Assessing Fairtrade Marketing Drivers and Market Prospects for Commodity Producers in Developing Countries
(2013-05-14)Fairtrade has received considerable research attention but little is known about marketing factors driving sales and its potential implications for sustained market access for commodity producers. To provide objective ... -
Linking Fairtrade Shopper Insights and Supply Chain Management : Implications for Global South Producers
(2013-05-14)Fairtrade supply chains lack information linking commodity producers with fairtrade shopper behaviour. This paper aims to show how supermarket loyalty card data of over 1.7 million shoppers can be analysed using pairedsamples ... -
Modeling of LTE back-hauling through OFDMA-PONs
(Institute of Electrical and Electronics Engineers (IEEE), 2013)This paper evaluates a novel mapping and scheduling scheme which allows efficient control over the quality-of-service (QoS) experienced by long term evolution (LTE) users when backhauled over an orthogonal frequency division ... -
Flexible QoS Differentiation in Converged OFDMA-PON and LTE Networks
(Optical Society of America (OSA), 2013)We propose a Weighted-DSA scheduling algorithm which allows efficient mapping of LTE QCIs over the optical queues of an OFDMA-PON. A 63ms end-end wireless packet delay has been demonstrated for QCI5 at highest network loads -
Wireless-PONs with Extended Wavelength Band Overlay
(Optical Society of America (OSA), 2010)An advanced architectural platform based on wireless-enabled PON topologies is described. Network modelling of WiMAX channel transmission, based on FDM, over a multi-wavelength, splitter-based PON has demonstrated EVMs ... -
Wireless Convergence over Next Generation OFDMA-PONs
(Optical Society of America (OSA), 2011)This paper demonstrates the feasibility of optical/wireless convergence based on DoF propagation. Network modelling results confirm the transmission of 16 CPRI signals up to 100km OFDMA-PON infrastructures achieving 40 ... -
Cooperative cyclic sleep and doze mode selection for NG-PONs
(Institute of Electrical and Electronics Engineers (IEEE), 2014)This paper presents an energy efficient medium access control (MAC) protocol exhibiting intelligent switching among optical network unit (ONU) transceiver power levels. This is implemented by introducing a new methodology ... -
Cooperative 5G Switched and adaptive receiver beamforming for fibre wireless networks
(Institute of Electrical and Electronics Engineers (IEEE), 2014)This paper introduces an eNodeB receiver beamforming technique to mitigate future 5G network uplink inter-cell interference. This technique is based on the concept of smart antennas, improving the uplink signal-to-interference ... -
Cooperative uplink Inter-cell interference (ICI) mitigation in 5G Fibre Wireless (FiWi) Networks
(Institute of Electrical and Electronics Engineers (IEEE), 2015)This paper presents a novel cooperative uplink inter-cell interference (ICI) mitigation algorithm based on joint reception at the base station using receiver adaptive beamforming in a Cloud Radio Access Network (CRAN). In ... -
SDN based millimetre wave radio over fiber (RoF) network
(SPIE (International Society for Optics and Phonotics), 2015-02)This paper introduces software-defined, millimeter Wave (mm-Wave) networks with Radio over Fiber (RoF) for the delivery of gigabit connectivity required to develop fifth generation (5G) mobile. This network will enable an ... -
Parallel dynamic subcarrier and time allocation protocol for long-reach OFDMA-PONs
(Institute of Electrical and Electronics Engineers (IEEE), 2015)A new advanced medium access control protocol is described to support 100 km reach access networks, exhibiting the required quality-of-service for next generation passive optical networks based on orthogonal frequency ... -
African Export Supply Chain Agility : A Case of the Ghanaian International Pineapple Export Supply Chain
(2013-05-14)The rapidly changing business environment presents organisational agility challenges to developing country export supply chains and imposes methodological challenges on how to measure, monitor and evaluate these agility ... -
Assessing Consumer Preference for Origin-Labelled Drinks and its Implications for the Food and Drinks Industry in Ghana
(2008-05-20)Country of produce label is an important factor that affects consumer evaluation of food and drinks on the market. The direction of international marketing for food and drink has shifted to emerging markets since developed ... -
