Item Assessment of Quality of Service of G.S.M. Networks in Ilorin Metropolis, Nigeria.(Afe Babalola University, Ado-Ekiti, Nigeria., 2020-06-30) Surajudeen-Bakinde, N. T; Adeniji, K. A; Oyeleye, S. O; Zakariyya, O. S; Olayanju, S. A; Usman, A. MFollowing the rollout of GSM services across Nigeria, the socio-economic landscape of the country has been positively altered. Its explosive growth has brought huge revenues to the operators, as well as the government and at the same time benefited the citizens in many ways. However, the principal developmental factors that has continued to mar these benefits is the aggressive complaints from GSM subscribers regarding the horrible Quality of Service (QoS) rendered by the GSM operators across the country. As the number of subscribers of GSM in Nigeria increased, congestion rates also increased and there has been a huge demand for a decent QoS in the country. In this study, three key performance indicators (KPI) parameters, call setup success rate (CSSR), received signal level (RSL) and call drop rate (CDR) were used in assessing the performance of two of the major GSM networks in Ilorin Metropolis of Nigeria, which have been tagged Network “A” and Network “B”. A and B monitored are far from providing reliable services to Nigerians. None of the networks in the study met the ≥ 98% CSSR required by the N.C.C. regulations, and none met the ≤ 2% CDR required by the N.C.C. regulations. The problems GSM operation encountered have been attributed to a number of challenges, with cited faults ranging from the Network providers, to regulatory agencies, and even to the Nigerian Government.Item Assessment of Quality of Service of GSM Networks in Ilorin Metropolis, Nigeria(Published by College of Engineering Afe Babalola University, Ado-Ekiti (ABUAD), Ekiti State, Nigeria., 2020-06-30) Surajudeen-Bakinde, N.

S; Olayanju, S. A; Abara, I. E; Salami, A. F; Sadiq, B. O; Alao, R. AThis paper presents the design and implementation of a low-cost, low-complexity, energy-efficient controller with remote recharge and load shedding capability. The system is recharged remotely by an SMS sent to a registered SIM card in a GSM module, a voltage and current sensor measures the load power usage, a microcontroller is used to keep track of the power consumption and signals the relay in order to execute the load shedding when the predetermined threshold is reached. The whole system is powered by a power supply unit which converts the 220V AC from the supply mains to a 5V DC. After the design and upon testing, the energy measurement circuit worked with minimal error, the relay switch executed the load shedding function without delay, the GSM showed good network reception and the operation of the system was cheap and simple thus satisfying the objective of the research.Item An Improved U-Slot Based 1 X 2 Triple Band Antenna Array for Flying Ad-hoc Networks (FANETs)(Faculty of Technology Education, Abubakar Tafawa Balewa University Bauchi, Nigeria, 2017-12) Sadiq, B. O; Zakariyya, O. S; Olayanju, S. A; Adedokun, A. EThe objective of this paper is to design an improved U-Slot based 1 X 2 triple band antenna array for Flying Ad-hoc Networks (FANETs). The purpose of this modification is to increase the bandwidth and gain of the existing 1 X 2 triple band antenna array. This is because high bandwidth and gain are essential requirement for UAVs in FANET. However, to achieve this, the resonating frequency needed to be selected appropriately. The proposed antenna array resonates at 3.2GHz, 5.1GHz and 6.4GHz frequency band respectively. The antenna is optimized using a U-Slot resonating at triple-bands by introducing two symmetrical slits at the non-radiating edges of the patch. Simulation results were achieved using CST Studio and showed that the antenna has a bandwidth of 313MHz, 51MHz and 167MHz for the three bands respectively. This implies that practical applications can be achieved using this antenna.Item Introduction to Electrical and Electronics Engineering Discipline.
