Un verre innovant au service de la durabilité et de la technologie

Spécialiste de la production de verre depuis longtemps, AGC Glass Europe a pris le virage du 21e siècle à pleine vitesse, grâce à des innovations qui combinent

Ayant une longue tradition de verrerie en Belgique, depuis plus de cent ans, AGC Glass Europe s’impose comme un leader en innovation verrière. Fondée en 1961 sous le nom de Glaverbel – né d’une fusion des deux producteurs de verre belges, Glaver et Univerbel, l’entreprise belge a rapidement marqué l’histoire du verre plat en implantant la première usine de production fl oat en Europe continentale. Aujourd’hui, AGC Glass Europe produit, transforme et distribue du verre plat pour la construction, l’automobile et l’industrie high-tech. Avec plus de 100 sites industriels et 13 000 employés à travers l’Europe, l’entreprise fait de l’innovation son moteur de croissance. «Nous avons toujours cherché à dépasser les standards du marché pour développer des solutions à forte valeur ajoutée», explique Jérôme Goubau, Director Advanced Solutions chez AGC. Parmi les innovations récentes, trois technologies se distinguent particulièrement: FINEO, WAVETHRU et WAVETRAP.

Une nouvelle génération de vitrage isolant, alliant performance et esthétisme

FINEO représente l’avenir du vitrage isolant. « Dans dix ans, ce sera la norme », assure Jérôme Goubau. Contrairement au double ou triple vitrage classique, FINEO intègre une fi ne couche sous vide entre deux lames de verre, espacées de seulement 100 microns. « Ce procédé réduit fortement
la transmission de chaleur et de sons », détaille-t-il. Son avantage principal?  Une isolation thermique comparable à celle d’un triple vitrage, tout en étant beaucoup plus fin et léger. « Cela permet de préserver l’esthétique des bâtiments classés, où les fenêtres modernes trop massives ne peuvent être installées », explique Jérôme Goubau.

L’innovation ne se limite pas à la performance thermique. «€Nos vitrages sont recyclables à l’infi ni et off rent une durée de vie de 60 ans, avec une garantie de 20 ans », souligne-t-il. Produite en Belgique, la technologie FINEO a nécessité l’écriture de nouveaux standards de production et de certification, un défi relevé avec succès par AGC. Aujourd’hui, FINEO équipe déjà des bâtiments emblématiques comme le Kanal à Bruxelles ou l’aéroport de Stockholm-Bromma. «Nous avons lancé une première ligne de production en 2019, et nous allons la multiplier par quatre d’ici 2026 pour répondre à la demande croissante», annonce Jérôme Goubau.

Cette évolution technologique s’accompagne également d’une forte ambition écologique. «L’utilisation de FINEO permet de réduire l’empreinte carbone en allégeant les structures et en améliorant l’efficacité énergétique des bâtiments, ajoute Jérôme Goubau. C’est un produit qui répond aux exigences des rénovations patrimoniales tout en apportant des solutions modernes. De plus, le partenariat avec Panasonic a permis d’industrialiser et de perfectionner le procédé, garantissant ainsi des performances optimales et une production maîtrisée.»

Améliorer la connectivité sans compromettre l’isolation

L’innovation chez AGC ne s’arrête pas à l’isolation thermique. La technologie WAVETHRU a été développée pour répondre à un autre défi moderne : la connectivité dans les bâtiments. «En emménageant dans notre siège de Louvain- la-Neuve, nous nous sommes rendu compte que les couches métalliques des vitrages, indispensables pour une bonne isolation, atténuaient fortement les ondes radio et le réseau mobile», se souvient Bernard Monville, responsable pour WAVE chez AGC. Pour résoudre ce problème, l’entreprise a créé WAVETHRU, une technologique laser qui permet de traiter ces couches d’argent sur une zone limitée du vitrage et de créer une grille microscopique invisible à l’oeil nu, permettant aux ondes de traverser tout en conservant les propriétés isolantes et esthétiques du verre.

Les technologies WAVETHRU sont déjà intégrées dans des bâtiments tels que les agences de certaines banques, les stations- service Bruno en Flandre ou encore les espaces de coworking Silversquare à Bruxelles. « Le principal défi reste de faire connaître ces innovations », reconnaît Bernard Monville. Grâce à un traitement au laser, WAVETHRU peut être appliqué sur des vitrages existants, une solution pratique et économique pour améliorer la connectivité sans installation complexe. «Dans dix ans, ces technologies feront partie des standards du marché, au même titre que le Wi-Fi ou la fi bre optique», prévoit Bernard Monville.

Un bouclier invisible pour la cybersécurité et la confidentialité

Mais AGC a aussi développé l’inverse : WAVETRAP. « Nous avons reçu des
demandes pour des vitrages capables de bloquer complètement les ondes, notamment pour des entreprises soucieuses de leur cybersécurité », explique Bernard Monville. Cette technologie permet de créer des espaces hautement sécurisés, empêchant toute fuite de données ou espionnage via les réseaux sans fi l. « Jusqu’ici, on devait utiliser des bunkers sans fenêtre, peu confortables. Avec WAVETRAP, on combine sécurité et lumière naturelle. » Cette solution séduit déjà des  entreprises sensibles aux cyberattaques. « Nous sommes en train de créer une véritable barrière physique contre le piratage, sans impacter le confort des occupants. » WAVETRAP répond également aux besoins grandissants de confidentialité. « Nous avons même conçu des solutions spécifiques pour des hauts dirigeants et certaines institutions gouvernementales », révèle Bernard Monville. « L’intérêt pour ces technologies ne cesse de croître, notamment dans un contexte de préoccupations accrues en matière de cybersécurité et de protection des données sensibles. » Enfin Jérôme Goubau conclut : « Nous ne nous contentons pas de suivre les tendances, nous les créons. »

Artificial Intelligence is on the lips of everyone at the moment and the exhibitors and attendees at MWC 24 were no exception.

One particularly engaging and inspiring talk was given by Tim Höttges, CEO of Deutsch Telekom. He stated: “Nothing has affected everyone, every business model, and the way we are operating and processing, more than AI”.

Endless Gains With AI

Research from Accenture has shown that with the same input productivity gains can be increased and output maximised by up to 37% when using AI.

But it is not just about cost savings. AI can help an operation to be more energy efficient, ensure higher quality, increase network stability, better harness predictive maintenance and enhance customer experience.

Mr Höttges stated there are endless gains in the ways customers can be served with AI. He explored how we can be takers, shapers, makers, and facilitators. You can be a taker by using what is there, you can be a maker by shaping what exists, you can then build using skills from AI and the cloud to become a facilitator.

Deutsch Telekom has established a competence center of 500 AI experts developing products that support smarter ways of working. When it comes to chatbots, AI has helped create more fluid conversations and better quality answers that has improved first call success by 50%. AI is helping answer employee HR questions, improve the productivity of fiber build out planning by as much as 75%, respond to external technician questions, identify network capacity demand, create energy savings, and identify malware.

AI is here to stay Mr Höttges concluded.

Growth Opportunities

It was also interesting to have greater discussions at MWC around the use of augmented reality demonstrations and see the growth opportunities for Open Radio Access Network (Open Ran) and private networks.

Open Ran is a network infrastructure that enables greater choice and flexibility in telecoms supply chains to help improve diversity in the supply chain. It allows suppliers to build and improve their networks using different bits of technology. A private network is secured and isolated from public internet. It allows authorised devices and apps to connect and exchange data with one another. Businesses often use private networks to create local area networks, which offer secure access within a defined geographic location. However, making a network private can be costly as well as complex to design and scale. While it is easy to add a device there still needs to be a dedicated infrastructure in place to support increasing demand.

Most providers of audit tools (Keysight, RS, Anritsu, …) and performance platform (OOKLA and opensignal) have extended their measurement capabilities to offer a global connectivity view for all technology. They now map 5G latency, WIFI6, and 4G and 5G signal strength to give a clear overview of the network capabilities. It is expected that this will ease the deployment of 5G use case.

Tackling challenges 

However, there are challenges with using higher frequencies for mobile networks, as these signals have difficulty penetrating buildings. The market is actively exploring solutions such as installing repeaters or distributed antenna systems (DAS) in all buildings. Additionally, there is growing interest in utilizing millimeter wave (mmWave) bands to ensure high network capacity. Another area of interest is reconfigurable surfaces, with demonstrations of technologies like Reconfigurable Intelligent Surfaces (RIS) being presented by companies such as NTT Docomo Lab and KT Telecom. These technologies aim to improve signal distribution both indoors and outdoors, as well as in transportation settings like aircraft. 

In fact, Qualcomm presented on its booth how the capabilities of our WAVETHRU solution have been explored at its 5G mmWave technology testbed in San Diego. They investigated how it drives consistent connectivity. Using our easy-to-install retrofittable glass surface treatment solution the propagation of 5G mmWave technology was enabled in challenging areas.

The future of connectivity outside and inside buildings and in cities is something big players such as NTT are focusing their attention on. They are exploring the use of higher frequencies but these can be more difficult to evenly deploy. Signals can also be delivered and distributed via femtocells, RIS and internal DAS systems. AGC offers some versatile and effective options in the form of WAVETHRU and WAVEANTENNA.

Sustainable Steps

The works on developing WAVETRAP, the specialty glass, first started roughly 2.5 years ago. It was developed as a team

Discussed too, was network sustainability. GSMA, a global trade body representing mobile network operators, has taken significant steps toward promoting sustainability with the creation of the Sustainability Assessment Framework. Its primary purpose is to evaluate and understand operator efforts related to social and environmental sustainability within the mobile industry. The framework aims to provide a comparable and leading-edge assessment of sustainability practices. It examines the performance of mobile network operator (MNO) operations and considers their interactions with society. However, while it looks at data about BTS consumption there is no information on DAS or repeater consumption. This could present some exciting opportunities for our WAVETHRU solution.

All these topics, and more, featured in many of the conversations were had during our packed agenda of meetings at our dedicated desk in the Belgium pavilion. Attendees were keen to explore how our solutions including WAVETHRU, WAVEANTENNA, and WAVETRAP can help ensure consistent and reliable connectivity in increasingly technologically advanced environments.

Introduction about the mobile network

In order to distribute the mobile signal the operators place a series of base stations on the territory. These antennas emit signals for 2G/3G/4G/5G technologies in several frequency bands ranging from 800MHz to 6GHz. The mobile phone antennas are distributed evenly over the territory to ensure a homogeneous coverage.

Operators use low frequency bands and high frequency bands to distribute the signal. The low bands are used to cover the territory, they propagate better and further but the associated quality of service is low and the number of users that can be addressed is lower, the high bands as for it propagate less well but give a better quality of service and allow to address more users. In terms of signal propagation, the signal from the base stations propagates like sound, the further away from the source the lower the signal.  The higher the frequency the stronger and faster the attenuation.

Operators size their network to have an acceptable signal strength outside and inside buildings. Operators combine low frequency and high frequency approaches to provide mobile coverage that can address enough users outdoors and indoors. In their design a reasonable attenuation of about 10dB is taken into account for buildings.

At the technology level, several technologies coexist at the same time.

Image3

Impact of envelope attenuation

Mobile equipment requires two important elements : signal strength and signal quality. Below a certain threshold, the mobile equipment does not detect any signal and does not work anymore.

Image4

Coverage problems can occur for recent buildings that strongly attenuate mobile waves (attenuation < 30dB). In this case the building is out of the assumptions of attenuation used to size the networks used by operators and problems may appear.

Image5

In this type of building the outdoor signal is good, but inside the signal is weak and at the limit of sensitivity of phones and often available only in low band. This translates for the end user into :

  • NO signal available or only very close to the windows, once the user moves inside the building the signal fades and the phone cuts out
  • – A signal only available in the low band, i.e. a frequency used for coverage that can serve a limited number of users. During peak hours these bands can be saturated and the service can stop.
  • A signal available only in old technologies (2G/3G) that offer a very limited service (low quality apple)

Why do my calls stop?

A call can stop for several reasons

  • either the signal level goes below the sensitivity threshold of the phone, this can happen for example in buildings that are highly hermetic to mobile waves
  • or because the network is saturated and there are too many users, for example if my mobile phone is on a low band during the rush hour periods typically these bands are more quickly congested and the network can eject the users with a weak signal in order to force them to connect on another station and free capacities for the others
  • or because the phone is constantly changing technology because no signal is dominant and strong enough within the building.

Why can’t the person I’m talking to hear me or why does the communication stop in the middle?

Communication systems work in two directions, there is a downlink and an uplink. For a communication to be established, both links must be established in a reliable way. On the other hand, mobile systems constantly adapt their power according to the quality of the communication channel, whether it is at the base station or the GSM. The base station is more powerful than the mobile. The mobile is limited in power for health reasons.

In buildings with high attenuation, the uplink from the mobile will be the first to be degraded because of the limited power of the phone. In this type of building the signal from the base station is able to get in but the cell phone is not able to send its signal to the base station even though it is transmitting at full power. As a result, the end user can hear the caller but cannot answer.

What is a Faraday cage?

A Faraday cage is a metal enclosure that prevents certain electromagnetic radiation from entering or leaving the enclosure. The cage was invented in the 19th century and has a variety of applications in everyday life to protect sensitive electronic equipment or people. For example, Faraday cages are used in medical settings to prevent radio signals from entering the room and interfering with equipment, or in kitchen microwaves to trap microwaves inside the machine so they heat your food and don’t escape.

A Faraday cage is made of any electrically conductive material. This cage can be made of wire mesh, metal sheets or wire coils. It can be any shape, such as a box, sphere or cylinder, and any size, from extremely small to extremely large. Faraday cages can be quite complex or very simple, ranging from a shoebox to an entire building.

In the building sector, recent buildings behave more and more like a Faraday cage, i.e. they strongly attenuate the mobile waves present outside.

This phenomenon is due to the fact that the materials used to build the facades, i.e. walls, insulation, glazing, contain more and more metallic elements. The walls contain metal reinforcements, the insulating panels are made with PU deposited on layers of aluminum and the glazing contain metal layers.

Concerning glazing, it is interesting to note that currently all glazing on the market contain one or more invisible metallic layers in order to obtain high thermal performance. These layers allow to keep the heat and avoid overheating in the building. All these metallic coatings stop mobile waves.

What is a good mobile connectivity in the end?

A good mobile connectivity is a signal strong enough to be above the sensitivity thresholds and a network sized to serve all users.
