I will continue on from where we left off with smart meters. The different smart appliances send the messages to the smart meter for reading or for adding up the kilowatt hours used. Now, it's my understanding that in order to read what the smart meters are accruing, the cellphone infrastructure is used and transmits the data to an entity that eventually does the billing. Where cellphone connectivity does not exist, there are remote readers used.
From those two lines of connection, between the smart meter and the building that collects all the information, and the remote reader where cellphone is not available, are there areas of vulnerability there?
