard. Essentially, TWT allows devices to deterministically negotiate when and how often they wake up to send or receive data. TWT increases device sleep time and in turn, substantially improves battery life, a feature that is especially important for IoT devices. In addition to saving power on the client device side, TWT enables wireless access points (APs) and devices to negotiate and find specific times to access the medium. This helps optimize spectral efficiency by reducing contention and overlap between users.

1024-QAM & the Need for Speed

Although bolstering spectral efficiency is one of the defining features of Wi-Fi 6 (802.11ax), an additional speed boost facilitated by 1024-QAM is obviously a nice bonus. Quadrature amplitude modulation, or QAM, uses both phase and amplitude of an RF signal to represent data bits. As we mentioned above, Wi-Fi 6 (802.11ax) introduces 1024-QAM, along with new modulation and coding schemes (MCS). These define higher data rates that bolster throughput and enable 25% higher capacity with 10 bits per symbol versus 8 bits in 256-QAM, the latter of which is supported by Wi-Fi 5 (802.11ac). Put simply, more bits equal more data, making the (payload) delivery of data more efficient.

Wi-Fi 6 (802.11ax) also introduces two new modulation coding schemes: MCS 10 and MCS 11. Both will likely be optional. It should be noted that 1024-QAM can only be used with 242 subcarrier resource units (RUs) or larger. This means that at least a full 20 MHz channel will be required for 1024-QAM.

5G is great, but for the enterprise?

As we gird our loins for the annual pilgrimage to Mobile World Congress, I have a pretty good idea what to expect when we get there: Sweeping statements and predictions about how 5G is NOW and it’s is going to change everyone’s world forever!

To which I say, “easy, cowboy!”

5G

Now, don’t get me wrong: 5G New Radio (NR) promises to be transformational in many ways and we at Ruckus expect to be part of that transformation. But, as we see it, 5G NR technology will be only one part of a much more colorful tapestry, especially in the enterprise. We now find ourselves at the beginning of an age in which a plethora of ultra-capable wireless protocols will coexist and complement one another. Wireless Avengers, if you will.

This is what the ‘5G era’ is all about.

Nowhere is this new ear more in evidence than in the enterprise, where the WLAN and Wi-Fi are synonymous. These technologies have been optimized for the enterprise (and service providers!) for 15+ years by vendors like Ruckus. And, with the latest Wi-Fi 6 iteration (see: Ruckus R730), Wi-Fi is shockingly capable, with Gbps data rates, millisecond latency and even some DNA spliced from its LTE cousin. But make no mistake: The all-wireless office is being built today, with Wi-Fi. And it will be built tomorrow, with Wi-Fi.

Now,
if you walk down the hallway (or cross the courtyard) to Operations, what we’ve
found is that organizations of every stripe are seeking to reduce OpEx by, for
example, increasing their energy efficiency. They’re deploying networks based
on low-power protocols like Zigbee and BLE for condition monitoring: Lighting,
temperature, moisture, occupancy detection. And for safety: Connected entry,
panic buttons, and fall detection. Subliminal message alert: What if they
didn’t need to deploy stand-alone networks?

And,
there is another realm: The realm of the Critical. Use cases that are begging
for the right wireless enabler to let them flourish. Think reliable staff
communications. Think automated guided vehicles. Think nomadic transaction
kiosks. Think IP …
