The SCALANCE W774 M12 EEC (Extended Environmental Conditions) are designed for use in railway applications. The devices satisfy EN 50155, the approval for railway applications, and can thus be used for rail traffic. Combined with the antennas approved for railway applications, which are connected via R-SMA antenna connectors (female), these products can set up a reliable IWLAN wireless infrastructure.

The devices can be installed at the location that is most favorable for the wireless link. The enclosure and the connectors are resistant to high levels of shock and vibration because all the connectors are screwed or locked. The SCALANCE W774 M12 EEC is well suited to environments in which a compact design plays a large role. Through its coated printed-circuit boards (Conformal Coating), the module is resistant to condensation caused by use in environments with large temperature variations.

SCALANCE W774-1 M12 EEC access points can also be operated as client modules.

Provided that a delay (several 100 ms) caused by roaming in accordance with IEEE 802.11 is tolerated by all communication stations when switching the radio cells, the communication continues uninterrupted.

For real-time requirements, the SCALANCE W774-1 M12 EEC can be equipped with KEY-PLUG functionality for activating iFeatures.
