Comparison of LTE Coverage Areas in Three Frequency Bands

Abstract

This work the radius of the coverage area was determined for the LTE network in three bands, namely 900 MHz, 1800 MHz and 2600 MHz, for the known heights of the base station and subscriber station antennas, based on the use of the Okamuri-Khata radio wave propagation model. For the most common type of Alcatel-Lucent9926 d2U equipment, coverage areas were calculated at different base station antenna gain, base station antenna (BS) suspension heights, and mobile station (MS) antenna heights. Based on the calculations and graphs, we can conclude that the optimal height of the base station antenna suspension for the frequency bands 900 MHz, 1800 MHz and 2600 MHz will be 50 m and the receiver power is 18 dBi, because with increasing BS height, fading occurs when interference decreases and, accordingly, the attenuation also declines. Accordingly, with such parameters, it is possible to transmit a signal at a distance of up to one kilometer in the case of the 2600 MHz band, up to 2.5 km in the 1800 MHz band and more than 3 km for the 900 MHz band.
