Figure A1-3 Minimum system configuration example (The field wireless backbone using wireless LAN
network)
In this configuration example, the wireless LAN access point (other manufactures) is installed on
the field wireless backbone, and each YFGW510 is connected to the field wireless backbone via
the wireless LAN. If YFGW510 are connected via the wireless LAN, a single YFGW510 can be
connected to a single field wireless subnet. Using YFGW510 wireless LAN redundancy model
and two wireless LAN access points, the wireless LAN communication can be made redundant.
Similar to the other field wireless backbone network, up to 20 field wireless subnets can be con-
nected to the YFGW410. Up to 100 field wireless devices can be connected in each field wireless
subnet, and up to 500 field wireless devices can be connected to the YFGW410.
For the recommended wireless LAN access points, see Section G2.7 Recommended Device
List.
