    99===== RF Node Hardware =====
    1010
    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.

    1313 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.

    33  '''Matrix 1:''' (2 - 6 GHz)
     33 The RF connections of the enclosures housing the nodes as well as the antenna connections of the LTE and WiMAX base stations are all connected to the RF transceiver test system which is composed of an array of RF switches and two attenuator matrices. This system is capable of handling two completely independent topologies: one with up to 9 devices and the other with up to 5 devices, permitting a wide range of experiments to be conducted, including spectrum sharing and multi-homing. Users can configure which devices connect to which matrix and dynamically control the attenuation of each connection pair using the [wiki:/Software/eAM/mInstr Instrumentation AM] service.
