In the presentation I outline why FinFET design is essential in delivering MIMO systems, showing that while drawbacks do exist they can be overcome, explaining the key design challenges and providing rules to help analog engineers.

Background
5G terrestrial and satellite communications have already begun to use bands in the FR2 range (24~52GHz). The range of wireless communications in these bands is limited by the short signal wavelength and transceivers therefore rely on the integration of MIMO systems to meet the link budget and mitigate interference. For the ASIC designer, this means more channels, more radios, more digital signal processing.

Power consumption
FinFET is the ideal technology for large MIMO systems; by enabling ‘digital radio’ solutions, based on RF-ADCs/DACs, it gives the flexibility to design ASICs that support multiple standards. There is, however, a drawback in implanting this architecture: power consumption. Energy-per-conversion increases exponentially when operating above 1 GHz; for example, moving the sampling frequency from 1 to 5GHz, increases the converter power by 20x.

Significant power can be saved by designing an RF analog front end (AFE), converting the multi-GHz RF signal to a lower intermediate-frequency (IF) below 500MHz, before performing the transition to the digital domain and relaxing the data-converters sampling frequency.

Further benefits
Using FinFET for analog design introduces multiple benefits: devices are compact, the high Gm and Rout are ideal to design analog amplifiers, RF designers can leverage the excellent high-frequency performance, with peak fT of 600GHz.

Again, there is a drawback to this approach too: the number of masks required by the technology is 2/3 times higher than in planar geometries. The amount of design rules increases accordingly, making the technology better suited for ‘machine driven’ digital implementations. Attempts to use custom analog layout flows are bound to fail, especially when using the smaller (7nm) nodes to achieve highest system integration and lowest power consumption.

Rules to design MIMO in FinFET technology
In FinFET, making a regular analog layout is paramount for success. Any variation from this approach may give some short term advantages in the initial schematic simulations, that disappear when parasitic resistors (due to metals and VIAs) are introduced. Simulations are slow and engineers need to resort to approximations to control simulation time.

The implementation challenges are significant, but so too are the benefits. The following rules can help engineers handling the intricacies of FinFET analog design:
1.Do not mix devices having different dimensions
2.Use repeatable patterns
3.Estimate interconnect parasitics from the start
4.Use digital calibration to correct analog errors
5.Current density limits the transmitter output power
6.Corner frequency of flicker noise is high
7.Simulations are slow

Advancements in Micro-acoustic Resonators

This session aims to provide a comprehensive overview of advancements in micro-acoustic resonators, primarily used in Radio Frequency (RF) filters and their role in the RF Front-End. Following an introduction to the fundamentals of RF filters, we will discuss different types of micro-acoustic filters and the materials and processes used for developing such devices. We will provide insights into filter design approaches and R&D hotspots for surface acoustic wave (SAW) and bulk acoustic wave (BAW) filters.
These insights will include a discussion of various design considerations including an exploration of distinct types of acoustic wave modes excited by different piezoelectric materials and their associated filter design trade-offs. The presentation will also explain how such design considerations accommodate the push towards higher frequencies and more complicated band combinations due to further developments in 5G and 6G communications. In the final section, we will highlight the packaging challenges surrounding micro-acoustic devices.

The evolution of 3GPP (the 3rd Generation Partnership Project) standards has made tremendous progress with 5G. Initial 5G has targeted three main use cases enhanced Mobile Broadband (eMBB), ultra-reliable and low-latency (URLLC), and massive IoT, new verticals were added in later releases. To further enhance 5G capabilities, 5G Advanced builds on the 5G baseline defined by 3GPP in Releases 15, 16, and 17.

3GPP Release 18 is the starting point of 5G Advanced. 5G Advanced will enhance network performance and add support for new applications and use cases such as the metaverse, Redcap devices, and the joint communication and sensing (JCAS) within the same system or network. The journey to enhance the network performance with AI/ML, applying AI/ML for indoor positioning and AI/ML area to support network energy saving has just started and to be enhanced in Release 19 and beyond.

Several of the 5G advanced technology components can be seen as starting point to some of the 6G building blocks. For example, AI/ML will play an important role in the fully data-driven architecture of 6G.

This presentation provides an overview of 3GPP journey towards 5G advance and 6G technologies.

Cellular communications connects people around the world using radio-frequency spectrum. The harmonization of global spectrum is precisely defined and managed by the International Telecommunication Union – Radiocommunication Sector (ITU-R). Without the support of governments, regulatory authorities, and industry experts, we would not have been able to enjoy the benefits of wireless internet in 3G, internet of applications in 4G, and ubiquitous connectivity in 5G. These generational advancements are driven not only by the insatiable and ever-increasing demand for capacity but also by the rising number of smart devices and subscriptions, as well as an increase in the average data volume per subscription. However, upon closer examination, we find an intricate set of requirements and design complexities that intertwine. These include market requirements and applications, technical specifications, and radio technology developments, all of which must align with wireless standardization activities.

The ITU-R has developed a framework for IMT-2030 (also known as 6G), which encompasses emerging services, applications, and technical aspects. One of the pillars of this framework is the integrated multi-dimensional sensing technology, which aims to enhance high-precision positioning through object and presence detection, localization, imaging, and mapping. Furthermore, communication operations at higher emerging spectrum (also known as FR3 band) and the proliferation of wireless nodes in the network lead to new innovations in radio components and signal processing algorithms within the radio unit. This, in turn, allows communication devices to additionally serve as sensing devices. From an infrastructure perspective, such a technology enables communication-centric services, including environment monitoring, network resource optimization and interference management for base stations and industrial Internet of Things. However, the requirements and technical specifications vary depending on the specific application. Nevertheless, the exploitation of full-duplex radio circuits in a radar-like operation for joint monostatic sensing and communications is expected to be a prominent feature in future wireless systems due to the additional position and velocity information it provides to the network, albeit at an incremental cost due to hardware constraints.

In this presentation, we will explore trends in global standardization activities, broader market applications, technical requirements, and fundamental technical challenges by analyzing two distinct use cases, i.e., smart cities and smart factories. We will also examine the integration of sensing and communications for broad market adoption from an industrial perspective.

Industrial IoT (IIoT) is the biggest enterprise market segment, and therefore Industrial IoT was given high priority in 5G standardization. The timeline for 5G and the 4th industrial transformation (Industry 4.0) seemed to align perfectly, so the joint investment in standards and development seemed to make perfect sense. The needs of this vertical were studied very carefully, and requirements to 5G standards were drafted based on inputs from key industrial automation companies. The standout features for Industrial IoT included support for time sensitive communication and 1ms latency together with URLLC features as well as options for non-public networks (NPN).

5G-ACIA published a whitepaper on 5G NPNs in March 2024. 5G NPNs are already used for industrial applications today. When we analyze the different NPN deployment options, we start from real life-type example industrial operation scenarios. Then we present example NPN deployment options that support the use cases, are based on standard technology and in line with the market offering today. From there we discuss the different aspects that affect selecting the deployment option as well.

Now, at the time of early but defining first steps of 6G, when we look at the 5G situation, we learn there is still some way to go to meet some expectations on IIoT specifics. The current IIoT deployments focus on use cases such as connected workers, worker safety and machine digital twins, which mainly do not utilize features specifically designed for IIoT, and many of the networks are still using 4G technology.

This presentation also discusses what the experiences from the marketplace are, what is good and where we still need improvements, and most importantly how we can use the experience going forward to 6G. Based on our experience, we explain why 5G IIoT is taking more time than expected, how standardization should address this learning, and in specific why some of the 5G IIoT requirements are still relevant for 6G standards development and how to phase the work.

Nokia is one of the founding members of 5G-ACIA and Uli Rehfuess will proovide some insightful views on where we on the road towards Industrial 5G are.

According to the latest studies by TÜV, the number of cyber attacks on industrial companies is growing continuously. At the same time, the number of 5G campus networks in industrial environments is increasing. New use cases are combining 5G communication with traditional production technology. In the past, physical isolation of the OT (especially when using wired communication) and network segmentation protected unsecured end devices from unauthorized access. When using the air interface of wireless communications technologies, such as 5G or WLAN, access to connected networks can no longer be protected by physical access controls alone.
This paper presents a PKI based security framework meant to protect the point of connection between the 5G network, company internal IT networks and OT networks. It aims to support companies in securely integrating their IT and OT networks and realizing their Industry 4.0 use cases, by offering automated certificate management for the OT domain. The presented security framework assumes three distinct security domains: the 5G network itself, an OT domain, and an IT domain. The 5G core offers a range of inbuilt security functionality that can potentially support certificate management over the entire operating cycle of an automation component. The IT domain is expected to employ commonly used measures of ensuring IT security within an internal network, e.g. Firewalls, Network Access Control and user authentication and authorization services. While IT networks traditionally focus on confidentiality, availability, and integrity, OT components focus on reliability, authenticity, and compliance with latency limits. The OT domain may feature a variety of end devices that may support only very specific, sometimes outdated, security features, or possible no security features at all. Our framework aims to bridge the gap between the high level of security already present in the 5G and IT domains and the differing levels of security found in existing OT installations.
The implemented security framework is integrated into a multi-access edge computing (MEC) environment and has direct access to the 5G core network. It provides certificate based authentication of devices and users in differing domains, enabling secure communication between domains, e.g. between IT and OT. It also supports secure communication between end devices and the MEC, and among OT devices. Selected Use Cases will be presented to demonstrate how this framework can be used in practice. Typical industrial use cases such as localization and communication between production systems will be showcased.

[The presented Use Cases and security architecture are developed within the research project “PKI in infrastructures for industrial automation technology” (PIA5) founded by the Federal Office for Information Security (BSI).]

From the beginning, 3GPPs vision of ubiquitous communication included the usage of satellite or airborne based network components.
Heading towards 6G we envision the contribution of NTN into the 6G system, IMT-2030 sets some clear requirements incorporating a non-terrestrial, unified network architecture from its inception. Release 17 considered as the start of NTN in 5G targets at enabling non-terrestrial network services. Later releases will enhance the NTN contribution and even if 6G may be an evolution and not a revolution, NTN will play a pivotal role from the advent of 6G.

This presentation will outline the technology evolution from the first NTN up to the anticipated technology evolutions on the path to 6G. The NTN technology starts with transparent mode architecture, incorporates regenerative mode and multi-connectivity mobility scenarios on a mid-term basis, and then looks towards long-term aspects like 3D unified and resilient networks, ultimately paving the way towards “beyond cellular” in a 6G network that includes NTN from its inception.

In addition, we would like to present the evolution of Test and Measurement aspects and how T&M can ensure the successful operation and development of future NTN networks.

Given the rapidly evolving wireless communication environment, the problem of ensuring the security of devices which implement new and existing communication protocols is crucial. As we progress towards 5G, 6G, and beyond, addressing potential vulnerabilities in both hardware and software becomes increasingly important.

In the early generations of cellular networks, there was virtually no security, but the scope of their application was also limited. Today, wireless communication is not only an integral part of modern high-tech society but also a vital element of modern economy. IoT has firmly entered our lives, and nowadays vehicles, trains, and airplanes are online most of the time. However, how does the security of existing modem solutions, which provide such continuous connectivity, measure up to the potential consequences of threats related to their use? If a hacker remotely hacks your smart toaster, you will get a burnt toast, but what if they remotely hack a car or a train?

In our report, we will present a retrospective analysis of the practical security of communication networks from the perspective of end-user modem security. We will pay special attention to the security of modern modems based on our practical experience. We will also discuss the feasibility of a remote compromise of a modern modem and the real consequences it could have. Finally, we will separately address the issue of solving existing problems in the security of end devices that are "online."

By studying security issues and sharing our findings, we aim to provide valuable insights into improving the resilience and reliability of wireless communication systems. Join us to explore the critical areas where security must be prioritized and discuss the necessary steps to protect future communication technologies from emerging threats.

Matter is the new future-proof vendor-agnostic connectivity standard designed for IoT and smart building environments, already adopted by many different setups including alarm sensors, security cameras, or door locks. The standard, maintained by the Connectivity Standards Alliance (CSA) and supported by industry-leading companies, puts a lot of effort in ensuring that only trustworthy devices are admit­ted into the ecosystem. The goal is to prevent attacks where rogue devices join the network, gaining access to privacy sensitive information, or performing disruptive operations.

To achieve its objective, the standard defines a Device Attestation Procedure that relies on digital certificates and private keys deployed on the devices and used during commissioning to prove authenticity and standard compliance. Matter's official threat model highlights the importance of safeguarding this cryptographic material, but how have manufacturers been handling this aspect so far?

This research puts this model under test, and presents a thorough analysis of the protection mechanisms implemented in one of the first Matter commercial sensor available on the market. Our investigation revealed how both hardware and software defenses implemented by the manufacturer can be bypassed, which ultimately allowed us to compromise the confidentiality of the device’s private key. An attacker achieving the same result could potentially create counterfeit devices indistinguishable from genuine certified ones, thus jeopardizing the security and privacy of an entire Matter network.

CO2 sensors are often used in building automation to monitor the quality of the air and to trigger measures to improve that quality. These devices have proved very useful during the recent covid-19 pandemic. They are usually powered using mains or batteries. However, there are use cases where energy autonomy is desired. In some cases, it is also advantageous to transmit the data to a central point, using an appropriate long-range protocol.

CO2 sensor using the NDIR method are among the best in terms of measurement quality and life span. However, that method requires more energy, which negatively impact energy consumption. LPWAN protocols also require more energy than short range wireless systems. All that make it difficult to design a good quality node that measures often and yet runs on harvested energy indoors.

We first analysed the energy requirements of different NDIR sensors that on the market in order to choose the most appropriate. We then used some power management techniques to optimise the power consumption of the node and to make it operate in an office environment using LoRa.

At 350 lux (artificial light) and using a solar cell of 8 cm2, sufficient energy is harvested to make measurements and transmit the data every minute, using the LoRa protocol with SF7.

We will present the challenges of the design, explain how those challenges were solved and show the results.

A Testbed to Identify Vulnerabilities and Secure Wireless Systems in IIoT

The Industrial Internet of Things (IIoT) has revolutionized industries by enabling advanced automation and enhancing data processing capabilities. In addition, using wireless technology in IIoT offers numerous benefits such as flexibility, resilience, scalability, and mobility. However, the increasing connectivity and wireless communications associated with IIoT make processes more vulnerable to cyberattacks. To address this issue, we built a testbed with multiple wireless protocols to evaluate the security of IIoT devices and wireless networks. The testbed allows for identifying and assessing security vulnerabilities and developing and evaluating mitigation strategies, thereby directly impacting the security of wireless systems in IIoT.
Our research began with an extensive review of essential standards and protocols in the IIoT field. We then applied this knowledge to create a unique compatibility stack, including both wired and wireless protocols, that can be directly used by system designers in selecting the most appropriate communication protocols for IIoT applications. While our findings demonstrate the increasing adoption of wireless technologies, they also highlight the fact that very few testbeds cover wireless protocols, and even fewer consider their security aspects.
Our testbed utilized a variety of communication methods prevalent in the industry, such as Modbus, Profinet, Wi-Fi, Bluetooth, WirelessHART, and LoRaWAN. The testbed was placed inside a Faraday cage to avoid any unwanted interference to outside world from security tests. Amazon Web Services were utilized for the cloud infrastructure, incorporating critical services such as AWS IoT SiteWise, AWS IoT Greengrass, and AWS IoT Core. In addition to the current use of a broadband internet connection, we plan to expand the testbed to include 5G cellular networks for remote communications.
We are simulating several potential attack scenarios, including well-known attacks like the Mirai Botnet and attacks specified for wireless such as wireless signal analyzer and smart selective jamming attacks. These simulations are enhancing our understanding and helping us improve the security measures for IIoT devices and wireless networks.
The IIoT testbed we built provides a strong foundation for understanding vulnerabilities and developing effective mitigation strategies that enhance the security and resilience of wireless IIoT systems against evolving cyber threats.

mioty® is a breakthrough wireless technology developed by the German Fraunhofer Institute for Integrated Circuits. It is a worldwide open standard for IoT, offering a low-power wide-area network (LPWAN) solution that overcomes many of the limitations of traditional LPWAN technologies. With its patented telegram splitting mechanism, mioty® divides messages into multiple sub-packages and transmits them at various times and frequencies, ensuring unprecedented robustness, scalability, and energy efficiency.

But how can these advantages be derived from the technique itself in an easy way? An answer to this is the spectral footprint of various radio technologies, and in particular of mioty® compared to other LPWAN technologies. The spectral footprint is a way to measure how efficient the use of the radio spectrum is, just like CO2 footprint is a way to measure the energy efficiency of cars. The smaller the spectral footprint is, the more IoT devices can co-exist in the same radio cell and still achieve high quality of service. A lower spectral footprint also makes a radio technology more robust against other radio signals as it’s less likely to be overlapped (=disturbed).

The observations from spectral footprints of different LPWAN technologies are theoretical but helps explaining the results observed in real field installations. By comparing mioty® with other LPWAN technologies in real scenarios, telegram splitting transfers it’s technique into higher range and reliability of data transmission by using less energy per message. These advantages translate into cost-effective long-term investment, allowing users to reduce capital and operating costs and benefit from a low total cost of ownership (TCO). Hence, mioty is ideally suited for large scale IoT installations like Smart Cities, Utilities (with large metering installations), Industries etc. Due to all advantages that mioty® offers, it is ideally suited to be the new global IoT radio standard.

Most test tasks in the development of a new wireless IoT device are usually carried out directly at the developer workstations or in special laboratories, but not in the actual application environment. As a result, many products and solutions do not really work optimally and error-free in the market launch phase. In addition to commissioning errors, the causes of these practical problems are often completely different environmental conditions and the associated disturbance variables, as well as typical continuous operation problems (e.g. critical memory fragmentation, unexpected restarts, etc.). In practice, the details and causes of such errors can only be diagnosed and rectified in extensive field test phases. This requires special hardware and software configurations as well as context-related test concepts.

Using a typical IoT gateway example with one wireless sensor and one 4G/5G cellular connection to the Internet, the presentation will show how the quality of a new wireless IoT application can be significantly improved through field test phases in the pilot customers' application environments and sophisticated test tools adapted to the respective task. In the example presented, the responsible development team uses debugging-capable remote access via GDB/gdbserver to important key components via a separate out-of-band (OoB) radio connection. The application bridge between the IoT gateway to be tested (device under test, DuT) and the OoB communication link is a special debug and test proxy system. It has a USB or SWD connection to the DuT, an SDR interface for the wireless sensor network and the option of switching the power supply to the DuT on and off. The debug and test proxy also measure electrical parameters (voltage, current). In addition, the debug and test proxy system can run automated monitoring and diagnostic functions to support developers in detecting complex error scenarios. The lecture provides the following two examples on this topic:

SNR/airtime monitoring: Using a periodic signal-to-noise ratio (SNR) measurement (signal-to-noise ratio or signal-to-noise ratio), determine whether the frequency band is of sufficient quality for communication with the environmental sensors and whether the requirements for the respective intended IoT wireless application are met. An SDR-based measurement method is used for this, with the raw data being run through various algorithms to detect anomalies.

System condition monitoring: A context-related parameter set (feature set) is defined that describes the respective system status as precisely as possible within a unit of time (e.g. number of Tx/Rx packets/bytes for all communication interfaces, memory status, CPU utilization, airtime of the WSN and WWAN interfaces, energy consumption, etc.). The parameters are periodically recorded and evaluated by monitoring and classification functions.

Complex buildings such as airports, train stations, and fairs are challenging areas where people struggle with orientation and finding their desired destinations. Often, these orientation problems lead to bad experiences, such as when a family member or even a child cannot be found, or if a connecting flight is missed due to losing time while finding the desired gate.

Fortunately, indoor navigation systems similar to the well-known and widely used GPS outdoors are now available. However, these systems require a high level of expertise for planning and installation and struggle with the necessary scalability when a large number of users are involved.

To address this, Pinpoint developed an Ultra-Wideband (UWB) based, easy-to-install positioning system that hides all the complexity of positioning technology. This allows system integrators and device manufacturers without expert knowledge to design new products with location awareness.
The system uses a decentrally organized mesh network that employs UWB as the radio technology. Within this network, each building satellite transmits UWB beacons and can wirelessly synchronize to 1-nanosecond accuracy using a patented algorithm. UWB-enabled smartphones and positioning modules can receive these UWB beacons to synchronize themselves to the network time and calculate their own position with an accuracy of 30 cm. With this technology, the aforementioned use cases can be realized by integrating the building satellite modules into existing building devices, such as light bulbs or fire detectors, and the positioning modules into objects, such as Automated Guided Vehicles (AGVs), employee badges, or simply by using UWB-enabled smartphones.
