Teldat Use Cases

Railway service integrator

Challenge

Railway service integrators are increasingly asked for digitalization solutions that will boost their rail manufacturers’ competitiveness by enhancing passenger experience. This involves offering high quality and secure connectivity to many passengers every day, even if carriages are crowded.
High speed train passengers will appreciate an ‘A La Carte’ Wi-Fi service which streams live content while offering an extensive range of products. This connectivity must be achieved on fast moving trains; these can reach speeds of 310 km/h, sometimes traveling through areas with bad coverage. This means that ground to train communications must include satellite links to avoid loss of signal for passengers.

Solution

The Teldat H2-Rail router provides the multichannel ground to train communication and onboard connectivity required – while its reliability is assured through ruggedization, vibration protection, and all relevant rail certifications (EN 50155). 4G/LTE, and satellite communications are supported.
APR2044ax Access Points are available to extend Wi-Fi coverage throughout an entire train. They are ruggedized, and certified for temperature, vibration, and emissions.
With Teldat’s OLA functionality, different WAN links can be optimized and combined. Smart load balancing, advance monitoring, application continuity and IPSec security are also supported.

Why Teldat?

Teldat offers flexible solutions, with combinations of Wi-Fi, LTE, 4G, 5G and Satellite available. These are backed by extensive experience in solutions designed specifically for railway applications. Teldat’s strong capabilities are demonstrated by vast experience in rail projects.

Rail vehicle manufacturer

Challenge

Manufacturers seeking to install connectivity solutions which fulfill rolling stock digitalization objectives must comply with strict train standards during the manufacturing process.
Trains can have very different configurations and lengths, so the solution must offer connectivity under widely varying circumstances. In all cases though, this connectivity must cover both ground-to-train and onboard communications.
If possible, provision should be made for 5G as well as 4G/LTE ground to train communications, to assure the best possible performance and capacity. Satellite links should also be included to ensure signal continuity in poor coverage areas. Similarly, Wi-Fi 6 should be deployed on the train, to ensure dense passenger populations enjoy full-speed, secure connectivity.

Solution

Using Teldat equipment and solutions, manufacturers can comply with all relevant train standards, and accommodate any train length or configuration as required. The H2-Rail router is ruggedized, protected against vibrations, and certified, while providing all ground to train communications for secure coverage. Manufacturers can extend Wi-Fi coverage throughout the entire train, irrespective of its carriage count, by deploying APR2044ax Access Points. While being ruggedized and certified for temperature, vibration resistance and emissions, they offer Wi-Fi 6 communications for secure, high-speed coverage in crowded carriages.

Why Teldat?

Teldat’s solution, based on H2-Rail and APR2044ax hardware, is robust and can endure harsh conditions. The ring architecture and dual SIM ensure Internet connectivity even in the event of failure. Teldat devices reduce the client’s operational costs by providing preventive maintenance.

Proactive Maintenance and Vibration control

Challenge

Rolling stock doors, rails and other rail hardware need regular inspection and maintenance to avoid risk of failure. If they have a network connection, IoT sensors can be used for proactive maintenance. Susceptible items can be monitored remotely, with particular checks for abnormal vibration levels.
A data model can be used for an early warning system. This allows prediction of failures and reduces maintenance costs. Installation can be easy, even when retrofitting into existing rolling stock solutions.
It eliminates unnecessary field visits by technical teams, and avoids the need for corrective maintenance. As well as reducing maintenance costs, this approach can improve quality of service, and significantly improve customer satisfaction.

Solution

Teldat’s solution uses sensors that collect remote data from train doors and other locations, and sends it to their backend cloud-based be.IoT platform. It also uses GPS data for location awareness.
The be.IoT software backend automatically collects the sensor data, and analyses it using artificial intelligence (AI) and machine learning. The results are available on dashboards which show live data and historical trends.
The be.IoT platform also allows the operator to manage their devices optimally, and make better decisions. For example, technicians can focus on specific targets, to eliminate unnecessary activity and travel.

Why Teldat?

Teldat’s communications background allows them to set up remote monitoring systems for proactive maintenance. This facility is key to cost-effectively reducing downtime and providing an optimum quality of service.
The Teldat solution is also easy to deploy and manage.
