Advantech has released its latest addition to the ITA series
of wireless rackmount controllers for railway applications: the ITA-5231W. With
multiple wireless connectivity modules for seamless, uninterrupted Wi-Fi, and
LTE network connectivity, the ITA-5231 is well suited for onboard infotainment
systems and reliable train-to-ground data communication.
In order to
provide an uninterrupted wireless connectivity network to passengers while
enabling real-time data connection with train control centers, ITA-5231W
supports multiple WWAN/WLAN modules that allow for simultaneous multi-device
transmission while balancing each individual module’s transmission loading.
The system
features, two mini-PCIe and four M.2 sockets for GPS/3G/LTE/Wi-Fi modules with
18 antenna ports (SMA, QMA, or N-Type). ITA-5231W supports up to 10 SIM slots
(5 dual SIM slots) to ensure an effective network service redundancy solution
for reliable data communication for long distance train travel.
Dual SIM card slots play a critical role in facilitating
roaming between different telecom operators. When a carrier signal is unstable
or disconnects, ITA-5231W can roam in search of a different carrier to ensure fluent
data transmission. When trains enter a station, Wi-Fi transmits relevant data
to the control center in order to reduce transmission costs. During operation,
cellular transmission is performed via TCMS data to allow for remote
monitoring.
Adhering to the strictest possible safety standards, ITA-5231W
meets the EN 50155 and IEC 61373 standard for rolling stock applications. It is
capable of operating under an extreme temperature range of -40°C to 70°C (class
TX), and provides four optional power input (24/48/72/110 VDC) for different
train needs. To enhance the train passenger experience, ITA- 5231W’s seamless
network connectivity delivers a range of multimedia infotainment content that
maximizes passenger experience.
Multiple wireless connectivity modules ensure an
uninterrupted Wi-Fi and/or LTE connection, giving railway passengers the luxury
of movies, music and e-books during train travel. ITA-5231W features an
easy-swap 2.5″ SSD module for operational data storage and onboard
infotainment content storage. Locker design ensures data security by only allowing
specified personnel to access data.
