7.6 Conclusions and Possible Improvements

The uplink module performs as expected, meeting all device s peciﬁcations

and fulﬁlling all requirements.

• Due to the modular s oftware approach, it is possible to add or modify

the system without a redesign.

• Possible improvements include the ability to conﬁgure the device locally

(without a computer or mobile phone) through an interactive menu

system.

• It may be useful to be able to bulk SMS conﬁguration changes remotely

and have the module bulk-execute these commands upon uplink establishment.

• The software to communicate with the I

C EEPROM device has not

been completed, however, interface libraries are available and the hardware

is in place. The addition of this IC ensures that the captured data will

not be lost even if the main power supply, the battery backup and the

GSM uplink fail. It is thus another step in ensuring reliable device

operation.
