    Commissioning Selecting an Appropriate Location Select an appropriate location where you want to mount the device. If possible, the antenna should not be covered by metal parts and should be freely visible. ComPoints should be mounted in the center of the planned wireless cell. Usually, the quality of the radio transmission increases the higher the antenna is mounted.

  • Page 17 After Successful Commissioning Figure: Ad-hoc operation, all clients communicate directly with each other. Figure: Operation in the infrastructure mode, all clients commu- nicate via an access point.
  • Page 18 After Successful Commissioning Operation as Single-Access Client In this case, only one computer is directly connected to the CPB- AC. In the network, the CPB-AC is reached via the MAC address of the connected client. In this mode, all protocols can be trans- ferred transparently.
  • Page 19 After Successful Commissioning Operation of the ComPoint as Multi-Access Client This operation is possible in the infrastructure or ad-hoc (peer-to- peer) mode. Several computers are connected to the CPB-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 CPB-AC.
  • Page 20 After Successful Commissioning Mixed Scenario In this scenario, one CPB works as AP, the other CPBs as single ACs and multi-ACs. In addition, two notebooks are logged on to the AP. Example: CPB-AP Switch CPB-AC Switch CPB-AC 1-12...
