Abstract: Wireless communication is widely used in the field of the smart refueling but making the system ultra-low power is the major concern. In application area like mining and construction site, there is a need to use the non-replaceable low power devices which have more battery life. This paper discusses about the various technologies that can be employed for the wireless communication of the smart refueling and gives the idea in choosing the right technology. Sub-1GHz technology is used in the 866MHz (free frequency band in India and has low spectral pollution) with the proper tool and product to build a wireless module for automatic vehicle recognition (AVR) system. This module will use the data read by the RFID reader and transmit it to the wireless receiver at the terminal giving low power and low-cost solution to attain fast and smooth refueling.

Keywords: Sub-1GHz; low power; Automatic vehicle recognition (AVR).
