Whether on the front burner or back burner, implementing wireless for your industrial application is probably somewhere on your stove top. Before you simmer, boil or decide to toss the whole concoction out, I urge you to take another look.

Today's standard 802.11N wireless LAN technology is the technology tipping point that makes it stable, reliable, fast, and a lot easier to deploy in industrial applications.

To help you evaluate today’s industrial wireless, consider the following eight key points.

Industrial Wireless Uses Are Evolving

Wireless in our homes 10 years ago was rare. Today, most of us count on wireless for our computers, tablets, phones, and even music & television. In the same way, at one time, industrial wireless was only for “must have” applications like rotating equipment, overhead cranes or automatic guided vehicles.

Today, it’s moving rapidly from those few, critical “point” solutions to infrastructure-for-convenience. Wireless infrastructures are now much easier to deploy and provide very good reliability and flexibility, making it a great choice for mobile workers with notebook computers, tablets and other wireless tools.

With the right design & deployment, you’ll get the reliability, performance, and coverage needed to do important, even mission critical tasks including control. With the right application, you'll make an industrial wired & wireless infrastructure a must-have ingredient in your production space.

Exceptional Industrial Wireless Applications

Consider some of your company's biggest challenges. Wouldn’t a few of them be dramatically improved with a high-performance, stable, industrial wireless infrastructure supporting the right applications? Need more productivity? Let your workers take the control room with them as they address production needs wherever they are.

Worried about fewer domain experts? Let your onsite worker tie in your suppliers, customers and remote workers with 1-button access, live video, and easy access to machine status, drawings, and other critical data to support you better than ever before, albeit remotely.

Make it Industrial Wireless

For all the same reasons your controllers, drives, I/O and switches have industrially hardened ratings, make your industrial wireless choice be truly industrial. You may need to hold a quick intervention with your IT group. Explain that while air is the same everywhere, the location of wireless electronics require that the equipment have the same industrial ratings as other factory equipment to reliably transmit data.

As you move from dedicated purpose wireless to infrastructure, the temptation will be much greater to use commercial grade infrastructure equipment. However, think again about where the equipment will be located and be sure to talk to your IT group about your expectations.

New call-to-actionIndustrial Wireless Is Getting Easier

Factories and other industrial facilities have long been a challenge for wireless deployments. High powered electromechanical equipment, large metal objects and frequent movement makes wireless signals bounce, cancel, and do other strange things.

Today, you still need to do a site survey, and anticipate the additions and movements of equipment to correctly deploy wireless. The good news is that features such as MIMO (multiple-input and multiple-output) compensate for reflections.

The combination of

  • MIMO
  • 300-600Mbps speeds
  • and other features make wireless signals stronger instead of weaker, dramatically reduce dead spots, and increase performance and distances.

Further, today’s new technologies with improved filtering eliminate most of the electromechanical noise that used to provide for tricky, often unreliable operation.

It's Getting Easier Part 2

In the past, you needed special equipment and expertise for your site survey and again at installation. However the software used to manage industrial wireless infrastructures has improved dramatically. It is much easier for controls, process, and automation engineers to use.

It can show you what’s happening as soon as you turn your equipment on, giving you the ability to adjust, reposition, add or delete equipment to get the coverage you need with relatively little fuss.

Stability Makes it Mainstream

A funny thing happened during the writing of the Wireless N specification... they added a feature called retries, designed to resend any transmission of data that wasn’t received intact in its first try.

In the industrial space, retries has been included in industrial networks since the early 70s, but it had not been a part of previous IEEE-802.11a/b/g wireless products. Now part of the 802.11N standard, retries and improved signal filtering produces wireless capable of sending & receiving millions of packets without dropping any.

Security, For Better or Worse

In many ways, the security offered in today's wireless technology is significantly better than wired. The encryption offered, for example, is exceptional considering the many industrial Ethernet protocols that go unencrypted when travelling a wire.

Further, many of the security measures we recommend for wired networking are also available for wireless segments. On the flipside, a security issue that remains a concern isn't about intercepting and maliciously controlling wireless signals, but rather about interfering with the wireless signals to create a denial-of-service.

You’ll need to have good physical security in place for the facilities where your wireless operates, and you may need to take additional measures to minimize or avoid this risk if it is a concern for your application.

Consult the Industrial Wireless Pros

Whether you’re just getting started, considering a move from “must-have” to infrastructure, or ready to go wireless or bust, you’ll be well served by consulting with others who have already been where you’re going.

Since older experiences with wireless won’t be the same as current ones, talk to those who have kept pace with the technology & its deployment.

The fires are warm, so your chances for cooking up a wireless recipe for success are excellent!
