controls from the user‚ the means of sending signals to the appliances being a mobile phone. 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 messages and LCD to display them. As we are using mobile for sending messages‚ it is easy

The impact of the losses in the system is quite extensive. It is stated that 15% of the board are typically rejected during an early processing inspection along with an additional 5% rejected during the final testing. This results in a production order increase of 25%. 5.What recommendations would you make for a short-term solution to CBF’s
