Minding the mines

Nothing says happy customer quite like repeat purchases. Recently, ABB Tropos Wireless Communication Systems installed a wireless mesh network at PotashCorp – White Springs’ 100,000-acre phosphate mine in White Springs, FL. A previously deployed Tropos network is being used to improve safety and productivity at PotashCorp – Aurora. Repeat purchase, happy customer.

Wireless communication networks are not usually the first things that come to mind when people think about open pit mines. They generally envision large pieces of equipment unearthing and moving huge quantities of ore, rock, phosphates and other minerals. However, there’s a largely unseen but critical component of mine operations – digital technology, including communication networks, that helps keep mine operations efficient and safe.

What does this digital technology do? Here are some examples of applications enabled by robust, high throughput, low latency networks:
  • Video monitoring: Real-time, remote video allows for analysis of the amount of material being mined and aids operations in deploying trucks for transporting material from the pit to the processing plant. Also, the ability to monitor real-time video remotely enables managers to ensure that safety protocols are being followed.
  • Remote performance monitoring: The communication network quickly transports telemetry data from mining and process equipment, such as draglines and other in-pit equipment, to the facility’s operations center in real time. This allows mine operators to gather critical operational data in order to recommend scheduled equipment maintenance - vastly increasing efficiency, equipment uptime and worker safety.
  • Mineral analysis data: Fast access to mineral (phosphate, in the case of PotashCorp – White Springs and PotashCorp – Aurora) analysis data provides visibility into trends related to production issues enabling proactively problem resolution.
In the case of PotashCorp – White Springs and PotashCorp – Aurora, plant managers wanted to achieve near real-time access to data and video from the mining pit, in the pit trailer and the processing plants, in order to improve operational efficiency and safety. Their Tropos wireless mesh networks enabled them to achieve their goals.

Phoenix’s Tropos wireless mesh network: Easy to install, easy to operate and easy on the wallet too!

At ABB Tropos, it’s a point of pride that our wireless mesh routers are easy to install. Our customers agree.
“The Tropos routers are very easy to install – I can send someone out with a screwdriver and a node.  Once installed and powered, nodes just immediately associate with the network and are hands-off.”

But there’s more to ease of installation than just hanging the radios. There’s also a software component.

Like many customers deploying broadband outdoor wireless networks, the City of Phoenix’s Street Transportation Department built out their Tropos wireless mesh network over a number of years.

During that period, technology advanced. The initial rollout of the Tropos wireless mesh network in Phoenix in 2010 included 420 Tropos 5320 and 5310 radios and covered 250 square miles. As the network expanded to its current 500 square miles and 902 Tropos routers, the City mixed in newer model Tropos 7320 and 6320 outdoor wireless mesh routers. Because all Tropos routers use Tropos Mesh OS as their network operating system, routers originally deployed continue to operate and mesh seamlessly with the newer Tropos mesh routers.

Tropos Mesh OS is also key to the network’s ease of operation. As George Frangos pointed out in his quote above, newly installed Tropos wireless mesh routers automatically associate with the network and are hands-off from that point on. Further, because Tropos Mesh OS leverages multiple paths, RF channels and frequency bands, it automatically routes interference and other network faults, it’s enabled the Phoenix network to achieve 99.999% availability since its installation in 2010. And it’s done so without taxing the City’s IT staff.

As the wireless mesh network was rolled out, the City gradually retired the leased T-1 lines that connected traffic signals to the city’s centralized traffic management system. With first phase replacement of leased lines resulted in saving of more than $220,000 annually. As the network expanded, that savings grew to the current $400,000 annually. And that’s easy on the City’s (and taxpayers’) wallets.

To learn more about the applications and benefits of the Tropos wireless mesh network used by the City of Phoenix’s Street Transportation Department, check out our new Phoenix case study.

Tropos: from rugged to extremely rugged

Tropos mesh routers have always been rugged. For example, the only Tropos router in the New Orleans video surveillance network that was lost during Hurricane Katrina was one mounted to a pole felled by the storm. When power was restored, the network became operational. By itself. And, as one observer put it:
The [Tropos] mesh network allowed the city to conduct 110,000 home inspections in just 6 weeks, and to issue 500 building permits per day (a 500% increase). It also enabled free public Internet access that supported the businesses and employees returning to their homes and office. And of course, the system continued to serve its original purpose as a NOPD network and "security canopy."

Now, with the introduction of the Tropos XA product family for extreme applications, Tropos mesh routers have gone from rugged to extremely rugged. The new Tropos 7320-XA outdoor mesh router can survive even higher winds and temperatures while offering even better resistance to salt fog corrosion than the Tropos 7320. For applications on the go, the new Tropos 4310-XA can survive even more extreme vibration than the Tropos 4310 while providing a weather-proof enclosure that is suitable for external as well as in-vehicle mounting.

Does this have value to our customers? You bet it does. As John J. Cruz, Jr., Strategic Planning and Operations Research Division Manager (SPORD) at Guam Power Authority (GPA), told us:
“A tropical climate and typhoons are facts of life on Guam. When a storm disrupts power, we need our communication network to keep operating so we can get the lights back on as soon as possible. ABB Tropos developed the unique features of the Tropos 7320-XA at GPA’s request to ensure that our wireless network functions reliably even in the face of the extreme conditions we occasionally face on our island. The survivability of Tropos networks through Katrina and other natural disasters is proof that GPA made the right choice.”

When developing the Tropos XA product family, we remembered our friends in the public safety and critical infrastructure markets. The Tropos 7329-XA and Tropos 4319-XA provide the features and benefits of the Tropos 7320-XA and Tropos 4310-XA, respectively, while offering connectivity in the 4.9 GHz band. The 4.9 GHz products are available only in the United States, where the 4.9 GHz spectrum is allocated for licensed use by public safety agencies and certain critical infrastructure operators.

Reboot: new web site = time to relaunch the Tropos blog

As you may have noticed on your way to this post, we did some pretty radical remodeling – both look and content – to Spurred by the one-year anniversary of our acquisition by ABB, we made a number of changes including:
  • Converting the website, as well as our literature and YouTube channel, to use the look and feel of ABB documents and web properties
  • Making it easier to get in touch with us by providing more places where you can fill out contact forms
  • Simplifying the process for gaining access to content requiring user registration  (e.g., white papers and case studies) by asking only for an email address on our registration forms and providing a register-once, download-many registration system.
There’s lots of new and improved content on the Tropos web site, including the new Silicon Valley Power and Rock Hill case studies as well as the new Venice (yes, the one in Italy) success story. We invite you to peruse the site and give us your feedback on how we can improve your website visit experience. As we mentioned, finding a contact form is easier than ever.
Refreshing the web site also spurred us to reboot the Tropos blog (obviously). Check back often as we’ll be posting new content often. We promise. Also please follow @TroposNetworks on Twitter.
