Most deployments use the Ethernet or a Wi-Fi connection to the local area network as the doorway to manage the cloud connection. If using the local area network is not feasible, then a cell modem can be integrated into the gateway to leverage cellular connectivity to connect back to the cloud. The LTE CAT-M1 and/or NB-IoT service connections can be a cost- effective egress technology for lower data rate applications. Maintaining a secure connection across all the technologies is critical, specifically for a gateway in use for medical application or data gathering. There are several popular cloud service providers available in the market today including Amazon, Microsoft Azure, and Google. These providers offer secure connections back to the cloud and enhanced security to protect the data while it is in the cloud. If any patient data is transferred or stored, the cloud service must be HIPAA-compliant to meet the privacy security compliance requirements. The previously-mentioned providers do offer HIPAA-compliant cloud hosting as an additional feature. They also offer software connectors such as Amazon's Greengrass or Microsoft Azure IoT Edge that can be run on the gateway to manage secure connections back to the target cloud service. With these connectors, you can use familiar languages and programming models to create and test your device software in the cloud and then deploy it to your devices. The cloud connector can be programmed to filter device data and only transmit necessary information back to the cloud. You can also connect to third- party applications, on-premises software, and other services with cloud connectors. Several gateways can come bundled with the cloud connectors already active. They also can support programing languages such as Python to enable fast integration of your software application. Leveraging cloud connectors and high-level programming languages enables rapid prototyping of applications and collecting and transmitting target data into the cloud. Some applications can be up and running and transferring sensor data into the cloud within minutes. Gateways accomplish several tasks: • They collect many types of vital information – sensor data, device status and location, serial readouts, and machine status… just to name a few. • They help various sensor protocols and technologies (such as Wi-Fi, Bluetooth, cellular, serial ports, and Ethernet) communicate to one another. • Process the collected data before sending it on to the cloud. Not only does a gateway provide rugged connectivity with a variety of interfaces, it accomplishes this while maintaining high levels of security. Conclusion Choosing the correct connectivity choice for your medical device/medical environment and IoMT applications is a complicated, yet vital, decision to make. The more you understand the concept of IoMT, connectivity technologies, market trends, and your own healthcare environment and requirements, the better prepared you will be to make these decisions.
