Description

Figure 4-37
The access points W788-x RJ45/W788-x M12 and the client modules W748-1 RJ45/W748-1
M12 support the standard IEEE 802.11a/b/g/n. These devices are intended to set up
Industrial Wireless LAN (IWLAN) wireless networks for 2.4 GHz or 5 GHz.
The devices SCALANCE W788/W748 use three data streams and therefore achieve data
rates up to 450 Mbps. The high data rate is achieved among other things by channel
bonding and by 3 x 3 MIMO technology (Multiple Input, Multiple Output), see section IEEE
802.11n/ac (Page 209) The devices each use three data streams for the simultaneous send
and receiving of wireless signals.
The access points SCALANCE W788-x RJ-45 and the client module SCALANCE W748-1
RJ-45 are particularly suitable for applications in which the access point is to be installed in
the cabinet. The robust aluminum housing of the SCALANCE W788 RJ-45 devices in degree
of protection IP30 provides protection from mechanisms and electromagnetic loads and is a
cost-effective alternative for use in indoors.
The access points SCALANCE W788-x M12 and the client module SCALANCE W748-1
M12 can be installed at locations with suitable wireless properties indoors also outside the
cainet. The housing with degree of protection IP65 and the connectors withstand high loads
caused by shock and vibration since all connections are screwed or lock in place.
The access point SCALANCE W788-2 M12 EEC also has an extended temperature range
and conformal coating. The maximum ambient temperature for operation of this device is 70
°C.
