     3The Orbit Noise Generator acts as a radio node for generating a controllable noise source, an important parameter in defining signal-to-noise ratios during ORBIT experimental operations.  Upwards of 100 ONGs will be deployed among ORBIT’s 400 primary radio nodes. ONG shown in Figure 1 consist of two printed circuit boards:

     5 1. [wiki:Internal/NoiseGenerator/Hardware/BiBo Baseband Board (BiBo)] a USB enabled baseband processing board centered around Xilinx Spartan 3 FPGA and Analog Devices A/D and
     6 2. [wiki:Internal/NoiseGenerator/Hardware/WiBo Wireless Board (WiBo)] which is a custom built WLAN radio transceiver board capable of half duplex (one-at-a-time receive-only or transmit-only) operation in one of three frequency bands, namely 4900-5300 MHz, 5400-5875 MHz or 2400-2500 MHz that correspond to the IEEE 802.11 a/b/g world-wide standards, respectively.
