Revolutionizing Healthcare: The Vital Role of IoT Connectivity

  • September 16, 2024

In today’s digital age, technology has transformed every aspect of our lives. Perhaps nowhere is this more evident than in the healthcare industry. The emergence of the Internet of Things (IoT) has paved the way for unprecedented advancements in medical care, revolutionizing how healthcare professionals diagnose, monitor, and treat patients.

IoT devices, whcih have become indispensable connectivity tools for modern medicine, are at the heart of this technological transformation.

What is IoT Connectivity?

IoT now factors into everything from smart home appliances to industrial equipment. But IoT devices need a strong network connection to interact with other machines, transmit data, and engage with cloud-based management platforms. Without that internet connectivity, even the most sophisticated equipment is useless.

In the medical industry, IoT connectivity powers up devices and sensors that collect and transmit real-time data to providers. These devices range from wearable gadgets and smart implants to hospital equipment and medical instruments — all designed to facilitate patient care and improve clinical outcomes.

IoT Connectivity for Medical Devices

So, which healthcare technologies typically require an internet connection? It’s a growing list that includes telemedicine, data sharing, connected health solutions, and devices/systems that enable remote monitoring. Here are a few examples:

  • Telemedicine – Video conferencing tools and remote diagnostic tools allow physicians to perform virtual assessments in real time.
  • IoT Medical Devices – Smart beds, smart IV pumps, and connected ventilators monitor patient conditions; smart dispensers remind patients to take their medications.
  • Medical Robotics – Telesurgery systems enable surgeons to perform remote robot-assisted procedures with precision, via high-speed internet connection.
  • Remote Patient Monitoring (RPM) – Wearables like smart watches, patches for monitoring blood pressure and glucose levels, and home medical devices like CPAP machines all depend on cellular connectivity.
  • Medical Imaging – High-res equipment like MRI and CT scanners use network connectivity to share large files to the cloud or send to specialists for further analysis.
  • AI Diagnostic Systems – Increasingly, internet-based AI systems take on the jobs of analyzing blood work, medical images, and other diagnostics.
  • Electronic Health Records (EHR) – Cloud-based EHR systems allow healthcare workers to securely, seamlessly store and share patient data.

Internet access is also critical to mobile health apps, pharmacy management systems, emergency vehicles, and clinical support/CDSS tools. 

Cellular Hardware + Medical Equipment

To connect reliably to the internet, most healthcare IoT devices need cellular hardware that’s secure, reliable, low power, and broad in coverage. The most common of these include: LTE-M, NB, 4G LTE, 5G, and 2G/3G.

 

LTE-M for Wearables and Mobile Equipment


Wearables, mobile medical equipment, and telemedical portal devices are best suited to long-term evolution for machines (LTE-M) technologies that offer broad coverage and low power consumption. Because LTE-M supports mobility, health monitors and trackers will stay connected even when a patient is on the move. LTE also facilitates two-way communication and works with multiple cellular networks.

NB for Implants and Home-Based Sensors

What about a CPAP machine or long-term implanted device that sends data only intermittently? These devices are a good match for Narrowband IoT (NB IoT) technology. NB is also great for connecting low-bandwidth medical devices and equipment used inside of buildings that have difficulty getting a signal.

4G LTE for High-Resolution Medical Imaging and Video Streaming

Anything that requires real-time video and audio streaming (think of the typical telemedicine platform) needs a 4G long-term evolution (LTE) solution. High-res imaging devices and mobile health clinics also require 4G LTE to ensure reliable transfer of data and a steady connection in just about any location. Additionally, it’s important to note that 4G LTE is often the best match for multiple IoT applications outside of healthcare because of its speed and reliability.

5G for Connected Ambulances and Other Time-Sensitive Applications

For any healthcare application requiring immediate feedback, 5G is the best match. With 5G, hospitals, clinics, and ambulances can transmit data at noticeably high speeds, allowing for quick and reliable communication. Most 5G routers can also connect to multiple healthcare IoT devices. Other uses for 5G include robot-assisted surgery, AI-powered systems that can instantly analyze health data, and emergency vehicles that depend on real-time monitoring. 

2G/3G for Legacy Systems and Areas of Limited Infrastructure

Although many regions have phased out 2G and 3G networks entirely, some healthcare facilities and technologies still depend on these networks, particularly in remote locations. In these places, 2G/3G can work for simple monitoring, SMS alerts, and transmitting small amounts of data.

Overall, LTE and NB cellular technologies strike a good balance between power efficiency, coverage, and costs — especially for home health and remote monitoring uses. But we can expect 5G to be increasingly important for high-powered medical IoT uses in future. 

The Human Side of Healthcare IoT

The ability to facilitate remote patient monitoring is another driving force bethind healthcare IoT.

Traditionally, patients with chronic conditions, or those recovering from surgery, need to visit healthcare facilities frequently for check ups. But in many cases, this can be difficult for sick patients. That’s where IoT kicks in.

IoT-enabled devices like wearable sensors and home monitoring systems make it easier for healthcare providers to track their patients’ vital signs, medication routines, and overall health status in real time — without the imperative to see patients in person. 

These medical IoT technologies not only allow for more proactive intervention, they also enable patients to receive personalized care from the comfort of their homes. In turn,  the convenience of at-home virtual care often leads to greater patient satisfaction and better health outcomes. 

Empowering Patients

Data suggests that over 20 million patients around the world use some type of internet-powered medical device. For those with diabetes, the number is even higher: nearly 30 million American diabetic patients receive continuous glucose monitoring via wearable devices. Smart inhalers and heart monitors add to the numbers.

Aside from being good for business, connected devices are also good for patients’ long-term health.

IoT connectivity plays a huge role in enabling disease detections and intervention. By continuously monitoring patients’ health metrics, such as heart rate, blood pressure, and glucose levels, IoT devices can detect abnormalities or signs of deterioration before they escalate into serious medical conditions.

This proactive approach to healthcare not only prevents complications, it also lowers out-of-pocket costs from multiple office visits. Likewise, this approach empowers individuals to make informed choices and take control of their health.

Optimizing Healthcare Facilities

Beyond patient care, IoT connectivity also enhances operational efficiency. By automating routine tasks, optimizing resource allocation, and providing real-time insights into equipment performance and inventory, IoT-enabled devices are helping hospitals and clinics become more efficient.

For example, connected medical devices can automatically transmit data to electronic health records (EHR) systems, eliminating the need for manual data entry and reducing the risk of errors. This capability streamlines workflows, improves accuracy, and frees up healthcare professionals to focus on caring for their patients.

Moreover, IoT connectivity fosters collaboration and data sharing among healthcare providers, facilitating interdisciplinary care and improving care coordination. Thanks to secure communication channels and interoperable systems, clinicians can access patient data from multiple sources — regardless of location — for more holistic and comprehensive care.

This seamless exchange of information not only improves clinical decision making; it also ensures continuity of care as patients transition between multiple healthcare facilities.

Revolutionary Results with IoT Expertise
