    4 Sandbox 4 consists of 10 nodes along with two LTE and two WiMAX base stations with corresponding BS controllers. The RF connections of these nodes and base stations are wired using low-loss coax cables to a set of RF switches and two programmable RF transceiver test systems (attenuator matrices) for controlled and repeatable experimentation using various topologies.

    66Nine of the nodes are equipped with wireless hardware, while the remaining one (node2-1) is intended as an ethernet only device for CUDA processing. To prevent interference, each of the 9 RF nodes is housed in its own [http://www.ramseytest.com/ Ramsey Electronics RF enclosure] that provides 80 dB of isolation.

    10 Of these, 4 are also equipped with [wiki:Hardware/fDevices/cSDR/gUSRP#USRPB205  USRP B205mini-i] SDR devices. Additionally, there are 3 nodes with All of the antenna ports of in each node 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. Four of the RF test system ports are shared between nodes and basestations (node1-1 and node1-2 are sharing their port with LTE baestations while node1-8 and node1-9 are sharing their ports with WiMAX basestations). The topology (including pairwise attenuation between ports and selection switches for node/basestation) is controlled through the [http://omf.mytestbed.net OMF] based [wiki:/Software/eAM/mInstr Instrumentation AM].
     11 Each of the RF nodes is equipped with a pair of WiFi devices: one Atheros 5000X mini-PCI card and one Intel 6250 mini-PCIe 802.11/802.16. The antenna connections of these wireless cards are connected through individual 15dB attenuators to a power combiner which connects through a single enclosure access port to the RF test system. This connection is referred to as "!WiFi/WiMAX" in subsequent diagrams.

     13 Four of the RF nodes are also equipped with [wiki:Hardware/fDevices/cSDR/gUSRP#USRPB205 USRP B205mini-i] SDR devices. The TX/RX and RX2 ports are connected through individual 15dB attenuators to a 2-way power combiner which connects through the second enclosure access port to the RF test system. This connection is referred to as "USRP" or "SDR" in subsequent diagrams.

     15 Three of the RF nodes are also equipped with [wiki:Hardware/fDevices/dWide#LTEHardware USB LTE client adapters] for experimentation using commercial clients. The antenna connections of the adapters are connected through individual 15dB attenuators to a 2-way power combiner which connects through the second enclosure access port to the RF test system. This connection is referred to as "LTE Client" in subsequent diagrams.
