I agree with the way of using PAN and LAN networks in the local area as my classmates mentioned above. After the LAN network, I consider that those data will be uploaded to district level office through MAN and those data from all locations in the area will be collected and verified. Finally, those data will be shared with the central level through the WAN network. But if the internet is available in remote areas of the country, clinic data will be uploaded to the district level using WAN network without MAN in between. MAN network setup is quite an expensive investment. Thus, I would rather recommend installing WAN network to cover certain areas of the country with good investment in internet security and data protection tools.
