Data transfers at the depot (WiFi)

WiFi at the depot: how to automate the data collection ?

To provide even more services and safety to users but also to manage their fleet efficiently, operators need to exchange real-time operating data in motion or at the depot/station (video surveillance, ticketing, passenger counting, PIS…) with buses and trams.

> ACKSYS RANGE OF RUGGED WiFi ROUTERS (EMBEDDED) AND WIFI ACCESS POINTS (AT THE DEPOT) ALLOW A RAPID AND AUTOMATIC TRANSFER OF ALL THESE DATA.

To enable a reliable and simultaneous transfer of all these data coming from the various embedded equipment, ACKSYS’ solution offers advanced security functions (firewall, VPN, radius…) and streams mutualization functions (routing, filtering, VLAN, QoS…).
Only one router per vehicle is needed, simplifying deployment and allowing reduced operating and maintenance costs.

APPLICATION HIGHLIGHTS

SMART DEPLOYMENT

Administration and deployment

WaveManager : deployment & centralized management software
C-KEY : Hardened memory key (confi guration backup)

WiFi coverage

Mesh networks and multi-radios access points : simplify the deployment of a WiFi coverage at the depot or along the track

Embedded WiFi routers

Streams mutualization : a single embedded router, accessible to all the vehicle’s equipment (isolation/ segmentation/ prioritization of flows)
Identical IP addressing scheme in all vehicles without interconnection risks (routing and filtering of flows)

MOBILITY

High speed data transfer in motion (fast roaming <30 ms)

ADAPTED DESIGN FOR TRAMWAY AND GROUND USE

Embedded and outdoor rugged solutions
Extended operating temperature (up to -40°C and + 75°C depending on models)
M12 connectors
EN50155 (IEC61373) / EN50121-3-2 compliant (tram)
EN61373 (shocks/vibrations)

Real time communication in motion (WiFi + 4G)

> CONNECTED VEHICLES: ENSURING QUALITY AND CONTINUITY OF SERVICE

ACKSYS devices offers auto-switch & failover between WiFi and Cellular networks depending on network avaibility, ensuring a seamless data transfer.

In the specific case of trams, when the 4G/LTE network cannot provide a satisfactory level of service or when cellular communication costs become prohibitive (e.g: real-time CCTV, on-board entertainment…), ACKSYS is able to propose a high availability WiFi infrastructure deployed along the track.

ACKSYS guarantees a high speed continuous and seamless connectivity thanks to its secure ground access points and on-board WiFi clients (Connect Before Break technology : packet loss rate < 0.1%).
