I read about the wifi connected to the Swazm network and there it says that they are trying to solve this, but don't you think about implementing the 5G connection? I know that this technology is still in development, but maybe is it something to take in consideration
Where you red about this and what does it even mean - wifi connected to Swasm

WiFi network is the easiest protocol to hack. Why you talk about 5G if it is not even implemented yet in the real world?
The meters will be integrated with the platform, which means that the use of the SWAZM blockchain will improve the security of the meters and will make it harder for other users to "Hack" the meters or the data which is stored upon them.
