I started a commercial service of vehicles tracking and fleet managment using GPS GSM/GPRS to send data to my server. I have been front of various problems.
1. The network here in Cameroon is not everywhere.
2. Customers want to identify the driver before allow it to drive the car or truck
3. Customers need to be able to switch between several GSM Networks Availables.
4. Where there is no network we need to store data on a flash memory for future transfer to server.
5. The customers want to know the quantity of fuel the vehicle as consumed to avoid fuel trafric.
6. Be able to do smart stop of the engine when the speed is under a certain value in case of Hijack.
These are the Elementary features of the device.
I have drawed a small diagram to represent my idea. And I need participants to make this dream becomes reality.
