Abstract: In this paper, we present a detailed design, prototype, and performance of a new, high-fidelity, scalable, Fifth Generation (5G)-New Radio (NR) Network Emulator built on EMANE: 5G-EMANE (5G Extendable Mobile Ad-hoc Network Emulator). The associated software modules are based on the Open-Air-Interface (OAI) open-source models (openairinterface.org). Thanks to EMANE's PHY layer abstraction methodology, the resulting 5G-EMANE offers powerful customization capability that can capture a wide range of scenario diversity with respect to network size, channel models, terrain effects, MIMO antennas, and mobility patterns. The 5G-EMANE also offers a full-stack LTE emulator as part of 5G's non-standalone (NSA) operational scenarios and a full-stack 5G emulator as part of 5G's standalone (SA) mode. A PHY-less version of the 5G-EMANE without PHY abstraction modeling capability, called 5GEM or 5G Layer 2 (L2) Proxy, is offered as open-source software, allowing the 5G research community to evaluate and deploy a full 5G ecosystem using a cost-effective set of commodity PC hardware units for a wide range of scenarios with realistic user-level modeling assumptions but without the complexity of PHY abstraction. Both 5G-EMANE and 5GEM are built on the Small Cell Forum's nFAPI (network functional application platform interface) which enables real-time operation of the entire LTE and 5G stack without the actual over-the-air LTE/5G PHY implementation for multi-user scenarios. 5G-EMANE affords the military community to rapidly conduct research and experimentation while utilizing and integrating LTE/5G with other tactical communications and networking protocols available in EMANE. More importantly, it enables rapid development of new 5G features needed for military usage such as sidelink (SL) without costly and time-consuming over-the-air testbed prototypes.

TL;DR: This work describes the testbed in detail and presents first results of the technical evaluation, as part of the consortiums holistic approach of answering the question if requirements can be met and understanding relevant economic trade-offs.
Abstract: Professional wireless audio equipment such as microphones and in-ear-monitoring systems are popular among live musicians and performers due to their beneficial flexibility and mobility. At the same time, artists have very high technical requirements for these devices e.g., regarding transmission delay, reliability, and battery runtime. In addition, cost, efficient use of scarcely available spectrum, and related scaling factors play a major role in professional audio productions. As of today, the entirety of technical requirements under given constraints can only be met with highly optimized custom RF technology. The new generation of cellular technology 5G is targeted to deliver new ultra-reliable low latency communication (URLLC) use cases similar to forementioned audio scenarios. Within the H2020 project 5G-RECORDS, a consortium of relevant actors from the media and mobile industry are exploring and evaluating 5G technology and related eco systems in the context of professional audio productions. Key element of the consortiums holistic approach of answering the question if requirements can be met and understanding relevant economic trade-offs, is the setup and optimization of a disaggregated 5G testbed. This work describes the testbed in detail and presents first results of the technical evaluation.
