“…In our specific deployment (pictured in Figure 2), we have executed over-the-air applications as high as 71 GHz. To support 6G research, we plan to extend support into the THz band; unfortunately, commercial THz SDRs are not widely available, so we implemented a superheterodyning approach similar to the technique discussed in [31].…”

“…To support 6G research, we plan to extend support into the THz band; unfortunately, commercial THz SDRs are not widely available, so we are actively pursuing a superheterodyning approach similar to the technique discussed later in this paper. Other researchers have successfully built small-scale THz test systems using the same strategy [31]. The WISCANet control software runs on a control computer, which receives a user-defined application and automatically configures the connected edge nodes and radio to execute it.…”

Validating RF applications is traditionally time consuming, even for relatively simple systems. We developed the WISCA Software-Defined Radio Network (WISCANet) to accelerate the implementation and validation of radio applications over-the-air (OTA). WISCANet is a hardwareagnostic control software that automatically configures and controls a software-defined radio (SDR) network. By abstracting the hardware controls away from the user, WISCANet allows a non-expert user to deploy an OTA application by simply defining a baseband processing chain in a high level language. This technology reduces transition time between system design and OTA deployment, accelerates debugging and validation processes, and makes OTA experimentation more accessible to users that are not radio hardware experts. WISCANet emulates real-time RF operations, enabling users to perform real-time experiments without the typical restrictions on processing speed and hardware capabilities. WISCANet also supports multiple RF front-ends (RFFEs) per compute node, allowing sub-6 and mmWave systems to coexist on the same node. This coexistence enables simultaneous baseband processing that simplifies and enhances advanced algorithms and beyond-5G applications. In this study, we highlight the capabilities of WISCANet in several sub-6 and mmWave over-the-air demonstrations. The open source release of this software may be found on the WISCA GitHub page.

“…The majority of the current experimental platforms operating over 100 GHz have been either channel sounders or physical layer testbeds that rely on offline processing [3]. Recently the work in [4], has demonstrated a real-time programmable SDR platform that can support Orthogonal Frequency Division Multiplexing (OFDM) based physical layer with bandwidth on the order of several GHz, and operating at carrier frequencies 120-140 GHz. However, the platform is limited to the link level and no communication protocol stack that includes higher layers runs on the transmitter (TX) or the receiver (RX).…”

This work demonstrates the first-of-a-kind real-time end-to-end 5G connectivity between a user (UE) and the base station (gNB) at terahertz (THz) frequencies. While the gNB's 5G solution is based on OpenAirInterface (OAI), the UE can either be an off-the-shelf commercial 5G mobile terminal or an OAI-based solution. In both nodes, analog THz frontend modules are used to up-convert the intermediate frequency signal into THz frequencies. Implementation details and early experimental results indicating the feasibility of sending 5G waveform at THz frequencies are presented. Such prototypes will facilitate the development of integrated access and backhaul (IAB) solutions using THz links beyond 5G and 6G networks.
