I.; Imam-Fulani, Yusuf Olayinka; Oloyede, A. A.; Olawoyin, L. A.; Surajudeen-Bakinde, N. T.Explosion in the demand for mobile applications those obtained based on actual measurements of the noise floor overestimates the occupancy values across all bands while the GSM 900 and 1800 MHz bands in Ilorin, Nigeria to cover a though, the International Telecommunication Union (ITU)has are examined.Spectrum measurements were conducted in the optimum prediction, 5dB above the measured average noise level should be considered as detection threshold. Furthermore, it was ITU 10 dB was found to be too conservative. Therefore, for and services necessitates the efficient utilization of the limited acceptable threshold value. In this paper, the effects of energy detection threshold techniques on duty cycle in the GSM bands provided a benchmark of 10dB above the noise level as an found that the number of frames of the sensing data do not have analytical method of determining noise level (theoretical) and most appropriate threshold value is not yet clearly stated, bandwidth of 105 MHz. Experimental results based on radio spectrum. Determination of a suitable detection threshold the probability of false alarm or failure detection. However, the Inappropriate choice of the threshold value may either increase is an important aspect of spectrum occupancy measurement. (measured) were analyzed. Findings indicated that the MaxNoise significant effect on the duty cycleItem Hybridization of OFDMand Physical Layer Techniques for Information Security in Wireless System(Sule Lamido University Journal of Science &Technology, 2023-03) Olawoyin, L. A.; Abdulrahman, M.; Faruk, N.; Oloyede, A. A.; Adeniran, T. C.; Imam-Fulani, Yusuf Olayinka; Lasisi, H. O.; Sikiru, Ismaeel Abiodun; Baba, B. A.Due to quest for high data rate, reliable and secure communication, this has motivated both wired and wireless network shown that for all the modulation schemes, the key rate increases with an increase in the reserved subcarrier bits. schemes are implemented in securing the information transfer between two legitimate parties. In the simulation, the techniques may not be acceptable for future decentralized networks due to their high complexity in implementation source data are encrypted by obfuscation with dummy data in between the encrypted data of which 52 subcarriers power, and allocation of bits among different users. Traditionally, securing data in wireless system is always at the and computation. In this work, an OFDM IEEE 802.11a wireless system is used and physical layer encryption (PLE) frequency division multiplexing(OFDM) enablesreliable transmission of various data traffic by optimizing subcarrier, conducted for four different modulation techniques i.e.,BPSK, QPSK, 16 QAM, and 64 QAM. The result obtained were considered of which 25 subcarriers are reserved for dummy data and 27 were for data. The simulation was access service providers to deploy a next-generation network with ability to meet the required need. The use orthogonal upper layer of open system interconnection(OSI) Model by using data encryption techniques. However, such Also,the security level increased when substantial percentages of the subcarriers are reserved for dummy data.Item On issues and challenges of rural telecommunications access in Nigeria(University of Eldoret, Kenya, Kyambogo University, Uganda, and Anambra State University of Technology, Nigeria, 2016) Adediran, Y.A.; Opadiji, J.F.; Faruk, N.; Olayiwola, W.B.Rural telecommunication access has to do with provision of telecommunication infrastructure in rural communities for the purpose of connectivity within communities and with the rest of the world. There has been growing interest in how to provide universal telecommunication access in developing countries. The trend in digital divide between the rural and urban areas for developing countries reveals a growing gap. Efforts are being made by developed nations to close the gap; hence, there is the need for reversal of this trend by developing nations in their pursuit of sustainable development. The rural communities in Africa, particularly in Nigeria, are strongly faced with many challenges which include extreme poverty, lack of social services and infrastructures, low level of education and health status, as well as unequal access to income opportunities. Despite the fact that telecommunications services in Nigeria could be traced back to 1851, the aforementioned factors, coupled with the difficult physical terrain in some cases, have made them lack behind the urban areas with regard to provision of telecommunications access. In this paper, issues and challenges of providing telecommunications access in the rural areas are provided. The work looks in-depth into the socio-cultural, literacy, security, infrastructure, regulatory and financial sustainability issues. Furthermore, the paper proffers some technological options/solutions to meeting the telecommunications needs of the rural communities in Nigeria within a very short, but reasonable, time.Item Opportunities for Universal Telecommunication Access in Rural Communities(Wits LINK Centre, University of The Witwatersrand, Johannesburg, South Africa., 2016) Olayiwola, W.B.; Opadiji, J.F.; Faruk, N.; Adediran, Y.A.The goal of universal telecommunication access is to make telecommunication infrastructure available to everyone irrespective of their geographical location, income level, age, gender or other discriminatory parameters. Despite substantial efforts to close the digital divide, developing countries still encounter daunting challenges in making access truly universal. In this article, the authors report on an exploratory field survey of 15 rural communities in Nigeria’s Kwara State to document their perception of the effects of rural telecoms access on their livelihoods. Results revealed mostly positive effects in respect of economic growth, poverty alleviation, health education, primary healthcare delivery, and reporting of epidemic outbreaks such as the recent Ebola crisis. However, little impact on quality of government service was recorded, as awareness of participation in governance and socio-political issues was found to be very low. The article discusses some areas in which universal telecommunications access can be expected, going forward, to address the needs of communities in rural and remote communities.Item Physical layer security using boundary technique for emerging wireless communication systems(Wiley, 2022-11-04) Sikiru, Ismaeel Abiodun; Olawoyin, L.

The trend in digital divide between the rural and urban areas for developing countries reveals a growing gap. In this paper, we discussed from a socioeconomic perspective, the various challenges facing the deployment of rural telecommunication access in Nigeria. Successes and failures of existing universal access models in developing countries are highlighted. Exploratory field survey from fifteen rural communities in Nigeria was conducted. The investigation included characterization of rural communities; impact assessment of universal telecommunication access on rural Nigeria and sustainability analysis of possible universal access models vis-à-vis models that have been tested in other parts of the world. The paper provides guidelines to the service providers and regulators in choosing appropriate universal access model to achieve the telecommunication access in rural communities efficiently and effectively considering the peculiarities of Nigeria‟s rural socio-economic landscape.Item Spatial Variability Study of Duty Cycle in GSM 900 and 1800 MHz Bands in Rural and Urban Environments(Indonesian Journal of Electrical Engineering and Informatics (IJEEI), 2019) Faruk, N.; Imam-Fulani, Yusuf Olayinka; Sikiru, Ismaeel Abiodun; Oloyede, A. A.; Adebowale, Quadri R.; Olawoyin, L. A.; Abdulkarim, A.; Adediran, Y. A.This paper examines the spatial variability of duty cycle in the GSM 900 and high negative correlations exits between urban 900 and rural 1800, and urban the regulatory bottlenecks to maximize the scarce radio resources in the 1800 MHz bands within Kwara State, Nigeria. The results show spatial abundance of unutilised spectrum within the GSM bands. Therefore, 1800 and rural 1800. There is a weak and negative correlation between rural variance in the duty cycle with average occupancies of 1.67%, 17.76%, and urban 900 MHz, rural-urban 1800. These results clearly show the correlation between rural 900/1800 MHz and urban 900/1800 MHz. But very 900 and 1800 MHz bands. Findings also show that there is very high positive 10.55% and 0.39%, 11.00% and 5.11 in therural, urban and all locations for regulatory commissions should adopt flexible spectrum reuse strategy to relax licensed bands, especially for rural network deploymentsItem A systematic review and Meta-data analysis on the applications of Deep Learning in Electrocardiogram(Springer, 2022) Musa, N; Gital, A.
