Within the rail industry, Icomera TraXside™ is a key component in delivering the next generation of mobile Internet connectivity, helping erase any “not spots” in connectivity by providing continuous, high-capacity bandwidth to a train along the entirety of its route.

The Challenge

Rail passengers and onboard systems increasingly expect and rely on fast, uninterrupted Internet connectivity for the duration of the train journey.

Business travellers wanting to use video-conferencing, leisure passengers wanting to stream their favourite TV, and security applications streaming live HD CCTV images to central operation centres are just some of the use-cases behind the need to deliver more bandwidth to the connected rail vehicle than ever before.

While the coverage and capacity of cellular networks is steadily improving, the scheduled network roll-outs are not currently keeping pace with the demand for the true “Gigabit Train” (a vehicle with a 1Gbit/s or better connection to the Internet.)

Next-generation technology, delivering the true Gigabit Train

Icomera TraXside is a powerful subsystem that interacts with Icomera’s onboard routers to provide a dedicated backbone, supplying Gigabit connectivity through dedicated infrastructure installed along the track and onboard. It delivers reliable track-focused coverage for Rail operators, helping provide continuous, high-capacity bandwidth to a train along the entirety of its route. Using the aggregated capacity of two simultaneous 3×3 MIMO radios, TraXside™ delivers a median real TCP/IP throughput of around 1 Gbit/s during train travel – unrivalled bandwidth for rail passengers and onboard systems.

Icomera’s modular, technologically-flexible approach allows its mobile Internet connectivity solutions to seamlessly integrate and aggregate the capacity of all available communication networks in parallel, offering maximum coverage and capacity. 3G, LTE, LTE-A, 5G, TraXside and even satellite networks can all be utilised as part of a single solution.

  • Infill cellular “not-spots” over- and underground and in tunnels
  • Reduce mobile data costs along the busiest areas of the rail network
  • Seamless hand-over between Icomera TraXside and cellular networks

The extreme high performance of Icomera TraXside, especially the distance between base stations, significantly reduces the CAPEX required to deliver the solution to underground or overground rail systems. Icomera TraXside is part of Icomera’s industry-leading X-Series Platform for connected vehicles. Icomera delivers Internet connectivity for millions of passengers and thousands of vehicles every day. The X-Series Platform includes Icomera’s remote central configuration, reporting and monitoring tools for robust and best-in-class asset management.

How does TraXside work?

Icomera TraXside supplies a dedicated highspeed radio network along the railway track using the 5 GHz band. The TraXside Unit can be set in either Base Station Mode (on the mast) or Onboard Mode (on the train).

Each mast has a TraXside Unit in Base Station Mode attached to it, which sends and receives data from the train using a 5 GHz radio. This Unit communicates with the TraXside Unit in Onboard Mode on the train, which in turn communicates with the onboard X-Series router to the passenger. Each Base Station unit has two channels, Channel A and Channel B, which send and receive signals to the train as it travels along the track.

Icomera’s turn-key TraXside solution includes radio planning, system design, installation, commissioning and optimisation. The masts are adequately spaced apart so as to ensure that wherever the train travels, it is always within at least one channel’s range (ideally two), and so that the system provides the minimum throughput as per the design criteria.

No handover delay or packet loss is experienced since the train is connected to at least one channel at all times, and often two. This means that the transition between signal sources will be seamless.

The Connected Journey

Icomera believes in a better future powered by a Connected Journey: A revolution in transport powered by high-performance wireless Internet and a range of services that run seamlessly through this connectivity.

The Icomera Way

The Icomera Way is what we do and how we do it. It’s what makes us different and gives us our competitive edge. The Icomera Way is based on three elements that combine to deliver the best platform, best connection and best solution on the market. It is this base that allows us to deliver The Connected Journey.
