Purpose: do you want to be a equipment, implement any object within a certain range (motion) displayed on the electronic map (like navigation, unlike the navigation display multiple objects) at the same time, their design: consists of two systems: the transmission and receiving system, to MCU to wireless transmitting module, Gps module of launch system (launch system, the Gps to obtain the latitude and longitude, speed, time and other information, through the microcontroller programming, wireless transmitting module to launch to broadcast), the receive module to single chip microcomputer to electronic map of display system (receiving display system: broadcast information module receives the other position, compiled by single chip microcomputer, then feedback to the electronic map, the electronic map display the received multiple object location information), requirements: 1, the transmission distance is more than 500 metres (obstacles have adapt to the environment), 1000 m; 2, no late fee (the absence of other schemes, then consider using mobile network); 3, the sending and receiving GPS location information must be continuous, real-time updates, please master to give directions, this scheme is feasible? Is there a better solution?

Ok, LORA can now to a few kilometers away Far behind in IOT, a device dozens of pieces a year
