1. ATS1211 ATS 1212 Description Channel list Use as few channels as possible because this will affect the handover time Use this AT command for the Roaming RSSI diff threshold When you set this value low it will result in an earlier handover but might also make the BAT C s switch too often Having it too high might make the handover come too late Recommended here is that you use the default values These values directly influence the behavior of the Bridge Discovery Protocol If you alter these values modify them very carefully otherwise the BDP might stop working See AT command specification for more info This value represents the RSSI depth Use a low value to detect a low RSSI faster Trigger Scan RSSI The device uses no reference to this value when operating in the seamless roaming mode since the slave is continually scanning However if the slave stops working for some reason the master will start scanning in the background BDP group ld Set this value to the same for every device involved in a seamless roaming scenario Display BDP role on LEDs LED update interval You are required to set the BDP group Id AT AMBGID the other settings are optional However it is highly recommended to fine tune the other parameters to suit your specific application When using the BAT C s for redundancy the parameters with the exception of AT AMBGID have no significant impact 3 13 2 Limitations To use s2.

3. WPA2 IEEE 802 1 1i Overview Ethernet Ethernet WLAN Access Point The Multi Client mode is used when there is a need to have several devices 3 and 4 in figure above behind the BAT C that communicate with 1 and or 2 The restriction is that one device at a time can use Layer 2 communication while the others need to use the IP layer When configuring the BAT C in the Client mode and there is no link on the Ethernet port it will use a temporary Multi Client mode instead Once there is an Ethernet link the BAT C will revert to the Client mode lf devices want to use DHCP over the BAT C connection while in the Multi Client mode The built in DHCP relay can be switched on using AT ANDHCP and the Web Interface Verify that the device forwards packets correctly 3 12 1 How to setup this example The Multi Client mode is configured using AT ACEW and the Web Interface if no Layer 2 communication is required The MAC address for AT ACEW can be set to the Ethernet MAC address BAT C 35 Release 01 08 2012 3 13 Seamless roaming and redundancy Operation Client and Multi Client mode Encryption WEP WPA WPA2 IEEE 802 1 1i Overview Network 1 Network 2 BAT C 1 2g Device 2 i et BAT C 2 Feecy Creve tan barr EARS RALES BREESE REALS Device 1 See s Ceres eee ey Geeee SUES Cee eS Piece Wi eEs When roaming between access points with one BAT C An interruption in data flow will occur
4. because the BAT C first disconnects from one access point and then connects to another A way to minimize this loss of data is to use two BAT C s connected to the same network and switch on seamless roaming The example above represents a typical application In this scenario verify that network 1 maintains a connection to network 2 Typically the wireless devices in network 1 are wireless access points AP and the devices in network 2 are wireless clients The roaming functionality is located on the client side hence network 1 can use standard wireless hardware without any special firmware For this reason further illustrations exclude the AP network side The wireless clients act like bridges forwarding packets from network 1 to network 2 and vice versa In order to avoid network loops one client at a time forwards packets A protocol controls this mechanism the Bridge Discovery Protocol BDP which uses the local link in order to prepare and execute roaming and redundancy BDP defines three device modes roles Master Slave and Available When the wireless clients reboot they will enter the Available device mode The goal of the protocol is then to elect one Master and one Slave on the local link The Master is the device that is in charge of roaming etc by controlling the Slave over the local link Note 1 The Client and Multi Client mode support seamless roaming and redundancy Note 2 To achieve the best results connect both o
