Testbed Features i) User Interface block that allows the user to issue commands and view the final data; ii) Configuration block that alters the functioning of the transceiver circuits and communication protocols based on the state of the network; iii) QoS Monitor block that evaluates if the received data matches the user performance constraints; iv) Receive and Transmit (Rx/Tx) block; v) Data Storage block, which regulates where the large incoming data should be stored and the format for storage; vi) Data Analysis block, which provides an interface to extract and analyze useful information from the received data and present it in a user-friendly fashion.
