RailTrack is a ruggedized WiFi access point specially designed for railway and certified for trackside and tunnel infrastructures.
It can be connected to the ground network through either Gbps fiber optic or copper connections.

Thanks to an oversized CPU architecture (Quad-Core 64-bit) and three independent 802.11ac high-speed radio cards (3 streams) delivering more than 900 Mbps (UDP) each, RailTrack access point allows the construction of high performance architectures such as "wireless backbone" to overcome Ethernet cables along tracksides and tunnels : 2 radios can be used to build the wireless infrastructure on the trackside while the 3rd radio is used as local AP to provide communication between the trackside and the train.

Featuring an IP66 housing and rugged M12 connectors, RailTrack is ideal for wall mounting in a tunnel or mast mounting outdoor. Its all-in-one compact footprint integrates 3 radios, a 4-port Ethernet switch (2 x 10/100/1000 on M12 connectors & 2 x Gigabit optic fiber on SFP slots) with optional Ethernet bypass (daisy chain topologies) and an AC power supply. A removable key (C-KEY) allows the device configuration backup. It can thus be instantaneously restored on site in less than 2 minutes in case of maintenance or replacement of a RailTrack.

RailTrack (trackside AP unit) combined to RailBox (on-board WiFi unit) is the comprehensive connected architecture for "train-to-trackside communication in motion" by ACKSYS. This ACKSYS solution allows reliable and very high-speed broadband train-to-trackside communications, particularly suited to Internet on board applications, real-time video surveillance and CBTC.
