چکیده
Abstract—Pathloss estimation is largely frequencydependent and its results indicate the coverage of any mobile network. The accuracy of these estimations is crucial for viable network designs and deployment. The rapid evolution of wireless communication technologies in recent decades has led to diversity in frequency bands. The need for spectrum harmonization for mobile broadband international roaming brought about the need for the refarming of the 1800MHz band from GSM to LTE. This paper investigates the impact of refarming of the 1800MHz frequency band from GSM to LTE in terms of network planning and deployment of LTE, using Okumura-Hata, COST 231 Hata and COST Walfisch-Ikegami pathloss estimation algorithms.

In this paper a design process of a broadband printed monopole antenna using stepped cut at four corners (CSFC) technique is proposed. The CSFC is a technique that four corners a patch (rectangular/square) of planar monopole antennas are cut in order to enhance the impedance bandwidth. The technique can be used to design any different types of planar monopole antenna in specific frequency range...
