Tecnologias de banda larga para assinantes móveis no Exército Brasileiro: comparativo de viabilidade entre o 4G LTE e WiMAX

Abstract

The fourth generation of mobile broadband communication brought the synergy between voice and data, transmitted through IP based data packages. This mean of communication, due to its great support to mobility and information flow, enables a higher efficiency and a new dynamic to the Armed Forces Command and Control (C2). The possibility of real time information from the battlefield, transmission of orders and feedback, improve the situational awareness of the commanders at any chain level. From this perspective, this study had the objective to analyze the Broadband Mobile Communication Systems (4G LTE and WiMax), comparing them by its main characteristics and focusing on a solution for the Brazilian Army mobile networks. The research used military and civilian sources, interviews with telecommunication experts and possible solutions from telecommunication enterprises. Was verified that the LTE has a better availability of equipment and is more suitable to attend the requirements of military operations using systems already available in the market and developed by the massive investment in LTE, in comparison with WiMax Systems. However, a possible acquisition of 4G LTE equipment will require a complementary study to specify the needed characteristics as well as the financial resources involved on the implementation of such network.
