8.8.3 Calculation example
We assume a GPRS rate for data with a 1kilobyte billing matrix, as offered by T-Mobile
and Vodafone as M2M rate.
Usually, GPRS network providers bill once daily, e.g. once a day the sum of all accumu-
lated data since the last billing is rounded to the next billing unit (here: 1 kilobyte).
Example T-Mobile: Contract M2M Connect (Date: September 2005)
and Vodafone as M2M rate.

The following examples show merely the pure data transmission. When a TCP/IP connec-
tion is established via theINSYS GPRS 5.0 serial, data is generated (128 byte). The INSYS
GPRS 5.0 serial will not terminate a once established connection automatically, i.e. the
amount of date for the connection setup may be ignored.
However, the following may occur:

However, the following may occur:
¾
The remote terminal can no longer be reached (power failure in the control cen-
ter, system crash, new IP address for the control center, …)
¾
The GSM/GPRS network breaks down temporarily
¾
The GPRS modem has a power cut
In all cases, the INSYS GPRS 5.0 serial will automatically attempt a new connection setup
to guarantee the availability of the application (attempts in intervals of 20s, 80s, 320,
1280s, 1h, 1h, 1h …).
For the M2M rates, for each (failed) connection setup attempt 1kilobyte amount of data
may be assumed (at a 1 kilobyte matrix); it is therefore recommended to plan a reserve
of 30 to 50 kb up to the according upper limit of the rate.
