The SCALANCE W788-1PRO access point is highly suitable for 

designing Industrial Wireless LAN (IWLAN) radio networks with 

reliable communication. It has an Industrial Ethernet interface for 

the connection to the wire-bound network.
Special features of the SCALANCE W788-1PRO access point
• Versatile power supply facilities (operation on 100 V to 240 V 

AC network with PS791-1PRO power supply)

• Antenna diversity for reliable reception in complex radio envi-

ronments with two ANT795-4MR omnidirectional antennas 

screwed onto the housing, can be replaced by other types 

from the SCALANCE W700 range

• Transmission rate up to 54 Mbit/s at 2.4 GHz and 5 GHz with 

radio approval in more than 30 countries

• Conforms to the IEEE 802.11b/g and IEEE 802.11a standards
• WPA and 128-bit encryption (AES) for high security against il-

legal access

• Rugged metal enclosure resistant to shock and vibration, and 

with IP65 dust protection

• Suitable for ambient temperatures from -20 to +60°C (resistant 

to condensation)

For further information and detailed technical specifications, re-

fer to Catalog IK PI, the A&D Mall or Catalog CA 01 under "Com-

munication/networks, SIMATIC NET communication systems, In-

dustrial mobile communication".

The data and power connections for the SCALANCE 

W746-1PRO Ethernet client module and the SCALANCE 

W788-1PRO access point can be made using a hybrid cable or 

separate cables (preferably over short distances):
• With separate cables, a 4-core TP (2 x 2) IE FC Standard Ca-

ble (type A) is used as the data cable. This Industrial Ethernet 

cable is connected on site to the supplied IP67 hybrid plug 

connector. A Power M12 Cable Connector PRO is additionally 

required for the power supply. IE FC Standard Cable and 

Power M12 Cable Connector PRO must be ordered in addi-

tion.

Example of data and power supply connections using separate cables

• If the data and power supply are connected using one cable, 

an FC Modular Outlet with power insert and the hybrid cable 

must be ordered in addition. The hybrid connector included in 

the scope of supply and the FC Modular Outlet with power in-

sert can be assembled and connected on site.

Example of data and power supply connections using a hybrid cable

• If 100 ... 240 V AC is available on site, the PS791-1PRO power 

supply can be used (to be ordered in addition). It is supplied 

including AC connector and cable to the Ethernet client mod-

ule/access point, but without AC cable.
