▼ Despite interest from policymakers and the telecommunications sector to deliver superfast broadband to the whole of the UK, rural areas remain underserved, decreasing their ability to benefit from broadband-enabled services. Public intervention, primarily structured as national subsidies, is active across the UK to respond to this rural market failure. Complementing such practices are local-level strategies framed as community-led broadband initiatives. Their inclusion within wider superfast broadband installation strategies has not yet been examined. This doctoral research examines two of these initiatives, their structure and impact on the community to develop an understanding of their potential as replicable rural broadband delivery mechanisms. I analyse both the process of installing superfast broadband technology from community-led perspective and the subsequent engagement with superfast broadband through a qualitative longitudinal approach. A conceptual framework of 'social resilience' is developed as a contemporary analytical tool for examining these individual and community processes. The findings reveal an inherent complexity to rural community-led broadband provision. Community-led broadband reflects a 'localism' development approach, and this process has strengthened local rural identity. Following the adoption of superfast broadband, rural users experienced a growth in digital knowledge and individual resilience. However, the initiatives themselves are often discussed as 'separate from', or incompatible with, the telecommunications industry, as well as sitting outside the scope of current government interventions. In doing so, barriers to external networking and extra-local partnerships are built, limiting the opportunities for community-led broadband networks to become a substantive part of rural broadband delivery across the UK. Throughout the thesis, an understanding of these various tensions, impacting the success, use and replicability of rural community-led broadband, is developed and community-led broadband is shown to be another example of uneven rural development. I conclude by making recommendations for future digital policy interventions in the UK.

▼ The use of electrical networks for telecommunications has a long history. It has been known since the beginning of the twentieth century [Ahola03]. The idea of using electrical networks for broadband communications arose in the 1990s [Hrasnica et al 04]. Recent and growing research interest has indicated that PowerLine Communications (PLC) is the threshold for achieving broadband delivery particularly in very dispersed and low teledensity areas. Currently, there are numerous PLC trials and commercial deployments underway inside and outside South Africa. Nevertheless, these PLC deployments are very isolated, done without clear methodology and performance remains bound to the physical layout of the electrical network. Because of that high bandwidth broadband PLC systems are prone to poor performance and this in turn limits the acceptance and deployment of this emerging alternative broadband technology. Though, PLC technical challenges are being addressed, there has been little analysis and research work that is focused on the “Development of Methodologies for Deploying and Implementing Local & Medium Area Broadband Power Line in Residential and Office Electric Grids” that would lead to broadband PLC being adopted and be of greater use to non-broadband communities of South Africa. PLC is a term describing several different systems using electrical grid distribution wires for simultaneous distribution of data by superimposing an analog signal [Hrasnica et al 04]. The research proposed and presented broadband PLC methodologies for typical medium voltage and local voltage PLC networks. These methodologieswere implemented and experimented with in configurations which closely mirrored residential and office settings through laboratory and multibuilding experiments using commercial 2nd Generation Mitsubishi Electric PLC technology. Research results presented not only serve to provide insight into broadband PLC but also how it handled broadband applications (communications), competed and compared with other technologies such as Ethernet LAN. In combination with networking communication theories, the research explored and analyzed the extent of PLC in providing broadband communication to residential and office electric grids at the University Fort Hare, Computer Science Department.

▼ The ever-growing demand for higher bandwidth broadband communication has driven transistor operation to higher and higher frequencies. However, achieving cut-o frequencies in the terahertz regime have been unsuccessful with the current state-of-the-art transistors exhibiting no better than 800 GHz. While the high-frequency transistor eld is dominated by III-V semiconductors, it has been proposed that graphene may be a competitive material. Graphene exhibits electron and hole mobilities orders of magnitude larger than conventional semiconductors and has an atomically thin form factor. Despite these benets, high-frequency graphene transis tors have yet to realize high-frequency characteristics better than III-V's. This thesis expands on the current limitations of graphene transistors in terms of improved fabrication techniques (to achieve higher carrier mobilities and lower contact resistances) and fundamental, band structure limitations (like quantum capacitance and the zero energy band gap). First, graphene, fully encapsulated in hexagonal boron-nitride crystals, transistors are fabricated with self-aligned source and drain contacts with sub-100 nm gate lengths. The encapsulation technique shields the graphene from the external environment so that graphene retains its intrinsic high mobility characteristic. In this short-channel regime, transport is determined to be ballistic with an injection velocity close to the Fermi velocity of graphene. However, the transconductance and output conductance are only 0.6 mS/mm and 0.3 mS/mm, respectively. This lack-luster performance is due to a relatively thick (3.5 nm) eective oxide thickness but also due to the eects of quantum capacitance which diminishes the total gate capacitance by up to 60%. Furthermore, the output conductance is increased due to the onset of hole conduction which leads to a second linear regime in the I-V characteristic. This is a direct consequence of graphene's zero energy band gap electronic structure. Finally, the source and drain contact resistances are large, which leads to poorer output current, transconductance and output conductance. Second, improvement to the contact resistance is explored by means of using graphite as the contact metal to graphene. Since graphite is atomically smooth, a pristine graphite-graphene interface can be formed without grain asperities found in conventional metals. Graphite is also lattice matched to graphene and exhibits the same 60 symmetry. Consequently, it is discovered that the graphite-graphene contact resistance exhibits a 60 periodicity, with respect to crystal orientation. When the two lattices align, a contact resistivity under 10 Wmm² is observed. Furthermore, contact resistivity minima are observed at two of the commensurate angles of twisted bilayer graphene. Though graphene transistor performance is band structure limited, it may still be possible to achieve competitive high-frequency operation by use of h-BN encapsulation and graphite contacts.

▼ Over the last few years, with the rise of phablet devices, there has been a tremendous growth in mobile data demand, followed by increased investments in development of the network infrastructures. However, rapid development of technologies to support the inevitable traffic surge poses new challenges to mobile network operators (MNOs) in terms of revenue. If MNOs want to turn the intriguing opportunity of such a large market into revenue uplift, they should scramble on multiple fronts such as cutting the operational expenditure costs, increasing the average revenue per user for the current customers and enhancing the acquisition of new customers, etc. In this thesis, a variety of deterministic and stochastic optimization techniques aimed at providing innovative solutions for such challenges are explored. In particular, we focus on tractable theoretical methods to analyze, model and dynamically optimize network planning and operation for the heterogeneous cellular networks in the following problems: (i) resource allocation, (ii) base stations management and, (iii) user association. Unlike most of existing literature, we address practical implications and limitations in our analytical modelings. Our theoretical findings provide insightful theories and novel closed-form expressions for system parameters that can be integrated in other general models developed for cellular networks. The key contributions can be summarized as (i) optimally solving instantaneous resource allocation problem previously identified as NP-hard under different formulation (ii) stochastic queue modeling of heterogeneous users followed by a tractable and tight convex approximation for it (iii) joint optimization of 3-tuple system parameters to manage base stations in a large-scale heterogeneous network (iv) deriving closed-form expression for cell-load which provides significant insights for base station sleep strategies (v) developing an optimal distributed user association that bypasses need for a centralized unit. Our analytical solutions are corroborated by extensive numerical simulations.

▼ Significant differences in mobile broadband penetration rates exist among countries. This dissertation studies whether public policies influence these differences. It does so by examining the factors that are related to mobile broadband penetration. Within this framework, it aims to understand what kind of policies/regulations, if any, are necessary and/or sufficient conditions for higher mobile broadband (high speed mobile Internet) penetration rates. Although many studies have probed the factors influencing fixed broadband penetration, few studies have focused on mobile broadband. Because policy, supply, and demand factors interact with each other, it is difficult to examine the complexity of multiple interactions among these factors by only using economic approaches or case studies. In order to capture the complicated interactions among these factors, Qualitative Comparative Analysis (QCA) was utilized in addition to econometric approaches to analyze the policy and economic factors that affect mobile broadband penetration. This allows a detailed examination of how broadband-related regulations/policies and other economic factors (both on the supply and demand side of broadband markets) affect mobile broadband penetration in OECD (Organisation for Economic Co-operation and Development) countries.Using QCA, the dissertation found six necessary conditions for higher mobile broadband penetration: 1) technology neutrality, 2) higher quality of regulation, 3) higher fixed broadband penetration rates, 4) higher mobile competitive intensity, 5) higher urban population, and 6) higher education. Analyzing sufficient conditions showed several paths for a country to have higher mobile broadband penetration, all of which were combinations of factors. This indicates the complexity of the interaction of various conditions for mobile broadband penetration. According to the sufficient solutions, high education, high income, higher fixed broadband penetration, a competitive mobile market, and higher urban population were the most important factors for a country to have higher mobile broadband penetration rates. The results of econometric analyses were largely consistent with these findings and also found income, education, and competition to be important determinants of mobile broadband penetration. Overall, the dissertation shows that policy makers may be able to contribute to increased mobile broadband penetration if they can improve the six conditions necessary for such an outcome. However, it is more difficult to find conditions that are sufficient. The analysis suggests that the sufficient conditions to improve mobile broadband penetration vary depending on the specific circumstances. For example, if a country does not have high income, it is important for the government to include mobile broadband into the universal service objective. Although some factors can be affected by policy makers in the short run or long run, some factors such as education are outside of the remit of broadband regulators and therefore require broader… Advisors/Committee Members: Bauer, Johannes M, LaRose, Robert, Wildman, Steve, Lacy, Stephen, Candeub, Adam.

▼

The explosive demand for high data rate wireless services cannot be sustained through improvements in PHY layer technologies alone. Opportunistic use of additional bandwidth through dynamic spectrum access and densification of wireless networks are necessary to meet this increasing demand, and this dissertation covers both these aspects. The first part of the thesis focuses on a cooperative spectrum access scenario where nodes exchange non-contiguous spectrum chunks as incentives for cooperative forwarding. An autonomous network is considered where each node gets an initial amount of bandwidth, and uses this bandwidth as a flexible incentive for two hop relaying. This dissertation proposes an incentivized forwarding based resource allocation algorithm which maximizes the global utility of the network while preserving the initial utility of each cooperative node. The second part of the thesis studies power optimal non-contiguous spectrum access. Non-Contiguous Orthogonal Frequency Division Multiple Access (NC-OFDMA), a popular technique in software defined radio research, accesses non-contiguous spectrum chunks by nulling intermediate spectrum. However, nulling subcarriers increases the sampling rate (spectrum span) which, in turn, increases the power consumption of radio front ends. This dissertation characterizes this trade-off from a cross-layer perspective, specifically by showing how the slope of ADC/DAC's power consumption versus sampling rate curve influences scheduling decisions in a multi-hop network. The final part of the thesis focuses on two aspects of small cell network design: (i) a prototype wireless channel measurement system that allows network operators to measure path loss and multipath fading characteristics between multiple candidate small cell locations and their potential users; and (ii) joint cost optimal aggregator node placement, power allocation, channel scheduling and routing for wireless backhaul network of small cells.

▼ Recently, mm-wave applications in CMOS have become feasible and attractive thanks to the aggressive scaling of CMOS technology. W-band frequency, which is defined from 75GHz to 110GHz, is suitable for imaging and radar applications due the small wavelength of EM wave and high detection resolution. The imaging and radar system can be widely used for applications such as medical imaging, security imaging and anti-collision radar. For these applications, a signal source with high output power and high purity is needed to work as the transmitter. However, there are many challenges to implement the W-band transmitters in the low-cost CMOS process. Firstly, a high-purity local oscillator (LO) is required, which is normally designed as the phase-locked loop (PLL). To properly lock the PLL, a mm-wave frequency divider chain is needed with wide locking range. Besides, a voltage-controlled oscillator (VCO) with good phase noise and wide tuning range is also required to operate at mm-wave frequency. Secondly, a power amplifier (PA) with high output power and efficiency is needed to generate and radiate the high-power signal to increase the operation range of the imaging and radar system. As the operation frequency is close to f_max, the maximum available gain of the transistor will drop, which makes the design of PA very challenging. In the first part of this dissertation, the building blocks of mm-wave LO generation are discussed. Several novel circuits are proposed to overcome the challenges of mm-wave PLL. Specifically, frequency-tracking injection-locked frequency divider (ILFD) is proposed to achieve ~40% locking range at 60GHz, which is the widest among existing solutions. Two ILFDs based on transformer-distribution tank are also proposed and designed to achieve comparable locking range with lower cost. The proposed two ILFDs are the first to achieve FoM (=locking range/power consumption) higher than 10GHz/mW with small chip area. To further save power, an ultra-low-power ILFD is also proposed consuming only 0.44mW power with comparable locking range. Moreover, the injection-saturation problem is also observed, discussed and solved in this work. In addition to ILFDs, switched-transformer technique is also proposed to enhance the tuning range of mm-wave VCO with competitive phase noise. The proposed switch-transformer VCO can operate at two bands to achieve >20% tuning range with FoM_T of -187dBc/Hz and has very simple scheme for cascading, which is suitable for PLL integration. Secondly, an ultra-low-power PLL operating at 50/100GHz is designed and demonstrated. The PLL measures competitive phase noise of -94dBc/Hz at 1MHz offset with only 14.1mW power consumption, which makes it suitable for the LO generation of W-band imaging/radar transmitters. Besides, embedded phase shifter is designed and demonstrated in the PLL. The output phase of PLL can be tuned continuously to cover 360° phase shift with 3.9° resolution. The amplitude variation of PLL output is less than 0.1dB across the total phase…

▼ Satellite broadband has the potential to provide Internet connectivity to people and places that are unreachable using other wired/wireless technologies. It is therefore a critical component of any service seeking to provide universal coverage. A universal service needs to support a range of Internet applications. While there is existing work on bulk and interactive applications with a characteristic transmission rate, popular Internet applications such as web browsing, web video download or variable-rate voice result in a network traffic that varies its transmission rate. This thesis first investigates the interaction of satellite resource request mechanisms with the quality of service offered to these variable-rate applications using a satellite platform based on DVB-RCS2. It shows that a flexible QoS architecture can be achieved by a combination of resource request methods and network-layer queuing. Variable-rate traffic also poses challenges to the widely deployed Transport Control Protocol (TCP). Previous work analysed the interaction with the congestion control algorithms and proposed Congestion Window Validation (CWV) to constrain the congestion window to the amount of traffic a transport has sent. TCP JAGO studied this problem for variable-rate bursty applications and proposed new algorithms; but these were shown to have drawbacks and there were no guidance on how to implement. This thesis therefore presents, newCWV, a practical mechanism to provide an appropriate estimate of the available path capacity and corresponding congestion control behaviour. This benefits variable-rate applications with shorter transfer durations, but has a consequence of allowing larger traffic bursts into the network that can increase packet loss. Burst mitigation techniques, such as TCP pacing, are proposed to deal with this. These techniques are implemented and tested in the Linux TCP/IP stack, where newCWV improves the burst transfer time. This benefit is particularly significant for the large delay of broadband satellite systems.

M.Ing.

Over the past few years, fibre Bragg gratings have emerged as very important components in the photonics environment. Their discovery has greatly revolutionised the design of many complex devices, introducing simplicity and cost effectiveness. Extensive research has been invested into identifying possible areas of application for fibre Bragg gratings. This has resulted in fibre Bragg gratings finding a comfortable niche in the fields of sensors and optical communication systems. This study focuses on the possible application of fibre Bragg gratings in wireless local area networks. Wireless local area networks are rapidly becoming a market of great potential for the investor. To sustain the impressive image of this market, research initiatives should strive to secure cost-effective solutions for the implementation of wireless local area networks. With reduced costs on wireless local area network products, the demand for these products is expected to escalate. Research conducted at the COBRA Institute, has produced a novel concept of optically distributing data signals across a network, and later transmitting them at radio frequencies between antenna sites. This concept, earmarked for wireless local area networks, uses a fast tuneable laser source, graded index polymer optical fibre and a periodic optical filter to generate the radio frequency microwave signals. The periodic filter in this network system serves to up-convert the frequency of the signal to radio-frequency levels. The filter is an important component of the network and it is situated at the antenna site. For wireless local area networks that require broad coverage, the number of periodic optical filters deployed for the system can be high. This can have a negative impact on the cost of the network. This research proposes a low-cost Fabry-Perot filter designed from fibre Bragg gratings, to replace the optical periodic filter discussed in the network mentioned above. The work presented in this study consolidates the design theories of Fabry-Perot filters and fibre Bragg gratings. The grating-based Fabry-Perot filter is modelled using coupled-mode theory, simulated using the transfer matrix method and fabricated via the strain controlled phase mask technique. The figures of merit that describe the spectral performance of the Fabry-Perot filter (i.e. free spectral range, minimum resolvable bandwidth, finesse and contrast factor) are compared to calculations associated with classical designs. The final part of this study presents experimental measurements of the generated radio frequency microwave signal. The purpose of these measurements is firstly to demonstrate the feasibility of the entire concept of generating radio frequency microwave signals using optical frequency multiplication. The second goal for the measurements is to benchmark the performance of the new grating-based Fabry-Perot filter against expected results approximated through calculations. Both goals were achieved with encouraging observations.

M.Phil. (Electrical & Electronic Engineering)

Without any doubt, the entire range of voice and TV signals will migrate to the packet network. The universal addressable mode of Internet protocol (IP) and the interfacing framing structure of Ethernet are the main reasons behind the success of TCP/IP and Ethernet as a packet network and network access scheme mechanisms. Unfortunately, the success of the Internet has been the problem for real-time traffic such as voice, leading to more studies in the domain of Teletraffic Engineering; and the lack of a resource reservation mechanism in Ethernet, which constitutes a huge problem as switching system mechanism, have raised enough challenges for such a migration. In that context, ITU-T has released a series of Recommendation under the umbrella of H.323 to guarantee the required Quality of Service (QoS) for such services. Although the “utilisation” is not a good parameter in terms of traffic and QoS, we are here in proposing a multiplexing scheme with a queuing solution that takes into account the positive correlations of the packet arrival process experienced at the multiplexer input with the aim to optimize the utilisation of the buffer and bandwidth on the one hand; and the ITU-T H.323 Endpoints and Terminals configuration that can sustain such a multiplexing scheme on the other hand. We take into account the solution of the models from the M/M/1 up to G/G/1 queues based on Kolmogorov’s analysis as our solution to provide a better justification of our approach. This solution, the Diffusion approximation, is the limit of the Fluid process that has not been used enough as queuing solution in the domain of networking. Driven by the results of the Fluid method, and the resulting Gaussian distribution from the Diffusion approximation, the application of the asymptotic properties of the Maximum Likelihood Estimation (MLE) as the central limit theorem allowed capturing the fluctuations and therefore filtering out the positive correlations in the queue system. This has resulted in a queue system able to serve 1 erlang (100% of transmission link capacity) of traffic intensity without any extra delay and a queue length which is 60% of buffer utilization when compared to the ordinary Poisson queue length.

▼ The rapid development of satellite and wireless communications pose extraordinary demands on broadband circularly polarised (CP) antenna elements and high-performance antenna arrays. The use of high-dielectric-constant materials as the substrate for the driven layer and a low-dielectric-constant material as superstrate for the radiating patch overcomes the conflict between circuit integration and antenna radiation. The aim of the research presented in this thesis is to design and develop high performance singly-fed microstrip patch antennas and arrays for CP applications. Firstly, we introduce a singly-fed cross-aperture coupled patch antenna and a stacked patch antenna using high and low dielectric materials known as Type-F and Type-E elements, respectively. As the physical structure of the Type-E element is close to the conventional linearly-polarised electromagnetically coupled patch (LP-EMCP) antennas, we have also denoted it as CP-EMCP antenna. The development of CP-EMCP antennas addresses the drawbacks of the cross-aperture patch antenna. A systematic optimisation method is developed for the design of CP-EMCP elements, at which the mean frequencies of the bandwidths can be adjusted in order to achieve a wide overlaid bandwidth. Secondly, we investigate the effects of perturbation on the parasitic patch, layer displacements, material tolerances and superstrate thicknesses on the broadband performance as well as the mutual coupling of the CP-EMCP elements. Both our theoretical and experimental results show that the CP-EMCP elements are robust in performance and have a low mutual coupling. When compared to the conventional stacked EMCP antennas and to the reduced surface-wave antenna, the mutual coupling between CP-EMCP elements is lower which allows the use of small element spacings to avoid grating lobes, which therefore make these elements good candidates for high-performance CP arrays. Following a parametric study on the effect of displacements between stacked patches and the loss consideration of the coplanar feed network printed on high dielectric constant substrates, the modified Type-E elements whose parasitic patch have a zero perturbation are developed for the design of high performance CP arrays. The low mutual coupling allows short feed-lines to connect with the spatially offset elements so as to minimise the feed loss. Consequently, it became possible to develop the novel sequentially rotating feed networks which incorporate the modified elements with a small element spacing of 2/3/λₒ for the 4- and 16-element planar antenna arrays. The results indicate that these arrays have high gain, low axial ratio, high antenna efficiency low sidelobe levels, and wide overlaid bandwidth.

▼ Satellite communication has become an integral component of global access communication network due mainly to its ubiquitous coverage, large bandwidth and ability to support for large numbers of users over fixed and mobile devices. However, the multiplicity of multimedia applications with diverse requirements in terms of quality of service (QoS) poses new challenges in managing the limited and expensive resources. Furthermore, the time-varying nature of the propagation channel due to atmospheric and environmental effects also poses great challenges to effective utilization of resources and the satisfaction of users’ QoS requirements. Efficient radio resource management (RRM) techniques such as call admission control (CAC) and adaptive modulation and coding (AMC) are required in order to guarantee QoS satisfaction for user established connections and realize maximum and efficient utilization of network resources. In this work, we propose two CAC policies for interactive satellite multimedia networks. The two policies are based on efficient adaptation of transmission parameters to the dynamic link characteristics. In the first policy which we refer to as Gaussian Call Admission Control with Link Adaptation (GCAC-LA), we invoke the central limit theorem to statistically multiplex rate based dynamic capacity (RBDC) connections and obtain an aggregate bandwidth and required capacity for the multiplex. Adaptive Modulation and Coding (AMC) is employed for transmission over the time-varying wireless channel of the return link of an interactive satellite network. By associating users’ channel states to particular transmission parameters, the amount of resources required to satisfy user connection requirements in each state is determined. Thus the admission control policy considers in its decision, the channel states of all existing and new connections. The performance of the system is investigated by simulation and the results show that AMC significantly improves the utilization and call blocking performance by more than twice that of a system without link adaptation. In the second policy, a Game Theory based CAC policy with link adaptation (GTCAC-LA) is proposed. The admission of a new user connection under the GTCAC-LA policy is based on a non-cooperative game that is played between the network (existing user connections) and the new connection. A channel prediction scheme that predicts the rain attenuation on the link in successive intervals of time is also proposed. This determines the current resource allocation for every source at any point in time. The proposed game is played each time a new connection arrives and the strategies adopted by players are based on utility function, which is estimated based on the required capacity and the actual resources allocated. The performance of the CAC policy is investigated for different prediction intervals and the results show that multiple interval prediction scheme shows better performance than the single interval scheme. Performance of the proposed CAC policies indicates… Advisors/Committee Members: Walingo, Tom (advisor), Takawira, Fambirai (advisor).
