    4 As shown in Figure 1, sandbox 4 consists of 9 nodes and a WiMAX subsystem that consists of a basestation and a controller. To prevent interference, each node is housed in [http://www.ramseytest.com/ Ramsey Electronics RF enclosure] that provides 80 dB of isolation. There are  8 nodal wireless devices (with Atheros 5000X mini-PCI card and Intel 6250 mini-PCIe 802.11/802.16); these 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 [http://www.jfwindustries.com/documents/50PMA-012_specsheet.pdf  RF Transceiver Test System] from [http://www.jfwindustries.com JFW Industries]. This configuration enables fairly tight control of RF attenuation matrix between the nodes. The topology is controlled through the [http://omf.mytestbed.net OMF] based [wiki:Software/eAM/mInst Instrumentation AM]. NOTE: Data Ethernet port is not connected on the nodes in SB4.
