Internet Access in Remote Areas Using NXP Microcontroller and GSM Modem
In India and many developing and under-developed countries, providing internet facility to many school-going students is still a far-fetched concept. In this paper, which is based on the authors' project, they propose a new system which circumvents the internet architecture by using GSM infrastructure to access internet services, albeit on a reduced scale. This can be done by using a GSM Modem interfaced to a microcontroller (NXP in this case.) The command sets of each service offered in the system are integrated in the source code. The GSM Modem is controlled through AT Commands and sends SMS messages to access internet services and receives information in the form of SMS messages. All subsystems in the module are interfaced to the microcontroller.
