    <dct:description>&lt;p&gt;Demand for mobile broadband connectivity is significantly increasing and mobile network operators are continuously improving their network by introducing new technologies to accommodate the demand. After mobile network is operational for the first time, to maximize network performance, it is common to perform further optimization of initially planned and configured network parameters. One important category of such network parameters that incur significant network performance impact is antenna parameters that mainly include antenna tilt and azimuth. Optimization of antenna tilt and azimuth plays a major role in optimization of coverage, capacity, load balancing and interference of mobile networks. Long Term Evolution (LTE) network is operational in some parts of Addis Ababa since 2015. This thesis work reviews Addis Ababa LTE network, deployed antenna solutions and ethio telecom antenna optimization practices. The work continues by evaluating the performance of this LTE network from electrical down tilt and azimuth steering perspective. Based on observed performance, the tilt and azimuth parameters are also optimized by applying educated trial and error approach&lt;/p&gt;</dct:description>
