In Part One of this series, we explained how recent advances in technology and standards have revolutionized reliability for industrial wireless applications; they are no longer the Achilles heel of signal transmission. Specifically, Parallel Redundancy Protocol (PRP) as defined by IEC 62439, is helping in this revolution as it greatly improves wireless network performance.

The improvements are dramatic. In practical tests, the perceptible packet loss for an application with PRP was reduced 500-fold! It is quite unbelievable – but true to the level of improvement you could realize in the field.

Now, let’s build on the gains from standardized PRP and look at two additional developments that make today’s wireless even more practical. These implementation options include frequency diversification and the integration of PRP right into wireless equipment.

Talk about buzz! When I was standing in line at Sbarro's to buy my lunchtime Stromboli at NAB, I heard people talking.

"Can you believe it? Belden bought Grass Valley."

"No way!" said the other guy. "You mean Grass Valley bought Belden, right?"

No, that old fuddy-duddy wire manufacturer, the one that has been churning out video cable (and 6000 other kinds), took all that money you spent (thank you very much) and bought Grass Valley. Now you can't say we didn't warn you. We've been buying lots of lots of other companies. You can thank John Stroup, our CEO, and our Acquisition Team. We bought Telecast, they do fiber in the broadcast space. Then we bought Miranda, a serious gear manufacturer.

Wireless is invisible. You can’t “see” the waves bathing the space in your home, so the number of devices on your network (or on your neighbor’s network), and the volume of transactions occurring, (even without your explicit command) might surprise you. With only the three main non-overlapping channels in the popular 2.4GHz band, the room can get crowded, even when you think you’re alone. There are two separate ways to verify the density and intensity of wireless network usage, and they are both something you should do at least once, because it will help you make some informed decisions.

After its introduction to the market in 2009, bend insensitive multimode fiber (BIMMF) received plenty of attention. But some might not realize that bend insensitive singlemode fiber (BI-SMF) actually came first.

Due to smaller cabinets and longer wavelengths used in outside plant (OSP) and passive optical network (PON) applications, BI-SMF was introduced in 2007 under the International Telecommunications Union (ITU) G.657 standard.

However, splicing ITU G.652D standard singlemode fiber to newer G.657 BI-SMF fiber can cause some confusion.

There’s no escaping the push to secure industrial applications. The end of support for Microsoft’s Windows XP operating system is just the latest situation that contributes to the need to make sure that industrial networks have cyber security measures in place.

The challenge is how to go about it. If you’re the person tasked with security—and if you're reading this, you probably are—the ambiguity surrounding security for industrial systems has probably struck you already.

One tool in the toolbox to help you improve the cyber resilience of your facility is to leverage the know-how of your company’s IT security experts. Before you start running for the hills at this suggestion, I hope you will read on and find out how this may actually help.

It was an exciting day at Belden as we had an opportunity to ring The Opening Bell at the New York Stock Exchange. Our President and CEO, John Stroup, led other members of our senior management team on the podium.

John was joined by Henk Derksen, our CFO, Kevin Bloomfield, general counsel, Michelle Long, senior VP, Tax, Jeremy Parks, VP, FP&A and treasurer, Brian Anderson, corporate attorney, Matt Tractenberg, VP, Investor Relations and Tim Lenze, investor relations analyst.

This effort was secured by our investor relations team as a way to shed light on some of our significant accomplishments over the past few years.

Ask yourself, “Is what I’m trying to do reasonable?” A lot of times, even a well-oiled high-performance wireless router just isn’t going to be able to do what you want, but it can be hard to know where the line is drawn. For instance, if you are trying to stream uncompressed, high definition (1080p) video to a large-screen TV, it can require a sustained bitrate of 25-50Mbps (Bluray/H.264/MPEG-4). Most routers claim at least 300Mbps speeds on the packaging, so that should be no problem, right? It turns out, though, that once error correction and normal household interference are factored in, the effective speed of that router paired with your set-top streamer or laptop is closer to a maximum of 30Mbps, and a steady-state of 15-20Mbps. This happens to be in the sweet spot for video with more compression, like DVD/H.262/MPEG-2. Lower quality video will look just fine on smaller screens, but softer-edged and less vivid on big displays. This is how YouTube and Netflix manage to run a perfectly acceptable video on your tablet with streaming rates around 1Mbps or less – on a tiny handheld screen you won’t notice that 98% of the information has been thrown away. On a 60” LED-backlit flat panel with surround sound it looks noticeably blocky and sounds crunchy. Advertising promises are mostly to blame for this mismatch of expectations, not the performance of your network. If you are doing something that needs high sustained rates, wire it.
