SIM Card
For using the MBT1GRS a SIM card of a GPRS mobile network provider is
necessary. It is to verify that the radio network of the respective provider is available
at the point of installation and that the signal strength of the network is sufficiently
high.
Additionally, the following parameters of the SIM card must be known, so that the
GPRS Receiver Battery can be configured correctly:
x PIN of the SIM card
x APN of the GPRS network of the mobile network provider (access point name)
x User name and password for the APN of the mobile network (if necessary)
The configuration software of the GPRS Receiver Battery contains a list of worldwide
used APN for most mobile network providers. If the correct APN is not found there,
the mobile network provider must be contacted.
Cost of the Mobile Network Connection
The monthly cost of the mobile connection of the GPRS Receiver Battery depends
heavily on the tariff of the used SIM card and will only be roughly treated here.
In general a data volume dependent tariff with small data blocks (e.g. 10 kB or
100 kB) or a flat rate tariff should be selected. The GPRS Receiver Battery usually
transmits between 10 kB and 250 kB per FTP data upload. Usually, the monthly data
amount is between 2...3 MB, therefore, a volume dependent tariff with an inclusive
volume of 5 MB should be the best solution in most cases.
Since the GPRS Receiver Battery is also able to send SMS, a tariff including a low
SMS price is to be preferred.
FTP Server
The received radio telegrams of the consumption meters are transmitted by the
GPRS Receiver Battery to an FTP server. Therefore, an adequate FTP server must
be provided. For configuring the FTP server connection the GPRS Receiver Battery
needs the following parameters:
x FTP server name
x User name and password for the FTP server
x Directory to which the received radio telegrams are uploaded
x FTP port number (usually always 21)
