Extreme & WBA: Seamless Mobile Future for Telcos
The relentless march of mobile technology continues to reshape the landscape for telecommunications companies.
As the demand for universal and reliable connectivity soars, telcos find themselves at the forefront of innovation, navigating both exciting opportunities and complex challenges.
To gain insight into this dynamic environment, we spoke with Markus Nispel, CTO of EMEA at Extreme Networks, a seasoned expert with more than 25 years in the telecommunications and networking sectors.
Markus’s extensive background, spanning roles in software engineering, data science and innovation management, provides a rich context for understanding the current trajectory of mobile technology.
“I’ve been in the telecommunications and networking sectors for more than 25 years,” he explains, “leading teams in software engineering, data science, data engineering, solution architecture, innovation management and product management.”
His journey through Cabletron Systems, Enterasys Networks and ultimately Extreme Networks, coupled with two significant periods in the United States, has equipped him with a global perspective on the industry’s evolution.
In his current role as CTO of EMEA, Head of the Office of CTO and Head of AI Engineering, Markus’s focus is firmly on the future. “My main focus is recognising future inflexion points in technology, to seize opportunities and mitigate risks,” he states.
He highlights the dynamic nature of the EMEA region, highlighting his work “to help customers think ahead and explore future possibilities while providing strategic guidance for their IT decision-making.”
His recent initiative to build the Office of the CTO and lead its innovation incubator demonstrates his commitment to anticipating and preparing for key shifts in the technological landscape.
“My mission is to anticipate and prepare for key shifts in society and technology,” Markus affirms. “It’s my job to stay attuned to emerging trends, markets and challenges to provide customers with expert insight to navigate and succeed in our rapidly evolving world.”
Advancing mobile connectivity with openroaming
A significant aspect of advancing mobile technology is creating seamless and secure connectivity experiences. Markus highlights Extreme Networks’ involvement in this crucial area through membership in WBA OpenRoaming.
“Extreme Networks is a member of WBA OpenRoaming, a roaming federation service enabling an automatic and secure global Wi-Fi experience,” he explains. “Together, we’re helping them deliver reliable, high-speed connectivity around the globe.”
OpenRoaming offers a revolutionary approach to Wi-Fi access. “Specifically, we’re providing support for OpenRoaming, an innovative technology that offers seamless, secure Wi-Fi access without the hassle of captive portals or manual password entries. Instead, OpenRoaming gives users smooth handoff from any number of cellular networks to Wi-Fi, so they get guaranteed, uninterrupted connectivity.”
In an increasingly online world, having this capability is paramount for delivering next-generation consumer experiences across diverse environments, supporting initiatives like remote work, remote learning and smart cities. The ease of use for consumers is a key advantage. “All they have to do is install an OpenRoaming profile on their device’s operating system. Once installed, they can access any WBA OpenRoaming SSID worldwide.”
By making connectivity more ubiquitous, seamless, accessible and secure, Markus believes the technology “will help foster new use cases for both consumer and industrial applications.”
Navigating the challenges of the infinite enterprise
While the potential of mobile technology is immense, the journey has its hurdles. Markus points to the ongoing challenges in ensuring secure and reliable connectivity for what he terms the 'Infinite Enterprise'.
“Even post-pandemic, the industry is still navigating some challenges in ensuring secure and reliable connectivity for the Infinite Enterprise,” he notes.
The increasing globalisation of businesses and the proliferation of devices across dispersed environments is straining traditional network models. The rise of remote and hybrid work, coupled with growing cloud adoption, further complicates enterprise networking.
Security in evolving environments is also a significant concern. “For one, remote networks can be less secure than those on main campuses and remote workers might be more vulnerable to social engineering attacks," says Markus. "Together, this can lead to increasing exposure to cyber threats.”
Hybrid work models present unique challenges as companies strive to provide a consistent, reliable and secure networking experience for all employees, regardless of location.
Markus believes OpenRoaming offers a valuable solution in this context: “In this context, OpenRoaming stands out as a valuable solution. It allows users to connect seamlessly across various networks without compromising security or compliance.”
He highlights the robust security features embedded within the technology: “For example, the technology uses TLS encryption, safeguarding user data from unauthorised access while following GDPR practices. It further leverages existing security protocols, like Passpoint, RADSec and standards 802.1x and 802.11i, to ensure network security without compromising user privacy.”
Furthermore, OpenRoaming can be integrated with other security measures like network segmentation and a Zero Trust architecture, providing a layered approach to safeguarding data and access.
The future landscape of mobile technology
Looking ahead, Markus envisions a future where universal Wi-Fi connectivity forms the bedrock of the Infinite Enterprise, asserting: “I believe ubiquitous Wi-Fi connectivity will be the cornerstone on which we’ll build the future of the Infinite Enterprise."
He also highlights the critical role of modern Wi-Fi technologies, such as Wi-Fi 6E and Wi-Fi 7, alongside OpenRoaming, particularly for remote and hybrid work environments: “Together, these technologies will provide new capacity and performance benefits and unlock new use cases, like IoT, AR/VR, for example. I anticipate that enterprises will strategically integrate other purpose-built wireless technologies into a unified security and operational framework.
Beyond connectivity enhancements, Markus is keenly observing the potential of digital twin technology in networking: “I’m paying close attention to the future of digital twins applied to networking. By predicting changes in a virtual world before deploying them in the physical world, digital twin technology can help make networks more reliable and efficient.
"We’re just at the starting ground of the technology and I believe it will unlock a wealth of new possibilities in mobile technology.”
The insights from Markus paint a compelling picture of the future of mobile technology for telcos. The drive towards seamless, secure and universal connectivity, typified by initiatives like WBA OpenRoaming, aims to transform user experiences and unlock new applications.
While challenges around security and the complexities of the Infinite Enterprise persist, innovative solutions and the continued evolution of technologies like advanced Wi-Fi and digital twins offer promising pathways forward. For telcos, staying attuned to these developments and embracing a forward-thinking approach will be crucial in navigating the dynamic and transformative landscape.
