Finally, we hope to have the opportunity to welcome Mass Transit readers and staff aboard our transit system next year. Coming to the Twin Cities in 2014: The Community Transportation EXPO in June and the Rail~Volution Conference in September.

In 2014, we will focus on our Fluidity Wireless Technology to deliver broadband connectivity to mass transit vehicles as an alternative to cellular or satellite communication. Fluidity is a vehicle-to-ground wireless communication system capable of providing up to 100 Mbps up to 220 Mph in a seamless fashion. It can be integrated with any on-board system and used for multiple applications such as passenger Wi-Fi, CCTV live video monitoring and offload, digital signage and CBTC. Our goal is to resolve the current connectivity challenges affecting many transit agencies around the world.
Fluidity is composed of an on-board network, a trackside network and a backbone. Having a good data backbone along a train is a challenge and many trains are still using mechanical couplers that offer very limited throughput. Having the capability to create a wireless network between cars simplifies the on-board system.
The trackside network is the main infrastructure of a vehicle-to-ground communication system. It can send data along the track and provide connectivity to the vehicles. The spacing of the trackside radios is now between one to three miles.
The last piece is the backbone to the trackside radios. In most cases, this is done with fiber or a combination of wireless and fiber. Although this can seem a daunting task, with the rollout of PTC, a lot of the infrastructure is already being put in place thus facilitating the deployment of this technology. Many of the on-board systems are capable of switching between different transmission systems as needed.
