This data collection requires the use of multiple types of networks for processing.

Firstly, participants use PAN (Personal Area Network) to transfer blood pressure data from wearable devices to their mobile phones, tablets, or laptops via Bluetooth or Wi-Fi. The advantages of PAN include reduced network conflicts and its user-friendly simplicity, requiring minimal technical skills for usage. However, PAN’s drawback is its limited coverage area, which is suitable for smaller regions.

Secondly, the collected data needs to be transferred to the research team at the hospital. In this step, the research team gathers data from individual participants and organizes it in a specific format before sending it to the MOPH (Ministry of Public Health) for further analysis. This step uses LAN (Local Area Network) due to security and privacy concerns, as LAN operates solely within the hospital network. However, the downside is that LAN restricts external access, which can be inconvenient if the research team needs to manage the data remotely or work from home.

Finally, once the data is thoroughly organized, the research team requires WAN (Wide Area Network) to send the information to the MOPH. WAN offers the advantage of long-distance telecommunication, facilitating data sharing regardless of the geographical distance between the hospital and the MOPH. Nonetheless, there’s a risk of unauthorized access to the data, given its inclusion of participants’ private information. Therefore, the research team must implement password protection to ensure restricted access and share the data only with authorized personnel.
