Vodafone IoT surpasses 200 million global Internet of Things connections with a heart monitor standing as the milestone product. To celebrate the achievement, we spoke with Erik Brenneis, CEO of Vodafone IoT, about what this means for the future of connected healthcare. From telesurgery to diabetes management and iSIM-enabled devices, he reveals how IoT is transforming patient care, bolstering security and laying the groundwork for a secure, scalable and intelligent ‘Economy of Things.’
Congratulations on reaching the 200 million IoT connections milestone – that’s a huge achievement! The milestone device was a heart monitor, highlighting IoT’s growing role in healthcare. Where do you see the most exciting opportunities for expanding IoT’s impact in health and patient care over the next few years?
The most futuristic and exciting developments in healthcare IoT are those in areas like telesurgery. The idea that a specialist surgeon could operate on a patient hundreds of miles away, in real-time, using precision robotics is nothing short of extraordinary. While the work in that space is undeniably impressive, in the immediate future, the main benefits of IoT in healthcare will be in broader patient monitoring use cases.
Global healthcare systems are under significant pressure, managing ageing populations and an increase in chronic illness. This generates enormous costs and consumes a huge amount of specialist clinicians’ and carers’ time. IoT can play a significant and immediate role in minimising these challenges through a combination of remote patient monitoring, wearables and telecare services. For instance, connectivity solutions for diabetes management devices can and are helping millions of people better manage their condition, improve their quality of life and keep them out of the hospital.
So, I expect further advances in patient monitoring to be at the forefront of healthcare development, improving patient outcomes and reducing costs.
As IoT expands into sensitive areas like healthcare, how is Vodafone addressing public concerns around data privacy, security and trust in connected medical devices?
Data security is an essential part of connected healthcare, protecting confidential and often sensitive patient information. Quite rightly, market regulation and compliance is stringent and the industry demands a high level of cybersecurity to ensure that data remains secure.
Vodafone’s Managed IoT Connectivity Platform, which is used by our customers to manage their IoT SIM estate, offers multiple robust security methods, including two-factor authentication, strong passwords over HTTPS and separate IoT traffic from the public internet. All data is encrypted across our mobile networks, with optional end-to-end application-layer encryption for medical devices, ensuring device authentication and protection of sensitive data.
Vodafone’s use of iSIMs sounds like a major leap forward in simplifying large-scale deployments. Can you share how this integration is already streamlining operations for industries like smart buildings or logistics, and what that means for the future of scalable IoT?
The iSIM is a really exciting new technology development and arguably the next big advancement in IoT deployments as a whole.
Essentially, the iSIM does the same job as a normal discrete SIM, controlling access to networks with the same levels of security. However, an iSIM is completely incorporated into the silicon design of a device’s chip, which makes it possible to manufacture IoT devices with fewer electrical components. This makes them smaller and more power efficient, lowers the manufacturer’s production costs and the carbon footprint. It will make whole new applications possible. For example, in logistics, smart labels used for packaging could help keep track of delivery timelines, inventory and tampering.
Moving back to security and healthcare, the embedded nature of an iSIM makes it virtually impossible to access or remove physically, as well as creating the basis for highly secure, long-lasting and compact medical devices iSIM also provides multiple-layer protections around the data accessed by these devices, meaning we can precisely control the services each iSIM can access within a healthcare organisation. iSIM also incorporates an internal layer of security with the Tamper Resistant Element – this ensures the safeguarding of confidential data and cryptographic operations.
Despite the rapid growth, what are some of the main challenges still facing IoT adoption—especially when it comes to integration with legacy systems in healthcare or critical infrastructure?
The biggest challenge facing IoT adoption is how to make it simple and fast to establish a secure and reliable connection to a device, and then ensure that connection remains available, wherever the device is.
For people with chronic conditions, for example, connected health systems have become life-changing, enabling them to travel and enjoy holidays abroad while staying safely monitored. But no matter where you are in the world, staying connected is non-negotiable.
To tackle this, Vodafone IoT offers a range of network services that allow devices to roam seamlessly between networks, including dedicated low-power wide-area networks (LPWAN).
While WiFi might appear to be a convenient option for IoT device connectivity, it creates operational and security challenges. Devices must repeatedly log into new networks when they change location, increasing the risk of dropped connections and inconsistent performance. In mission-critical environments like healthcare, that’s a risk too great to take. Cellular IoT connectivity removes these barriers, offering stable, secure and truly mobile connections that healthcare applications can depend on.
You’ve mentioned the rise of the “Economy of Things” where connected devices can securely interact and even trade. What sectors are you most excited to see evolve next, and how is Vodafone positioning itself at the forefront of this new digital economy?
The economy of things allows ‘Things’ to autonomously interact and even pay for services. From a healthcare perspective, the economy of things technology we’ve developed provides an even higher level of authentication between devices, making them simpler to set up and more secure to operate.
In the future, the economy of things could be used to order and pay for prescriptions and medical consumables automatically or connect patients to their care providers for remote clinical consultations.
