A 10 G Network Upgrade Changes the Large Urban Transportation Network’s Landscape

The Evolving Needs of Modern Transportation Systems

In the early 2000s, an urban center in the U.S. Pacific Northwest was one of the first early adopters of Intelligent Transportation Systems (ITS) to implement the collection, transmission, and application of real-time traffic data and other related information. As the ITS expanded to monitor and manage nearly 100 road intersections, equipment from four different was necessary to incorporate overtime. This made the system more challenging to maintain, as there were four unique configuration methods. As the system bandwidth increased, traffic engineers in the Traffic Management Center (TMC) noticed “screen tearing” on the video feed from the system’s IP cameras. The network with a maximum transmission speed of 1 gigabit (1G) needed an upgrade to 10 gigabits (10G).

Constrained Optimization in 3 Areas

Three crucial areas face challenges:

  • Size: Due to space constraints, the deployment required a compact 10 G DIN rail solution.
  • Speed: The city planners demanded a solution that could be quickly implemented – fast implementation and response times were of utmost importance.
  • Power: Support for the latest PoE (Power over Ethernet) standard was required so all existing and future devices that need to draw power from the network would function smoothly.

Matching Challenges With the Best Solutions

The old 1G switches in the city’s ITS were replaced with EtherWAN’s EX78900X hardened managed 12-port gigabit PoE and 4-Port 10G SFP+ Ethernet switches. In addition to 10 G and a 90-watt PoE, the EX78900X provides additional features that offer more flexibility and control. These include PoE auto-recovery, built-in digital inputs, and a host of security features to prevent digital intrusions.

The upgrade proceeded quickly and smoothly, with no need for existing network topology changes. The benefits of the improved 10 G speed were immediately apparent. The ability to deliver 90 watts of PoE, along with a robust 360-watt power budget, allows the EX78900X to power all existing IP cameras and future PoE end device installations with higher power requirements.

EtherWAN provided comprehensive sales and technical support, as well as extensive product training for EX78900X’s special hardware and software features. Our objective was to ensure that EtherWAN would be able to respond swiftly to all ITS and procurement management inquiries to drive the efficiency of this large-scale project upgrade.


Unleash ITS’s Future Possibilities

As 90-watt PoE and 10G become mainstream, hardened devices that support both technologies will see broader ITS adoption in cities around the world. For both new installations and upgrades, communication and teamwork between sales managers, traffic partners, and field sales engineers are crucial to fast and economical implementation of these next-generation technologies.
