There is always a risk that you cannot get a GSM/GPRS connection but very rare that we cannot get a network provider with a signal. However, in the future, (3 - 6 months) we will be able to get data to the web via a 'black box' that sits on the clients computer network (LAN) utilising their current internet connection.
Data is stored in an SQL database per customer and customers can obtain data via the web site or a CSV export can be enabled. There is no method for customers to directly access the database.
Public network access over http is encrypted using SSL Devices connect over a private IPSec VPN and we have our own private APN with the network suppliers.
