Network Planning Optimization of Long Term Evolution Radio Transmitter Using Taguchi's Method

Long Term Evolution (LTE) is newest technology for mobile telecommunication, it has some advantages that are high data rates, low latency and using all Internet Protocols (IP) network architecture. The implementation of LTE requires high cost and takes a long time therefore we need network planning to reduce the risks, some calculations, simulations and optimization is done in network planning. We use software named Atoll as tool for network planning and use Taguchi's Method (TM) as optimization technique. The objective of this paper is to obtain the optimal parameters value of azimuth, mechanical downtilt, antenna gain and antenna height. The result is the responses that determine the most influential factors due to result depending on their delta value. From this paper, the most influential factor based on SN ratio is antenna height which have delta value 9.47. Then we implement the optimized LTE radio transmitter parameters into LTE network design. The result gave more 12.2% coverage area by signal level, increase average signal received power by 0.69 dBm and increase the coverage area by throughput downlink by 1.5%.
