> 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 Breack technology : packet loss rate < 0.1%).
APPLICATION HIGHLIGHTS

SMART DEPLOYMENT
– WaveManager : deployment & centralized management software
– Streams mutualization : a single embedded router, accessible to all the vehicle’s equipment
– Identical IP addressing scheme in all vehicles without interconnection risks
– Mesh networks and multi-radios access points : simplify the deployment of a WiFi coverage at the depot or along the track
MOBILITY
– High speed data transfer in motion (fast roaming <30 ms)
– Seamless 4G LTE<> WiFi roaming (mobile IP)

ADAPTED DESIGN FOR BUS, TRAMWAY AND GROUND USE
– Embedded and outdoor rugged solutions
– Extended operating temperature (up to -40°C and + 75°C depending on models)
– RJ45 or M12 connectors
– E-marked devices (bus)
– EN50155 (IEC61373) / EN50121-3-2 compliant (tram)
– EN61373 (shocks/vibrations)
