I have the same views with all of your discussions on using different networks for transmitting data to MoPH and they all make sense. I only think the choice of the network depends on the system design and the internet availability of the people. I wonder, like “Poh”, if PAN to WAN is a direct option for sending data to MoPH with designated access authorities. This would allow real-time data, but it might cause transaction overloads in the system. Another consideration is for those areas with no internet access, the people can only send the message directly to the local level (e.g. township) through LAN, and then the local level sends the combined data to MoPH’s computer system through WAN network. This would be undertaken through data review at the local level, but it might raise privacy, confidentiality, and time issues.
