Real time communication in motion

> 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%).

 

 

 

 

 

 

 

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)
– Seamless 4G LTE<> WiFi roaming 

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)
