“…The results in china in the band 470-566 MHz and 3400-3700 MHz reveal the frequency occupancy was slightly below 0.4, which can be 39.5%, also 606-790MHz above 0.2 which can be 27%, also 1427-1527MHz above 0.1, which is 17% also from 3700-4200MHz shows above 0.6 which is 66% occupancy of the spectrum and others are far below 0.1. Ayeni et al [25] provide spatial Spectrum Utilization Efficiency Metric for Spectrum Sharing System. The work developed an analytical metric that takes into account system parameters to evaluate the efficiency of reusing a spectrum.…”

Abstract-Continuing proliferation of wireless devices exposes humanity to the reality of the twin challenge posed by finite frequency spectrum and almost infinite demand for the same frequency spectrum, necessitating the need for more ingenious spectrum management techniques. The band 2.4-2.7 GHz was originally created and classified for ISM, 3G, UMTS and WiMAX systems. It has become a frequency band which is generally used by end users due to the fact that it's inexpensive, easy to deploy and enhances frequency re-use. Quite a few measurements have been carried out in countries like France, Germany, India, Romania, UK and USA. This paper presents a study of an outdoor measurement on spectrum occupancy in both rural and urban areas in Kwara State, Nigeria, spanning across the frequency range of 2.4 GHz -2.7 GHz. The results show that the band being investigated is immensely underutilized with upper and lower occupancy values of 22.56% and 0% in urban and rural environments. These results were compared to other measurements conducted globally in this band or closely aligned bands.Index Terms-ISM band, spectrum occupancy, spectrum utilization, UMTS network.

In this work, the performance of eight prominent empirical path loss models and a localized model, in predicting path losses in build up areas is investigated. Multi electromagnetic field strength measurements were conducted, using a dedicated spectrum analyzer, along five predefined routes in Osun State, Nigeria. The measured data were compared with the model predictions. Path profile and terrain undulations effects have been observed on the received signal. For all the routes and trans models over predicted the path losses, while Ericsson model under predicted the losses. However, Hata, Davidson, Cost 231 and ILORIN models generally show promising results with varying performance. The average mean error values of 55 dB, -28.16 dB, -8.93 dB, -30.59 dB, -22.95 dB and OSOGBO transmitter for Okumra, Hata, SUI, Cost 231, CCIR, Davidson, Ericsson, EEC and ILORIN models. In terms of RMSE, the av 9.18 dB were obtained for ILORIN, Hata and Davidson models found to be similar for other transmitters i.e. OSBC, NDTV and NTA Ile Ife with varying performances among the four contending performance for the two main contending models i.e. ILORIN and Hata models. Inconsistency in terms of the performance for each model were observed, however the localized model i.e. ILORIN was found to provide optimum path loss prediction with considerable accuracy, over the other models. With the aforementioned, we believe the results and observations presented would provide guide to radio system engineers in making informed choices on the applicability and predictability of such models in the terrain of Osun State and other similar build Nigeria.

“…Secondary users utilize parts of the spectrum that belongs to primary users based on the agreements and constraints imposed by primary users so that primary users will not be affected in any negative way. The main goal of DSA is to create flexibility in the spectrum usage so that unlicensed users could have access to the parts of radio spectrum temporarily unused by licensed users and this technique is expected to increase spectrum utilization [20]. Aim of the DSA is to manage the radio spectrum by sharing it among different wireless networks over space and time to increase overall spectrum efficiency [21,22].…”

Every year that passes, new standardized and proprietary wireless communication technologies are introduced in the market that seeks to find its place within the already highly congested spectrum. Regulation bodies all around the globe are struggling to keep up with the continuously increasing demand for new bands to offer to specific technologies, some of them requiring by design an exclusive frequency band in order to operate efficiently. Even wireless bands offered for public or scientific usage like the ISM bands are becoming the natural habitat of multiple wireless technologies that seek to use or "abuse" them in order to provide even more bandwidth to their offered applications. Wireless research teams targeting heterogeneous wireless communication coexistence are developing techniques for enabling one-to-one coexistence between various wireless technologies. Can such an exhaustive approach be the solution for N wireless technologies that wish to operate in the same band? We believe that a one-to-one approach is inefficient and cannot lead to a generic coexistence paradigm, applicable to every existing or new wireless communication technology that will arise in the future. Can another approach provide a more generic solution in terms of frequency reuse and coexistence compared to the one-dimensional frequency separation approach commonly used in commercial deployments today. Can such a generic approach provide a simple and easily adoptable coexistence model for existing technologies? In this paper we present a new generic medium sharing model that solves the huge coexistence problems observed today in a simple and efficient way. Our approach is technology-agnostic and compatible with all existing wireless communication technologies and also has the capability to support emerging ones with minimum overhead.
