RFID has the potential to address the inadequacy of GPS inside closed environment. While, WSN is capable to extend the communication range between two sensor nodes and GSM supports WSN during network disruptions. Therefore, a new multi-platform indoor and outdoor tracking (ER2G) system that operates at 2.4 GHz based on ZigBee IEEE 802.15.4 standards is presented to overcome the disadvantages present in each technology. The ER2G system with M2M functionalities utilizes API mode to transmit and receive real time data wirelessly and provides switching between indoor-outdoor location and WSN-GSM platform. All tests are conducted in real environments as POC in achieving M2M communication. The performance of ER2G system is evaluated and compared with standalone RFID and ERG system, and it is found to be more efficient than both systems. The results indicate that the ER2G system provides better LOS signal propagation than the standalone RFID by 2.66 % indoor and 26.49 % outdoor. In addition, the switching rate between indoor and outdoor is faster than the ERG system by 0.95 % indoor and 16.47 % outdoor. The proposed algorithm based on AT command request using API mode is able to transmit and receive data by 10.11 % faster than the AT mode. The average tag collection times of ER2G system for TTF and RTF protocols are 14.29 % and 7.14 % respectively, which are higher than the standalone RFID. Furthermore, the average throughput of the standalone RFID is 18.06 % lower than the ER2G system for TTF and 7.09 % higher than the ER2G system for RTF in multi-hops environment with 100 % delivery ratio.
