How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
It is known that determination of TV white space (TVWS) availability, in absence of geo-location databases, can be based on sensing and applying a detection threshold. In this paper we assess the availability of TVWS spectrum, using on site measurements in urban environment in Kosovo, obtained with NARDA SRM 3006 spectrum analyzer in the UHF and VH...
Signal attenuation due to path loss can significantly affect the quality of a wireless communication link. This makes path loss measurement and estimation an important aspect when designing wireless communication systems. However, accurate values for path loss are rarely readily available, as they heavily depend on a range of factors such as line-o...
With the advent of analog to digital transition in TV broadcasting, a substantial amount of spectrum has become available in TV bands. To take advantage of this, the idea for cognitive radios was introduced for two major reasons: better utilization of spectrum in urban areas and facilitation of wireless connectivity in rural areas. To achieve these...
This paper focuses on coexistence and self- coexistence challenges between secondary heterogeneous wireless networks/users sharing TV Whitespace spectrum. The coexistence problems arise from having several primary and secondary networks of different technologies cohabiting the same licensed spectrum simultaneously. The self- coexistence problems ar...
It is well known that electromagnetic radio spectrum is very expensive. This spectrum is managed by government agencies which divides it into frequency bands and then allocates bands to different types of services such as TV broadcasting, cellular telephony ,military usage etc. Lately, the increasing number of wireless technologies and rapid increa...
