    SB4

    As shown in Figure 1, sandbox 4 consists of 8 nodes and a WiMAX subsystem that consists of a basestation and a controller. To prevent interference, each node is housed in ​Ramsey Electronics RF enclosure that provides 80 dB of isolation. Nodal wireless devices (Atheros 5000X mini-PCI card and Intel 6250 mini-PCIe 802.11/802.16) are connected to a power combiner and fed through the enclosure access port to the outside SMA connector which is wired to one of the input/output ports of the ​RF Transceiver Test System from ​JFW Industries. This configuration enables fairly tight control of RF attenuation between the nodes. The topology is controlled through the ​OMF based Instrumentation AM.
