Overview
1-1. Features
WE70-AP/CL is a FA wireless LAN unit set conformance to IEEE802.11a/b/g.This section describes
features of the FA wireless LAN unit set WE70-AP/CL.
Connecting this wireless unit set to a PLC Ethernet unit allows wireless monitoring of facility
information through network as with wired connection.Ethernet unit functions can be used via radio
communications as they are.
(e.g. FINS communication service/socket/FTP server/e-mail transmission)

Main Features
●
FA wireless LAN units conformance to IEEE802.11a/b/g
This wireless unit set supports world-standard IEEE802.11a/b/g: both 5GHz band in IEEE 802.11a and
2.4GHz band in IEEE 802.11b/g.(Switched by setup and cannot be used simultaneously.)
FA sites having used various types of wireless devices (such as wireless LAN, RF-ID, WD30/WT30),
2.4GHz band has been congested.If you have difficulty in installing a new wireless system due to radio
interference, 5GHz band is recommended.5GHz band allow installation of additional wireless systems
without influences on existing wireless systems.(Up to 24 systems)
■ Channel assignment based on frequency band
