This project is an implementation to the idea of the wireless communication between a mobile phone and a microcontroller. Our administrator uses a simple GSM based handset for sending messages to different display stations which are located far away from him. The GSM modem used at the receiver end is used to receive the

Anatomy of contemporary GSM cellphone hardware Harald Welte April 16‚ 2010 Abstract Billions of cell phones are being used every day by an almost equally large number of users. The majority of those phones are built according to the GSM protocol specifications and interoperate with GSM networks of hundreds of carriers. Despite being an openly published international standard‚ the architecture of GSM networks and its associated protocols are only known to a relatively small group of R&D engineers

development of a GSM based power management system. This system allows monitoring and control power consumption by household appliances. The GSM technology is well deployed in most developed countries due to its features like easy interfacing with appliances via radio frequency‚ accessibility at remote area. In this paper‚ software and hardware were developed. The software allows the user of the system to request for an action from the hardware components. The micro-controller is connected with GSM and relays
