“The cost vs performance ratio has proved outstanding. Combined with the reliability of the equipment and the generous warranty terms, it is clear we made the right choice by selecting RACOM and RAy microwave units.”

DPL now considers RAy a core element of its strategy – enabling stable, high-quality connectivity across Lebanon.

How do you deliver real-time split-time data for a world-class ski marathon across 15 km of mountainous terrain – during a day when public mobile networks collapse under the load of thousands of spectators? For the timing specialists at On Line System, the answer was RipEX.

Spectators see split times live on big screens and TV broadcasts, but few realise the technical obstacles behind them – especially in large outdoor events such as:

• long-distance cross-country skiing
• mass running events
• cycling marathons
• orienteering
• triathlons

For Jizerská 50, part of the Visma Ski Classics series with nearly 5,000 competitors, reliable split-time transmission is essential.

Historically, On Line System relied on 3G/4G, but they increasingly suffered:

• mobile network overload due to thousands of spectators
• unreliable coverage in remote forest sections
• unpredictable delays
• occasional loss of split-time packets

A private radio network was needed – one that would operate independently of public infrastructure.

In 2018, On Line System switched to RipEX for split-time transmission.

The setup included:

• three fixed timing points on the course (unchangeable due to event logistics)
• radio links covering up to 15 km
• three hops required for one of the segments
• 25 kHz channel
• robust 4CPFSK modulation
• Flexible protocol for collision-free routing
• reliable TCP/IP transmission of 70-byte packets

To prevent overloading the network, the application queues each packet until a TCP acknowledgement is received from the central timing server.

During the race:

• all three timing locations transmitted simultaneously
• none of the timing stations could “hear” each other
• two repeaters were involved
• potential for collisions was extremely high

Yet RipEX handled:

• simultaneous multi-hop transmissions
• packet collisions
• queueing and retransmissions
• long distances and forested terrain

– all without degrading timing accuracy or throughput.

With RipEX, On Line System achieved:

• secure and stable split-time transmission
• independence from overloaded cellular networks
• real-time delivery to the event centre and TV broadcast crew
• a stress-free race day for timing operators
• a reusable radio setup for future sporting events

As Petr Blažej, owner of On Line System, said:

“We are delighted with the performance levels achieved by RipEX throughout the event. Knowing that the data was being transmitted over a secure and robust link made the whole event a more relaxing experience for us.”

RipEX now plays a key role in ensuring the timing reliability of one of Europe’s most famous long-distance ski races.

How do you maintain reliable communication on a moving overhead transport system inside a heavy-industry manufacturing plant – where powerful motors, steel structures and high EMI levels disrupt conventional communication technologies? For ZPSV in Czechia, the answer was RipEX.

ZPSV s.r.o., a major Czech manufacturer of concrete products for railway and civil engineering, has operated since 1955 and is known for producing the first reinforced concrete sleepers used across the world.

At the company’s plant in Uherský Ostroh, three large production halls are connected via an overhead transport system. Carts move materials between halls, controlled through continuous communication with a central system.

However, the gradual introduction of more powerful industrial motors significantly increased electromagnetic interference.

This caused:

• unreliable Power Line Communication
• delays and stoppages in cart movement
• risk of production inefficiencies and operational downtime

ZPSV needed a communication solution that could:

• operate reliably in a high-EMI environment
• support moving installations
• ensure deterministic, real-time control
• integrate easily with modern TCP/IP systems

RipEX was selected for testing due to its proven robustness in noisy industrial environments.

The communication design used:

• 400 MHz RipEX radio modems
• TCP/IP communication
• Base Driven Protocol for deterministic control
• Forward Error Correction (FEC) for error-free transmission
• Flexible rod antennas, replacing dipoles that physically could not fit through the overhead passage

The final configuration consisted of:

• one fixed RipEX installed near the control room
• three RipEX units mounted directly on moving carts

Despite the COVID-19 quarantine restrictions, RACOM support engineers remotely assisted with configuration, tuning and testing.

After deployment, ZPSV achieved:

• stable real-time communication
• reliable cart movement across all production halls
• resistance to heavy electromagnetic interference
• simplified integration with existing control systems
• confidence to expand the network to the remaining hall

The customer was highly satisfied with the performance and has already ordered additional equipment for network expansion.

RipEX has proven itself as a robust communication backbone for challenging industrial transport applications.
