Topology Control in SB4
As shown in Figure 1, sandbox 4 consists of 8 nodes and a WiMAX basestation. Both wireless devices (Atheros 5000X mini-PCI card and Intel 6250 mini-PCIe 802.11/802.16) are connected through fixed attenuators to the input/output of the ports of the matrix.
Topology is controlled with the RF Transceiver Test System from JFW Industries which is a 9 port programmable attenuator based test system. The topology is controlled through the OMF based Instrumentation AM.
Basestation is controlled through OMF based WiMAX RF Aggregate Manager Service that is running on machine cons-wm-01.
Example of topology control (execute on console.sb4):
To set attenuation between node1-8 and the BS to 20 dB

Example of wimax control (execute on console.sb4):
To turn ARQ on (ARQ Control part of wimaxrf AM)
