I agree with all classmate.To collect health record data from people in various areas and transmitting it to the MOPH computer system, a combination of networks might be used.As Soe Htike and Panyada mentioned, using wearable devices could transmit data to local collection points through PANs. Then local collection points could be connected via LANs or MANs to gather the data and then transmit it to the central MOPH computer system using a WAN. But to use multiple of networks might has some limitation such as data transfer speeds and data security needs.
