Flooding and large rockslides in Glenwood Canyon in 2021 reduce fiber optic traces and created a communications nightmare for the Colorado Division of Transportation, making it laborious to remain in contact and share knowledge with crews as they labored on the emergency response and afterward repairs.
And day-after-day, alongside lengthy stretches of Colorado highways, mobile service will be spotty or nonexistent, inflicting staff and automobiles to vanish off the radar display screen. For a snowplow driver navigating an remoted highway in a blizzard, it may be the equal of a pilot dropping all contact with the management tower in a thunderstorm. Nobody would hear a misery name.
Since final fall, the division has been testing a South Korean communications expertise, provided via a Denver startup known as Eucast World, alongside a problematic four-mile stretch of freeway from the Bakerville to Silver Plume exits, east of the Eisenhower Tunnel, the place the terrain makes it tough for mobile indicators.
“The take a look at outcomes had been superb and really spectacular,” stated Bob Fifer, deputy director of operations at CDOT. “We went from zero mobile providers to a full sign with video streaming, calling, speaking.”
Eucast containers are comparatively small and the assessments proved they had been climate resistant. They hooked up to current gentle poles, drawing on the close by energy provide. As soon as powered, they connect with close by mobile or satellite tv for pc networks or faucet into fiber optic traces and may deal with about 200 gadgets. However their actual energy is available in utilizing a spectrum the FCC not too long ago opened up for public use known as Residents Band Radio Service or CBRS.
“We have now recognized a expertise that’s quicker, extra environment friendly and cheaper,” stated Gary Sumihiro, a world commerce marketing consultant who got here throughout the expertise whereas in Asia. Eucast World has the rights to deploy the expertise to the Americas and Europe, and is beginning with Colorado. The purpose is to finally manufacture the gadgets domestically.
By dropping a second SIM card into its gadgets, whether or not within the arms of an worker or mounted on tools, CDOT can talk on a safe and personal community with none extra month-to-month service prices. And since the containers can talk with one another, CDOT doesn’t need to run fiber to every location.
“We’re doing one final take a look at. I’m having my expertise staff set up a digicam on a wi-fi mobile modem,” Fifer stated. The purpose is to see how properly the Eucast containers can dwell stream video, one thing CDOT has struggled with as a result of wi-fi suppliers don’t need their bandwidth hogged up by dwell feeds, particularly in areas with restricted mobile tower protection.
Many cameras on COTrip.org present a static image relatively than a continuing feed due to that limitation. Additionally, having cameras and message boards on a personal community permits for higher autonomy in relation to including or eradicating gadgets, avoiding a name to the mobile supplier to modify out gear. And personal networks are safer towards hacking, making it more durable for folks to take over freeway indicators and alter the message.
4 containers had been put in alongside I-70, greater than would usually be required, due to the tough terrain. College students from the College of Denver helped configure the system and conduct the assessments.
As a second act, CDOT desires to check the Eucast system in Colorado Springs, which is donating a number of cameras and message boards, about 80 gadgets in whole, to the state. Constructing fiber connections to the gadgets, which avoids pricey mobile payments and permits for dwell streaming, would run about $5 million, Fifer stated. Shopping for and putting in the mandatory variety of Eucast containers would run nearer to $200,000 in one-time prices.
Initially, Fifer stated Eucast may fill within the gaps the place mobile protection is spotty, however he envisions the potential to create a second community, liberating up cash to place again into highway upkeep and repairs. CDOT pays from $50 to $150 a month per gadget for a mobile plan. There are about 1,200 gadgets assigned to the upkeep groups and one other 3,000 related to automobiles. One other 2,000 plus cameras and message boards depend on mobile modems. All of it provides as much as one enormous invoice every month.
Chris Medina, a Eucast director and founding father of Clovity, stated the corporate is working to make sure CDOT gadgets, particularly older ones, can seamlessly swap between networks when a sign drops. Having a constant and quick communications community alongside state highways may open up many different potentialities, corresponding to utilizing synthetic intelligence techniques to watch what roadside sensors and digicam feeds are offering, alerting crews and altering board messages in a extra well timed means.
Medina stated Eucast can be retrofitting a Ford F-150 with one among its containers and knowledge uplink to the Iridium satellite tv for pc community. The truck may arrive on the scene of an emergency and rapidly hearth up a sturdy communications community, the sort of resolution CDOT wanted again in 2021 within the Glenwood Canyon.
