So, what is IoMT? In a nutshell, the Internet of Medical Things (IoMT) refers to medical devices that connect to healthcare IT systems through the internet. Keep this concept in mind, as you’ll likely hear about it a lot in the next years.
The global IoMT market is expected to grow at a CAGR of 26.09% till 2034. That’s because digital adoption in healthcare has increased plenty after COVID-19. But scaling these systems introduces challenges most healthcare IT teams weren’t built for.
IoMT systems must handle large volumes of sensitive health data, operate with near-zero downtime, and comply with strict security and privacy laws. Unlike general IoT, medical devices must meet clinical standards, offer real-time reliability, and run on secure, access-controlled networks.
This guide explains what IoMT is, how it works across clinical settings, and how to secure it.
What is IoMT?
The Internet of Medical Things (IoMT) is a network of medical devices, software applications, and health systems that are connected via the internet. These devices collect, transmit, and sometimes analyze health data in real time. The goal is to support faster clinical decisions, reduce manual processes, and improve a patient’s health outcomes.
IoMT includes tools like:
- Wearable heart monitors that stream patient vitals to a cardiologist’s dashboard
- Infusion pumps that auto-adjust dosage and report performance data to nursing staff
- Mobile apps that sync home glucose monitors with hospital EHRs
- Smart pill bottles that alert caregivers when a dose is missed
Unlike consumer IoT, IoMT devices must operate within the regulated industry medical services. They carry stricter requirements for:
- Data integrity – Health data must remain unaltered from device to system
- Uptime – Devices must function with near-continuous availability, especially for critical care
- Interoperability – Devices must integrate with hospital infrastructure like HL7, DICOM, and EHR systems
- Security – Protected health information (PHI) must meet HIPAA, GDPR, or MDR compliance
The 5 core components of IoMT
A functioning IoMT system is an integrated architecture built around five core components:
1. Connected medical devices
These are the endpoints (the hardware infrastructure) that interact directly with patients or the clinical environment.
Examples:
- Wearable devices like ECG patches or blood pressure cuffs for remote patient monitoring
- Implantables such as pacemakers with telemetry
- Smart hospital beds with built-in sensors for weight, vitals, and positioning
- Smart pill bottles that log ingestion events
These devices generate structured and unstructured health data coming from vital signs, timestamps, dosage logs, which are then pushed to edge processors or cloud systems for interpretation.
2. Communication infrastructure
IoMT relies on secure, uninterrupted transmission. This means selecting the right protocols, bandwidth, and network architecture for clinical environments.
Typical stack includes:
- Private LTE or 5G for hospital-wide device networks
- Wi-Fi 6 for in-facility mobility with lower interference
- Bluetooth Low Energy (BLE) for wearable integration
- NFC and RFID for asset tracking and mobile handoffs
- TLS, VPN tunnels, and AES encryption for data in motion
In many hospitals, RealVNC Connect is used to tunnel encrypted sessions across segmented networks. It gives IT admins direct access to device groups without compromising perimeter security.
For example, BIOTRONIK uses RealVNC Connect to boost their support team’s efficiency, eliminate travel time, and offer better patient care.
3. Edge computing
Edge computing allows data processing to occur at or near the source. This reduces latency and dependency on cloud availability. It’s quite literally transforming healthcare, as when it comes to critical care, these milliseconds can be life-saving. Here’s an example:
- A wearable cardiac monitor cannot wait 200 milliseconds for a cloud-based system to detect arrhythmia. In critical scenarios like this, edge computing enables the device to process data locally, identify anomalies, and trigger alerts immediately.
- In remote settings, edge nodes are a must to maintain continuity during intermittent connectivity and keep remote patient monitoring up and running on personnel’s devices.
4. Data storage systems
In the healthcare industry, data must be stored in compliant, redundant environments. This includes:
- HIPAA-compliant cloud repositories
- Encrypted local databases for edge deployments
- Redundant storage clusters for high-availability hospital deployments
- Audit logging integrated with access control systems for reporting and auditing medical care
Storage must accommodate:
- Structured EHR data (e.g., vitals, diagnoses, lab results)
- Device metadata (e.g., firmware versions, error logs)
- Unstructured data (e.g., voice recordings, continuous waveforms)
5. Analytics and integration engines
These platforms turn medical data into action. This can include:
- Clinical dashboards for physicians
- AI-based risk scoring (e.g., readmission probability, healthcare facilities deterioration alerts)
- Integration with hospital EHR systems via HL7, FHIR, and DICOM
- Real-time alerts to mobile devices used by on-call staff in personal emergency response systems
Without consistent and standardized data inputs from connected devices and healthcare organizations, downstream analytics fail.
Essentially, IoMT only delivers value when these components work together. A single unsecured port or incompatible firmware version can break the chain. In healthcare and medical applications, this carries real consequences.
How IoMT Differs from Traditional IoT
IoMT and IoT share a technological backbone. For example, they use networked devices, embedded sensors, and data transmission, but that’s where the similarity ends. If you want to understand the operational, regulatory, and architectural differences between IoT and IoMT, keep on reading about their five core differences:
1. Purpose and clinical integration
IoT systems are designed for consumer-facing automation. A smart thermostat adjusts your home’s temperature. A wearable counts your steps. Interruptions or inaccuracies are tolerable.
IoMT supports direct clinical interventions. Devices must function within tightly controlled healthcare workflows, integrate with healthcare information technology systems, and comply with clinical protocols that can’t afford failure.
Use cases include:
- A telemetry bed that adjusts positioning to prevent pressure ulcers and transmits data every 60 seconds
- A post-surgery patient being monitored at home through a wearable that pushes vitals to a hospital dashboard every 5 minutes
- A connected infusion pump that calculates and delivers medication doses and alerts medical personnel if the delivery rate changes unexpectedly
Such scenarios are part of routine healthcare procedures and require synchronization with software systems, electronic health records (EHRs), and clinical decision support tools.
2. Data sensitivity and flow across providers
IoT data tends to be user-controlled, low-risk, and structured. It rarely crosses systems.
IoMT systems generate high-frequency, high-stakes data that must travel across a multi-party ecosystem, like from patient-facing devices to hospital servers.
This raises key risks like
- Who owns the data? A hospital, the patient, the device maker, or the platform operator? Most hospitals still lack formal policies defining when IoMT data belongs to the provider or patient.
- Transferring data across national or state borders may trigger new obligations under HIPAA, GDPR, or country-specific health data laws.
- If a third-party device fails to log or analyze data correctly, liability could extend to the hospital’s IT team.
IoMT introduces accountability that IoT does not.
3. Architecture and infrastructure requirements
IoMT infrastructure is a clinical asset class. It must support:
- Low-latency communication technologies like BLE, ZigBee, or 5G for real-time monitoring
- Redundant power and failover systems to protect against downtime
- Medical device manufacturers’ compliance constraints around firmware, patching, and remote diagnostics
- Secure, encrypted communication layers for every device that transmits data to a hospital system
PS: RealVNC Connect v8 can remotely access and manage in-hospital IoMT devices without needing a public IP or opening firewall ports, which is something consumer IoT systems aren’t designed to support.
4. Security – from basic encryption to zero trust
In IoT, password protection and basic TLS are considered acceptable.
In IoMT, the attack surface is larger, more exposed, and directly tied to patient safety. Consider:
- 75% of infusion pumps have known vulnerabilities that allow remote access or configuration changes, according to a report.
- Devices frequently run on outdated operating systems with no active patching from vendors.
- Many in-hospital devices were not originally built to connect to the internet, yet are now networked for convenience.
IoMT security must include:
- Role-based access control (mapped to clinician identity systems)
- Device segmentation (each unit isolated from the broader network)
- End-to-end VPN encryption for remote sessions
- Full audit trails for data access, firmware changes, and remote interventions
This is why many hospital systems are adopting Zero Trust frameworks for connected medical environments. Remote access tools must now support compliance logging, two-factor authentication, and access expiration (capabilities provided out of the box by RealVNC Connect’s unified Viewer/Server platform).
5. Interoperability, compliance, and vendor lock-in
IoMT must interface with:
- HL7/FHIR-based healthcare information technology systems
- PACS and medical imaging systems
- Provider scheduling platforms
- Hospital management tools and billing software
- Device log servers for operational efficiency auditing
But device compliance across vendors is rarely guaranteed. Many hospitals struggle with:
- Fragmented firmware standards
- Custom APIs that break on update
- Vendor lock-in that prevents mixing third-party devices
A proper IoMT deployment requires vendor-neutral middleware, remote access platforms that can navigate hybrid fleets, and data normalization pipelines to maintain data integrity across systems.
6. Cost structures and business impact
IoT systems prioritize affordability and ease of use. Most can be deployed in minutes by the end user.
IoMT investments require:
- Clinical validation
- Network hardening
- Policy alignment with healthcare regulations
- Staff training for safe and correct use
Yet the return on investment is measurable.

Real-World Applications of IoMT Across Healthcare Settings
IoMT technologies are now embedded in the core of modern healthcare delivery operations. With the right software provider, IoMT can support both patient care and clinical logistics across the entire healthcare ecosystem. For example:
- In in-hospital IoMT deployments, medical equipment like telemetry beds, infusion pumps, and smart monitors integrate with devices and software systems to deliver continuous monitoring. These tools track health metrics in real time and alert healthcare professionals during critical events, without requiring constant human intervention.
- At home, remote monitoring solutions help monitor patients with chronic conditions. IoMT sensors transmit patient data securely across online computer networks. It empowers providers to intervene early while improving cost control.
- In clinical trials, pharmaceutical teams use wearables to collect data from participants. Environmental sensors are also used in public health programs to monitor air quality and outbreak indicators.
Overall, a connected IoMT ecosystem can reduce readmissions, optimize inventory management, and support smarter medical operations across medical facilities and other healthcare providers. It can deliver significant benefits across the healthcare market, which we’ll explore below.
Key Benefits of IoMT Implementation
1. Improved patient outcomes and safety
IoMT helps healthcare professionals move from episodic care to continuous monitoring and detect clinical deterioration early to respond faster. That’s because devices that monitor patients can stream real-time data into clinical dashboards and alert teams about changes in vitals or mobility.
Smart infusion pumps, wearable ECGs, and connected implants all contribute to proactive care. When integrated into devices and software systems, these tools create closed-loop feedback that supports safer medical operations with minimal human intervention.
2. Operational efficiency and cost control
IoMT reduces waste across multiple layers of healthcare operations:
- Inventory management improves with RFID-enabled asset tracking
- Automated vitals collection reduces the manual burden on medical personnel
- Smart scheduling systems optimize care team utilization
These efficiencies deliver clear cost control benefits, especially in large medical facilities where staffing, space, and equipment must be tightly managed.
3. Data-driven clinical decision making
The value of IoMT multiplies when real-time data is connected to healthcare information technology platforms. These systems use artificial intelligence and predictive analytics to guide interventions, anticipate patient trends through their long-term health monitoring data, prioritize caseloads, or identify population-level risk patterns.
When combined with secure remote monitoring and compliant IoMT security protocols, decision-makers gain accurate, actionable insights at no data ownership cost.
Challenges and considerations for IoMT deployment
ealthcare teams are often dealing with four persistent challenges: system compatibility, data ownership, lifecycle risk, and secure access.
- Compatibility and integration – Many medical equipment vendors use different protocols. Hospitals struggle to connect healthcare information technology systems when devices can’t talk to each other. We’ve seen hospitals manually combine device data and EHRs, wasting hours and increasing risk.
- Data control – IoMT generates huge amounts of patient data. But when that data moves between a device, a software provider, and a hospital server, data ownership becomes unclear. Without clear policies, hospitals carry the legal risk.
- Device maintenance – In our work with IT teams, few have standardized workflows for IoMT security, patching, or device decommissioning. That’s a gap when you consider health insurance portability laws and MDR rules.
- Secure remote access – Without the right tools, IT teams must touch every device in person. Using RealVNC Connect v8, healthcare teams manage thousands of endpoints remotely, across in-hospital IoMT networks and home care devices.
For example, at Southern Ohio Medical Center (SOMC), the IT team now resolves bedside or imaging system issues remotely. They’re saving time while making sure critical services stay available to patients and staff.
“We use RealVNC remote access software pretty much anywhere we can from PCs to servers, to virtual desktops. It’s so light, cost effective and easy to use.” — Ben Littleton, Systems and Network Manager
