Passenger connectivity
Passengers expect seamless
mobile coverage throughout their journey. This is hard in rail environments.
Tunnels, underground stations, and cuttings degrade mobile signals. Passenger connectivity is
also inhibited inside the carrier due to signal degradation due to the physical
make up of train carriages and the quality of each windows. Even when outside coverage is strong, coverage inside carriages can be poor.
We design and operate radio
systems that bring all three major mobile carriers (Telstra, Optus,
TPG/Vodafone) into corridors and stations. One network covers all carriers
simultaneously. Passengers stay connected on their own network with no dropouts
or carrier switching.
This approach cuts cost and
construction time for rail operators while significantly improving passenger
experience. Reliable connectivity underpins real-time travel information,
contactless payments, directions, and digital services.
Benefits can include:
- Improved passenger satisfaction and experience
- Single network covering all major carriers, so passengers stay connected on their own network
- 4G and 5G coverage in tunnels, underground stations, and below-ground areas where standard networks can't reach

Smart signalling
ETCS Level 2 signalling is the
primary driver of investment in modern rail systems. This European standard is
being adopted across Australia, with NSW targeting go-live around June 2027.
Legacy signalling systems are expensive to maintain and limit train service frequency.
Modern ETCS Level 2 systems leverage
high-speed, low-latency wireless networks to enable more frequent trains,
real-time train positioning, and eventually autonomous operation. This is fundamentally different from other approaches (like
Wi-Fi-based systems) that require significantly more hardware to facilitate end
to end communications with access points every 50–75 metres in tunnels, and
demand heavy maintenance programs.
We've designed our 5G network
to meet the strict demands of safety-critical signalling. It prioritises train
control traffic, isolates it from other data, and reserves capacity for future
automation. We work with leading partners and don't lock customers into a
single vendor. Our network is the foundation that lets partners do their best
work.
Benefits can include:
- Higher throughput: ETCS Level 2 and moving-block signalling let trains run more frequently
- Lower infrastructure costs: 5G network replaces expensive, hard-to-maintain trackside equipment
- Path to automation: The network foundation for driver-advisory systems and eventually fully autonomous trains
- Vendor-agnostic connectivity that integrates with leading signalling solutions

Predictive maintenance
Unplanned maintenance is a
major cost and reliability risk for rail operators. Predictive maintenance uses
continuous sensor data to shift from reactive repairs to proactive
intervention.
We fit sensors to rolling
stock, track, and station assets. They constantly transmit data on vibration,
temperature, wear, and performance. Analytics identify problems before they
become failures. Maintenance teams prioritise work based on actual asset condition,
not fixed schedules.
Our network provides the
reliable, high-bandwidth connectivity needed to transmit continuous sensor data
from moving trains and distributed assets. It integrates with leading fleet
management and asset monitoring platforms. This approach, backed by next-generation
mission-critical communications standards, helps rail operators optimise
maintenance spend and improve reliability.
Benefits can include:
- Lower total cost by cutting unnecessary preventive maintenance and optimising resource use
- Fewer service disruptions with predictive analytics identifying faults before failure
- Optimised schedules. Maintenance based on actual asset data, not fixed intervals

Rail
Connecting
rail networks every day, keeping passengers and operations on track.
We design and operate
mission-critical rail networks that keep operations safe and efficient. Our
networks support three separate but connected layers: train control and
signalling, passenger mobile connectivity, and emergency services
communications.
Rail operators have
traditionally had to work with multiple providers to cover these three areas.
We deliver all three through one integrated solution, which reduces complexity
and cost.
Rail infrastructure is ageing.
Operators need modern systems and new standards to replace outdated equipment.
The main driver of investment is ETCS Level 2 signalling, a European standard
Australia is now adopting. It enables trains to run more frequently and gives
more capacity. Supporting this shift requires next-generation communications
for voice, video, and data, especially as metro systems move toward driverless
operations where live video to control centres is critical for safety.
We have proven expertise in
mission-critical networks and 24/7 in-country support. We manage Australia's
largest public safety network. This experience positions us to deliver the
reliability and uptime that modern rail systems demand.

Metro
Keeping metro networks
connected, safe and commercially ready, above and below ground.
Metro systems need three
separate connectivity layers: mission-critical networks for train operation and
control; public mobile coverage so passengers stay connected on their own
carrier (Telstra, Optus, TPG/Vodafone); and dedicated networks for emergency
services.
We deliver all three through
one integrated network. This gives metro operators a single partner for all
connectivity instead of managing multiple vendors. One integrated approach cuts
complexity, improves safety coordination, and gives operators the reliability
that modern metro systems demand.
