3.12 Multiclient Mode
3.12.1 Overview
Multiclient mode is used when there is a need to have several devices (3 and 4 in figure above) behind
the Wireless Bridge that communicates with 1 and/or 2. The restriction is that only one device (3 or 4
in the example) can use Layer-2 communication, while the others need to use the IP layer. The Wireless
Bridge must also be configured on the same IP subnet as the other devices.
For devices to use DHCP over the Wireless Bridge connection while in Multiclient mode, the built-in
DHCP relay can be switched on with AT*ANDHCP, to ensure that all packets are forwarded correctly.
In this case, "DHCP Client and DHCP Relay" is recommended.
3.12.2 Set Up the Use Case
Multiclient mode is configured with AT*ACEW. If no Layer-2 communication is required, the MAC-
address for AT*ACEW can be set to the Ethernet MAC-address of the Wireless Bridge.
