  • Page 30: After The Successful Commissioning

    After the Successful Commissioning After the Successful Commissioning After connecting the BAT 11b to the mains power supply and setting up a connection to your Ethernet, it is ready for use. A BAT 11b Wireless Ethernet can be operated either in access point mode (BAT 11b-AP) or in access client mode (BAT 11b-AC).

  • Page 31: Operation Of The Bat 11B As Access Point

    Operation of the BAT 11b as Access Point In this example, the left BAT 11b works as an access point, the right BAT 11b as an access client. All clients in LAN 2 are con- nected to the BAT 11b-AP in LAN 1.
  • Page 32 Operation of the BAT 11b as Access Client Figure: Ad-hoc operation, all clients communicate directly with each other. Figure: Operation in infrastructure mode, all clients communi- cate via an access point. BAT 11b Release 1.0 03/04...
  • Page 33 In this case, only a single computer is directly connected to the BAT 11b-AC via a cross-over Ethernet cable. In the network, the BAT 11b-AC is reached via the MAC address of the con- nected client. In this mode, all protocols can be transferred transparently.
  • Page 34 BAT 11b-AC via a switch. In this case, NAT (Network Address Translation) is applied so that all computers can be reached via the MAC address of the BAT 11b-AC. Therefore, only the IP protocol can be transferred transparently. If protocols other...
  • Page 35 Operation of the BAT 11b as Access Client Mixed Scenario In this scenario, one BAT 11b works as AP, the other BAT 11bs as single AC and multi-AC. In addition, two notebooks are logged on to the AP. Example 1: BAT 11b Release 1.0 03/04...
  • Page 36 Extension of the Range If you wish to connect remote areas and require a wireless cell there, as well, you can also operate a BAT 11b-AP at a BAT 11b- AC. In this case, it has to be ensured that the second wireless cell is operated on another channel, if possible.

    The ad-hoc mode is also referred to as IBSS mode (Independent Basic Service Set) and can be sensibly used in small-scale networks, for instance if two notebooks are to be networked without access point. BAT 11b Release 1.0 03/04...
  • Page 115 In contrast to a static IP address, a dynamic IP address is tempo- rarily assigned via DHCP. Network components, such as Web servers or printers, usually have static IP addresses. Clients, such as notebooks and workstations, normally receive dynamic IP addresses. BAT 11b Release 1.0 03/04...
