Abstract
The proper choice of the radiation characteristics of antennas used in LTE terminal is of vital importance, requiring a judicious analysis with appropriate tools to evaluate system performance. This chapter evaluates the 450 MHz LTE system performance with different terminal antennas. The evaluation environment is carefully configured in a system-based simulator, which takes into account the ANATEL and 3GPP standards, and the characteristics of commercial antennas and the geographical distribution of terminals in rural areas. Results show that the use of directional antennas can improve cell throughput from 14 % to 90 % compared to the use of omnidirectional antennas. Moreover, terminal throughput at the edge of the cell is improved by up to 10 times using directional antennas with the same gain as that of omnidirectional antennas.
