Winning Back the Weather Radio Channels Adds Capacity to 5GHz Wi-Fi Spectrum

In my last blog on 5 GHz spectrum, I discussed the recent FCC ruling that permitted outdoor access points to use the U-NII 1 band (5150-5250 MHz).

But the story doesn’t  stop there. As mentioned last time, there are significant technical challenges to using the 5 GHz band. It is not cleared spectrum. It contains incumbent uses that are important for national security and public safety. Therefore, it is imperative that Wi-Fi not create harmful interference to these incumbent systems. Cisco will not settle for less.

On the topic of interference, a particularly interesting component of the same  FCC ruling that opened the U-NII1 band for outdoor AP’s is that it also re-opened the Terminal Doppler Weather Radar (TDWR) band (channels 120, 124, 128) with new test requirements for DFS protection. Hold on, let’s backtrack a bit before diving into what this means:

What is TDWR?

In brief, Terminal Doppler Weather Radar (TDWR) “is a Doppler weather radar system used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the United States.” TDWR uses the frequency band from 5600-5650 MHz which is why wireless network equipment needs to be proven to “do no harm” to TDWR. If you’re curious for more information on TDWR, then please click here and/or here.

A Brief History

Many of you reading this will recall that the FCC closed the use of the TDWR band several years ago as the result of numerous reports of wireless equipment creating interference with TDWR. Read More »

Non-stop Wireless at Johns Hopkins Hospital

June 30, 2014 at 10:42 am PST

Johns Hopkins Medicine is one of the leading health-care providers in the US. The Johns Hopkins University School of Medicine is consistently ranked as one of the top Medical Schools in the US and the Johns Hopkins Hospital is consistently ranked #1 in the US for 21 years in a row! In a previous blog in 2012, we described how the Cisco Wireless LAN controller 7.5 release enables wireless networks to recover with no client re-authentication in the event of a primarily controller failure. In this blog, I will share more details about unified access deployment at the Johns Hopkins Hospital with particular focus on the High Availability design.

Industrial IP Advantage the IT and OT Broker

The IT (Information Technology) and the OT (Operational Technology) “worlds” are requiring convergence to meet the growing complexity of a more informed customer driven market. Not only in the technical sense, but also organizationally. 

I don’t know about you, but trying to keep up with the alphabet soup of acronymous in one world is difficult enough, but when we attempt to combine both “worlds” it can be  nauseating to say the least, and produce a terrible “soup” of acronyms   I mean both organizations speak different languages, right?  OEE, EOL, CNC, MTTR, EtherNet/IP, etc.. for OT, and  SNAP, OSPF,  EOF, NAT, IP etc.. for IT. The IT world is more formal too, right?  For example, IT SIP’s and OT umm ……..CIP’s.

Can you imagine the language and cultural challenges of both worlds trying to understand each others language let alone work jointly to execute programs and projects that drive business value for their company’s and markets?  I’ve heard in some organizations that proposition often times causes a bigger confrontation than the epic Ali vs. Frazier “Thrilla in Manila” battle, but it doesn’t have to be that way.  In fact, the Industrial IP Advantage website is an educational community of both IT and OT professionals. A IT and OT broker if you will.  You will find that the two worlds are not so different.IIPA Logo

 
Paul Brooks, Rockwell Automation; Dan McGrath, Panduit and Kevin Davenport of Cisco discuss how OT and IT professionals can leverage the Industrial IP Advantage community to accelerate the adoption of IP technology to converge both “worlds” and extract tangible value from the IoE opportunity.

The IT and OT worlds have more commonality than differences.  In fact, one of the common areas of focus for both worlds revolve around “standardization.”  Historically, OT technology projects and deployments have leveraged modified Ethernet implementations to connect machines, sensors and the like on plant floors.  This approached has produced many different flavors of industrial modified ethernet protocols, such as, ProfiNet, EtherCAT, Powerlink, etc.. Although these ethernet implementations allowed manufacturers to move further away from costly, difficult to maintain, and hard to scale proprietary technology the industry recognizes that a more universal standard technology approach is required to take advantage of the Internet of Everything (IoE) revolution and the 3.88 trillion dollar of manufacturing value associated with the IoE opportunity.  That standard technology foundation is Internet Protocol (IP).

By using the power of standard, unmodified Internet Protocol (IP) manufacturers finally have a universal technology platform that improves connectivity between people, partners and processes, devices, departments and systems in industrial applications, and opens up new opportunities for productivity, efficiency and flexibility. Industrial IP Advantage is an idea and resource to bridge the language and cultures barriers of IT and OT together and  drive the business and technical values required to meet the demands of the new consumer.

Please register for the community and join a growing community of your IT and OT peers who are innovating, learning and accelerating the adoption of IP to shorten their design cycles, drive supply chain agility, connect in more meaningful ways with customers and drive increased profit for their company.  In addition, you’ll have fun learning a new language.

14.4 Trillion (Reasons!!) To Visit Booth #1558 At 2013 CiscoLIve!

Last week I went to one of my favorite restaurants in San Francisco…. Swan Oyster.  It’s an old school “dive” with the authentic rustic ambience you would expect from a 100 year old SF oyster bar.  I waited in line for 2 HOURS for four reasons……well 3.8 reasons.  First, you can’t find fresher oysters anywhere, second; the smoked salmon on rye melts in your mouth and the 3.8th reason…. well, my mother in law loves it (that deserves more weight than 1 reason, so I gave 1.8)

So, why I’m a being a food critic at an event dedicated to IT, industrial and manufacturing professionals.  Well, I know you are constantly analyzing reasons to make the right decisions whether for your family, business or career. Even if they’re as mundane as determining if you should stand in line for 2 hours with you dear mother in law for a dozen oysters and a generous helping of smoked salmon on rye. So, I thought I would give you $14.4 Trillion (reasons!!!) to visit the IoT Pavilion (booth #1558) June 23-27 at Cisco Live in Orlando this year.

The Internet of Everything (IoE) will create opportunities to capture $14.4 trillion of value between 2013 – 2022.  Of which, $3.88 trillion (reasons!!) worth of value can be obtained from manufacturing and industrial industries.  That’s $3.88 trillion (reasons!!) of cost savings and revenue generation that can be realized by taking advantage of the IoE revolution!!!internet_of_things

What is IoE anyway?  Is it like the Y2000 hype…. absolutely not.

The Internet of Everything (IoE) connects people, processes, data, and things (IoT) to make networked connections more relevant and valuable than ever before creating new capabilities, richer experiences, and unprecedented economic opportunity.  IoE will be a disruptive force that radically transforms they way we create, build, deliver and experience every product and service we use today.

Every manufacturer will need to connect existing devices to the Internet for control monitoring, and intelligent decision analysis.  Previously unconnected devices will become smart objects and sensors connected seamlessly and securely throughout the enterprise. Applications that haven’t been identified will be created and enabled to drive operational excellence, improved asset utilization, supply chain agility, innovation, workforce productivity and increased customer satisfaction and acquisition.

The $14.4 trillion (reasons!!!) dwindle fairly quickly over time.  Manufacturers and industrial producers do not have long to develop and deploy the infrastructure required to take ADVANTAGE of the IoE revolution.  The challenge is that many of the things (IoT) deployed in industrial environments were built for very specific purposes, and due to lack of standards were developed with their own proprietary protocols.

These approaches and strategies produce highly complex and costly infrastructures that do not scale or provide the flexibility to capture the $14.4 trillion value form IoE.

But there’s good news…….
