The existing electric grid system in Brazil is facing many challenges and this encourages the roll out of smart grid systems to reinforce the existing grid system. In this context, energy companies are seeking for solutions and applications to grow and expand their network improving reliability and coverage. One of the key technologies of smart grid is a two-way communication between smart grid components. Considering that wireless communication outperforms wired communication, it becomes a good option to provide connectivity to smart grid system that covers a wide range of geographical areas. This article presents a successful application of LTE 450 MHz in electric energy sector, which allows remote control of reclosers in an electric distribution network, thus giving a faster fault diagnosis, recovery and maintenance of faulty electric circuits. In comparison to similar solutions, LTE 450 MHz provided a reliable coverage beyond 40 km range.
