Onboard Wireless Access Point(AP)
Onboard Wireless Access Point (AP) for Railway Passenger Service Systems
The ZTAP series Onboard Wireless Access Point (AP) is a high-performance,
industrial-grade Wi-Fi Access Point specifically designed for rail transit
onboard environments.
As a key wireless access node within the onboard network architecture, it works
in coordination with the Onboard Multi-Network Router and centralized access
controllers to deliver stable, high-capacity wireless connectivity for
passenger service systems and onboard applications.
Optimized RF transmission design ensures consistent signal coverage and
reliable performance under high-mobility conditions, making the ZTAP series
well suited for metro, high-speed rail, and intercity train deployments where
long-term stability and system integration are critical.
Designed for Onboard Railway Applications
The ZTAP series is engineered as the core onboard Wi-Fi access point for
integrated passenger service systems, supporting a wide range of railway
onboard applications, including:
Onboard passenger Wi-Fi access systems
Passenger information and infotainment systems
Train operational data access for onboard terminals
Wireless connectivity for onboard service equipment
Integrated onboard communication networks for multi-carriage trains
By focusing on coverage stability and concurrent user capacity, the AP ensures
continuous wireless access throughout train carriages, even in high-density
passenger scenarios. 
Wireless Performance Optimized for Mobile Rail Environments
This Onboard Wireless Access Point (AP) supports the latest IEEE wireless
standards, providing backward compatibility while enabling higher throughput
and improved efficiency for modern onboard Wi-Fi systems.
IEEE 802.11 a/b/g/n/ac/ax (Wi-Fi 6) compliant
Concurrent dual-band operation (2.4 GHz & 5 GHz)
2×2 MIMO architecture for enhanced signal robustness
Peak wireless data rate up to 1800 Mbps
Supports up to 120 concurrent client devices
The design prioritizes stable signal coverage and reliable throughput rather
than theoretical speed, ensuring consistent user experience across moving rail
vehicles.
Industrial & Railway-Grade Mechanical Design
To meet the demanding requirements of rail transit applications, the ZTAP
series adopts an industrial-grade, rail-compliant design:
Robust aluminum housing for enhanced durability
Passive cooling design to eliminate moving parts
Optimized for long-term onboard installation
Suitable for continuous operation in enclosed carriage environments
This construction approach improves system reliability while reducing
maintenance requirements over the full lifecycle of the onboard Wi-Fi system.
Flexible Deployment: Fat AP and Fit AP Modes
The ZTAP series supports both Fat AP and Fit AP working modes, allowing
flexible adaptation to different onboard network architectures:
Fit AP mode: centrally managed by an onboard Wireless Access Controller (AC)
Fat AP mode: standalone operation or cloud-based AC management
This flexibility makes the AP suitable for both centralized onboard network
designs and distributed deployment scenarios across multi-carriage trains.
Comprehensive Management and Maintenance Capabilities
To support railway operation and maintenance workflows, the ZTAP series
provides comprehensive management and remote maintenance functions:
Web-based configuration and management
Telnet CLI for advanced configuration
Remote software upgrades and batch upgrades
FTP and TFTP support
Remote Syslog for centralized log management
Serial port configuration and debugging
Unified management through onboard AC or cloud AC platforms
These capabilities enable efficient commissioning, centralized monitoring, and
reduced maintenance workload during long-term operation.
