Alternative approach to Power Line Communication (PLC) channel modelling and multipath characterization.
(2016)Modelling and characterization of the Power Line Communication (PLC) channel is an active research area. The research mainly focuses on ways of fully exploiting the existing and massive power line network for communications. ... -
ATM performance in rural areas of South Africa.
(2005)Rural areas in developing countries span vast areas with a variety of climatic zones, vegetation and terrain features, which are hostile to the installation and maintenance of telecommunication infrastructures. Provision ... -
CDMA performance for a rural telecommunication access.
(2005)Reviews of possible telecommunication services that can be deployed in the rural areas are highlighted. These services range from narrowband to broadband. The aim of these services is to target rural Kwazulu-Natal areas ... -
Characterization and modelling of effects of clear air on multipath fading in terrestrial links.
(2013)The increased application of digital terrestrial microwave radio links in communication networks has renewed attention in techniques of estimating the probability of multipath fading distributions. Nevertheless, the ... -
Characterization and modelling of the channel and noise for broadband indoor powerline communication (plc.) networks.
(2016)Power Line Communication (PLC) is an interesting approach in establishing last mile broad band access especially in rural areas. PLC provides an already existing medium for broad band internet connectivity as well as ... -
Clear-air analytical and empirical K-Factor determination and characterization for terrestrial microwave LOS link applications.
(2013)The transmission media, that is, the atmosphere, through which terrestrial and satellite signals traverse, is irregular. Thus, one requires proper knowledge on how variations in atmospheric refractive conditions will affect ... -
Correlation of rain dropsize distribution with rain rate derived from disdrometers and rain gauge networks in Southern Africa.
(2011)Natural phenomena such as rainfall are responsible for communication service disruption, leading to severe outages and bandwidth inefficiency in both terrestrial and satellite systems, especially above 10 GHz. Rainfall ... -
Determination of rainfall parameters for specific attenuation due to rain for different integration times for terrestrial line-of-sight links in South Africa.
(2016)Currently, there have been large demand for end-user services that use large bandwidths, while requiring best throughputs; these requirements are often not realistic because of meagre allocation of radio resources. ... -
A flexible statistical framework for the characterization and modelling of noise in powerline communication channels.
(2015)One communication medium that has received a lot of interest in recent years is the power line channel, especially for the delivery of broadband content. This channel has been traditionally used to carry electrical power ... -
Human face shaped microstrip patch antennas for ultra-wideband applications.
(2019)Abstract available in pdf. -
Metasurface based MIMO microstrip antenna with reduced mutual coupling.
(2022)In this thesis, a negative permeability (μ) metasurface is used to reduce the mutual coupling of a 2-port Multiple-Input Multiple-Output (MIMO) rectangular inset fed microstrip antenna. That was designed using the transmission ... -
Performance analysis of LAN, WAN and WLAN in Eritrea.
(2006)The dissertation addresses the communication issues of interconnecting the different government sectors LANs, and access to the global Internet. Network capacities are being purposely overengineered in today's commercial ... -
Performance analysis of optical wireless communication systems in a warm-summer Mediterranean climatic region.
(2017)Abstract available in PDF file. -
Power line communication (PLC) channel measurements and characterization.
(2014)The potential of the power line to transport both power and communication signals simultaneously has been realized and practiced for over a century, dating back to the 1900’s. Since the key aspect of power line communications ... -
Power line communication impedance profiling and matching for broadband applications.
(2018)Power line communication(PLC) is a wired communication technology that has recently re- ceived a lot of attention due to its attractive prospects towards home and /or neighborhood network applications as well as smart ... -
Rain attenuation modelling for Southern Africa.
(2008)In order to address rain attenuation scattering of millimetric waves and microwave sin Botswana, we have employed a comparison technique to determine the Ro.o1 at fourteen diverse locations in Botswana. In addition we have ... -
Rain cell size attenuation modelling for terrestrial and satellite radio links.
(2011)There is need to improve prediction results in rain attenuation in order to achieve reliable wireless communication systems. Existing models require improvements or we need fresh approaches. This dissertation presents a ... -
Rain rate and rain drop size distribution models for line-of-sight millimetric systems in South Africa.
(2006)Radio frequencies at millimeter wavelengths suffer greatly from rain attenuation. It is therefore essential to study rainfall characteristics for efficient and reliable design of radio networks at frequencies above 10GHz. ... -
Study of lower sampling intervals on rainfall queue characteristics over Radio Links in South Africa.
(2017)Rainfall attenuation in tropical and subtropical regions of the world has continued to attract great interest; as there is a urgent emphasis on proper spectrum management and sharing, particularly at microwave and millimeter ...
