“…Path loss is a major component affecting the RF levels and hence the channel quality in any telecommunication network. Various path loss prediction models have been worked upon till date [13][14][15][16][17][18] for link budget analysis of a communication network, operating in different environmental conditions. Also as the RSRP reduces with distance, the CQI value decreases which in turn affects the spectral efficiency resulting in lower throughput.…”

In the current environment of burgeoning demand for mobile broadband, Long Term Evolution (LTE) is the most preferred wireless technology for the mobile operators. Considering the legacy multi-technology networks, operators need to strategically work upon maximizing their revenue while minimizing their cost and satisfying the subscriber's requirements as well. Operators have a choice between 2 network strategies-LTE overlay and single radio access network (SRAN). A survey carried out proved SRAN to be the optimum LTE deployment strategy considering the total cost of ownership (TCO). This paper discusses the effect on the system performance due to the up gradation of network from second generation (2G) to third generation (3G) to long term evolution (LTE) systems using Nokia Siemens Network Flexi multi-radio base stations. Measurements of RSRP (Reference Signal Received Power), SINR (Signal to Interference plus Noise Ratio) and throughput were carried out by a drive test within 2Km of the deployed site area which indicated that all the 3 parameters were affected as the user equipment moved away from the site area and towards the cell edges. This problem can be addressed by deployment of low power relay nodes, one of the promising techniques, for increasing the coverage of LTE advanced networks (the future of LTE systems).

“…A., et al, 2015). The tremendous growth of wireless communication system and especially mobile radio system requires radio coverage prediction models and mechanism (Yihuai, Y., et al, 2012). The coverage areas of broadcast stations have a significant influence on the socio-economic life of the citizenry especially in Nigeria (Akinbolati, A., et al, 2015, and Ajewole, M.O., et al, 2014) thus making this work a good feedback mechanism between the communities in the study areas and the government.…”

This study investigated the received signal strength and the propagation profiles for UHF channel 23, broadcast signal in Ondo State, Nigeria, at various elevation levels. The signal strength was measured quantitatively across the state along several routes with the aid of a digital field strength meter. A global positioning system (GPS) receiver was used to determine the elevation above ground level, the geographic coordinates and the line of sight of the various data points from the base station. Data obtained were used to plot the elevation and propagation profiles of the signal along measurement's routes. Results showed that the signal strength was strongest towards the northern parts with respect to distance compared to other routes with the same distance contrary to inverse square law. The threshold signal level for the station was 20dBµV which was recorded up to 50km line of sight from the transmitter towards the northern parts of the state where higher levels of elevation of data locations were recorded and 42km towards the southern parts with lower values of elevation. The propagation profiles for all the routes follow the elevation pattern of the study areas, with some farther locations recording higher signal strength compared to closer locations to the transmitter contrary to theoretical expectation. The overall results show that elevation above ground level is a key factor to be considered for UHF transmission and reception (location of transmitters, transmitting antenna's height, directivity and gain. Others are, transmitter output power, receiving antenna's height and gain) in the study areas.

Abstract. To fulfill the urgent requirement for ubiquitous information exchange, the infrastructure of the next-generation mobile system is developing toward a densely distributed cellular network with multiple tiers of base stations and access technologies serving users with different mobility styles and bandwidth demands. Therefore, the need for an advanced power control and interference mitigation strategy is even more prominent. This paper proposes an iterative power allocation algorithm for mobile users within a two-tier mobile network infrastructure. The algorithm is based on Newton's method and is aimed at maximizing system capacity of the whole system. Simulation results prove that, compared to the traditional power control scheme, the proposed scheme remarkably improves utilization of latent system capacity and effectively reduces user power consumptions, and the algorithm possesses a favorable performance of convergence.
