As the data acquisition system uses the GPRS network, would there be any worries of interference/restrictions of use in a factory with other machinery, such as switching off mobile phones in hospitals?

There is very little chance that it would cause a problem due to the very low RF power.  The RF Gateway with GSM/GPRS would be located outside any ‘mobile sensitive’ areas.

Does the GPRS network suffer from bad reception? Such as a lack of signal on a mobile phone?

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.
