• Radio card (compatible with IEEE 802.11b/g and IEEE 802.11a/h) permanently installed in device
• Designed without rotating parts (e.g. operation without fans)
• Antennas connected via screw fasteners (R-SMA); These can be replaced within the IWLAN range

The housing and the connectors resist high levels of shock and vibration loading because all the connections are screwed or latched. To achieve optimal illumination for special applications, the supplied antennas can be replaced accordingly. SCALANCE W-740 Client Modules can be operated in the unlicensed ISM bands at 2.4 GHz and 5 GHz.
