Open Radio Access Network (O-RAN) is a major carrier-led effort to disaggregate the next generation of virtualized RANs for multi-vendor deployments. It is aimed at disrupting the vRAN ecosystem by breaking vendors lock-in and opening up a market that has been traditionally dominated by a small set of players. When successful, Open RAN will unleash an unprecedented level of innovation in the 6G space by lowering the market entrance barrier to new competitors. Harnessing the strengths of opening the radio access arena, however, entails a number of daunting challenges that need to be addressed. Managing the increased complexity of Open RAN 6G networks with traditional human-in-the-loop approaches will not be possible anymore. Instead, zero-touch technologies that fully automate the network operation will become the standard, and the success of 6G will vastly depend on the quality of the Artificial Intelligence (AI) solutions that will run at schedulers, controllers, and orchestrators across network domains, and de-facto manage the infrastructure. While Open RAN interfaces will facilitate AI network management operations, new challenges will be introduced in terms of network data processing and timely management actions decisions. This project will focus on exploring the limits of AI-driven network automation in future 6G systems. For this reason, Open6G will build on the Open RAN efforts ongoing today to tackle the aforementioned challenge and design and develop an Open 6G Testing Platform for novel networking and sensing applications.

Nanotechnology is paving the way toward nanoscale devices that are envisioned to enable several groundbreaking healthcare applications, such as molecular-level cancer detection, targeted drug delivery, and neurosurgeries. The nanodevices are expected to flow through the human body, perform actions upon commands or at certain locations, and communicate the results to the outside world. There is, therefore, a need to enable two-way communication between the nanodevices and the outside world, as well as their localization inside the body. These functionalities should be supported while simultaneously maintaining tiny form factors and a low energy consumption profile of a potentially vast number of nanodevices. In the ScaLeITN project, we will utilize wireless signals in the terahertz (THz) frequencies for enabling both localization and communication capabilities for in-body nanodevices. Localization will be enabled through THz backscattering, which is an unexplored paradigm that promises low energy and high precision localization at the nanoscale. The constrained communication range characteristic for in-body THz propagation will be mitigated through multi-hop communication. In such communication, only a selected subset of nanodevices in the multi-hop route will be awoken by utilizing wake-up radio-like signals. Selection of these nanodevices will be based on their location estimates, as well as on their energy lifecycle characterizations if available through backscattering. This is again a novel paradigm that promises enabling low power, reliable, and scalable THz nanocommunication. The main outcome of the project is to develop a pioneering prototype of a THz nanonetwork with both localization and two-way communication capabilities. Market valorization of the prototype is envisioned during and beyond the scope of the project through the Collider and i.start, two academic innovation programmes for supporting scientists in developing disruptive technology-based products.

The latest generation of WiFi technology, known as mmWave WiFi, utilizes comparatively higher frequencies than traditional WiFi. To combat high signal attenuation at mmWave frequencies, mmWave WiFi utilizes directional transmission and reception of signals. By utilizing directional communication at high frequencies, and in contrast to omni-directional and low-frequency traditional WiFi technologies, mmWave WiFi can deliver tens of gigabits per second bitrates required by various ground-breaking applications (e.g., virtual reality and aerial wireless networks). To establish strong communication links, in mmWave WiFi the directions of transmit and receive beams must be properly aligned, which is a process known as beam-steering. The current beam-steering mechanisms do not perform well under in dynamic conditions, i.e., when the communicating devices are mobile or if there are humans obstructing the communication. Therefore, there is a need for developing new beam-steering mechanisms that will be able to mitigate these negative effects. Consequently, experimental evaluation of these newly developed mechanisms will be required in order to benchmark their performance against the existing ones. To guarantee fair comparative benchmarking, there is a need for highly repeatable experimentation, i.e., different instances of an experiment must be performed in a way that preserves all experimental conditions (apart from exchanging the beam-steering mechanisms), pertaining primarily to the repeatable mobility patterns of the communicating devices, as well as the mobility patterns of humans causing obstacles. Such conditions cannot be achieved if humans are involved in the experimentation, either as carriers of devices or as obstacle generating factor. To alleviate these issues, we will develop a testbed infrastructure for fully repeatable mmWave WiFi experimentation with device mobility and moving obstacles. The repeatability will be guaranteed by utilizing drones as the carriers of mmWave WiFi devices and a combination of a robotic mobility platform and mannequin resembling a moving human-like obstacle. Once developed, this testbed infrastructure will increase the visibility of our university to a large heterogeneous audience and allow as to kick-start our research activities in the highly-promising mmWave WiFi domain. In addition, the testbed will be convenient for a broad range of experimentation with mobile wireless infrastructures going beyond the scope of the initially envisioned beam-steering in mmWave WiFi experimentation.

The IoT domain is characterized by many applications that require low-bandwidth communications over a long range, at a low cost and at low power. This has given rise to novel radio technologies that try to fill in this existing market gap of low-power wide area IoT networks, often referred to as Low Power Wide Area Networks (LPWANs). Due to the use of sub-GHz radio frequencies (typically 433 or 868 MHz), a single LPWAN base station has a large coverage area, with typical transmission ranges in the order of 1 up to 50 kilometers. As a result, a single base station can support high numbers of connected devices (> 1000 per base station). Notorious initiatives in this domain are LoRa and Sigfox. Although these standards have similar goals, they are very different in terms of technology (e.g., wideband vs ultra narrow band), operation mode (multiple versus single operator) and whether or not a company is allowed to install their own gateways. Very recently, the IEEE 802.11 family has been extended with a LPWAN solution, IEEE 802.11ah. Like existing Wi-Fi, 802.11ah provides IP-based connectivity, allowing devices to communicate with a broad range of hardware platforms. As such, this technology is a prime candidate for inclusion in future residential and industrial access points. To further complicate the technology choice for companies, other technologies such as DASH7, Weightless and IEEE 802.15.4g utilize the same radio frequencies, thereby competing (and possibly interfering) with other LPWAN technologies. The aim of the IDEAL-IoT project was to develop management and optimization solutions for real-time control, reconfiguration and optimization of LPWAN networks to improve co-existence of different technologies, improve scalability, support handovers and meshing and add differentiated QoS support. In addition, the project yielded a set of management and application services for indoor/outdoor localization, diagnostics & monitoring, scalable network & QoS management, multi-provider optimizations, network virtualization & software defined networking, and deployment & network planning.

In several areas of industry, 100%-operational mission-critical communication platforms are a must. In other industrial scenarios, asset management requires vehicles and goods to be tracked over long distances and periods of time, with a variable demand towards accuracy and data throughput. At the start of the MuSCLe-IoT project, no single wireless technology in itself was capable of assuring this type of specifications at acceptable cost. License-exempt low-power wide-area network (LPWAN) technologies (SigFox, LoRa, DASH7, 802.15.4g) are reliable and power efficient. Yet, each of them is designed for specific use cases, which limits their wider applicability. To cover the demands of a lot of today’s applications, multiple (redundant) systems - wireless and wired - are being deployed in parallel. Often resulting in the desired performance, but adding a lot of cost and complexity in the installation and interoperability. Within MuSCLe-IoT, a solution has been developed that makes optimal use of multiple LPWAN standards for mission-critical communication and long-range multi-year asset management. An example of such operation is to switch to LoRa at times when DASH7 coverage is lower or communicate over SigFox when less data throughput is needed. The MuSCLe-IoT prototype consists of a small, low-cost, battery-powered single-antenna device in combination with the required software algorithms for cloud- and edge computing to control the network. The MuSCLe-IoT technology can be seamlessly implemented with existing communication devices (e.g., DECT phones, pagers) at much lower cost of ownership compared to wired or redundant system installations. It can revolutionize the uptake of IoT solutions in sectors as marine (harbors), construction, retail, museums, and many more.

The EVARILOS project addressed one of the major problems of indoor localization research: The pitfall to reproduce research results in real life scenarios suffering from uncontrolled RF interference and the weakness of numerous published solutions being evaluated under individual, not comparable and not repeatable conditions. Accurate and robust indoor localization is a key enabler for context-aware Future Internet applications, whereby robust means that the localization solutions should perform well in diverse physical indoor environments under realistic RF interference conditions.
